I had worked on an online machine learning method[0] last year that assumes priming effect (similar to the effect you and the GP describe, i.e., the timing effect) and tries to exploit it. With respect to infinite scrolling/ranking, I have also worked on a simplified model (unfortunately does not capture spacing of likes but captures fatigue based on relevancy) and and algorithm to work with it.[1] [0] https://arxiv.org/abs/2006.10356 https://arxiv.org/abs/2006.10356: Learning by Repetition: Stochastic Multi-armed Bandits under Priming Effect [1] https://arxiv.org/abs/1901.07734 https://arxiv.org/abs/1901.07734: Thompson Sampling for a Fatigue-aware Online Recommendation System
