The Unreasonable Effectiveness of Linear Prediction as a Perceptual Metric

1 code implementation6 Oct 2023 Daniel Severo, Lucas Theis, Johannes Ballé

We show how perceptual embeddings of the visual system can be constructed at inference-time with no training data or deep neural network features.

Random Edge Coding: One-Shot Bits-Back Coding of Large Labeled Graphs

1 code implementation16 May 2023 Daniel Severo, James Townsend, Ashish Khisti, Alireza Makhzani

We present a one-shot method for compressing large labeled graphs called Random Edge Coding.

Action Matching: Learning Stochastic Dynamics from Samples

1 code implementation13 Oct 2022 Kirill Neklyudov, Rob Brekelmans, Daniel Severo, Alireza Makhzani

Learning the continuous dynamics of a system from snapshots of its temporal marginals is a problem which appears throughout natural sciences and machine learning, including in quantum systems, single-cell biological data, and generative modeling.

Compressing Multisets with Large Alphabets using Bits-Back Coding

1 code implementation15 Jul 2021 Daniel Severo, James Townsend, Ashish Khisti, Alireza Makhzani, Karen Ullrich

Current methods which compress multisets at an optimal rate have computational complexity that scales linearly with alphabet size, making them too slow to be practical in many real-world settings.

Regularized Classification-Aware Quantization

1 code implementation12 Jul 2021 Daniel Severo, Elad Domanovitz, Ashish Khisti

Our method performs well on unseen data, and is faster than previous methods proportional to a quadratic term of the dataset size.

Improving Lossless Compression Rates via Monte Carlo Bits-Back Coding

1 code implementation ICLR Workshop Neural_Compression 2021 Yangjun Ruan, Karen Ullrich, Daniel Severo, James Townsend, Ashish Khisti, Arnaud Doucet, Alireza Makhzani, Chris J. Maddison

Naively applied, our schemes would require more initial bits than the standard bits-back coder, but we show how to drastically reduce this additional cost with couplings in the latent space.

Ward2ICU: A Vital Signs Dataset of Inpatients from the General Ward

2 code implementations2 Oct 2019 Daniel Severo, Flávio Amaro, Estevam R. Hruschka Jr, André Soares de Moura Costa

We present a proxy dataset of vital signs with class labels indicating patient transitions from the ward to intensive care units called Ward2ICU.
