Attention-based vector quantized variational autoencoder for anomaly detection by using orthogonal subspace constraints

This paper introduces a new framework that uses a vector quantized variational autoencoder (VQVAE) enhanced by orthogonal subspace constraints (OSC) and pyramid criss-cross attention (PCCA). The framework was designed for anomaly detection in industrial product image datasets. Previous studies on mo...
