Analysis mainly included possibilities of the moves a player will make and how the program should make a counter move. The Problem was taken up as a MinMax problem so that program writtern in that approach can make appropriate moves to maximize the possibilities of the system to win the game. He introduced a Naive and Hueristic function Approach and he also stated about Alpha Beta Pruning also as a approach for approaching gaming solutions. Watson and AlphaGo were Quoted as available AI solution when Questioned about extension of solution for multiplayers and next level of complex games like Chess.

He used watchMeDo to simultaneously create output data by running the python program.
Networking Tea Break
Rethinking Spreadsheets - Continued
Vijay Kumar continued his session post Networking Tea Break. He moved on with different data with array of data samples to show the changes in output. He had different view types support in his program. In his demo, he showed how one could create an pie chart, dough nut and bar chart with his program, which intern makes use of pygal to create charts.

With various answers from the audience he moved his presentation to point out the types of Lossy JPEG Compression available. He stressed on requirement of dimensional reduction with co-ordinate transformation and its requirement on data science.
