06 Jun 2013 K2 algorithm for learning DAG structure in Bayesian network This is the code of Cooper's K2 algorithm proposed in 1992, quick and convenient for using. Author: Guangdi Li

Dear Pedro:

I advise you to use software Graphviz, or draw in photoshop, or powerpoint.

Regarding the mapping of nodes in matlab, it takes extra effort to make it beautiful. You can refer to my paper: Bielza, C., Li, G. & LarraƱaga, P. (2011). Multi-Dimensional Classification with Bayesian Networks. International Journal of Approximate Reasoning, 52, 705-727.

thanks for your interest!

02 Dec 2011 Maximum Weight Spanning tree (Undirected) Chu-Liu-Edmonds Algorithm for learning "Undirected Maximum Weight Spanning tree" is proposed here. Author: Guangdi Li

I would like to help, but I don't have time, sorry.

I guess that's the task of your project, no?

20 Sep 2011 Fisher's exact test with n x m contingency table Do you have problem with Fisher's exact test where the contingency table is more than 2*2? Author: Guangdi Li

Thanks for report, Karin.

The infinite problem is solved and a new version based on matlab-R is provided(for those who are familiar with fisher test in R).

05 Sep 2011 Discretization algorithms: Class-Attribute Contingency Coefficient To discrete continuous data, CACC is a promising discretization scheme proposed in 2008 Author: Guangdi Li

You can use the returned variable: DiscretizationSet, to discrete new continuous data. DiscretizationSet is a matrix containing K row and F columns, each column represent one feature, following your input feature data, then the cutoff is saved in corresponding column for your new discretization.
hope it is clear :)

22 Jul 2014 Fisher's Exact Test for beginners. For beginners, who loves Fisher's Exact Test but hates the theory behind. Author: Guangdi Li Luke

strongly not recommended to use this software as it returns incorrect p values.

07 Jul 2014 Amino acid conservation.zip Analysis of amino acid conservation using conservation index Author: Guangdi Li James

Fig. 1B should be removed. It is misleading because your code does not produce it.

16 May 2014 Mutual Information In probability theory and information theory Code for marginally and conditional mutual information in probability and information theory Author: Guangdi Li mei

I guess, this is a silly question, anyway, I do not understand what is the LGObj which CMI asks as its input together with variables. Can you please make it clear for me?

Thanks in advance.

21 Apr 2014 Fisher's exact test with n x m contingency table Do you have problem with Fisher's exact test where the contingency table is more than 2*2? Author: Guangdi Li Jian Zhang

Please address the p-value issue as questioned in earlier posts, otherwise this test is useless.

17 Feb 2014 Maximum Weight Spanning tree (Undirected) Chu-Liu-Edmonds Algorithm for learning "Undirected Maximum Weight Spanning tree" is proposed here. Author: Guangdi Li Yaser

Doesn't work when there are isolated nodes in the graph.
