Training the speaker and session subspaces is an integral problem in developing a joint factor analysis GMM speaker verification system. This work investigates and compares several alternative procedures for this task with a particular focus on training and testing with short utterances. Experiments show that better performance can be obtained when an independent rather than simultaneous optimi...

The representations and processes yielding the limited length and telegraphic style of language production early on in acquisition have received little attention in acquisitional modeling. In this paper, we present a model, starting with minimal linguistic representations, that incrementally builds up an inventory of increasingly long and abstract grammatical representations (form+meaning pairi...

This paper describes the SemEval-2013 Task 5: “Evaluating Phrasal Semantics”. Its first subtask is about computing the semantic similarity of words and compositional phrases of minimal length. The second one addresses deciding the compositionality of phrases in a given context. The paper discusses the importance and background of these subtasks and their structure. In succession, it introduces ...

It was recently argued that the geometric optics mean path length of rays inside a refractive object under Lambertian illumination is independent scattering strength medium [Savo et al., Science 358, 765 (2017)]. We here show it is, in fact, different case zero scattering. uncover and explain role trapped ray trajectories creating this unexpected discontinuity from to low This allows us derive ...

Previous studies have shown that text genres can be computationally distinguished by sophisticated computational and statistical methods. The current study adds to the previous body of work by incorporating phrasal verbs as a text genre identifier. Results indicate that phrasal verbs significantly distinguish between both the spoken/written and formal/informal dimensions, with considerably less...
