This paper presents a method for automatic classification of environmental sounds into three major categories, namely bird sounds, human speech and noise. Three various algorithms are used to classify the sounds individually and their efficiencies are compared. The classification algorithms are based on cyclostationary features, Mel Frequency Cepstral Coefficients (MFCC) and our proposed algorithm...
Data security in a highly confidential large network is of paramount importance. Confidential data networks belonging to secret agencies and government organizations are common targets for data exfiltration. This has become a growing concern in such networks. Present day intrusion detection and prevention systems and firewalls cannot possibly prevent an insider exfiltrating vital data for ulterior...
We developed a modern numerical approach to the multivariate linear discrimination of Fisher from 1936 based upon singular value decomposition that is sufficiently stable to permit widespread application to spatiotemporal neuronal patterns. We demonstrate this approach on an old problem in neuroscience—whether seizures have distinct dynamical states as they evolve with time. A practical result was...
