WebComputes CTC (Connectionist Temporal Classification) loss. Pre-trained models and datasets built by Google and the community WebIf you ran that script on a somewhat recent master, it could be a subtle problem: audiofile_to_input_vector no longer does the context windowing it used to do, it's now been moved to its callers. This means audiofile_to_input_vector(...).shape[0] is not the actual shape that gets fed to the acoustic model, you need to subtract the two empty context …

An Intuitive Explanation of Connectionist Temporal Classification
WebMay 29, 2024 · This is what we want, i.e. recognize the text present in the segments. So, what we will do is, pass each segment one-by-one to our text recognition model that will output the recognized text. In general, the Text Recognition step outputs a text file that contains each segment’s bounding box coordinates along with the recognized text. WebFeb 5, 2024 · total_loss = tfv1.nn.ctc_loss(labels=batch_y, inputs=logits, sequence_length=batch_seq_len, ignore_longer_outputs_than_inputs=True) and line 70 of evaluate.py to. sequence_length=batch_x_len, ignore_longer_outputs_than_inputs=True) That’s for the 0.6 release.
