ADVERSARIAL-ROBUST VECTOR QUANTIZED VARIATIONAL AUTOENCODER WITH SECURE LATENT SPACE FOR TIME-SERIES DATA

Abstract: a system and methods for implementing adversarial-robust compression and reconstruction using a vector quantized variational autoencoder (vq-vae) with secure latent space management. the system provides comprehensive protection against adversarial attacks through multi-channel threat detection, adaptive defensive parameters, and coordinated response mechanisms. input data is continuously monitored for potential threats, and defensive parameters are dynamically adjusted based on detected threat levels. the system implements bounded constraints and hierarchical projections to maintain latent space security while preserving compression efficiency. multi-stage reconstruction with progressive validation ensures reliable data recovery even under adversarial conditions. the system coordinates defensive responses across all compression and reconstruction processes, implementing various recovery mechanisms when security violations are detected. this approach enables robust compression and reconstruction of time-series data while maintaining protection against various forms of adversarial manipulation.
