compact cnn how to obtain the dominant tags ? #32

Closed emmanuelbernieri closed 6 years ago

emmanuelbernieri commented 7 years ago

Hello again,

i've implemented the compact-cnn neural network however the output is a vector of 0 & 1 corresponding to inditifed taggs. Is it possible like in the CRNN to only have the dominant taggs like :

[('jazz', '0.444'), ('instrumental', '0.151'), ('folk', '0.103'), ('Hip-Hop', '0.103'), ('ambient', '0.077')]

Kind regards

Emmanuel

Really? I'm using Sigmoid as an activation function in the output layer, so it can't be like that if you're using the result as it is.

Does the music file format has an importance ? I cannot analyse mp3 so I convert them into wav and then I analyse.

after preprocessing the audio input with librosa it gives me an output like that:

[[[ 0. 0. 0. ..., 0.04826343 0.05228163 0.05081845]]]

Yes, whatever the file format is, it should be decoded which you do when you're using librosa.load.

even when I use the 1100103.clip.npy. The output of the prediction is still [0.....1]

model

emmanuelbernieri commented 7 years ago

I'm using

python 3.6 Keras 2.0.6 Tensorflow 1.3.0 Theano 0.9.0 Librosa 0.5.1

Please check out the keras version (and possibly others) as readme. I think the theano version was either 0.7 or 0.8 at the moment.

I'll try to set up exactly the same config as yours tomorrow and let you know the result

emmanuelbernieri commented 7 years ago

I didn't succeed in reproducing your result.

Do you have a docker for a demo ?

Kind regards

No I don’t.
