Complex app using ML:
CORRECTION: I said in ad portion of the video that my data could be stolen on unprotected WiFi. This is true but in the example I gave with LVworld which uses HTTPS it’s already encrypted. Sorry. Didn’t know that’s how it worked. I will correct that in any future ads with Nord.

Summary: I wanted to see if I could make an app that could decode baseball signs. Turns out we could and it was a great opportunity for me to learn more about Machine Learning and neural networks and artificial intelligence from my friend Jabril.

They are soft-

I make videos like this once a month all year long while supplies last:

  • Those balks! This is cool, but how does it compensate against human error? Signs are missed all the time. Sometimes you go when you shouldn't, other times you don't take off when you should. Some baserunners have an automatic green light regardless of the signs, and they will go on their best judgement. Is the code written to potentially adapt to the false positives or false negatives it will inevitably receive? Awesome videos btw!
