Speaker: Scott Le Grand

This talk is a gentle introduction to Amazon open sourced deep learning library DSSTNE. The creation of DSSTNE is motivated by the massive scale and low latency computing needed for Amazon scale catalog and recommendation production problem. It is also motivated by the inherent extreme sparseness of recommendation or data sets in Amazon. In this talk Scott will walk through such requirements for a new (better) deep learning frame suitable for large scale production use. He will delineate a few considerations and solutions of how DSSTNE address those challenges. He will also briefly introduce DSSTNE’s API and how it can be used to easily reproduce the state of art deep nets topologies e.g. Alex Net.  This talk also includes DSSTNE’s performance compared to TensorFlow and compared to other machine learning algorithms on benchmark datasets.

Bio:  Scott Le Grand is currently a senior scientist in Tezza Technology. He is the lead author of DSSTNE (Deep Sparse Scalable Tensor Network Engine). DSSTNE is an Amazon developed library for building Deep Learning (DL) machine learning (ML) models, and in one of forces powering the personalization of the gigantic Amazon retail business. Besides the creation of DSSTNE, Scott is also leading the effort of optimizing Deep Neural Network (DNN) performance on GPUs and GPU clusters and applying DSSTNE to general machine learning, deep learning and analytical applications.

Scott has been an expert in developing large scale distributed algorithms and systems. He developed life science services on Amazon’s Elastic Compute Cloud (EC2) as a principal engineer at Amazon AWS. Before Amazon he was a distinguished Principal Engineer and a CUDA Fellow in NVIDIA. There he was best known for his work porting the AMBER molecular dynamics package to CUDA, attaining record-breaking performance in the process. In a previous life, Scott picked up a B.S. in biology from Siena College and a Ph.D. in biochemistry from the Pennsylvania State University.
