Due to the prevalence of machine learning (ML) algorithms and the potential for their decisions to profoundly impact billions of human lives, it is crucial that they are robust, reliable, and understandable. This thesis examines key theoretical pillars of ML surrounding generalization and overfitting, and tests the extent to which empirical behavior matches existing theory. We develop novel... More >

Secure computation enables a set of mutually distrusting parties to collaboratively compute a public function over their private data while keeping those data private. A central question in the cryptography community, that has been studied for decades, is whether secure computation protocols can be efficient enough to serve for its countless applications. In this talk, I will present my efforts... More >

The information theory community has traditionally studied two different models for communication. The Shannon-theoretic model treats the channels impact as random, so codes must correct almost all error patterns of a given weight; this is an average-case analysis. The coding-theoretic (Hamming-theoretic?) model treats the channel as adversarial, so codes must correct all error patterns of a... More >

The theory of NP-hardness of approximation has led to numerous tight characterizations of approximability of hard combinatorial optimization problems. Nonetheless, there are many fundamental problems which are out of reach for these techniques, such as problems that can be solved (or approximated) in quasi-polynomial time... More >

In recent times, the field of computer vision has made great progress with recognizing and tracking people and their activities in videos. However, for systems designed to interact dynamically with humans, tracking and recognition are insufficient; the ability to predict behavior is requisite. In this talk, I will present my work on learning to make predictions from visual input. Using team... More >

Imaging biological samples under optical microscopes is challenging, since the absorption is too weak to form images with informative contrast. Besides fluorescent imaging techniques, label-free phase contrast imaging methods have been proposed to greatly improve the contrast of transparent samples. In order to efficiently recover quantitative properties, such as 2D phase projection and 3D... More >
Scientific Computing and Matrix Computations Seminar: A Backward Error Formula for the Global Least-Squares Problem
Seminar: Scientific Computing: CS | May 8 | 2-3 p.m. | 380 Soda Hall
Eric Hallman, UCB
In this talk we present formulas for the normwise backward error for the problems AX=B and min_X ||AX-B||_F, extending the results of Walden/Karlson/Sun (1998) and Sun/Sun (1997) to systems with multiple right hand sides. These formulas are valid for matrices of any dimension and rank. We also propose two estimates that numerical experiments suggest are highly reliable, one of which may be... More >

LiDAR (Light Detection and Ranging) captures high-definition real-time 3D images of the surrounding environment, which makes it a crucial sensing modality for applications such as self-driving cars. However, high price tag of existing commercial LiDAR modules based on mechanical beam scanners and intensity-based detection scheme prohibits them from being extensively applied to consumer products....

Lecture: Dissertation Talk: CS | May 8 | 4-5 p.m. | 540AB Cory Hall
While state-of-the-art machine learning models are deep, large-scale, sequential and highly nonconvex, the backbone of modern learning algorithms are simple algorithms such as stochastic gradient descent, or Q-learning (in the case of reinforcement learning tasks). A basic question endures---why do simple algorithms work so well even in these challenging settings?
This talk focuses on two... More >

Modern cloud data services aim to support increasingly sophisticated queries with interactive response times. These services can be broadly divided into two categories: read-intensive applications such as web services, and write-intensive applications such as real-time monitoring of event streams. In both cases, supporting sophisticated queries interactively and at scale raises significant... More >

It is often easier to describe what we want an autonomous system to do rather than how to do it. A control synthesizer bridges that gap by automatically constructing control software so the closed loop dynamics enforce a desired behavior such as safety or reachability. While many specific instances of control synthesis have elegant mathematical solutions, designing tractable algorithms to compute... More >

In this talk we will look at the design of 0.1gram centimeter-scale microbots utilizing different locomotion strategies as a means of transport. The focus won't be on the brain or useful payloads for these bots, but instead on the electro-mechanical design to make these tether-less, which is a necessary precursor to making autonomous microbots.
We start with the design of a micro-ratcheting... More >

I will show that the phase dynamics of sub-harmonically injection locked coupled oscillator systems are governed by a Lyapunov function that continuizes the Ising Hamiltonian.
This result is used to devise a new Ising machine scheme that can use oscillators from many different physical domains.
A demonstration of a prototype CMOS oscillator-based Ising machine of 240 spins will follow the talk.

The problem of generating a large number of diverse solutions to a logical constraint has important applications in testing, verification, and synthesis for both software and hardware. The solutions generated could be used as inputs that exercise some target functionality in a program or as random stimuli to a hardware module. The sampling of solutions can be combined with techniques such as fuzz... More >
