WebMay 3, 2024 · Keep in mind that the loss is the negative loss likelihood of the targets under the predictions: A loss of 1.39 means ~25% likelihood for the targets, a loss of 2.35 means ~10% likelihood for the targets. This is very far from what you would expect from, say, a vanilla n-class classification problem, but the universe of alignments is rather ... Web2 Answers Sorted by: 1 I found the problem, it was dimensions problem, For R-CNN OCR using CTC layer, if you are detecting a sequence with length n, you should have an image with at least a width of (2*n-1). The more the better till you reach the best image/timesteps ratio to let the CTC layer able to recognize the letter correctly.
