As I'm just starting out, I think that I probably do something wrong..\nAt the first few epochs my loss is around 7. - 8. and accuracy is about 0.5 and those values never really improve.\nI'm not training with the additional data yet.\nI'm hoping that you could push me in the right direction?</p>",
