NLP Hands-on Workshop and Competition

REGISTER

This is a hands-on workshop for total beginners in Natural Language Processing who are already proficient with python.

Potential audience: Whoever is interested in experimenting with this fascinating domain of NLP, whether you’re a pro data scientist with no experience in NLP or not a dev guy (PM, bizdev, …) but can code in Python.

We would cover text classification in python, using sklearn, spacy, nltk and pandas, via a challenge (and competition) over real data.

This event is hands-on, All attendees MUST bring:
============================
1. A laptop with python 3.6 installed (preferably anaconda for python3)
2. Download Data: http://goren.ml/pdnlp
3. Clone repository: https://github.com/urigoren/nlp_classification
