Multiple binary decision tree classifiers - ScienceDirect

The classifier branches left or right depending on whether the feature of a given object is absent (xi = O) or present (x,-- 1). Associated with every terminal node is a class assignment and a confidence measure. The binary tree classifier starts from the root node and traces a path through the tree until it reaches a terminal node.

This model can be seen as an extension of the polychotomous logistic regression model and is sim- ilar in structure and flavor to the projection pursuit regression models of Friedman and Stuetzle (1981). There is a large literature on such models (Ripley, 1996; Bishop, 1995), with many possibilities for fit-

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.

We show in this paper that they are indeed closely related and can be used to strengthen each other, specifically we have the following key insights: 1. The robustness of adversarial trained classifier can be

Classification using K-Nearest Neighbors in kdb+ - KX

The distance that the classifier uses is the minkowski distance with p=2 which is equivalent to the standard Euclidean metric. We apply the classifier to the dataset and store the predictions as kdb+ data. Using these predictions we can find the accuracy of the classifier using a q function that is defined in func.q.
