Data is the new oil and unstructured data, especially text, images and videos contain a wealth of information. However, due to the inherent complexity in processing and analyzing this data, people often refrain from spending extra time and effort in venturing out from structured datasets to analyze these unstructured sources of data, which can be a potential gold mine. Natural Language Processing (NLP) is all about leveraging tools, techniques, and algorithms to process and understand natural language-based unstructured data - text, speech and so on.

Being specialized in domains like computer vision and natural language processing is no longer a luxury but a necessity that is expected of any data scientist in today’s fast-paced world! With a hands-on and interactive approach, we will understand essential concepts in NLP along with the extensive case- studies and hands-on examples to master state-of-the-art tools, techniques, and frameworks for actually applying NLP to solve real-world problems. We leverage Python 3 and the latest and best state-of-the-art frameworks including NLTK, Gensim, SpaCy, Scikit-Learn, TextBlob, Keras and TensorFlow to showcase our examples. You will learn a fair bit of machine learning as well as deep learning in the context of NLP during this bootcamp.

In our journey in this field, we have struggled with various problems, faced many challenges, and learned various lessons over time. This workshop is our way of giving back a major chunk of the knowledge we’ve gained in the world of text analytics and natural language processing, where building a fancy word cloud from a bunch of text documents is not enough anymore. You might have had questions like ‘What is the right technique to solve a problem?’, ‘How does text summarization really work?’ and ‘Which are the best frameworks to solve multi-class text categorization?’ among many other questions! Based on our prior knowledge and learnings from publishing a couple of books in this domain, this workshop should help readers avoid some of the pressing issues in NLP and learn effective strategies to master NLP.

The intent of this workshop is to make you a hero in NLP so that you can start applying NLP to solve real-world problems. We start from zero and follow a comprehensive and structured approach to make you learn all the essentials in NLP. We will be covering the following aspects during the course of this workshop with hands-on examples and projects!

  • Basics of Natural Language and Python for NLP tasks
  • Text Processing and Wrangling
  • Text Understanding - POS, NER, Parsing
  • Text Representation - BOW, Embeddings, Contextual Embeddings
  • Text Similarity and Content Recommenders
  • Text Clustering
  • Topic Modeling
  • Text Summarization
  • Sentiment Analysis - Unsupervised & Supervised
  • Text Classification with Machine Learning and Deep Learning
  • Multi-class & Multi-Label Text Classification
  • Deep Transfer Learning and it's promise
  • Applying Deep Transfer Learning - Universal Sentence Encoders, ELMo and BERT for NLP tasks
  • Generative Deep Learning for NLP
  • Next Steps

With over 10 hands-on projects, the bootcamp will be packed with plenty of practical examples for you to go through, try out and practice and we will try to keep theory to a minimum considering the limited time we have and the amount of ground we want to cover. We hope at the end of this workshop you can take away some useful methodologies to apply for solving NLP problems in the future. We will be using Python to showcase all our examples.
