deep learning models, such as data preprocessing, model selection, model validation, hyperparameter tuning, and performance metrics. Besides, the chapter covers different deep learning models for a variety of applications, such as classification, localization, and segmentation. The chapter aims to make...
Materials processing is a critical subset of manufacturing which is benefitting by implementing machine learning to create knowledge from the data mined/collected and gain a deeper understanding of manufacturing processes. In this study, we focus on aluminum high-pressure die-casting (HPDC) process,...

《Applying Deep Learning to Answer Selection: A Study And an Open Task》文章理解小结 本篇论文是2015年的IBM watson团队的。 论文地址: 这是一篇关于QA问题的一篇论文: 相关论文讲解1、https://www.jianshu.com/p/48024e9f7bb22、http://www.52nlp.cn/qa%E9%97%AE%E7%AD%94%E7%B3%BB%E7%BB%9F...
(2) 在预处理过程输出的数据上提取特征,进行features extraction及feature selection的操作,比如进行HOG计算,之后进行特征降维等; (3) 在获得的features vectors(instances)之上,使用各种model进行学习,训练,最终完成具体任务,如Classification,Recognition等 这里面通常把通常把(1)和(2)统称起来叫做Feature Learning。需要...
Deep learning model在Anomaly Detection问题中也已经有明显的效果; Shallow model往往学习不到复杂的特征模式,或者需要对特征进行繁琐(或是先验)的特征工程步骤处理,这种two-phase而不是end-to-end的形式往往学习不到局部最优/全局最优的结果。 3. 异常检测问题中的难点: normal samples中的差异性可能是非常大的,甚...
