Nowadays, machine learning plays a vital role in software industry and is of utmost demand in day-to-day life activities. Machine learning has emerged as one of the popular technology for solving real-world applications as autonomous vehicle, speech recognition, image processing, natural language ...
《Thumbs up? Sentiment Classification using Machine Learning Techniques》笔记 这篇论文早就读过,现在重读一遍。 这是一篇2002年的论文,它的结论如下: 算法方面: SVM比最大熵和朴素贝叶斯好 特征方面: Bnigram并不比Unigram好 特征的presence比frequency好 词性影响不大 词的位置影响不大 读完。 读了也是白读,tal...
Many strategies, from simple automation to machine learning techniques, are being applied for a better return on investment. This conceptual blog will cover one of the most important concepts; classification in machine learning. We will start by defining what classification is in Machine Learning ...
Thumbs up? Sentiment Classification using Machine Learning Techniques TODO: No Tags: EMNLP Year: 2002 1. IDEA 解决电影评论的情感分类问题,作者将其简化成了二分类问题(正面和负面,但存在第三种情感:中立,本文忽略了中立的情况)。作者假设某些单词能够表示强烈的情感,之后生成这些单词来进行分类。 Figure 1是两...
52. Numerous informative techniques based on DGA to identify the emerging fault type have been stated. In this work, seven of the DGA approaches were explored: (i) the CIGRE approach, (ii) the Doernenburg ratio approach, (iii) the KG approach, (iv) the Nomograph approach, (v) the IEC...
AdaBoost [26] (short for “Adaptive Boosting”) is one of the most widely used and studied machine learning meta-algorithms. Boosting algorithms belong to a group of voting techniques [38], which produce classification decision as a linear combination of the output of other classifiers (also ca...
In this study, we examined the important and discriminative features, in order to recognize the various attacks by applying the Structural Sparse Logistic Regression (SSPLR) and Support Vector Machine (SVMs) methods. The SVMs are standard ML-based techniques, which provide the reasonable performance...
