ARSM Gradient Estimator for Supervised Learning to Rank
ICASSP, pp. 3157-3161, 2019.
We propose a new model for supervised learning to rank. In our model, the relevancy labels are are assumed to follow a categorical distribution whose probabilities are constructed based on a scoring function. We optimize the training objective with respect to the multivariate categorical variables with an unbiased and low-variance gradi...More
