Sparse representations for the cocktail party problem.
A striking feature of many sensory processing problems is that there appear to be many more neurons engaged in the internal representations of the signal than in its transduction. For example, humans have approximately 30,000 cochlear neurons, but at least 1000 times as many neurons in the auditory cortex. Such apparently redundant internal representations have sometimes been proposed as necess...
متن کاملThe cocktail party problem
Natural auditory environments, be they cocktail parties or rain forests, contain many things that concurrently make sounds. The cocktail party problem is the task of hearing a sound of interest, often a speech signal, in this sort of complex auditory setting (Figure 1). The problem is intrinsically quite difficult, and there has been longstanding interest in how humans manage to solve it. The p...
متن کاملThe Cocktail Party Problem
This review presents an overview of a challenging problem in auditory perception, the cocktail party phenomenon, the delineation of which goes back to a classic paper by Cherry in 1953. In this review, we address the following issues: (1) human auditory scene analysis, which is a general process carried out by the auditory system of a human listener; (2) insight into auditory perception, which ...
متن کاملSeparable representations for cocktail party processing
Perceptual parsing of a complex acoustic scene requires the following ingredients: (a) a representation that is “separable” in the sense that it allows patterns to be split into parts that belong to diverse sources, (b) rules and cues to guide the partition, and (c) processes that can make sense of the partitioned information in the event that the partition was imperfect and the partitioned inf...
متن کاملSchema learning for the cocktail party problem.
The cocktail party problem requires listeners to infer individual sound sources from mixtures of sound. The problem can be solved only by leveraging regularities in natural sound sources, but little is known about how such regularities are internalized. We explored whether listeners learn source "schemas"-the abstract structure shared by different occurrences of the same type of sound source-an...
