This paper investigates lossless coding of wideband speech by adding a lossless enhancement layer to the lossy baselayer produced by a standardised wideband speech coder. Both the ITU-T G.722 and G.722.2 speech coders are examined. Entropy results show that potential compression rates are dependent on the type and bit rate of the baselayer coder as well as the symbol size used by the lossless c...

| We investigate the learning of de-terministic nite-state automata (DFA's) with recurrent networks with a single input neu-ron, where each input symbol is represented as a temporal pattern and strings as sequences of temporal patterns. We empirically demonstrate that obvious temporal encodings can make learning very diicult or even impossible. Based on preliminary results, we formulate some hy...

In this paper, we derive an analytical framework for the performance evaluation of a recently proposed M-ary orthogonal scheme based on differential encoding/decoding of the Walsh/Hadamard chips prior/after spreading. This technique makes feasible nonpilot-assisted detection over fast fading environments such as the land mobile satellite (LMS) channel. Our results show that differential M-ary o...

In the context of the protein secondary structure prediction problem, we examine the performance of various neural network architectures commonly applied in the literature. Specifically,by applying the neural network paradigm, mappings between training vectors and their desired targets are constructed. The class membership of test data and associated measures of significance are then numericall...

Generalized pair weights of linear codes are generalizations minimum symbol-pair weights, which were introduced by Liu and Pan (2022) recently. can be used to characterize the ability protecting information in read wire-tap channels type II. In this paper, we introduce notion generalized <...

The switching method [4] is a scheme which combines two universal source coding algorithms. The two universal source coding algorithms both estimate the probability distribution of the source symbols, and the switching method allows an encoder to choose which of the two probability distributions it uses for every source symbol. The switching algorithm is an efficient weighting algorithm that us...
