A Universal Compression Algorithm for Deep Neural Networks

In the past decade, deep neural networks (DNNs) have shown state-of-the-art performance on a wide range of complex machine learning tasks. Many of these results have been achieved while growing the size of DNNs, creating a demand for efficient compression and transmission of them. This talk will present DeepCABAC, a universal compression algorithm for DNNs that through its adaptive, context-based rate modeling, allows an optimal quantization and coding of neural network parameters. It compresses state-of-the-art DNNs up to 1.5% of their original size with no accuracy loss and has been selected as basic compression technology for the emerging MPEG-7 part 17 standard on DNN compression.

    Fraunhofer Heinrich Hertz Institute
    Wojciech Samek is head of the Department of Artificial Intelligence and the Explainable AI Group at Fraunhofer Heinrich Hertz Institute (HHI), Berlin, Germany. The Fraunhofer Heinrich Hertz Institute (HHI) is ranked among top 20 Artificial Intelligence Research Labs in the world. He studied computer science at Humboldt University of Berlin, Heriot-Watt University and University of Edinburgh from 2004 to 2010 and received the Dr. rer. nat. degree with distinction (summa cum laude) from the Technical University of Berlin in 2014. During his studies he was awarded scholarships from the German Academic Scholarship Foundation and the DFG Research Training Group GRK 1589/1, and was a visiting researcher at NASA Ames Research Center, Mountain View, USA. After his PhD he founded the Machine Learning Group at Fraunhofer HHI, which he has directed until 2020. Dr. Samek is associated faculty at the Berlin Institute for the Foundation of Learning and Data (BIFOLD), the ELLIS Unit Berlin and the DFG Graduate School BIOQIC. Furthermore, he is an editorial board member of PLoS ONE, Pattern Recognition and IEEE TNNLS and an elected member of the IEEE MLSP Technical Committee. He is recipient of multiple best paper awards, including the 2020 Pattern Recognition Best Paper Award, and part of the MPEG-7 Part 17 standardization. He is co-editor of the Springer book "Explainable AI: Interpreting, Explaining and Visualizing Deep Learning" and has organized various special sessions, workshops and tutorials on topics such as explainable AI, neural network compression, and federated learning. Dr. Samek has co-authored more than 150 peer-reviewed journal and conference papers; some of them listed by Thomson Reuters as "Highly Cited Papers" (i.e., top 1%) in the field of Engineering.
