    KODERA Yuta , MIYAZAKI Takeru , KHANDAKER Md. Al-Amin , ALI Md. Arshad , KUSAKA Takuya , NOGAMI Yasuyuki , UEHARA Satoshi

    … Most of the properties for NTU sequence such as period, linear complexity, autocorrelation, and cross-correlation have been theoretically shown in our previous work. … However, the distribution of digit patterns, which is one of the most important features for security applications, has not been shown yet. …

    … Several recent studies have shown that total scores on depressive symptom measures in a general population approximate an exponential pattern except for the lower end of the distribution. … To confirm the reproducibility of such findings, we investigated the total score distribution and item responses of the Kessler Screening Scale for Psychological Distress (K6) in a nationally representative study. …

  • Visualizing the Distribution of a Large-Scale Pattern Set using Compressed Relative Neighborhood Graph  [in Japanese]

    Goto Masanori , Ishida Ryosuke , Uchida Seiichi

    … <p>The goal of this research is to understand the true distribution of character patterns. … If we can represent and analyze the distribution of a large-scale pattern set directly and understand its relationships deeply, it should be helpful for improving classifier for pattern recognition. …

  • EVALUATION OF HABITAT SUITABILITY OF AQUATIC INSECTS USING HYDROTHERMAL SIMULATION MODEL  [in Japanese]

    TAKASE Akihiko , NUKAZAWA Kei , KAZAMA So , WATANABE Kozo

    … We evaluated spatial variations of habitat suitability of nine aquatic insects in the Natori River basin, Northeast Japan quantitatively combining dual approaches of using Habitat Suitability Index (HSI) model analysis and hydrothermal simulation model. … We also developed a new index of the Weighted Usable Ratio (WUR) for evaluating the overall habitat suitability throughout the catchment for each species. …

  • Pattern Recognition with Gaussian Mixture Models of Marginal Distributions

    OMACHI Masako , OMACHI Shinichiro

    … Precise estimation of data distribution with a small number of sample patterns is an important and challenging problem in the field of statistical pattern recognition. … In this paper, we propose a novel method for estimating multimodal data distribution based on the Gaussian mixture model. …

  • A Classifier Based on Distance between Test Samples and Average Patterns of Categorical Nearest Neighbors

    Hotta Seiji , Kiyasu Senya , Miyahara Sueharu

    … The recognition rate of the typical nonparametric method "k-Nearest Neighbor rule (kNN)" is degraded when the dimensionality of feature vectors is large. … Another nonparametric method "linear subspace methods" cannot represent the local distribution of patterns, so recognition rates decrease when pattern distribution is not normal distribution. …
