I’ve just submitted a new article to CodeProject, entitled "Handwriting Recognition using Kernel Discriminant Analysis". The article is a demonstration of handwritten digit recognition using Non-linear Discriminant Analysis with Kernels and using the Optical Recognition of Handwritten Digits data set from the University of California’s Machine Learning Repository.
The Code Project is a free repository of source code, tutorials and development resources. It is also home of a large and ever-growing community of software developers, architects and other technology professionals. It has fairly active forums, and is a reasonably good resource for resolving difficult software development issues.
