Exploiting Inductive Biases in Video Modeling through Neural CDEs

no code implementations8 Nov 2023 Johnathan Chiu, Samuel Duffield, Max Hunter-Gordon, Kaelan Donatella, Max Aifer, Andi Gu

We introduce a novel approach to video modeling that leverages controlled differential equations (CDEs) to address key challenges in video tasks, notably video interpolation and mask propagation.

Variable Length Embeddings

1 code implementation17 May 2023 Johnathan Chiu, Andi Gu, Matt Zhou

In this work, we introduce a novel deep learning architecture, Variable Length Embeddings (VLEs), an autoregressive model that can produce a latent representation composed of an arbitrary number of tokens.

Modeling Image Quantization Tradeoffs for Optimal Compression

no code implementations14 Dec 2021 Johnathan Chiu

All Lossy compression algorithms employ similar compression schemes -- frequency domain transform followed by quantization and lossless encoding schemes.

Formal Analysis and Redesign of a Neural Network-Based Aircraft Taxiing System with VerifAI

no code implementations14 May 2020 Daniel J. Fremont, Johnathan Chiu, Dragos D. Margineantu, Denis Osipychev, Sanjit A. Seshia

We demonstrate a unified approach to rigorous design of safety-critical autonomous systems using the VerifAI toolkit for formal analysis of AI-based systems.
