Week of 9/28

Content: I have to admit that both lectures given this week were much clearer than the first time.  On Monday, Dr. Fridsma have a lecture on the big O, ontologies and the semantic web.  Dr. Fridsma gave an overview of the hype of semantic web and he told us why enumeration doesn't work. I really like how he explained that ontologies are engineering artifacts.

On Wednesday, Mr. Shuiwang lectured on machine learning.  Again, the second time was much clearer than the first time.  Shuiwang really emphasised that we know the difference between k-nearest neighbor and k-means. Where k-means is clustering.  K-means is usually used in image processing.  I really liked the online demos that he showed us. I found an interesting paper that talked about how k-means is used in gene expression data. http://www.biomedcentral.com.ezproxy1.lib.asu.edu/1471-2105/5/172
