We propose a novel approach for one-class classification problems where a logical formula is used to estimate the region that covers all examples. A formula is viewed as a model that represents a region and is approximated with respect to its hierarchical local densities. The approximation is done quite efficiently via direct manipulations of a binary decision diagram that is a compressed representation...
This paper estimates quality of experience (QoE), i.e., user-level QoS from MAC-level QoS for audio-video transmission over an IEEE 802.11e EDCA wireless LAN. The MAC-level QoS in this case has already been studied extensively; however, it may not provide exact information on QoE, which we can obtain by the estimation. We first examine MAC-level QoS by simulation in the case where wireless stations...
Abstract This study aims to evaluate the validity and reliability of a Japanese version of the Arthritis Impact Measurement Scales, version 2 (AIMS2) for patients with rheumatoid arthritis (RA). The Japanese version of the AIMS2 questionnaire was administered to 1643 patients with classical or definite RA at 11 hospitals nationwide in Japan. Reliability was assessed by a testretest procedure, 4 weeks...
