Abstrakt

In this paper, we apply the variational information bottleneck
approach to end-to-end neural diarization with encoder-decoder
attractors (EEND-EDA). This allows us to investigate what in-
formation is essential for the model. EEND-EDA utilizes attrac-
tors, vector representations of speakers in a conversation. Our
analysis shows that, attractors do not necessarily have to con-
tain speaker characteristic information. On the other hand, giv-
ing the attractors more freedom to allow them to encode some
extra (possibly speaker-specific) information leads to small but
consistent diarization performance improvements. Despite ar-
chitectural differences in EEND systems, the notion of attrac-
tors and frame embeddings is common to most of them and
not specific to EEND-EDA. We believe that the main conclu-
sions of this work can apply to other variants of EEND. Thus,
we hope this paper will be a valuable contribution to guide the
community to make more informed decisions when designing new systems.
