Temporal transformer CAN encoder with federated lightweight heads for anomaly detection

Modern vehicles rely on large numbers of Electronic Control Units (ECUs) that constantly exchange information over the Controller Area Network (CAN) bus. Due to the rapidity, structure, and repetition of this communication, even slight variations in timing, payload values, or message patterns can point to unusual activ...

Weight Importance Is Not Enough: Neural Expressiveness for Model Compression.

Neural Network Pruning has been established as driving force in the exploration of memory and energy efficient solutions with high throughput both during training and at test time. We propose Neural Expressiveness (NEXP), a new criterion for model compression that shifts the focus from weight importance to the capacity...
