Abstract

Providing an evaluation machine comprising a discriminator network (D), a generator network (G), and an encoder network (E), it is an object of the present application to generate a signal (160) indicating anomalous vehicle scenario. The object is achieved by a method comprising calibration steps:a) storing noise signals and output signals of the generator network (G) in a replay buffer (260);b) receiving previous generator output signals (G_rb) and previous noise signals (z_rb) from the replay buffer (260);c) updating the discriminator network (D), the encoder network (E), and the generator network (G) using:- training signals (x) from vehicle sensors (120) and an output signals of the encoder network (E);- the previous generator output signals (G_rb) and the previous noise signals (Z_rb);- noise signals (z) and an output signals of the generator network (G);the method further comprising detection steps:d) generating an anomaly score from an output signal of the encoder network (E), an output signal of the generator network (G), and/or an output signal of the discriminator network (D), wherein an input signal to the encoder network (E) includes data from vehicle sensors (120);e) comparing the anomaly score with a pre-set threshold; andf) generating a signal (160) indicating anomalous scenario depending on the comparison, preferably if the anomaly score is above the pre-set threshold.
