Let's data mining together: December 2008

http://oufcomputing.blogspot.com/2008_12_01_archive.html

Let's data mining together. Omar U. Florez. Tuesday, December 2, 2008. Research] Distribution of spatiotemporal events to describe movement in video. Since I am taking Applied Spatial Statistics, I am starting to consider a statistical approach to model the presence of events in video. Rather than describing the method of Laptev, this approach will be a mechanisim to formally discuss in the paper the existence of gradients in human movement. I have also defined the "conflictive" spatiotemporal gradients ...

Let's data mining together: What is going on with P = NP?

http://oufcomputing.blogspot.com/2010/08/what-is-going-on-with-p-np.html

Let's data mining together. Omar U. Florez. Monday, August 30, 2010. What is going on with P = NP? Is a major unsolved problem in Computer Science. Regarding the recent attempt to solve it this problem by Vinay Deolalikar. August 6, 2010). In this post we will briefly review what is this about P = NP. And it looks like the recent Vinay. S proof is not correct. Moreover, it has some issues that make it hard to fix. What P and NP means? Given a problem, first we want to discover. Is always included in NP.

Let's data mining together. Omar U. Florez. Thursday, June 17, 2010. Top 10 Data Mining Algorithms (in 2006). A colleague took my attention to the top-10 algorithms that have influenced greatly on the development and practice of science. And engineering in the 20th century, according to. As expected, the list is kinda historical trying to cover quite wide areas used in Engineering. It is also nice to find Francis Sullivan. Please, read their top-10 document. The Monte Carlo method. This is the story.

Let's data mining together: Hello, again.

http://oufcomputing.blogspot.com/2010/06/hello.html

Let's data mining together. Omar U. Florez. Tuesday, June 8, 2010. Hello many things happened from the time I wrote my last post. My major professor moved to a different university and I changed a little bit my research orientation. It is still data mining. But more related now to data bases. That change is to be expected since now I am in a data bases research group. However, I am still mixing up computer vision. Omar U. Florez. Subscribe to: Post Comments (Atom). Omar U. Florez. Omar U.
