Messages from Dr. Yong Zheng:
  • Call for PhD students: information about our PhD program, admission guidelines for domestic students and international students. The application deadline for the prospective PhD students starting in the upcoming Fall semester is Jan 31. Note that you need to mention me as your preferred PhD advisor in the application form and/or cover letter.
  • Dr. Zheng is looking for self-motivated PhD and Master students to conduct research in the area of data science and AI, paraticularly in recommender systems, user modeling and decision making, AI for Education and large language models (LLMs). Interested students please feel free to drop me an email with your CV, TOEFL/GRE, transcript (and I can not reply to every individual email).

About DMO

Decision making is a cognitive process that involves selecting a course of action or choice from among multiple alternatives. It's a fundamental aspect of human life and is present in various contexts, ranging from everyday situations to complex professional, personal, and strategic scenarios, such as resource allocations, risk management, strategic planning, cybersecurity, supply chain management, Web information systems (e.g., information retrieval and recommender systems), and so forth. Factors influencing decision making may include cognitive biases (mental shortcuts that can lead to errors in judgment), emotions, cultural and social influences, personal experiences, time constraints, and the availability of information.

Optimization, on the other hand, is a systematic process that aims to find the best possible solution based on specific criteria. It involves mathematical and computational techniques to minimize or maximize an objective function while adhering to a set of constraints. Optimization seeks to identify the globally optimal solution, which is the best solution achievable according to the defined criteria. Multiple optimization techniques have been proposed and applied in machine learning and AI, such as convex optimization, non-linear optimization, evolutionary algorithms, multi-objective optimization, game theroies, etc.

Welcome to the Center for Decision Making and Optimization (DMO) directed by Dr. Yong Zheng, where the future of informed decision-making meets the power of cutting-edge optimization techniques. In an increasingly complex and interconnected world, the ability to make informed choices and optimize outcomes is paramount. DMO is your gateway to a world of innovative research, advanced methodologies, and practical applications that empower individuals, organizations, and communities to navigate the complexities of decision-making with confidence and precision.

At DMO, we are dedicated to advancing the science and practice of decision-making and optimization across a wide range of disciplines and industries. Our multidisciplinary team of experts combines the latest advancements in mathematics, data science and AI, as well as domain-specific knowledge to tackle real-world challenges and create tangible solutions. Whether you're a business leader seeking to enhance operational efficiency, a researcher exploring new frontiers in optimization, or a policymaker aiming to make data-driven choices, DMO is your partner in unlocking the full potential of your decisions.
