A Machine Learning-Based Web Application for Heart Disease Prediction

This work leveraged predictive modeling techniques in machine learning (ML) to predict heart disease using a dataset sourced from the Center for Disease Control and Prevention in the US. 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.

Improvement of Attributed Scattering Center Extraction by Using SAR Super-Resolution Preprocessing

Synthetic aperture radar(SAR)is able to acquire high-resolution method using the active microwave imaging method.SAR images are widely used in target recognition,classification,and surface analysis,with extracted features.Attribute scattering center(ASC)is able to describe the image features for these tasks.However,sidelobe effects reduce the accuracy and reliability of the estimated ASC model parameters.This paper incorporates the SAR super-resolution into the ASC extraction to improve its performance.Both filter bank and subspace methods are demonstrated for preprocessing to supress the sidelobe.Based on the preprocessed data,a reinforcement based ASC method is used to get the parameters.The experimental results show that the super-resolution method can reduce noise and suppress sidelobe effect,which improve accuracy of the estimated ASC model parameters.

Exploring the Chinese and Western Language Learning Cultures

This paper examines the difference between the Chinese language learning culture and the western language learning culture. 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.

基于改进Center Loss函数的行人再辨识

通过改进距离度量函数,在开集测试协议的基础上,对行人再辨识相关问题进行研究,使测量的行人特征满足以下两点:类间最小距离较大和类内最大距离较小。目前还没有存在的算法能够满足这个条件。文中采用Center Loss函数和分类损失函数相结合,使网络在分类损失与Center Loss函数的联合监督下,可以学习出更具判别性的行人特征。其中,行人特征分辨性问题分类损失函数能很好地解决,但常规的Center Loss函数只能使类内最大距离较小,但未能解决类间最小距离较大的问题。因此对Center Loss函数进行改进,在Center Loss函数中加入类间距离变量,使类间中心最小距离较大。最后通过几组再辨识数据集的实验证明了提出的网络与改进Center Loss函数的优越性。

Accurate and Robust Eye Center Localization via Fully Convolutional Networks

Eye center localization is one of the most crucial and basic requirements for some human-computer interaction applications such as eye gaze estimation and eye tracking. 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.

改进Center-Net网络的自主喷涂机器人室内窗户检测

室内自主喷涂机器人可以实现室内墙面喷涂的自动化以此提升喷涂的效率,减少人力物力的投入。而基于计算机视觉的室内窗户检测算法则是该机器人的关键技术。对于室内窗户检测,由于环境光照、窗户形状和窗户透光属性的存在,传统方法无法得到较好的效果。针对此问题,设计一种基于深度学习的室内窗户检测算法。该算法主要对中心点网络(CenterNet)的特征提取网络进行修改,减少部分卷积操作,使用Ghost模块替换原始的卷积模块,降低特征冗余,并引入注意力机制,让网络尽可能表达重要信息。实验结果表明,改进的CenterNet在不损失网络精度的前提下,大幅度提高了网络的运算速度,使得该检测算法即使在机器人端的嵌入式系统上也可以达到实时检测的效果。
