Hello, I was reading several books on recommender systems and in the literature the mAP (Mean Average Precision) metric is used a lot and I wanted to know how I can implement it, in the tutorials and in the API only TopK Accuracy appears, I was wondering if anyone has already implemented mAP@K, thanks.

It looks like you may use tfr.keras.metrics.MeanAveragePrecisionMetric.
