Shagun Sodhani
PyDelhi Conference, 2017
About Me
- Developer with Analytics and Data Science team @Adobe.
- Works in Deep Learning applied to NLP.
- Teaching Assistant for Big Data course on Edx .
- Doing a Q&A session on Deep Learning with CommonLounge.
Agenda
- Introduction to Functional Programming
- Functional Programming in Python
- Functions in Action
Functional Programming
- Functions as the fundamental building blocks for any program.
- Focus on computing results rather than on performing actions.
- Describe what is to be done and not on how it is to be done.
- Leads to concise and safe code (less OffByOne mistakes)
Talk is cheap. Show me the code.
Linus Torvalds
Why Should I care
- Big Data and Distributed Computing
-
Deep Learning
- "weight tying" - using multiple copies of a neuron in different places is the neural network equivalent of using functions
Message from our BDFL
From http://python-history.blogspot.in/2009/04/origins-of-pythons-functional-features.html
The Missing Pieces
- Immutable Data Structures
- Pattern Matching
- Lazy Evaluation
- Tail Call Optimization
- Large Collection of List functions
Python does not promote functional programming even though it works fairly well.
