Computationally efficient damped Capon and APES spectral estimation

In this paper, we introduce computationally efficient imple- mentations of the data-dependent non-parametric damped Capon (dCapon) and APES (dAPES) spectral estimators. These estimators form two-dimensional frequency represen- tations over both frequency and damping, and have been shown to enable an efficient separation of closely spaced spectral lines with different line widths. The proposed impl

Representations, symbols, icons, concepts... and why there are no mental representations

One of the key claims I have defended previously is that longstanding arguments over whether concepts are either (mental) representations or(non-representational) abilities gets its premises fundamentally wrong: concepts must be both. When one reflects on them – when one considers one’s concepts as concepts – they just are representations; but when one possesses and employs them non-reflectively t

Some reasons for studying gesture and second language acquisition (Hommage à Adam Kendon).

This paper outlines some reasons for why gestures are relevant to the study of SLA. First, given cross-cultural and cross-linguistic gestural repertoires, gestures can be treated as part of what learners can acquire in a target language. Gestures can therefore be studied as a developing system in their own right both in L2 production and comprehension. Second, because of the close link between ges
