I'm sorry to bother you, can you give some usages (for example, the net prototxt file ) about CTC? I found that you changed the decode portion, is there any problems in the previous edition ? Thank you for any suggestion.

CTCGreedyDecoderLayer is used in the test units in test_ctc_decoder_layer.cpp, however it's no longer defined, because it was removed from the ctc_decoder_layer.cpp file. It still can be found in the ctc_decoder_layer.cpp.old.

Because of that, my "make test" fails.

I renamed it to CTCDecoderLayer. "make test" works now.

However my "make runtests" fails with the message

CTCLossLayerTest/1.TestGradient
src/caffe/test/test_ctc_loss_layer.cpp:569: Failure
Expected: (abs((-loss) - (loss_log_prob_0 + loss_log_prob_1) / 2)) <= (0.000001), actual: 2.15804e-06 vs 1e-06

Should I worry about it? It seems it's only a precision thing.
