vit-base-PICAI

This model is a fine-tuned version of google/vit-base-patch16-224 on the PICAI dataset. PI-CAI (Prostate Imaging: Cancer AI) is an all-new grand challenge, with over 10,000 carefully-curated prostate MRI exams to validate modern AI algorithms and estimate radiologists’ performance at csPCa detection and diagnosis. Key aspects of the study design have been established in conjunction with an international, multi-disciplinary scientific advisory board (16 experts in prostate AI, radiology and urology) ⁠—to unify and standardize present-day guidelines, and to ensure meaningful validation of prostate-AI towards clinical translation (Reinke et al., 2022). More can be found at the official Grand Channel Website: https://pi-cai.grand-challenge.org

It achieves the following results on the evaluation set:

• Loss: 0.6043
• Accuracy: 0.7371
• Roc Auc: 0.7059
