This study demonstrates the ecacy of neural implementations of multistage and tree-search quantization. For xed branching ratio we have seen that the tree-search quantizer consistently outperforms the multi-stage structure, though at considerable resource cost. For networks with equal neural resource, the multistage architecture returns signicantly lower mse than the at and tree-search architec...

A case-control comparison of immunologic and psychological parameters in the multiple chemical sensitivity syndrome. This letter is prompted by Rall's editorial on media and science in the January issue of EHP (102:10). Rall implies that bad reporting is being conducted concerning dioxin, CFCs, and asbestos. Rall concludes by assuming that he is correct in assigning a high level of risk to each...

We presented in some detail our natural language information retrieval system consisting of an advanced NLP module and a `pure' statistical core engine. While many problems remain to be resolved, including the question of adequacy of term-based representation of document content, we attempted to demonstrate that the architecture described here is nonetheless viable. In particular , we demonstra...

Finally, some preliminary results from simulations are reported. The experiments employed the Markov channel models as configured in 4.1 and the evaluation module of 3.2 with α = 15%, applied to a transmissions of the well-known Foreman sequence in QCIF format at 9.6 kb/s. The video codec was the H.263 TMN [3], i.e., without error correction and concealment techniques. Fig. 7 shows the above in...

in correcting the garbled letter sequence from a known list of 5,000 city names. The most likely city name is computed by using a discrete HMM, given the recognized letter sequence. The third line refers to the fully integrated approach in which the city name list is expressed as a grammar written in GNF. It offers the possibility to check the efficiency of our integrated approach on a language...

[Pram90] A. Pramanick, S. Reddy, " On the design of path delay fault testable combinational circuits " , Proc. at time t. After the application of the next clock the contents of the even flip-flops of the LFSR are shifted into the odd ones (see Figure 10b) producing the second vector. The content of the first output is derived by XORing the outputs of some flip-flops including the last one. Not...

negative effect is naturally more significant in the more complex domain. The graph for the simple domain crosses the 0 line earlier than the complex domain. That means that learning starts to be useful with weight greater than 0.6 for the simple domain and 0.7 for the complex domain. As we relax the optimality requirement more significantly (with a W = 0.8), macro usage in the more complex dom...

, we can get a measure of the relative importance of certain parameters with respect to the output function. For instance, it is clear that the length of transistor M6 has a bigger effect on the sensitivity of speed to Ld than other parameters. Table 2 summarizes the best choices of each parameter for every performance. The last column is a selection of parameter settings that represent a few o...

In this paper we have presented the NPen ++ system, a neural recognizer for writer dependent and writer independent on-line cursive handwriting recognition. This system combines a robust input representation, which preserves the dynamic writing information, with a neural network integrating recognition and segmentation in a single framework. This architecture has been shown to be well suited fo...
