Web13.6.3 Cosine-Weighted Hemisphere Sampling. As we will see in Section 13.10, it is often useful to sample from a distribution that has a shape similar to that of the integrand being estimated.For example, because the scattering equation weights the product of the BSDF and the incident radiance with a cosine term, it is useful to have a method that generates … Web5 de jul. de 2008 · This work presents a practical and statistically consistent scheme for actively learning binary classifiers under general loss functions that uses importance …
