BI-RADS, VinDr, class imbalance, model collapse, center loss
User attempted BI-RADS detection using cross-entropy loss, center loss, and class weights on VinDr dataset All three models collapsed to predicting BI-RADS 1 almost exclusively User seeks community input on whether loss function choice is the root cause
Emphasizes empirical observation and uncertainty; minimizes no aspect — no claims of novelty, impact, or resolution are made.
A researcher reported model collapse to BI-RADS 1 when training on VinDr due to class imbalance.
Model architectures, training duration, hardware constraints, evaluation metrics used
It leverages the credibility of community norms (transparency, humility, collaboration) to normalize failure without accountability; the tension lies between the severity of collapse (a systemic red flag) and its presentation as a minor tuning issue — no validation, no external benchmarks, no error analysis offered.
All three models collapsed to predicting BI-RADS 1 due to heavy class imbalance in VinDr.
all of them seem to collapse between birads 1 as the dataset (VinDr) im using is heavily unbalanced towards it
