WordICA—emergence of linguistic representations for words by independent component analysis

T Honkela, A Hyvärinen, JJ Väyrynen - Natural Language …, 2010 - cambridge.org
We explore the use of independent component analysis (ICA) for the automatic extraction of
linguistic roles or features of words. The extraction is based on the unsupervised analysis of …

Learning Phonological Categories by Independent Component Analysis∗

B Calderone - Journal of Quantitative Linguistics, 2009 - Taylor & Francis
This work aims at discovering, in an unsupervised fashion, the nature of phonemes on the
basis of their distributional information within a representative corpus. We focus on some …
