Sequential Outlier Detection Based on Incremental Decision Trees [PDF]
IEEE Transactions on Signal Processing, 2018 We introduce an online outlier detection algorithm to detect outliers in a sequentially observed data stream. For this purpose, we use a two-stage filtering and hedging approach. In the first stage, we construct a multimodal probability density function to model the normal samples. In the second stage, given a new observation, we label it as an anomaly

An Incremental Decision Tree for Mining Multilabel Data [PDF]
Applied Artificial Intelligence, 2015 Mining with multilabel data is a popular topic in data mining. When performing classification on multilabel data, existing methods using traditional classifiers, such as support vector machines SVMs, k-nearest neighbor k-NN, and decision trees, have relatively poor accuracy and efficiency. Motivated by this, we present a new algorithm adaptation method,

Incremental decision tree based on order statistics
The 2013 International Joint Conference on Neural Networks (IJCNN), 2013 New application domains generate data which are not persistent anymore but volatile: network management, web profile modeling... These data arrive quickly, massively and are visible just once. Thus they necessarily have to be learnt according to their arrival orders.

Active Learning Embedded in Incremental Decision Trees [PDF]
Brazilian Conference on Intelligent Systems, 2020 As technology evolves and electronic devices become widespread, the amount of data produced in the form of stream increases in enormous proportions. Data streams are an online source of data, meaning that it keeps producing data continuously. This creates the need for fast and reliable methods to analyse and extract information from these sources ...

PRESa2i: incremental decision trees for prediction of Adenosine to Inosine RNA editing sites [PDF]
F1000Research, 2020 RNA editing is a very crucial cellular process affecting protein encoding and is sometimes correlated with the cause of fatal diseases, such as cancer. Thus knowledge about RNA editing sites in a RNA sequence is very important. Adenosine to Inosine (A-to-I) is the most common of the RNA editing events.

Incremental Learning of Fuzzy Decision Trees for Streaming Data Classification [PDF]
Proceedings of the 2019 Conference of the International Fuzzy Systems Association and the European Society for Fuzzy Logic and Technology (EUSFLAT 2019), 2019 Data stream analysis is growing in popularity in the last years since several application domains require to continuously and quickly analyse data produced by sensors with the aim of, for instance, reacting immediately when problems arise, or detecting new trends.

Incremental Optimization Mechanism for Constructing a Decision Tree in Data Stream Mining [PDF]
Mathematical Problems in Engineering, 2013 Imperfect data stream leads to tree size explosion and detrimental accuracy problems. Overfitting problem and the imbalanced class distribution reduce the performance of the original decision-tree algorithm for stream mining. In this paper, we propose an incremental optimization mechanism to solve these problems.

Efficient incremental induction of decision trees [PDF]
Machine Learning, 1996 This paper proposes a method to improve ID5R, an incremental TDIDT algorithm. The new method evaluates the quality of attributes selected at the nodes of a decision tree and estimates a minimum number of steps for which these attributes are guaranteed such a selection. This results in reducing overheads during incremental learning.
