Ground contact timing detection

transfer learning improves ground contact timing detection in silico.

“Fine-tuning improved treadmill F1-scores up to n=10, while outdoor level scores plateaued at n=5.”

convolutional neural network improves ground contact timing detection in silico (F1-scores 0.9864 (treadmill), 0.9637 (outdoor level), 0.9538 (incline), 0.9029 (decline)).

“The CNN achieved the highest F1-scores (0.9864 - treadmill, 0.9637 - outdoor level, 0.9538 - incline, and 0.9029 - decline walking) and the lowest MAE.”
