Sandwiched Compression: Repurposing Standard Codecs with Neural Network Wrappers

1 code implementation8 Feb 2024 Onur G. Guleryuz, Philip A. Chou, Berivan Isik, Hugues Hoppe, Danhang Tang, Ruofei Du, Jonathan Taylor, Philip Davidson, Sean Fanello

Through a variety of examples, we apply the sandwich architecture to sources with different numbers of channels, higher resolution, higher dynamic range, and perceptual distortion measures.

Adaptive Compression in Federated Learning via Side Information

1 code implementation22 Jun 2023 Berivan Isik, Francesco Pase, Deniz Gunduz, Sanmi Koyejo, Tsachy Weissman, Michele Zorzi

The high communication cost of sending model updates from the clients to the server is a significant bottleneck for scalable federated learning (FL).

Sandwiched Video Compression: Efficiently Extending the Reach of Standard Codecs with Neural Wrappers

no code implementations20 Mar 2023 Berivan Isik, Onur G. Guleryuz, Danhang Tang, Jonathan Taylor, Philip A. Chou

We propose differentiable approximations to key video codec components and demonstrate that, in addition to providing meaningful compression improvements over the standard codec, the neural codes of the sandwich lead to significantly better rate-distortion performance in two important scenarios. When transporting high-resolution video via low-resolution HEVC, the sandwich system obtains 6. 5 dB improvements over standard HEVC.

Sparse Random Networks for Communication-Efficient Federated Learning

1 code implementation30 Sep 2022 Berivan Isik, Francesco Pase, Deniz Gunduz, Tsachy Weissman, Michele Zorzi

At the end of the training, the final model is a sparse network with random weights -- or a subnetwork inside the dense random network.

Lossy Compression of Noisy Data for Private and Data-Efficient Learning

no code implementations7 Feb 2022 Berivan Isik, Tsachy Weissman

In this sense, the utility of the data for learning is essentially maintained, while reducing storage and privacy leakage by quantifiable amounts.

LVAC: Learned Volumetric Attribute Compression for Point Clouds using Coordinate Based Networks

1 code implementation17 Nov 2021 Berivan Isik, Philip A. Chou, Sung Jin Hwang, Nick Johnston, George Toderici

We consider the attributes of a point cloud as samples of a vector-valued volumetric function at discrete positions.

Neural 3D Scene Compression via Model Compression

no code implementations7 May 2021 Berivan Isik

In this work, we take a different approach and compress a functional representation of 3D scenes.

An Information-Theoretic Justification for Model Pruning

1 code implementation16 Feb 2021 Berivan Isik, Tsachy Weissman, Albert No

We study the neural network (NN) compression problem, viewing the tension between the compression ratio and NN performance through the lens of rate-distortion theory.

Neural Network Compression for Noisy Storage Devices

no code implementations15 Feb 2021 Berivan Isik, Kristy Choi, Xin Zheng, Tsachy Weissman, Stefano Ermon, H. -S. Philip Wong, Armin Alaghi

Compression and efficient storage of neural network (NN) parameters is critical for applications that run on resource-constrained devices.

rTop-k: A Statistical Estimation Approach to Distributed SGD

no code implementations21 May 2020 Leighton Pate Barnes, Huseyin A. Inan, Berivan Isik, Ayfer Ozgur

The statistically optimal communication scheme arising from the analysis of this model leads to a new sparsification technique for SGD, which concatenates random-k and top-k, considered separately in the prior literature.
