A La Carte Embedding: Cheap but Effective Induction of Semantic Feature Vectors
Nikunj Saunshi
12:15pm|Princeton University, CS 302

Motivations like domain adaptation, transfer learning, and feature learning have fueled interest in inducing embeddings for rare or unseen words, n-grams, synsets, and other textual features. This paper introduces a la carte embedding, a simple and...

Computer Science/Discrete Mathematics Seminar I

Classical Verification of Quantum Computations
Urmila Mahadev
11:15am|Simonyi Hall 101

We present the first protocol allowing a classical computer to interactively verify the result of an efficient quantum computation. We achieve this by constructing a measurement protocol, which allows a classical string to serve as a commitment to a...

Introduction to Query-to-Communication Lifting
10:30am|Simonyi Hall 101

I will survey new lower-bound methods in communication complexity that "lift" lower bounds from decision tree complexity. These methods have recently enabled progress on core questions in communication complexity (log-rank conjecture, classical-...

Prediction with a Short Memory
Sham Kakade
12:15pm|White Levy Room

We consider the problem of predicting the next observation given a sequence of past observations, and consider the extent to which accurate prediction requires complex algorithms that explicitly leverage long-range dependencies. Perhaps surprisingly...

Generalized Framework for Nonlinear Acceleration
Damien Scieur
12:15pm|White Levy Room

Nonlinear Acceleration Algorithms, such as BFGS, were widely used in optimization due to their impressive performance even for large scale problems. However, these methods present a non negligeable number of drawbacks, such as a strong lack of...
