However, chatbot uses in education are still in their infancy. At the same time, college students must recurrently navigate challenging tasks, such as building graduation plans, learning about majors, retrieving information about courses and scheduling among others. Without timely and on-demand assistance and support, many students fail to raise these challenges. To address this problem, we present a smart virtual assistant for students that provides continuous instant support to student, staff and faculty communities.

Recent work applied knowledge of the true value of the optimum to the Gaussian Process probabilistic model typically used in Bayesian optimization. This, together with a new acquisition function called Confidence Bound Minimization, resulted in a Gaussian probabilistic posterior in which the predictions were no greater than the known maximum (and no less than for minimum). Our novel work applies Confidence Bound Minimization to Bayesian optimization with Student's-t Processes, a probabilistic alternative which addresses known weaknesses in Gaussian Processes - outliers' probability and the calculation of posterior covariance. The new model is applied to the problem of hyperparameter tuning for an XGBoost classifier. Experiments show superior regret minimization and predictive accuracy, versus the popular Expected Improvement acquisition function. Combining Confidence Bound Minimization with a transformed Student's-t Process probabilistic model and known optima produces superior training regret minimization and posterior predictions for the Six-Hump Camel(2D) and Levy(4D) benchmark problems, which do not fall below true minima.","PeriodicalId":437507,"journal":{"name":"Proceedings of the 3rd International Conference on Applications of Intelligent Systems","volume":"98 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-01-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124000359","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}

We believe that the semantics of each process should be taken into account to improve the captioning ' s accuracy. Furthermore, data processing, that is obtaining images from each process using several visual processing methods such as object detection should be important. We propose a captioning model where a sentence vector is embedded to consider the consistency of the recipe. From differences between generated recipes and the reference recipe, we can calculate recipe scores. We use three metrics that are used in previous studies to evaluate the image captioning model.

Concretely, four state-of-the-art algorithms are implemented and evaluated: Surge-Cast, Spiral, Surge-Spiral and a Probabilistic (Particle Filter-based) method. The experiments have been carried out with the gas dispersion simulator GADEN and the robotic tools offered by ROS (Robotic Operating System) under diverse, realistic environments that feature obstacles and turbulent airflows. Our study reveals, among other results, that Surge-Spiral out-performs Surge-Cast under turbulent wind conditions, and the particle filter approach becomes advantageous only when the assumption of a homogeneous wind holds. We believe that these findings can help the research community to decide on the most appropriate GSL method for a given application.

As for the cutting process, marker making plays an essential role. The exponentially increasing magnitude of possible size combinations due to a considerable larger size number in modern garment mass customization induce a larger workload of marker making. Compared with creating all the markers using commercial marker making software, the application of machine learning technologies for marker length estimation will benefit in both efficiency and accuracy. The results generated from the marker length estimation can be used for providing the input data of cutting order planning (COP) for lean garment production, and as well predicting the objective values of marker length for the guidance and evaluation of marker making. In this study, MLR and RBF NN were used to estimating marker lengths with various sizes (regarding mass production (MP) and mass customization (MC)). The results showed that MLR generally outperforms RBF NN. MLR is more appropriated for general markers containing articles of regular sizes and mixed markers. RBF NN can be potential for markers containing articles of irregular sizes or for group markers.","PeriodicalId":437507,"journal":{"name":"Proceedings of the 3rd International Conference on Applications of Intelligent Systems","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-01-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129085014","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}

Usually, the detection becomes possible in a stage where disease symptoms are already visible on the aerial part of the plant. However, once the disease has manifested in different parts of the plant, little can be done to salvage the situation. Here, we suggest that the use of visible and near infrared spectral information facilitates disease detection in cassava crops before symptoms can be seen by the human eye. To test this hypothesis, we grow cassava plants in a screen house where they are inoculated with disease viruses. We monitor the plants over time collecting both spectra and plant tissue for wet chemistry analysis. Our results demonstrate that suitably trained classifiers are indeed able to detect cassava diseases. Specifically, we consider Generalized Matrix Relevance Learning Vector Quantization (GMLVQ) applied to original spectra and, alternatively, in combination with dimension reduction by Principal Component Analysis (PCA). We show that successful detection is possible shortly after the infection can be confirmed by wet lab chemistry, several weeks before symptoms manifest on the plants.","PeriodicalId":437507,"journal":{"name":"Proceedings of the 3rd International Conference on Applications of Intelligent Systems","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-01-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115483517","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}
