PyTorch is the fastest growing Deep Learning framework and it is also used by Fast.ai in its MOOC, Deep Learning for Coders and its library. PyTorch is also very pythonic, meaning, it feels more natural to use it if you already are a Python developer.

Python for NLP: Introduction to the Pattern Library stackabuse.com

Published May 3, 2019 under Data Science

The Pattern library is a multipurpose library capable of handling the following tasks:

Natural Language Processing: Performing tasks such as tokenization, stemming, POS tagging, sentiment analysis, etc.
Data Mining: It contains APIs to mine data from sites like Twitter, Facebook, Wikipedia, etc.
Machine Learning: Contains machine learning models such as SVM, KNN, and perceptron, which can be used for classification, regression, and clustering tasks.

In this article, we will see the first two applications of the Pattern library from the above list. We will explore the use of the Pattern Library for NLP by performing tasks such as tokenization, stemming and sentiment analysis. We will also see how the Pattern library can be used for web mining.

Python at Netflix medium.com

Published May 3, 2019 under Python

As many of us prepare to go to PyCon, we wanted to share a sampling of how Python is used at Netflix. We use Python through the full content lifecycle, from deciding which content to fund all the way to operating the CDN that serves the final video to 148 million members. We use and contribute to many open-source Python packages, some of which are mentioned below. If any of this interests you, check out the jobs site or find us at PyCon. We have donated a few Netflix Originals posters to the PyLadies Auction and look forward to seeing you all there.
