# train the network using triplet loss
# see pyannote.audio.embedding.approaches for more details
approach:
name: TripletLoss
params:
metric: cosine # embeddings are optimized for cosine metric
clamp: positive # triplet loss variant
margin: 0.2 # triplet loss margin
duration: 2 # sequence duration
sampling: all # triplet sampling strategy
per_fold: 40 # number of speakers per fold
per_label: 3 # number of sequences per speaker
# use precomputed features (see feature extraction tutorial)
feature_extraction:
name: Precomputed
params:
root_dir: tutorials/feature-extraction
# use the TristouNet architecture.
# see pyannote.audio.embedding.models for more details
architecture:
name: TristouNet
params:
rnn: LSTM
recurrent: [16]
bidirectional: True
pooling: sum
linear: [16, 16]
# use cyclic learning rate scheduler
