simply by integrating along this basically we're just integrating along the tangent manifold part yes yes yeah and you could also you know just integrate over the entire space but then you lose some of the nice some of the nice properties did that help oh yeah and we could talk we can talk about after so the nice thing about this measure is that you can develop a marker a Monte Carlo approximation in terms of the training data points the X ends that are your training data point and the affine mapping parameter so it's
