Number 2. Data mining

Problem 1. (10) Describe the steps in knowledge discovery. For each step, please give a brief descript involved in data mining when viewed as a process of Problem 2. (10) Suppose a group of 12 students with the test scores listed as follows: 19, 71, 48, 63, 35, 85, 69, 81, 72, 88, 99, 95. Please smooth the data by "bin means" with the following partitioning methods: 2.1 Partition them into four bins by equal-frequency (equal-depth); then smooth them by means 2.2 Partition them into four bins by equal-width method; then smooth them by means
