Data visualisation techniques in data mining

1. Parallel coordinates
2. Scatter plots
3. Trent figures
4. Facial features expression

Where are they applied?

1. To speed up product design process
2. To analyze conformation of chemical structure
3. To measure quality of life (e.g. to visualise how different factors affect the degree of happiness)

Teamwork

1. Teamwork size should be about 3,4 or 5 people (i.e. too many people make it hard to coordinate)
2. Teamwork should be diversity in ages (i.e. to generate several perspectives)

K-nearest neighbour classfier, k-fold cross validation, leave-one-out

1. K-nearest neighbour classfier
Base on k training instances to classify a new instance into the majority class. The distance between the new instance and each of k training instances is often computed by Euclidean distance.

2. K-fold cross validation
The idea of k-fold cross validation is to try to estimate the true predictive accuracy of a classifier. It is often carried out for a small training dataset. Instead of using a separate small test dataset, we can divide the training dataset into k portions and then use 1 portion for testing and k-1 for training, and then repeat for different portions. Doing that, a more accurate predictive accuracy of a classifier can be achieved.

3. Leave-one-out cross validation
Instead of dividing the training dataset into k different portions, only one instance is kept for testing and the rest is for training.

Causation vs. correlation

We are interested in causation but usually we mistakes it with correlation.

1. For example, wearing red clothes does not mean lucky. There might be several instances that they are occurred together but wearing red cloth does not cause you good luck or bad luck.

2. In order to test if one thing causes another we can apply the control group in experiments like the way they test new drugs.

-For example, a new drug for treating depression is being developed, however we need to test if it causes the patient no more depression? We do this by having two groups of "depressed" patients. One is given the new drug and the other is given a placebo (i.e. the drug is just a candy). By analysing the results from these two groups we can decide if the new drug is the cause for treating the patient or not.
