recent years, there are many researches about the human activity recognition. In the most of these researches, the activity recognition experiments are performed with only a small number of subjects. Additionally, there is no public database of activity data or reference information about the suitable number of subjects. To overcome the situation, we have collected \u201dHASC2010corpus\u201d with more than 6000 activity data from more than 500 test subjects. In this paper, we report the result of the experiments on the effects of the number of subjects as a basic reference for the field of activity recognition research. By using the part of HASC2010corpus, we performed a large number of evaluations with the user-dependent / user-independent data, different number of the features, and the different number of subjects. In the case of using user-dependent data, decision tree classifiers showed the activity recognition results with an overall accuracy rate of 73targeted 13869 description subjects. The result of experiments shows the importance of the large number of subjects especially on the user-independent data. The result also suggests that by using more advanced features and more large number of subjects, the activity recognition rate might be improved.", "subitem_description_type": "Abstract"}]}, "item_10_identifier_60": {"attribute_name": "URI", "attribute_value_mlt": [{"subitem_identifier_type": "HDL", "subitem_identifier_uri": "http://hdl.handle.net/2237/15442"}]}, "item_10_publisher_32": {"attribute_name": "\u51fa\u7248\u8005", "attribute_value_mlt": [{"subitem_publisher": "\u4e00\u822c\u793e\u56e3\u6cd5\u4eba\u60c5\u5831\u51e6\u7406\u5b66\u4f1a"}]}, "item_10_rights_12": {"attribute_name": "\u6a29\u5229", "attribute_value_mlt": [{"subitem_rights": "\u3053\u3053\u306b\u63b2\u8f09\u3057\u305f\u8457\u4f5c\u7269\u306e\u5229\u7528\u306b\u95a2\u3059\u308b\u6ce8\u610f \u672c\u8457\u4f5c\u7269\u306e\u8457\u4f5c\u6a29\u306f\uff08\u793e\uff09\u60c5\u5831\u51e6\u7406\u5b66\u4f1a\u306b\u5e30\u5c5e\u3057\u307e\u3059\u3002\u672c\u8457\u4f5c\u7269\u306f\u8457\u4f5c\u6a29\u8005\u3067\u3042\u308b\u60c5\u5831\u51e6\u7406\u5b66\u4f1a\u306e\u8a31\u53ef\u306e\u3082\u3068\u306b\u63b2\u8f09\u3059\u308b\u3082\u306e\u3067\u3059\u3002\u3054\u5229\u7528\u306b\u5f53\u305f\u3063\u3066\u306f\u300c\u8457\u4f5c\u6a29\u6cd5\u300d\u306a\u3089\u3073\u306b\u300c\u60c5\u5831\u51e6\u7406\u5b66\u4f1a\u502b\u7406\u7db1\u9818\u300d\u306b\u5f93\u3046\u3053\u3068\u3092\u304a\u9858\u3044\u3044\u305f\u3057\u307e\u3059\u3002 Notice for the use of this material The copyright of this material is retained by the Information Processing Society of Japan (IPSJ).
