Today we finished discussing the the Parzen window method for estimating the probability density function at a point x of the feature space using samples. In particular, we discussed how, in the context of a decision problem, this technique boils down to a majority vote among the neighboring samples. However, it was pointed out that using different window volumes for different classes might improve the result of this voting procedure. Also, en interesting connection to the sampling theorem was pointed out by a student. | Today we finished discussing the the Parzen window method for estimating the probability density function at a point x of the feature space using samples.

Today we finished discussing the the Parzen window method for estimating the probability density function at a point x of the feature space using samples. In particular, we discussed how, in the context of a decision problem, this technique boils down to a majority vote among the neighboring samples. However, it was pointed out that using different window volumes for different classes might improve the result of this voting procedure. Also, en interesting connection to the sampling theorem was pointed out by a student.
Note that the second homework assignment is now posted. See you after Spring break!
