The prototype learning framework aims to generate prototypes of audio singnals for a respiratory sound classification task (normal/crackle/wheeze/both).

The experiments are based on the ICBHI 2017 challenge database.

1. For the basic CNN model without generating prototypes:

sh run.sh

2. For CNN models with generating prototypes:

sh run_prototype.sh

Note:The variant of 'PROTO_FORM' can be adapted for different prototype learning approaches:

Prototype-1D: PROTO_FORM='vector1d'

Prototype-2D-EleSim-Van: PROTO_FORM='vector2d'

Prototype-2D-EleSim-Att: PROTO_FORM='vector2d_att'

Prototype-2D-AvgSim-Van: PROTO_FORM='vector2d_avgp'

Prototype-2D-MaxSim-Van: PROTO_FORM='vector2d_maxp'

Prototype-2D-MaxSim-Att: PROTO_FORM='vector2d_maxp_att'
