The methodology presented in the paper is based on repeatedly building Isolation Forest models on datasets from which individual attributes are excluded. In our research, we used the SHAP (SHapley Additive exPlanations) method which comes from game theory and is used to determine the impact of ...

This research delves into real-time anomaly detection in enormous-scope sensor networks, employing Isolation Forest, One-Class SVM, Local Outlier Factor, and Recursive Partitioning algorithms. The review features Isolation Forest as a champion entertainer, accomplishing an accuracy of 0.92 and a review...
Isolation Forest isolates anomalies in the data points instead of profiling normal data points. As anomalies data points mostly have a lot shorter tree paths than the normal data points, trees in the isolation forest does not need to have a large depth so a smaller max_depth can be used res...
In this paper we propose a methodology for unsupervised anomaly detection and diagnosis using historical OES data that addresses both the dimensionality and correlation challenges. This consists of a dimensionality reduction pre-processing step, anomaly detection using the Isolation Forest algorithm (Liu et...
The solution to this problem for many forest-dwelling species, may be colonization of alternative habitats, such as parks, orchards or rural avenues, located in the highly fragmented agricultural landscape. Our main objective was to determine the effect of both habitat quality parameters and ...
In this paper are investigated five unsupervised Machine Learning (ML) methods for PV plants' faults detection. The tested methods include Isolation Forest (IF), one-Class Support Vector Machines, Local Outlier Factors, Deep Learning Autoencoders, Gaussian Mixtures Models (GMM). Dealing with ...
The Madeiran archipelago consists of Madeira itself, Porto Santo and the Deserta islands. On Madeira, the forest arid the coastal floral associations are so different that their faunas are effectively isolated and have undergone largely independent development. There are different faunal associations on...
