Stream-based Active Learning with Verification Latency in Non-stationary Environments

1 code implementation14 Apr 2022 Andrea Castellani, Sebastian Schmitt, Barbara Hammer

Furthermore, we propose a drift-dependent dynamic budget strategy, which uses a variable distribution of the labelling budget over time, after a detected drift.

Task-Sensitive Concept Drift Detector with Constraint Embedding

1 code implementation16 Aug 2021 Andrea Castellani, Sebastian Schmitt, Barbara Hammer

In the proposed framework, the actual method to detect a change in the statistics of incoming data samples can be chosen freely.

Real-World Anomaly Detection by using Digital Twin Systems and Weakly-Supervised Learning

no code implementations12 Nov 2020 Andrea Castellani, Sebastian Schmitt, Stefano Squartini

The approaches make use of a Digital Twin to generate a training dataset which simulates the normal operation of the machinery, along with a small set of labeled anomalous measurement from the real machinery.
