TASMANIA ABALONE RING PREDICTION

Description

In this assignment we will apply machine learning techniques learned in the lectures and tutorials to analyse the population biology of abalone in Tasmania. In particular, we will predict the age of abalone from physical measurements. By observation, the age of abalone can be estimated by the number of rings which can be seen by a microscope. In this assignment you will predict the number of rings given other attributes.

Name	Data Type	Meas.	Description
----	---------	-----	-----------
sex	nominal		M, F, and I (infant)
length	continuous	mm	Longest shell measurement
diameter	continuous	mm	perpendicular to length
height	continuous	mm	with meat in shell
whole weight	continuous	grams	whole abalone
shucked weight	continuous	grams	weight of meat
viscera weight	continuous	grams	gut weight (after bleeding)
shell weight	continuous	grams	after being dried
edible	boolean.		True, and False
rings	integer		+1.5 gives the age in years

Task 1: Data Collection
Identify irrelevant information from the data and remove it to clean the data. Hint: Use Weka or Excel.

Task 2: Data Pre-processing
There are some missing values for height attribute and rings. Decide the way you handle this issue and explain why.
Hint: Use Weka or Excel.

Task 3: Data Transformation
We need to create a new attribute called volume from other attributes as: volume = length * diameter * height.
Normalise the data into [0-1] range.
Hint: Use excel or write program (if you know how to do it).

Task 4: Data Mining & Pattern Evaluation
Prepare your data from the to have:
- A training set of the first 2500 samples
- A validation set of the next 633 samples
- A test set of the last 1044 samples
Run 15 machine learning algorithms and report their accuracy on the validation set to a table.
Select the algorithm that give the highest accuracy in validation set and run the algorithm using the training set and test set. Report this result in test set.
There will be a table of top test result. Email me the results of test set at any time (screenshot of your results in Weka) to put your name to the rank.
Explain how the best algorithms work (in the report) Tips: How to improve performance?
- Handle the missing data issue effectively, use data normalisation, ury different techniques learned from lectures and select the ones that give top accuracy in validation

Task 5: Write a report
Write a report using the following template.
