Machine Learning - What's the Biggest Challenge in Machine Learning?

machine learning has had an enormous impact on both industry and society, and it's all because of rectangles. What's changing now is there's things that aren't rectangles that we'd like to make predictions on,. So an example is like a molecule. Predicting molecules isn't as easy as just shoving them into something that looks like a rectangle. We took the bold manoeuvre of generalizing from squares torectangles. And that was quite remarkable jump to move to rectangles. Wat are some other examples. Machine learning on audios, typically done as spectrograms. We basically turned them into images, and then we kind of use ll the tricks from images. But i
