Evaluating HeLI with Non-Linear Mappings
Tommi Jauhiainen, Krister Lindén, Heidi Jauhiainen · 2017
In this paper we describe the non-linear mappings we used with the Helsinki language identification method, HeLI, in the 4 th edition of the Discriminating between Similar Languages (DSL) shared task, which was organized as part of the Var-Dial 2017 workshop.Our SUKI team participated in the closed track together with 10 other teams.Our system reached the 7 th position in the track.We describe the HeLI method and the non-linear mappings in mathematical notation.The HeLI method uses a probabilistic model with character n-grams and word-based backoff.We also describe our trials using the non-linear mappings instead of relative frequencies and we present statistics about the back-off function of the HeLI method.
