1. This document discusses the history and recent developments in natural language processing and deep learning. It covers seminal NLP papers from the 1990s through 2000s and the rise of neural network approaches for NLP from 2003 onward. 2. Recent years have seen increased research and investment in deep learning, with many large companies establishing AI labs in 2012-2014 to focus on neural network techniques. 3. The document outlines some popular deep learning architectures for NLP tasks, including neural language models, word2vec, sequence-to-sequence learning, and memory networks. It also introduces the Chainer deep learning framework for Python.
