Plotting for exploratory data analysis (EDA)
exploratory data analysis (EDA) is an approach to analyzing data sets to summarize their main characteristics, often with visual methods. A statistical model can be used or not, but primarily EDA is for seeing what the data can tell us beyond the formal modeling or hypothesis testing task.

Probability and Statistics
Dimensionality reduction and Visualization:
In machine learning and statistics, dimensionality reduction or dimension reduction is the process of reducing the number of random variables under consideration, via obtaining a set of principal variables. It can be divided into feature selection and feature extraction.

Statement:
The experiments have been carried out with a group of 30 volunteers within an age bracket of 19-48 years. Each person performed six activities (WALKING, WALKING_UPSTAIRS, WALKING_DOWNSTAIRS, SITTING, STANDING, LAYING) wearing a smartphone (Samsung Galaxy S II) on the waist. Using its embedded accelerometer and gyroscope, we captured 3-axial linear acceleration and 3-axial angular velocity at a constant rate of 50Hz.
The objective is to classify activities into one of the six activities performed.
- Data Type
- csv files
- Train.csv (Triaxial acceleration, estimated body acceleration, Triaxial Angular velocity, a 561-feature vector with time and frequency domain variables, activity label)
- Test.csv it is same as train.csv except the label is missing which we need to predict
- Data Size: 58 MB
