| Feb 1, 2019 at 13:56 | comment | added | Lio Elbammalf | Could you try retraining on a different set of 99 - randomly selecting - and looking for similarities in participants the model doesn't predict well for? It could be that the model does well predicting for participants who had their data collected on a particular day, particular room etc etc. I don't know what those differences are but sometimes it helps to start with considering external factors you haven't yet taken into account. | |
