Kx Machine Learning Notebooks - GitHub

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.

Classifier comparison — scikit-learn 1.0.2 documentation

Classifier comparison. ¶. A comparison of a several classifiers in scikit-learn on synthetic datasets. The point of this example is to illustrate the nature of decision boundaries of different classifiers. This should be taken with a grain of salt, as the intuition conveyed by these examples does not necessarily carry over to real datasets.
