Dear All,

Ravi volunteered to do the minutes this month:

---------------------------------------------

WHat is a Meetup?

A way to meet up - don't expect to understand details - know who is
doing what etc.

---------------------------------------------
Talk 1
Bringing back VanGogh - Krishna Sangeeth
@whitetruelearn

"Looks like my system crashed"
about_vanGogh:
	Starry Night
	cult painting that inspires many
	How to recreate this using technology?

VanGogh(content image + style image) -> stylized content image

Not New, But pretty new -> 2015 papers, Prisma App:
	Not just filters
	styles are learnt from style image
	features of content image are maintained
		
about_deep_neural_networks:
	based on human brain nueron
	perceptrons
	ex1: identifying a car using a deep NN
	ex2: identifying edges, curves, eye shape, nose shape etc = identify dog

how to get style and content right:
	content will be taken from close to end of content image
	style will be taken from close to start of style (first 4 layers)	

minimizing_loss_functions:
	optimize loss of content and loss of style

use the MS CoCo dataset but only 5K images

Use PyTorch for DNN

- Does  not work for pure white (needs research)

------------------------------------------------------


Talk2
Python Immigrants - Parthi

People who are born in late 90s etc are Digital Natives and older
people are Digital Immigrants
Similarly, speaker came to Python late, and hence is a Python Immigrant

4th wave is AI

What is MachineLearning?

Most popular language for ML is python	
Other websites, pygame, music, scientific, etc

Popular Libraries - numpy, scipy, matplotlib, pandas

About AI, ML and DL
Tools in DL - TF, PyTorch, theano, CNTK + Keras frontend

-------------------------------------------------------------

Talk3
Vishwanath

Product is more complex than service

the 'ec' library : to make command line parsing simpler:
	without arguments, a shell is opened, help is available on shell
	has an inbuilt debugger
	Click library on github has similar features and 4000 stars
	using/reading this code will give a good idea of Python decorators, a
\				very useful feature in Python

----------------------------------------------	
Lighting Talk1
Praveen

imgiko app that searches news and gives an image for sharing
ImageMagick port is Python Magick

Lighting Talk2
Shreyas

port something from a language you know
lpthw - it may be paid now
hacker rank - may be too complex
invent with python

pymongo to connect with Mongo
ETL - Python (pandas etc) is really good for these
Reddit has a page for learning python
Do small bits of automation
cheatsheets

David Beazly videos on concurrency etc.

---------------------------------------------

Anyone willing to send a PR to the website adding this in?

Best Regards,

Shrayas
