Web22 jan. 2024 · Many machine learning models are designed around the assumption of balanced class distribution, and often learn simple rules (explicit or otherwise) like always predict the majority class, causing them to achieve an accuracy of 99 percent, although in practice performing no better than an unskilled majority class classifier. Web1) Your input shape on the first conv layer is using 3 (rbg) channels, but your data are greyscale (1 channel) 2) You don't need that many conv layers and filters, in fact I think a single layer, and a handful of small kernels will be fine. – photox Feb 14, 2024 at 12:04 1 Like @photox says, you do not need the conv layers.
