Damn. Terrible. I’m from LATAM and it’s very common to be kidnapped, specially in central america (bar costa rica and panama) and Colombia. They often ask for 1-2k, literally nothing but obviously here they were targeting them since they know they are luchos parents. Terrible but in hindsight (if it’s not drug related), they should be “fine” if you negotiate and pay them some money.
Kaggle is good for very basics. Their intro courses on python/pandas/numpy/ML are great. You can do all of them on like 3 days.
But if you want to go more in depth, go for the ML course in coursera. I took the OG one that I think it’s no longer there but tbh info is still very very relevant, only issue is that it was in matlab lol. I still redid everything on python.
I got a masters degree in DS after all of this and there was 1 other guy in the class who also took that ML coursera course and we were by far the most competent students in the class. Really good course.
After that tbh everyone was at base 0 when learning deep learning stuff and recommender stuff. You then start to learn that all of this AI is BS lol.
