Natural Language Processing for Deep Learning

Machine learning is everywhere in today's NLP, but by and large machine learning amounts to numerical optimization of weights for human designed representations and features. The goal of deep learning is to explore how computers can take advantage of data to develop features and representations appropriate for complex interpretation tasks. I’ll be speaking on basic motivation, ideas, models and learning algorithms in deep learning for natural language processing. I’ll be talking about models which perform very well on various NLP tasks such as language modeling, POS tagging, named entity recognition, sentiment analysis and paraphrase detection, among others. The most attractive quality of these techniques is that they can perform well without any external hand-designed resources or time-intensive feature engineering. Despite these advantages, many researchers in NLP are not familiar with these methods. The goal of the talk will be to make the inner workings of these techniques transparent, intuitive and their results interpretable, rather than black boxes labeled "magic here". The first part of the talk will involve the basics of neural networks, neural word vectors, several simple models based on local windows and the math and algorithms of training via backpropagation and the second section will involve recursive neural networks which can learn structured tree outputs as well as vector representations for phrases and sentences.The principle goal, again, is to make these methods appear intuitive and interpretable rather than mathematically confusing. By this end of the talk, the audience members should have a clear understanding of how to build a deep learning system for word-, sentence- and document-level tasks.
