Understand CLIP (Contrastive Language-Image Pre-Training) — Visual Models from NLP

by

CLIP introduces a model that enables zero shot learning for a new dataset (in addition to a new example) by using NLP to supervise pre-training. i.e., To identify an object, you can provide the name or description of a new object that the model has not seen before. Traditionally a computer vision model was trained … Read more

Distributed Machine Learning – Part 2 Architecture

by

Why Distributed Machine Learning? In the previous article we looked at how GPGPU, ASICS, AWS’s Inferentia, the new NVidia A100 chip and other advances in hardware have tremendously improved the performance of Machine Learning training and inference. However the increase in the volume of data and the increasing complexity of the machine learning models require … Read more
