Witryna11 kwi 2024 · III. Calculating and Plotting ROC Curves. To calculate ROC curves, for each decision threshold, calculate the sensitivity (TPR) and 1-specificity (FPR). Plot the FPR (x-axis) against the TPR (y-axis) for each threshold. Example: Load a dataset, split it into training and testing sets, and train a classification model: WitrynaWhether measured in kg-cm, lb-in, or Nm, torque is the amount of load the motor or gear motor output shaft can overcome. On a dc motor / gear motor performance curve, torque is usually represented by the X-axis. The intersection of the speed line ( N) and the X-axis is the stall torque (T) point. This is where the motor produces its maximum ...
