Online neuro-fuzzy CANFIS hidden-node teaching

Abstract: On-line first-order backpropagation (BP) has been widely employed for optimizing a multi-layer neural network and a fuzzy neural network. When BP is applied to a TSK fuzzy system, the interpretability of fuzzy rules may be lost. We describe a simple and effective remedy for the loss by casting the posed optimization problem into a general Bolza-type optimal-control mold so as to include stage costs on top of the terminal cost; this is what we called the (on-line) hidden-node teaching. Our on-line learning scheme turns out to be useful not only in optimizing a large model, a so-called CANFIS neuro-fuzzy modular network, but also in enhancing its generalization capacity. The fundamental concept is that each (local) expert network is supervised individually by hidden-node teaching for minimizing a stage cost while all local-expert modules are encouraged to cooperate in reducing the terminal cost simultaneously. Furthermore, we show how to construct a CANFIS modular network in order to alleviate the so-called curse of dimensionality that frequently hampers the design of fuzzy systems. In simulation, our concepts have been demonstrated in the letter recognition benchmark problem as well as in small regression and XOR-classification tasks.

Receiver with decision-directed equalizer

Abstract: A circuit is configured to receive and process a signal that includes in-phase and out-of-phase components that correspond to in-phase and out-of-phase components of a time sequence of symbols. A phase sensor in the circuit is configured to determine a phase value in accordance with an equalized version of the in-phase component of the signal and the in-phase component of the time sequence of symbols. The phase sensor is further configured to generate an approximation to the out-of-phase component of the signal in accordance with a Hilbert function of order k greater than 1. Terms in the approximation that correspond to future samples of the in-phase component of the signal are replaced with terms that correspond to past samples of an error that corresponds to a difference between samples of the in-phase component of the signal and an output from a detector.

Host interface for direct connection of an optical driver to an IDE/ATA data bus

Abstract: A compact disk drive controller to control the access of information from an optical compact disk (CD) digital data storage device by a host computer using an integrated drive electronics (IDE) data bus or an industry standard architecture (ISA) data bus is disclosed. A digital signal processor (DSP) interface to the drive electronics of the CD drive, a dynamic random access memory (DRAM) controller, an error correction code (ECC) data corrector, an error detection and correction (EDC) device employing cyclical redundancy checking techniques (EDC/CRC), and a host computer interface are described.

Activity normalization for video encoding
