Prediction of Flight Delay

Weiqing Wang

Student Project Apr 2016

A website based on the website which provides flight prediction service based on the data gathered from these database weather information database, previous flight delay information database and calendar database. Using our website, customs can decide whether they should leave more time space between their travel plans (because the weather forecasts are only valid within a week in future, so we can only predict the probability of flight delay in the future one week). By choosing the date and flight number of their flight, the web will return a probability of the flight delay. Also, we may give customs some advice to arrange their agenda and selection of airline.

○ Design & Setup DB ○ Using linear regression to calculate the prediction. ○ Design & implement the website by myself. ○ Gather data from various source with my team mates.

Tech: PHP, MySQL

Data Mining

Feature selection is a process of selecting a subset of relevant features for use in model construction.In this project, three feature selection methods were applied: SVD/PCA, PCA & ICA and Autoencoder on the Alzheimer disease genes dataset to find out whether data selection works in the way we anticipated and the different between three methods.
