No xxx_21cf file exists #1

i want to reprwoduce the ICASSP2022 article, so I need this file. I don't know how to modify it. By the way, I would like to ask if the implementation code of this article will be open source

Hi,

First of all, 21 CFs can be simulated with the existing repository by using the 1cf files instead. A simple way to do this is by modifying the connear_example.py file to keep 21 frequency channels out of the 201, by adding a line after line 113 that indexes the 3rd (frequency) dimension of the vbm variable from 0 to 200 with a step of 10 (make sure that the fullcf_simulation = 0 in the script). Otherwise, the build_connear function in the connear_functions.py file can be modified instead to have a CF selection integrated in the model definition, e.g. by adding the following lines between lines 103 and 104:

Ncf = 21 # number of CFs to keep
# Select cochlear CFs
cochlea_cfs = K.arange(0,201,int((201-1)/(Ncf-1)))
cochlea_out = Lambda(lambda x: tf.gather(x,cochlea_cfs,axis=2), name='freq_downsampling')(cochlea_out)

If you would still prefer to do this with the 21cf json files (and possibly have a parallel simulation of all channels with fullcf_simulation = 1), please provide me your e-mail and I can send these files to you. In case there is more interest for these pre-compiled 21-CF json files I can also add them to the repository.

Unfortunately the code of the ICASSP article has not been published online yet, but we plan on making the whole closed-loop framework publicly available as soon as possible.
