Senior🎓
Top SchoolYuta Saito is a PhD candidate in Computer Science at Cornell University researching counterfactual learning under Prof. Thorsten Joachims, focused on leveraging biased logged bandit feedback and interactive human behavior data to enable safer, more reliable decision making in real-world systems. With a background in Industrial Engineering and Economics from Tokyo Institute of Technology and eight years of industry and research experience, he blends rigorous causal inference with practical machine learning. Based in Ithaca, he explores methods to correct for real-world biases in datasets and translate counterfactual insights into deployable policies. Notably, his work targets the often-overlooked interplay between human feedback loops and algorithmic recommendations, aiming to improve both effectiveness and trustworthiness in interactive systems.
