WebFeb 3, 2024 · CNN always outputs the same values whatever the input image. So my problem is that I try a CNN to learn to classify images of skin cancer as benign or malignant. I feed the images, and whatever the image, I get the same outputs always. I tracked it down and it seems that after the first conv layer, the outputs are the same with every image. WebJan 10, 2024 · You can readily reuse the built-in metrics (or custom ones you wrote) in such training loops written from scratch. Here's the flow: Instantiate the metric at the start of the loop. Call metric.update_state () after each batch. Call metric.result () when you need to display the current value of the metric.
