Unsupervised Auto-Encoding Multiple-Object Tracker for Constraint-Consistent Combinatorial Problem

ICASSP 2020accepted

Multiple-object tracking (MOT) and classification are core technologies for processing moving point clouds in radar or lidar applications. For accurate object classification, the one-to-one association relationship between the model of each objects’ motion (trackers) and the observation sequences in…

A Two-class Hyper-spherical Autoencoder for Supervised Anomaly Detection

ICASSP 2019accepted

Supervised anomaly detection has been a tough problem due to its necessity of special handling of unseen anomalies. In this paper, we present a heuristic implementation of variational auto-encoder with von-Mises Fisher prior applied to a supervised anomaly detector. The closed latent space like sphe…

Complementary Set Variational Autoencoder for Supervised Anomaly Detection

ICASSP 2018accepted

Anomalies have broad patterns corresponding to their causes. In industry, anomalies are typically observed as equipment failures. Anomaly detection aims to detect such failures as anomalies. Although this is usually a binary classification task, the potential existence of unseen (unknown) failures m…
