  • ENTITY SELECTION AND RANKING USING DISTRIBUTION SAMPLING
    Publication number: 20240135240
    Abstract: Embodiments of the disclosed technologies include generating a reward score for an entity. A rate distribution is determined using the reward score. A sampled rate value is generated by sampling the rate distribution. A probability score is generated for a pair of the entity and a user using the sampled rate value. A probability distribution is determined using the probability score. A sampled probability value is generated by sampling the probability distribution. A machine learning model is trained using the sampled probability value.
    Type: Application
    Filed: October 19, 2022

    Inventors: Yafei Wei, Andrew O. Hatch, Keqing Liang, Liyan Fang, Ankan Saha
  • ENTITY SELECTION AND RANKING USING DISTRIBUTION SAMPLING
    Publication number: 20240134867
    Abstract: Embodiments of the disclosed technologies include generating a reward score for an entity. A rate distribution is determined using the reward score and a number of times the entity has been selected for ranking. A sampled rate value is generated by sampling the rate distribution. A probability score is generated for a pair of the entity and a user based on the sampled rate value. A probability distribution is determined using the probability score. A sampled probability value is generated by sampling the probability distribution. A machine learning model is trained using the sampled probability value.
