T cell maturation requires the rearrangement of clonotypic T cell receptors (TCR) capable of interacting with major histocompatibility complex (MHC) ligands to initiate positive and negative selection. Only 3-5% of thymocytes mature to join the peripheral T cell pool. To investigate the basis for this low success rate, we have measured the frequency of preselection thymocytes capable of respond...

We present a two stage blind source separation (BSS) algorithm for robot audition. The algorithm is based on a beamforming preprocessing and a BSS algorithm using a sparsity separation criterion. Before the BSS step, we filter the sensors outputs by beamforming filters to reduce the reverberation and the environmental noise. As we are in a robot audition context, the manifold of the sensor arra...

Current approaches to artificial attention are largely limited to the visual domain. Only some consider audition as a source of information at the same time. Yet, attention is not necessarily limited to a single modality or a mere agglomeration of several modalities in human perception. Cross-modal attention, and its manipulation by cross-modal cues, seems to play a vital role in asymmetric int...

A musically meaningful vocabulary is one of the keystones in building a computer audition system that can model the semantics of audio content. If a word in the vocabulary is not clearly represented by the underlying acoustic representation, the word can be considered noisy and should be removed from the vocabulary. This paper proposes an approach to construct a vocabulary of predictive semanti...

This workshop explored machine learning approaches to 3 topics: (1) finding structure in music (analysis, continuation, and completion of an unfinished piece), (2) modeling perception of time (extraction of musical meter, explanation of human data on timing), and (3) interpolation in timbre space. In recent years, NIPS has heard neural networks generate tunes and harmonize chorales. With a larg...

Microphone array techniques can improve the acoustic sensing performance on drones, compared to use of a single microphone. However, multichannel sound acquisition systems are not available in current commercial drone platforms. We present an embedded and recording system with eight microphones mounted quadcopter. The is developed based Bela, computing for audio processing. record from multiple...

We present a sceptical view of multimodal multistability--drawing most of our examples from the relation between audition and vision. We begin by summarizing some of the principal ways in which audio-visual binding takes place. We review the evidence that unambiguous stimulation in one modality may affect the perception of a multistable stimulus in another modality. Cross-modal influences of on...
