A method and system for compressing a Transformer model for autonomous vehicles (RVs) is disclosed. The method includes acquiring image sequence perception data from an RV's onboard camera, obtaining an input sequence matrix through word segmentation and tokenization; extracting features using an attention mechanism, deriving a fourth-order tensor kernel representation to construct its tensorized representation; decoupling spatial dependencies and feature channel mapping relationships using the Kronecker structure and linear homomorphic properties of the fourth-order tensor kernel; quantifying the upper bound of error using a Frobenius norm through Taylor expansion of the local linearization activation function; modeling the Transformer Block as a whole as a fourth-order tensor kernel, performing TT-SVD dual-kernel decomposition to achieve target position-related spatial attention and channel mapping while maintaining inference accuracy; and mapping the compressed dual-kernel back to physical space to construct a model suitable for embedded inference chips in RVs. This invention can reduce inference latency and meet the requirements for interpretable compression.
