Random Partitioning Forest for Point-Wise and Collective Anomaly Detection -- Application to Intrusion Detection
Pierre-Francois Marteau
In this paper, we propose DiFF-RF, an ensemble approach composed of random partitioning binary trees to detect point-wise and collective (as well as contextual) anomalies. Thanks t…
Sparsification of the Alignment Path Search Space in Dynamic Time Warping
Saeid Soheily-Khah, Pierre-François Marteau
Temporal data are naturally everywhere, especially in the digital era that sees the advent of big data and internet of things. One major challenge that arises during temporal data…
Hybrid Isolation Forest - Application to Intrusion Detection
Pierre-François Marteau, Saeid Soheily-Khah, Nicolas Béchet
From the identification of a drawback in the Isolation Forest (IF) algorithm that limits its use in the scope of anomaly detection, we propose two extensions that allow to firstly…
Times series averaging and denoising from a probabilistic perspective on time-elastic kernels
Pierre-François Marteau
In the light of regularized dynamic time warping kernels, this paper re-considers the concept of time elastic centroid for a setof time series. We derive a new algorithm based on a…
Times series averaging from a probabilistic interpretation of time-elastic kernel
Pierre-François Marteau
At the light of regularized dynamic time warping kernels, this paper reconsider the concept of time elastic centroid (TEC) for a set of time series. From this perspective, we show…
Down-Sampling coupled to Elastic Kernel Machines for Efficient Recognition of Isolated Gestures
Pierre-François Marteau, Sylvie Gibet, Clement Reverdy
In the field of gestural action recognition, many studies have focused on dimensionality reduction along the spatial axis, to reduce both the variability of gestural sequences expr…
