The Kx NLP library can be used to answer a variety of questions about unstructured text and can therefore be used to preprocess text data in preparation for model training. Input text data, in the form of emails, tweets, articles or novels, can be transformed to vectors, dictionaries and symbols which can be handled very effectively by q.

Read MoreThe linear classification model is basically the same as the linear regression, but the target value is generally 1/0 dichotomous or discrete (Fig. 2.14), rather than outputting continuous values like regression. A linear classifier is an algorithm that separates …

Read More(Added 3 hours ago) Classifier chains (see ClassifierChain) are a way of combining a number of binary classifiers into a single multi-label model that is capable of exploiting correlations among targets. For a multi-label classification problem with N classes, N binary classifiers are assigned an integer between 0 and N-1.

Read MoreTagging more data to improve the classifier. The amount of data that you need for your classifier strongly depends on your particular use case, that is, the complexity of the problem and the number of tags you want to use within your classifier.. For example, it's not the same to train a classifier for sentiment analysis for tweets than training a model to identify the …
