It was, quite bluntly, an unmitigated disaster. Every NN began performing worse by … Continue reading Training data matters… and it’s hard to make

Unfortunately, I can now confirm that I've reached the limit of what I can train with my current method of generating training data. Some background: Neural Networks, as … Continue reading Getting better training data
