WebNov 28, 2016 · Kernel density estimation is a generalization of histogram density estimation. If you think about constructing a histogram with bin width h from your sample x ~, then a density estimate for x i ∈ x ~ is. f ^ ( x i) = k 2 h n, where k is the number of sample points in ( x i − h, x i + h). The estimator f ^ ( x i) can be rewritten as. Webtask, especially for CNN-based density estimation and crowd counting models.
