2/2 Using an unsupervised alignment method (Gromov-Wasserstein Optimal Transport), we show the similarity structures between visual judgment and verbal description align on the coarse categorical level but lack precise one-on-one stimulus-level mapping.

1/2. Comparing representations of vision and language we find colorfulness, material name, and softness are the key features across participants. We also found that removing the “material names” from the text embeddings significantly decreased the correlation.

Analyzing the image representation of materials obtained from various pre-trained deep neural networks, we find that similarity structures in human visual judgments align more closely with those of the vision-language models than purely vision-based models.

How is vision and language related in human material perception? New paper from my lab is now out at.@PLOSCompBiol. We find verbal descriptions capture material appearance at a coarse level, but precise alignment is still lacking. @liao_oial @mswym8 .

Our first model, CTP-LLM, is a specialized version of GPT-3.5 Turbo, trained on our PhaseTransition (PT) Dataset. Our second model, BERT+RF, combines a clinical Bidirectional Encoder Representations from Transformers (BERT) with a Random Forest (RF).

Very happy to share that our paper "CTP-LLM: Clinical Trial Phase Transition Prediction Using Large Language Models" is accepted by IEEE BIBM . We predict #ClinicalTrials phase transition outcome from protocols using fine-tuned LLM.

Of course, the investigator has to be excellent. But it does need a ton of luck and support. How do we give this support in earlier days? From day one?.

Someone wrote us to encourage the nomination of a female scientist for YIA for @VSSMtg . To be impactful within 10 years of PHD. One needs 1) a supportive (optimal) family, 2) effective mentoring, and 3) supportive institutes. All posed extra challenges for female scientists.

Trying all day to upload a paper to biorxiv. The server doesn't work. Does anyone else also have this issue?.
