30µm defects on anodized surfaces as large as 0.5m² can cause process failures for semiconductor manufacturers. Early stage defect detection during assembly is thus primordial as it prevents accruing significant losses. Our team leverages computer vision, specifically object detection, to train classification models that accurately and efficiently identify flaws on parts during in-line quality inspections. This solution is easily scalable and can be integrated into the manufacturing line, thereby replacing the current timely manual inspection and eliminating ergonomic harms to operators.

Typical 3D printing takes from 30 minutes up to 7 days or more, depending on the part. Computed axial lithography (CAL), a type of volumetric 3D printing, takes tens of minutes in comparison because it prints the object simultaneously instead of layer by layer. We are testing the boundaries of CAL through algorithm optimization, characterization of multi-material bonding, and integration of green materials which will prove that CAL can overcome constraints presented in existing 3D printing techniques. The result is a greener volumetric printing technology that allows for more versatile printing of 3D objects in a significantly shorter amount of time.

Attempts at 3-D printing biological materials are encumbered by the slow rate of the process and the “soft” nature of the material. Previous successes have invariably yielded objects no larger than a dime, as both the tendency for these materials to collapse and the need to preserve any cells confound the 3-D printing process. We are designing a level-controlled cooling bath to precisely freeze biomaterials as they are printed, thereby addressing both challenges. This new approach allows for far larger printed structures than previously possible.

Today’s AI boom has enabled rapid turnaround in scientific discoveries across life science and medical applications. However, traditional machine learning (ML) approaches are time-consuming and challenging due to the manual steps involved. We aim to accelerate scientific discovery by automating traditional ML workflows within two applications: protein design and discovery of yeast biology. Successful automation would require maintaining state-of-the-art performance. Improving performance would be an added bonus. Our approach involves utilizing and understanding the strengths and weaknesses of various automated machine learning (AutoML) frameworks. If successful, we would demonstrate that robust acceleration of scientific discoveries is feasible across various cutting-edge applications.

Simply increasing the time-steps of an ODE (Ordinary Differential Equations) degrades the performance of the neural network while increasing the inference latency. Through our analysis, we show that customizing the time-step for individual layers of the neural network using adaptive time-stepping scheme gives a better performance on image classification task on CIFAR10 dataset. We provide evidence that adaptive time-stepping does not simply learn a suitable time-step configuration for a specific neural network architecture or application, but contributes towards convergence of the neural network to a better solution. Our proposed solution can benefit IoT edge devices with memory-bound architecture for deep learning applications as it gives better performance with higher compute-to-memory-access ratio.

The design of analog integrated circuits is traditionally time-consuming due to the large amount of manual labor involved. It becomes worse when the design has to be iterated to arrive at the best solution. Berkeley Analog Generator (BAG) helps alleviate this burden by providing a Python interface between designers and the design tool. Recently, designing high-speed optical link has become of interest, as the need for higher volume of computation keeps increases. The larger volume of computation means faster communication between chips is needed. Our project aims to leverage BAG to design optical receivers fast, given a certain specification.

Training a neural network from scratch can be prohibitively expensive given the amount of computational power that it takes to train certain architectures and datasets. In some cases, parallel computing is needed to reduce the training time for particular datasets to the order of weeks. Our team is applying transfer learning to pre-trained robust neural networks. Robust neural networks are different because they’re insensitive to small perturbations in the input image. This method not only significantly speeds up the training process, but also increases classification accuracy by leveraging the network’s pre-trained experience on a separate dataset.

By 2025 there will be nearly 40 billion connected devices. As the number of internet-connected devices increases, so does interference between them, limiting their throughput. Because current wireless communication between agents is rigid, and requires a pre-established protocol, devices can’t easily work together to reduce this interference. Our team is using machine learning to teach devices how to discover a protocol optimized for their unique environment. In this way, they can learn to communicate with each other more efficiently.

Neural networks are becoming more computationally expensive, but there is a rising demand to run them efficiently on resource-constrained hardware for applications such as autonomous driving. We aim to implement a compression technique (quantization) that reduces the size and inference time of a neural network on different types of hardware. To achieve overall network speedup, our solution uses hardware-aware mixed-precision quantization to assign lower bit precisions to layers that show speedup with little accuracy drop after quantization while keeping higher precisions for layers that are more sensitive to accuracy drops after quantization.

This project applies multi-agent reinforcement learning (RL) theory to optimize the execution strategy in limit order book (LOB) trading. First, we simulate financial trading environment not only with historical data, but also with trading agent interaction in the market, to make the simulation more accurate. We train agents to capture LOB micro-structure behaviors with respect to market realism. Next, we construct RL framework to train a robust policy for LOB execution. We aim to apply model-free RL algorithm, to minimize the overall trading cost within the simulated market environment.

The Credit Default Swap (CDS) market is under regulation and there’s no obligation for buyers and sellers to report transactions. Therefore, the current CDS index transaction record is limited and hard to work with. If one owns a valid and high-quality set of CDS index records, the institution may have advantages over its competitors since CDS indices trade volume increased steadily over the past few years. We are generating synthetic CDS trade data similar to the existing record using Generative Neural Network (GANs) which includes a generator and a discriminator. To validate the synthetic dataset, we are using other machine learning models and techniques and the result shows that we achieve over 90% similarity between the real and synthetic data.

Since 2017, the beginning of speculation over cryptocurrencies, price volatility has become a barrier for daily use of cryptocurrencies, including Ripple’s XRP. In order to enhance adoption of XRP as a medium of exchange, a technical requirement is to catch and prevent behaviors that may cause unstable prices. Our team is creating a detection system to identify abnormal activities using machine learning models. We analyze unexpected events in transaction volume, fee increases, and account creation. A Slackbot will report our analysis and send timely alerts to Ripple’s engineers so they can take measures that will improve confidence in XRP value.

Approximately $300 billion (1.5% of GDP) is laundered annually through the United States, most of it connected to fraud. While financial institutions have strong security measures and regulations to combat fraud, online platforms that enable financial transactions have become a new source of illicit financial activities. Due to the unregulated nature of this emerging industry, tracking and identifying financial fraud is difficult. The Beam team is building machine learning models to preemptively flag suspicious activity so enforcement officers can take action with confidence. Our team’s models will detect suspicious financial transactions, using cutting-edge natural language processing techniques to identify anomalous groups of text messages associated with transactions.

There are many security and privacy vulnerabilities found in modern blockchain applications. Cryptocurrency trading is not as secure as you think. Decentralized cryptocurrency exchanges are vulnerable to certain exploitations like front running attacks. Machine learning can violate data privacy. Tech giants do not want to share their data but still want to benefit from each other. Some blockchain consensus suffers from insecure leader selection. PBFT, a common consensus algorithm, is vulnerable to attack related to the leader selection procedure. Therefore, our team is working on developing algorithms and systems to address those issues. Specifically, we use federated machine learning, Kyber Network’s architecture, and Snowball protocol to build an on-chain machine learning system, a front running-resistant decentralized exchange, and a PBFT-based leaderless consensus algorithm. The results will make those blockchain applications more secure and efficient.

Mobile tensegrity robots have the potential to revolutionize the field of emergency response by gathering immediate data via visual & chemical sensors. Their tensegrity structure enables movement through various terrains- enabling the robots to assist emergency responders, such as fire departments and the military, in assessing hazardous situations. Our specific project has two core goals: to improve the accuracy & functionality of the present mobile robot’s electronics, and to test the feasibility of a mobile robot whose actuation is controlled via the central payload. These improvements will facilitate proper robot locomotion and decrease the complexity required to operate the mobile robot. The tools we are using include rapid prototyping, control simulation, and sensor calibration. We hope to accomplish continuous motion for the centrally actuated prototype, and optimal control based on current sensing results for the present mobile robot design.

Applying drones to monitor on-going wildfires is a novel method to help firefighters put out fires and facilitate evacuation. Due to the limitation of drones’ electrical or fossil energy, it is necessary to plan the shortest paths for a drone swarm to deploy them efficiently.To reach the goal, machine-learning-based path planning algorithms are created to reduce the energy consumed on path as much as possible. Related high-risk wildfire location forecasts, fire propagation predictions, and drones’ computer vision scanning process are also investigated to improve drone deployment effectiveness.

The cost for seawater desalination has decreased from $0.0095/gallon in 1972 to less than $0.0025/gallon and concentrated from capital expenditure to electricity cost. However, due to electricity shortage in emergency situation, it’s difficult to produce affordable drinking water for coastal communities. To support them, we are designing a sustainable and compact wave-powered desalination system that produces 105 gallons drinkable water per day at competitive cost. Provided a daily benchmark of 3 gallons fresh water per person, this device can support community with 35 people. Our solution relies on a reverse osmosis unit powered by ocean waves, mainly composed of inflatable materials to reduce both size and cost, and a robust mooring system that ensures survivability.

About 4 billion people, more than half the world’s population, experience severe water scarcity for at least one month a year. Desalination can improve the lives of many of these people, but it typically comes at a high environmental and economic cost. Our web-based application helps any interested party quickly evaluate the economic feasibility of building a desalination system that uses renewable energy and does not pollute waterways with toxic brine discharge. Using a mathematical model we developed, our tool would give the end-user a high-level physical design of the plant along with estimated financial reports using just a few key parameters that constrain the plant’s design.

Predicting enzymatic activity is a powerful tool for effectively synthesizing and characterizing novel compounds. Current enzyme prediction algorithms infer enzyme preferences by analyzing enzyme-compatible molecules (positive substrates). However, these algorithms neglect enzyme-incompatible molecules (negative substrates). Our software, CAERS, analyzes the structure-activity relationships (SAR) of positive and negative substrates to generate an ensemble that illustrates all of an enzyme’s specificity preferences. This new approach allows CAERS to evaluate novel substrates and predict their enzyme compatibility. The result is a biologically accurate reaction prediction software. CAERS expedites compound synthesis and characterization research by generating the most biologically favorable compounds to further investigate.

Despite the development of medical records systems, there is no precise technology for large-scale information extraction, public health research and precision medicine. We designed a reliable NLP-enabled system that extracts the medical history from health records and provides users with the ability to give targeted user-input on NLP-correctness, creating an active-learning feedback loop that allows the system to continuously improve. We trained a machine learning model with user input and incorporated NLP metrics to provide confidence scores to users, enabling them to evaluate the accuracy of extracted information from cTAKES, the most commonly used system for large-scale clinical data analysis.

Osteoarthritis (OA) is a common degenerative joint disease caused by progressive loss of articular cartilage. The Centers for Disease Control and Prevention indicates that more than 30 million adults in the USA suffer from OA. We are developing a novel polymeric formulation that drives regeneration of damaged knee cartilage through cartilogenesis. We intend to treat OA using an electro-active polymer, which can be injected into the joint space of an affected knee and controlled by external electro-magnetic field to induce cellular regeneration. This offers a (i) minimally-invasive and (ii) time-saving alternative to the existing invasive knee-replacement surgery.

Affecting over 65 million people worldwide, glaucoma is a disease that creates excessive fluid pressure in the eye and eventually leads to blindness. Severe cases require surgical intervention to redirect fluid to an implant placed on the back of the eye. However, commercially available implants cost up to $1,000 each and have a 50% failure rate within a few years. The I-OPeners Team is developing a low cost, patient-specific glaucoma implant that regulates pressure for a longer duration.

In combination with Zendar’s hardware and software suite, this solution is cheaper, easier to install, and less susceptible to adverse weather conditions when compared to costly LIDARs.

US electric vehicle sales increased by 81% from 2017 to 2018. However, 58% of drivers who are unlikely to purchase an electric vehicle are influenced by factors like range anxiety. The General Motors team is developing a simulated electric vehicle test drive app that will help eliminate skepticism by providing a first-hand experience of what life would be like with an electric vehicle. The application will model a virtual electric vehicle, feed the operating conditions of the host vehicle into the model, and report the status of the emulated vehicle through the in-vehicle application user interface.

Due to increasing congestion in urban areas, there is a high demand for a new form of safe and environmentally-friendly transportation. A new type of air vehicles, electric vertical takeoff and landing (eVTOL) vehicles, are proposed to fly in urban areas to help urban dwellers travel faster. However, there are many uncertainties about this new mode of transportation because rules and regulations have not yet been determined. Our proposed solution will provide a set of flight standards for creating imaginary surfaces that guide the takeoff and landing of eVTOL vehicles in urban settings. These surfaces are designed to help aircraft avoid collision with infrastructure obstacles and minimize their noise impact.

On average, American people spend an hour daily in their cars. The undamped vehicle vibrations can have undesirable physical effects on humans. Additionally, Vibrations can cause accelerated fatigue (and in some worst-case scenarios, immediate failure!) to the mechanical components. The vibrations in the longitudinal direction of motion are prone to resonances exhibited by the components of the driveline. These vibrations can be controlled by modifying the motor torque using feedback control. This project includes exploring how some of the established control strategies could be employed to provide a robust system damping in an automotive application using a representative simulation environment.

There is a significant imbalance between jobs and housing in Silicon Valley, resulting in disruptive congestion in Fremont, as employees commute through. The main goal of the project is to mitigate the cut-through traffic in Fremont. We model the current situation to identify main causes of congestion. We use data from Fremont and Google APIs. We use Python for data processing, ArcGIS for data visualization and Aimsun for traffic simulation. We aim to adjust the simulation parameters to mitigate congestion and lessen cut-through traffic. Traffic calming measures are suggested such as adjusting traffic signal light plans and imposing turn restrictions.

Current traffic is always jammed because of the behavior of each driver. If we can design a set of behavior based on traffic algorithms to guide each driver in a way based on optimizing the whole traffic flow, the transportation jam can be mitigated. In our project, we deployed self-driving algorithms on robotic vehicles to simulate traffic flow and developed a framework to provide all the APIs like Computer Vision, Control Algorithms. We managed the traffic flow of twenty cars running on the same map with an advanced control strategy more efficiently than simulating human drivers.

Autonomous vehicles are set to be the future of transportation with many reported developments in autonomous driving systems. The need to process various sensory inputs for such systems from vehicle integrated cameras, radars and other sensors for further control and maneuver is tremendous. Team AutoDrive Vision is using a combination of Convolutional Neural Networks and other Deep Learning methods to build an image recognition algorithm capable of detecting pedestrians and vehicles for ego-vehicle. The outputs of this algorithm would enhance the perception field of ego-vehicle by increasing the accuracy of the autonomous driving system.

The implementation of electric vehicles in the transportation world has not been followed by the development of an infrastructure that can support the increased demand for electricity. In addition, the developed charging stations are poorly managed, allowing users to occupy spots even when the vehicles are not charging. Smart Electric Vehicle Charging Stations (SEVCS) approach is to allow the users to decide how they want their charging service to be delivered and manage this demand focusing on reducing the impact on the electric grid and reducing operational costs for owners. By creating pricing and charging algorithms with the implementation of machine learning and data analytics, SEVCS is able to induce certain human behavior in order to optimize the idle time and the maximum power of the station as a whole.

With current technology, even planets that are light years away had been mapped out with higher resolution than most of the seafloor on Earth. Limited by low bandwidth underwater communication, sonar is the traditional approach for underwater communication. Our team aims to use optical communication to create low cost, high bandwidth means of underwater networking between swarms of Unmanned Underwater Vehicles (UUV) for wireless communication. By modulating lasers at high frequencies, and through advanced control methods, we aim to transmit data across large stretches of open ocean at vastly faster speeds than traditional methods. Specifically, our group has been building onto our research lab’s existing UUVs to design, build, and integrate a wireless means of communicating through lasers in open ocean environments.

People spend between 100 hours to 200 hours in traffic each year in big cities, which has a negative impact on daily life due to productivity loss, air pollution and stress. Our team is optimizing traffic lights in road intersections to reduce congestion and time spent in traffic, therefore improving the overall efficiency of the system. Our solution includes a traffic model which enables us to simulate the flow of vehicles on roads and in intersections.Within this model, we use Reinforcement Learning to find optimal strategies to control traffic lights.

Commuters everywhere experience frustration and delays due to traffic congestion. Dense urban areas such as San Francisco create the largest problems. The general solution is to expand infrastructure but this is expensive, time-consuming, and politically complicated. Instead, our team will reduce delays by optimizing traffic signal sequences with sophisticated simulations of the street traffic conditions .With better traffic control we can provide an inexpensive and easily implemented relief to commuters.

The average person spends more than an hour sitting in traffic every day in San Francisco. This has a huge impact on public health, economic productivity, and pollution; in a world where both qualities of life and environmental concerns are at the forefront of public debate. We are using cutting edge machine learning technology to build an open-source transportation-planning decision support system that will enable policymakers to make informed decisions about bridge tolls, public transportation schedules, and financial incentives; taking into account all involved stakeholders (such as citizens, elected officials, and the environment). This will allow transportation authorities to optimize traffic in a way that reduces pollution, delays and financial costs for daily commuters.

According to the Occupational Safety and Health Administration (OSHA), almost 2 million U.S. workers suffer from Repetitive Strain Injuries (RSI) such as carpal tunnel syndrome or tendinitis. These impairments hinder an individual’s ability to use a traditional computer mouse. By utilizing a webcam, users will be able to manipulate a cursor at a low cost and without touching a physical device. This is achieved by employing computer vision techniques and machine learning algorithms. Key points of the hand are extracted from the image and used to generate a feature set to train a model to map gestures to cursor actions.

Optical defocus problems like nearsightedness and farsightedness affect the vision of millions worldwide, preventing them from reading displays without prescription lenses. A Vision Correcting Display (VCD) allows users to clearly see images without additional correction by changing the image according to the user’s prescription. Existing VCD algorithms are designed to correct general optical problems, making them inefficient and complex. We narrow our scope to only correct optical defocus by modularizing previous VCD research and utilizing raytracing and Gaussian optics models. As a result, our VCD algorithms have improved computational efficiency while still maintaining image quality.

According to the World Health Organization, globally at least 2.2 billion people have vision impairments. Vision correcting display provides an alternative way for people with vision impairments to see a digital screen clearly, without any eye wears or undergoing surgeries. However, Vision Correcting Display algorithm requires the user to have a fixed viewing position. To eliminate the spatial limitations, our capstone project adjusts this technology to allow flexible user positions with computer graphics and ray-tracing techniques. We use retinal light field projection to compensate for the optical blurring. This project could become a transformative technology that has a profound impact on how we interact with digital devices.

The industrial trend for autonomous robots is to develop ever more sophisticated self-navigation algorithms and systems as an endeavor to ultimately remove human control. However, most of the self-navigation systems today are not entirely reliable, meaning the possibilities of collision still stands despite the effort of object avoidance algorithms. We assume that under certain circumstances, introducing human control for autonomous systems could increase the level of safety and that semi-autonomous robot navigation would better fit into the current social context. Based on an implementation of a pedestrian path prediction algorithm, we developed an augmented reality system to visualize the prediction result as a visual cue for the robot operator to adjust robot navigation strategies accordingly.

Cells in the human retina have spectral sensitivities that prevent them from being individually stimulated by natural light. As a result, humans cannot perceive all possible colors. For the colorblind, this range is limited even further. The Oz Vision project is developing an adaptive optics system to stimulate individual cells in the eye. Our team upgraded the system software to project a wider field-of-view centered on the retinal focal point and include video playback capabilities, allowing a subject to freely gaze over the displayed stimulus. This will facilitate more immersive experiments that will push the boundaries of vision science and enable the perception of new colors, for normal and colorblind subjects alike.
