Codebook Capacity Governs Perceptual Quality Across Resolutions in Hierarchical Discrete Video Compression
Manikanta Kotthapalli, Banafsheh Rekabdar
Learned video codecs based on continuous latent representations typically require resolution-specific retraining or rate-distortion (RD) recalibration when scaling to new spatial r…
Entropy-Coded MS-VQ-VAE with Learned Priors for Ultra-Low Bitrate Video Compression
Manikanta Kotthapalli, Banafsheh Rekabdar
Learned video codecs based on continuous latent representations struggle to operate reliably below 0.1 bits per pixel~(bpp): without a differentiable rate signal, Lagrangian optimi…
LLM-Enhanced Reinforcement Learning for Time Series Anomaly Detection
Bahareh Golchin, Banafsheh Rekabdar, Danielle Justo
Detecting anomalies in time series data is crucial for finance, healthcare, sensor networks, and industrial monitoring applications. However, time series anomaly detection often su…
Dynamic Reward Scaling for Multivariate Time Series Anomaly Detection: A VAE-Enhanced Reinforcement Learning Approach
Bahareh Golchin, Banafsheh Rekabdar
Detecting anomalies in multivariate time series is essential for monitoring complex industrial systems, where high dimensionality, limited labeled data, and subtle dependencies bet…
