核心概念
此研究提出了一種基於兩階段概念的新方法,利用預先訓練好的視覺語言模型和大型語言模型,在無需額外訓練的情況下,提供基於概念的皮膚病變診斷,並提高可解釋性和信任度。
統計資料
PH2 數據集包含黑色素細胞病變的皮膚鏡圖像,包括“黑色素瘤”和兩種“痣”。
Derm7pt 包含超過 2,000 張臨床和皮膚鏡圖像。
HAM10000 包含 10,015 張不同身體部位的各種皮膚病變的皮膚鏡圖像。
引述
“The main challenges hindering the adoption of deep learning-based systems in clinical settings are the scarcity of annotated data and the lack of interpretability and trust in these systems.”
“Concept Bottleneck Models (CBMs) offer inherent interpretability by constraining the final disease prediction on a set of human-understandable concepts.”
“By simulating the two stages of a CBM, we utilize a pretrained Vision Language Model (VLM) to automatically predict clinical concepts, and a Large Language Model (LLM) to generate disease diagnoses based on the predicted concepts.”
