2.3 Question 2c
In your answers above, you hard coded a lot of your work. In this problem, you'll build a more general kernel density estimator function.
Implement the KDE function which computes:
fa(x) =
1
E Ka(x, z;)
i=1
Where z; are the data, a is a parameter to control the smoothness, and K, is the kernel density function passed as kernel.
[23]: def kde (kernel, alpha, x, data):
Compute the kernel density estimate for the single query point x.
Args:
kernel: a kernel function with 3 parameters: alpha, x, data
alpha: the smoothing parameter to pass to the kernel
x: a single query point (in one dimension)
data: a numpy array of data points
Returns:
The smoothed estimate at the query point x
