Probabilistic constraints are those that should be satisfied at a certain probabilistic level and can consider the uncertainty of the parameters involved in the problem. Problems with such probabilistic constraints are generally difficult to solve. Therefore, based on previous research, we consider transforming a problem with probabilistic constraints into a 0–1 mixed integer programming problem under special conditions. Thereafter, we introduce the cutting plane method using a valid inequality of the feasible region.","PeriodicalId":188870,"journal":{"name":"2020 9th International Congress on Advanced Applied Informatics (IIAI-AAI)","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117183639","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, it is not possible to analyze the consumer’s purchasing process, such as what the consumer thinks and what he or she thinks, using data such as real store POS data and demographic attributes, which are the explanatory variables used in the conventional model. On EC sites, it is possible to obtain data on the process of a consumer’s purchase, in addition to data that can only be generated from the result of the consumer’s purchase, so it is possible to model various purchasing behaviors.The purpose of this study is to construct a consumer purchasing behavior model that takes into account consumer characteristics, which can be expressed from the time consumers spend on the site and their pre-purchase behavior, and to determine the importance of the features used in the model, so that marketing strategies can be developed from the model.","PeriodicalId":188870,"journal":{"name":"2020 9th International Congress on Advanced Applied Informatics (IIAI-AAI)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115710842","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The demographics of gender and age ranges were used for prediction. To identify the demographics of individuals, this study extracted effective features of mobile website access activities. We proposed a feature learning model from the raw inputs to solve the problem of classifying gender and age ranges using a deep convolutional neural network, which is an important but challenging task in digital marketing.

As an experiment for the evaluation of imitated motion images, we performed experiments with our collaborators. Then, we asked the collaborators for their opinions about real and imitated motion images. The results suggest that the imitated motion images are more effective. Because manual processing to produce imitated motion images is too much work, the existing technology, Pose2Pose, is used.

The proposed method is able to extract strategic phrases/words from the various types of enterprises' disclosure documents written in Japanese, through the process which consists of steps as follows: (1) stratified morphological analysis; (2) classification of strategic phrases/words; (3) elimination of inadequate strategic phrases by employing dependency analysis; also (4) XBRL parsing and new sentences extraction for formal annual securities reports, as optional step.

If we realize entailment generation, we can apply it to summarization that keeps semantics between an original text and a generated text. These days, neural networks are employed to construct modules that encode an original text and generate summarization. In natural language processing, sequence-to-sequence models, which realize sequential learning, are employed to develop machine translation. Moreover, attention mechanism is proposed to improve machine translation considering word alignment between a source language and a target language. In this paper, we applied an attention-based sequence-to-sequence model to an entailment generation task and confirmed the system realized entailment generation. The proposed method can capture important words in the input text and generate a frequent sentence, which is grammatically correct and semantically appropriate.
