Targeted collapse regularized autoencoder for anomaly detection: black hole at the center

no code implementations22 Jun 2023 Amin Ghafourian, Huanyi Shui, Devesh Upadhyay, Rajesh Gupta, Dimitar Filev, Iman Soltani Bozchalooi

In practice, however, it is observed that autoencoders can generalize beyond the normal class and achieve a small reconstruction error on some of the anomalous samples.

Towards Diverse and Coherent Augmentation for Time-Series Forecasting

no code implementations24 Mar 2023 Xiyuan Zhang, Ranak Roy Chowdhury, Jingbo Shang, Rajesh Gupta, Dezhi Hong

We note that augmentation designed for forecasting requires diversity as well as coherence with the original temporal dynamics.

Sensei: Self-Supervised Sensor Name Segmentation

1 code implementation Findings (ACL) 2021 Jiaman Wu, Dezhi Hong, Rajesh Gupta, Jingbo Shang

A sensor name, typically an alphanumeric string, encodes the key context (e. g., function and location) of a sensor needed for deploying smart building applications.

SeNsER: Learning Cross-Building Sensor Metadata Tagger

1 code implementation Findings of the Association for Computational Linguistics 2020 Yang Jiao, Jiacheng Li, Jiaman Wu, Dezhi Hong, Rajesh Gupta, Jingbo Shang

Sensor metadata tagging, akin to the named entity recognition task, provides key contextual information (e. g., measurement type and location) about sensors for running smart building applications.

Scaling Configuration of Energy Harvesting Sensors with Reinforcement Learning

no code implementations27 Nov 2018 Francesco Fraternali, Bharathan Balaji, Rajesh Gupta

We show that it is possible to reduce the number of RL policies by using a single policy for nodes that share similar lighting conditions.

Local Binary Pattern Networks

no code implementations19 Mar 2018 Jeng-Hau Lin, Yunfan Yang, Rajesh Gupta, Zhuowen Tu

In this paper, we tackle the problem us- ing a strategy different from the existing literature by proposing local binary pattern networks or LBPNet, that is able to learn and perform binary operations in an end-to-end fashion.
