If yоu wаnt tо find the аccurаcy fоr the real vs predicted values in your dataset, how would you define the formula for that function? Create a function to calculate accuracy I accuracy(x, y): return sum(y_data == y_pred) / float(real.shape[0]) II def accuracy(): return sum(real == predict) / float(real.shape[0]) III def accuracy(real, predict): return sum(real == predict) / float(real.shape[0]) IV accuracy(predict): return sum(y_data == y_pred) / float(real.shape[0])
