Weixian (Waylon) Li

PhD Student in AIAI at University of Edinburgh

I am currently a PhD student at the Artificial Intelligence Applications Institute at School of Informatics in University of Edinburgh, proud to be supervised by Prof. Tiejun Ma. I finished my Master by Research degree (2021-2022) at the Institute for Language, Cognition and Computation in University of Edinburgh with Prof. Shay Cohen and my bachelors degree at University of Edinburgh as well. I am mainly interested in applying deep learning and NLP method to financial area. More specifically:

  • Machine learning method for risk detection in financial market
  • Neural ranking models and retrieval
  • The development and application of pretrained language models (PLMs)
  • Domain adaptation of NLP models

Can LLM Have Spatial Intelligence?

Recently, our school celebrated the 60th anniversary of Computer Science & AI. To mark the occasion, the organizers invited Fernando Pereira to deliver a lecture on the connection between form and meaning in language. This subject has captivated the minds of linguists, computer scientists, and cognitive researchers for many years. During the lecture, Pereira presented a thought-provoking example. He posed the question: “Bob is sitting to the right of Alice, and Jack is to the left of Bob.

Contrastive Learning Note

Related reading: The Beginner’s Guide to Contrastive Learning SimCSE: Simple Contrastive Learning of Sentence Embeddings A Simple Framework for Contrastive Learning of Visual Representations Sentence-BERT: Sentence Embeddings using Siamese BERT-Networks Background Contrastive learning aims to learn effective representation by pulling semantically close neighbors together and pushing apart non-neighbors. Initially, contrastive learning was applied to computer vision tasks. As what it is shown in the figure below, we expect the model to learn the communities between two images that share the same label and the difference between a pair of images with different labels.
