The dataset was preprocessed and used to train five machine learning models: random forest, support vector machine, logistic regression, extreme gradient boosting and light gradient boosting. The goal was to use the best performing model to develop a web application capable of reliably predicting heart disease based on user-provided data. The extreme gradient boosting classifier provided the most reliable results with precision, recall and F1-score of 97%, 72%, and 83% respectively for Class 0 (no heart disease) and 21% (precision), 81% (recall) and 34% (F1-score) for Class 1 (heart disease). The model was further deployed as a web application.展开更多

Compared with the western learning culture,the Chinese learning culture is input-centered with two main characteristics:one is knowledge-centered and the other is teacher-centered. Under such learning cultural backgrounds,language teachers lay particular stress on the input of different kinds of knowledge and information while ignoring students 'necessary output. This kind of learning leads to "dumb English" for Chinese second-language learners. On the contrary,the western learning culture attaches great importance to develop students 'communicative competence,which is the ultimate aim of learning a language. The western language teachers utilize communicative approaches to improve students'communicative competence,which is absolutely practical in real-life situations. With closer contact with westerners,it is urgent for Chinese language teachers to blend the Chinese learning culture with the advantages of the western learning culture so as to develop students'communicative competence in English.展开更多

There is a large body of works on this topic in recent years, but the accuracy still needs to be improved due to challenges in appearance such as the high variability of shapes, lighting conditions, viewing angles and possible occlusions. To address these problems and limitations, we propose a novel approach in this paper for the eye center localization with a fully convolutional network(FCN),which is an end-to-end and pixels-to-pixels network and can locate the eye center accurately. The key idea is to apply the FCN from the object semantic segmentation task to the eye center localization task since the problem of eye center localization can be regarded as a special semantic segmentation problem. We adapt contemporary FCN into a shallow structure with a large kernel convolutional block and transfer their performance from semantic segmentation to the eye center localization task by fine-tuning.Extensive experiments show that the proposed method outperforms the state-of-the-art methods in both accuracy and reliability of eye center localization. The proposed method has achieved a large performance improvement on the most challenging database and it thus provides a promising solution to some challenging applications.展开更多
