# T1 - Principal component analysis
|
||||
|
||||
## Study the dataset
|
||||
|
||||
1. Choose 2 datasets from Kaggle or any source in Internet with more than 6 dimensions.
|
||||
1. For each dataset, determine which feature is discrete or continuous? quantitative or qualitative? numerical or categorical? Explain.
|
||||
1. What are the issues lying within data? for example: missing data, incorrect data? Do you
|
||||
1. need to prepare data?
|
||||
1. Is there any label in the datasets? Explain.
|
||||
1. Calculate mean, variance, covariance, correlation of the selected datasets. How do you calculate these measures for categorical features (if any)?
|
||||
1. Find the most corelated couple of features of each dataset. Comment on the results.
|
||||
Is there any missing data? How do you handle this issue?
|
||||
|
||||
## PCA
|
||||
|
||||
1. Apply PCA on the two selected datasets. Describe how you select the principal components.
|
||||
Is there any difference while using principal components with highest and lowest values?
|
||||
1. Vary the number of used principal components, analyze and comment on the obtained results.
|
||||
1. Visualize data distribution in 2D.
