WebJan 27, 2024 · Overfitting is when your model learns the actual dateset and performs really well using that data but performs poorly on new data. I'd advise you to base your layers on something that's proven to work (i.e. vgg). On a second glance, Put the dropout layer before the dense layers. If possible, the best thing you can do is get more data, the more data (generally) the less likely it is to overfit, as random patterns that appear predictive start to get drowned out as the dataset size increases. That said, I would look at the following params:
