      We improve constraint-based data quality using trend dependency (TD) discovery, extending existing order dependencies (ODs) to allow variations and exceptions. Unlike ODs, TDs capture approximate functional mappings between ...

    • Preferential proximal policy optimization in reinforcement learning 

      Balasuntharam, Tamilselvan (2023-12-01)
      The Proximal Policy Optimization (PPO), a policy gradient method, excels in reinforcement learning with its ”surrogate” objective function and stochastic gradient ascent. However, PPO does not fully consider the significance ...

    • Unified processing of natural language and relational data
