@Cricketracker Overall Csk has the best points table standings. The 265 points of 17 seasons only.
If we fill the remaining two seasons points using CSK's average (265/17 = ~15 points per season), the total would be 295 points.

This list is unfair for CSK. Same goes for RR.

Your ML model is only as good as the data you feed it.

Very few know where companies, researchers and AI labs actually source data from.

I listed 10 platforms where professionals actually get real-world data 👇

@Vikashq_ Since AI itself is evolving at super fast pace, I don't think any programming language except Python would be able to keep up.

One asks vaguely.
The other follows a proper system.
