# Daniel Hsu | Codes

Some research codes hosted here:

- Hierarchical Sampling (software for cluster-adaptive sampling)
- Sample input: ocr-train
- The tree file is an array p[0,...,2n-2] of parent pointers (
*i.e.*, p[i] = parent of node i). The leaves are nodes 0,...,n-1, and the internal nodes are nodes n,...,2n-2. The parent of the root node should be -1. - The label file is an array y[0,...,n-1] of labels 0,...,K-1, where K is the number of classes.

- Estimators based on the method-of-moments (MATLAB codes)

Software hosted elsewhere:

- BOINC (software for volunteer computing)
- Vowpal Wabbit (fast online learning software)

Other stuff:

- Some Bkoos made using this perl script: (see bkoo.org for more information).
