Text classificationHypergraph attention layerHyperGATLDALogistic regressionText classification plays a major role in research such as sentiment analysis, opinion mining, and customer feedback analysis. Text classification using hypergraph algorithms is effective in capturing the intricate relationships between ...
The code below shows how we start the training process. When you instantiate theLogisticRegressionmodule, you can vary the `solver`, the `penalty`, the `C` value and also specify how it should handle the multi-class classification problem (one-vs-all or multinomial). By default, aone-vs-...
重点:The classifier is trained using logistic regression classifier with features from Spark’s standard tokenizer and HashingTF 比较简单就是训练了一个逻辑回归的线性分类器,使用的特征是spark里的HashingTF,正样本是WebText, Wikiedia, and our web books corpus;负样本是unfiltered Common Crawl原始的Common C...
1)Text Classification Traditional text classification works mainly focus on three topics: feature engineering, feature selection and using different types of machine learning algorithms. For feature engineering, the most widely used feature is the bag-of-words feature. In addition, some more complex fe...
Two of the most popular algorithms for text classification are a Naive Bayes classifier and a logistic regression classifier (sometimes referred to as Maximum Entropy classifier or MaxEnt for short). These two algorithms are both efficient for high-dimensional data and have proven to be among the ...

We use Tencent news titles as our text classification dataset. A total of 8,826 titles of four categories (society, entertainment, healthcare, and military) are extracted. The lengths of titles range from 10 to 20 words. We train ℓ2-regularized logistic regression classifiers using the LIB...

A TensorFlow Tutorial: Email Classification(Feb 1, 2016 byJosh Meyer) It contains sample code for feeding customized training data set from csv files. It used a simple logistic regression classifier to classify Emails. A nice tutorial on WildML that uses TensorFlow:Implementing a CNN for Text Cl...
The classifier is trainable and not limited to logistic regression and can take on any form as long as it performs classification. Figure 4-12. Using the embeddings as our features, we train a logistic regression model on our training data. We will keep this step straightforward and use a ...
