摘要： A method of mapping a large number of items of contents each having meta-information to a low dimensional space so that the map of the contents reflects the meta-information. The method includes the steps of assigning a concept vector to each item of contents, adjusting the distance between two items of contents so that the closer the classification information of the two items of contents match, the more the distance is reduced, and assigning position information in the low dimensional space to each item of contents based on the adjusted distance.

摘要： At the coder side, bits of samples of each frame of an input digital signal are concatenated every digit common to the samples across each frame to generate equi-order bit sequences, which are output as packets. At the decoding side, the input equi-order sequences are arranged inversely to their arrangement at the coder side to reconstruct sample sequences. When a packet dropout occurs, a missing information compensating part 430 correct the reconstructed sample sequences in a manner to reduce an error between the spectral envelope of the reconstructed sample sequence concerned and a known spectral envelope.
