In the era where the waves of artificial intelligence (AI) and machine learning are sweeping across the globe, academic exchanges have become increasingly frequent and in-depth. Top-tier academic conferences have emerged as the key engines driving the development of this field. Among them, the annual conference of the Association for Computational Linguistics (ACL), a premier event in the field of Natural Language Processing (NLP), has captivated the attention of scholars worldwide, serving as a vital platform for showcasing cutting-edge research achievements and sparking intellectual collisions.

Recently, ACL 2025 successfully concluded in Vienna, Austria, from July 27 to August 1, 2025. This conference, a gathering of the world’s top scholars, witnessed the NLP field’s vigorous development. The competition was fierce, with over 8,000 submissions and only about 20% accepted. In this challenging environment, Wendi Cui from Intuit Inc. and his team stood out with their paper titled “Automatic Prompt Optimization via Heuristic Search: A Survey”.

This paper innovatively and thoroughly explores automatic prompt optimization through heuristic-based search algorithms, enabling the automated refinement of instructions. It systematically categorizes and analyzes existing methods across five dimensions: optimization space, target, criteria, operators, and iterative algorithms, thereby offering researchers a clear analytical framework to understand the field, while experimentally demonstrating its potential to enhance information retrieval systems via optimized query reformulation, and inspiring practical research on Large Language Models (LLMs).

However, this wasn’t Wendi Cui’s first highlight at top-tier conferences. In 2024, his paper “Divide-Conquer-Reasoning for Consistency Evaluation and Automatic Improvement of Large Language Models” was accepted by EMNLP. He proposed the DCR automation framework, combining divide-and-conquer and reasoning to evaluate and improve LLM-generated text quality and consistency. This innovative achievement offers a brand-new perspective for addressing the critical challenge of evaluating and enhancing the quality of text generated by LLMs, holding significant implications for advancing the NLP field.

By publishing groundbreaking papers at two consecutive premier NLP conferences, Wendi Cui has fully demonstrated his profound academic expertise and sustained innovative capabilities in the NLP field. His research not only keeps pace with the cutting-edge developments in the field but also dares to break away from tradition, providing practical solutions to information retrieval challenges. This has earned him widespread recognition and acclaim in the international academic community.

Wendi Cui’s outstanding achievements in academia are inseparable from his solid professional foundation and profound educational background. He holds a master’s degree in Artificial Intelligence and Innovation from Carnegie Mellon University (CMU), a globally renowned institution at the forefront of AI. CMU is celebrated for its exceptional faculty, state-of-the-art research facilities, and a rich academic atmosphere. There, Wendi Cui received systematic and rigorous professional training, studied under renowned scholars in the field, and participated in numerous challenging research projects, laying a solid foundation for his future academic research and innovative practices.

While focusing on academic research, Wendi Cui has always adhered to the principle of applying theoretical knowledge to practical technologies and actively engaged in the wave of technological innovation. With his keen insights and outstanding technical skills, he has developed a series of software copyrights and patents of great value, spanning multiple cutting-edge fields.

Among them, the “Natural Language Interaction Chatbot System” has brought a more natural and seamless human-computer interaction experience, driving the upgrade and development of applications such as intelligent customer service and virtual assistants. The “Multimodal Search Engine Core Technology System” has broken through the limitations of traditional search engines by enabling the integrated retrieval of text, images, audio, and other multimodal information, providing users with a more comprehensive and accurate way to access information. Additionally, “Boosted Latent Dirichlet Allocation With Predefined Topic Clusters and Repelling Force” represents an innovative breakthrough in topic modeling for large-scale text data, offering a more powerful tool for text mining, information classification, and other fields.

These technological achievements not only hold significant academic value but also demonstrate immense potential in practical applications. They are gradually being applied in various sectors, including finance and education, providing strong support for technological innovation and business development in related industries and generating substantial economic and social benefits.

Wendi Cui has emerged as an AI field star, thanks to his remarkable academic feats, sustained innovation, and technology development contributions. His stellar academic performances and rich tech outcomes have unlocked new potentials in information retrieval based on NLP and inspired researchers. Expect him to keep exploring AI, driving industry and social progress. Under his lead, more breakthroughs are likely, paving the way for a smarter future.
