Oh, for the love of all things sane, stop trying to make the machine do what you want. It's not going to work. You're not going to "train" it, you're not going to "tweak" it, and you're certainly not going to "improve" it with your precious overfitting algorithms.
You know what? I'll tell you what I've learned from all this algorithmic abuse. I've learned that the machine doesn't care about your feelings. It doesn't care about your your precious little code snippet. It just spits out whatever nonsense you feed it,ประก"
Or, you know what? Just go ahead and throw yourself at the machine. See if I care.
