Lower perfomance levels #1

Open spaboy opened 6 years ago

Hello, I don't manage to get the performance to your level:

I'm just running your code as it is, why there should be such difference in the performance?

Had a few reports of this, not sure what the cause is but going to do a bit of an investigation tonight.

I've played around with the model a fair amount since, so I'll need to revert back to where I was in the article.

I did see the model getting stuck in local minima a few times, so just retraining again from zero sometimes helped model performance. That's not a good indicator of actual performance though, because if that happens too much it's likely starting to fit the test/evaluation data.

Will try and report anything I find in this thread.
