چکیده

This paper presents the IPUS Integrated Process ing and Understanding of Signals architecture to address the traditional perceptual paradigm s shortcomings in complex environments It has two premises the search for correct interpretations of signal processing algorithms SPAs outputs re quires concurrent search for SPAs and control pa rameters appropriate for the environment and interaction between these search processes must be structured by a formal theory of how inappro priate SPA usage can distort SPA output We de scribe IPUS s key components discrepancy detec tion diagnosis reprocessing and di erential di agnosis and their instantiation in an acoustic in terpretation system This application along with another in the radar domain supports our claim that the IPUS paradigm is feasible and generic

Combining Approximate Front End Signal Processing with Selective Reprocessing in Auditory Perception

When dealing with signals from complex environments, where multiple time-dependent signal signatures can interfere with each other in stochastically unpredictable ways, traditional perceptual systems tend to fall back on a strategy of always performing nelydetailed, costly analysis of the signal with a comprehensive front end set of signal processing algorithms (SPAs), whether or not the curren...
