  abstract  = {In this paper we describe the non-linear mappings we used with the Helsinki
	language identification method, HeLI, in the 4th edition of the Discriminating
	between Similar Languages (DSL) shared task, which was organized as part of the
	VarDial 2017 workshop. Our SUKI team participated on the closed track together
	with 10 other teams. Our system reached the 7th 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.},
