Day 9 – Transformers & Attention Mechanisms Explained

Leave a Comment / Deep Learning /

Introduction Transformers have revolutionized Natural Language Processing (NLP) and many other AI domains. Unlike traditional RNNs or LSTMs, Transformers use attention mechanisms to process entire sequences simultaneously, enabling faster training and better handling of long-range dependencies. At CuriosityTech.in, learners in Nagpur explore Transformers through hands-on projects, such as building chatbots, text summarizers, and recommendation engines. […]
