    Abstract: An in-vehicle model training system includes a non-transitory computer readable medium for storing instructions; and a processor. The processor is configured to receive an input image; perform object detection, using an encoder, on the input image to identify at least one object, wherein the encoder includes an in-vehicle neural network (NN) model; and generate a first heatmap based on the determined distance to each identified object. The processor is configured to compare the first heatmap with a second heatmap generated by a trained neural network (NN); update the in-vehicle NN model based on differences between the first heatmap and the second heatmap; and determine whether a latency of the encoder satisfies a latency specification. The processor is configured to output the in-vehicle NN model in response to the latency satisfying the latency specification and the difference between the first heatmap and the second heatmap satisfying an accuracy specification.
