Air Reseach Information Infrastructure. OLAP – Data Modeling – Data Mining Algorithms. Laquo; Clustering Algorithm. Data Mining with Team Foundation Server. On October 18, 2006. The total worldwide OLAP market, including implementation services, was $4.9 billions in 2005 and estimated to be $6 billions in 2007. This represents a 400% increase over the past decade. Microsoft is typically chosen by smaller organizations, while SAP BW and MicroStrategy are much more likely to be found in the largest organiz...

Air Reseach Information Infrastructure. OLAP – Data Modeling – Data Mining Algorithms. Laquo; Data dredging. On October 16, 2006. After first defining the clusters, the algorithm calculates how well the clusters represent groupings of the points, and then tries to redefine the groupings to create clusters that better represent the data. The algorithm iterates through this process until it cannot improve the results more by redefining the clusters. By default, the shade represents the population of the cl...

Air Reseach Information Infrastructure. OLAP – Data Modeling – Data Mining Algorithms. On September 10, 2006. Or data fishing are terms one may use to criticize someone’s data mining efforts when it is felt the patterns or causal relationships discovered are unfounded. There have always been a considerable number of people who busy themselves examining the last thousand numbers which have appeared on a roulette wheel, in search of some repeating pattern. Sadly enough, they have usually found it. Most dat...

Air Reseach Information Infrastructure. OLAP – Data Modeling – Data Mining Algorithms. Laquo; Data Mining with Team Foundation Server. Welcome to the OLAP Terminologies. On November 20, 2006. Decision Rings: Making Decision Trees Visual and less Mathematical. A common step in quantifying a decision tree is to ask subjects to quantify their beliefs about an event using a probability wheel. This procedure implies that subjects do have geometrical intuitions about uncertainties. Consider the problem of deci...
