Experiment Design & Result Analysis

Assignment 4 – Experiment Design & Result Analysis

Tasks:

1.    Collect your data for experiment

a.     Identify the available data sources for collection.

b. Select the most appropriate data source(s) and start data collection. You are asked to record the data sources that you have found, brief description of the available data using the following sample table:

c.     Store the collected data in appropriate file format. You need to save the collected raw data, and keep a copy at all times.

i.    Create a folder called “raw data” to store the collected raw data

ii.   Record your data collection using the following sample table:

2.    Design and implement experiments

a.     Adopt data pre-processing. Not all the collected raw data are available as direct input of your methodology.

b. Feature selection or dimension reduction. You may need to select some of data features or data records from the entire data collection, not to use all the collected data. In other case, you may need to reduce the dimensionality of the collected data to simplify the data processing in the later stages. You need to save the result data set into a new file. You are asked to record these works using the following sample table.

c.  Design your experiment based on the proposed methodology. The main purpose of experiments is to prove that your methodology can provide expected outcomes. You can follow the experiments that you have read from literatures or any other ways that is suitable for your case. Your experiments procedure need to be detailed recorded, including instruction steps, input data, expected output, potential problems and other related issues. When state the procedure of experiment, you can use extra table, figure, chart, diagram to provide better description.

d. To implement your experiment, normally you need to use software/tools or write your own program. Record your experiment results for each run as the references of the following analysis task.

3.    Result analysis and summary

a.  What are the expected results that you want to obtained from the experiment? You need to have a rough idea of what you may have in advance; you cannot wait until the experiment is done.

b.  Plan your result analysis by thinking of what result you may have first. Write a summary of why you expected to have that results, how they can be linked to your research problems.

4.    Write up your experiment and result analysis chapter.

a.  Provide an outline of your experiment and result analysis chapter, including up to four levels of subsections. Only need to list the chapter titles (level 1), section titles (level 2), subsection titles (level 3), and sub-subsection titles (level 4).
