The common log file (CLF) format basically records the date and time of the transaction, the IP address of the remote host, the file that was requested, the size of the file in bytes, and the status of the request (for example, "404, file not found").
proposes using kernel extreme learning machine (KELM) to predict missing sonic DT logs when only common logs are available.
Here are some of the many opportunities to have more mathematics in the biology classroom: (a) using statistical tests to determine the probability that two data sets are really different or that differences are due to chance alone, (b) manipulating common logs for pH and decibels, (c) using other exponentials for dealing with large numbers such as evolutionary time, (d) using binomials (e.g., in Hardy-Weinberg equations for studying allele frequency shifts), (e) applying precision versus accuracy, (f) using proportional reasoning for population sampling, and (g) studying the entropy of an energy pyramid in an ecosystem.
In this paper, kernel-based extreme learning machine is used to predict missing sonic (DT) logs when only common logs (e.g., natural gamma ray--GR, bulk density--DEN, or deep resistivity--REID) are available.
