In this paper, we propose a new method for task decomposition based on output parallelism, in order to find the appropriate architectures for large-scale real-world problems automatically and efficiently. By using this method, a problem can be divided flexibly into several sub-problems as chosen, each of which is composed of the whole input vector and a fraction of the output vector. Each module (for each subproblem) is responsible for producing a fraction of the output vector of the original problem. this way, the hidden structure for the original problem's output units is decoupled. these modules can be grown and trained in sequence or in parallel. Incorporated withthe constructive learning algorithm, our method does not require excessive computation and any prior knowledge concerning decomposition. the feasibility of output parallelism is analyzed and proved. Several benchmarks are implemented to test the validity of this method. their results show that this method can reduce computation time, increase learning speed, and improve generalization accuracy for both classification and regression problems.
We present an automatic approach for prefetching data for linked list data structures. the main idea is based on the observation that linked list elements are frequently allocated at constant distance from one another...

Kyushu Electric Power Co. Inc. has developed a watthour meter data recognition device, which enables data to be processed by a personal computer by optically recognizing images of attribute data (10 items including index and meter type) indicated on the meter plate. A prototype of the device is now undergoing demonstration tests. Since this device is capable of recognizing the data of a single meter in about 4 seconds, drafting of work plans and post-work documentation can be also automated, resulting in greater work efficiency and prevention of human error. Images are fed to the device using CCD cameras and are pre-processed or corrected before peripheral and mesh pattern matching of characters. this procedure has enabled a high recognition rate of characters of various sizes and fonts.
