## Feature Engineering Tutorial Series 6: Variable magnitude

Does the magnitude of the variable matter? In Linear Regression models, the scale of variables used to estimate the output matters. Linear models are of the type y = w x + b, where the regression coefficient w represents the expected change in y for a one unit change in x Read more…

## Feature Engineering Tutorial Series 5: Outliers

An outlier is a data point which is significantly different from the remaining data. “An outlier is an observation which deviates so much from the other observations as to arouse suspicions that it was generated by a different mechanism.” [D. Hawkins. Identification of Outliers, Chapman and Hall , 1980.] Should Read more…

## Feature Engineering Tutorial Series 4: Linear Model Assumptions

Linear models make the following assumptions over the independent variables X, used to predict Y: There is a linear relationship between X and the outcome Y The independent variables X are normally distributed There is no or little co-linearity among the independent variables Homoscedasticity (homogeneity of variance) Examples of linear Read more…

## Feature Engineering Series Tutorial 3: Rare Labels

Labels that occur rarely Categorical variables are those whose values are selected from a group of categories, also called labels. Different labels appear in the dataset with different frequencies. Some categories appear more frequently in the dataset, whereas some other categories appear only in a few number of observations. For Read more…

## Feature Engineering Series Tutorial 2: Cardinality in Machine Learning

Cardinality refers to the number of possible values that a feature can assume. For example, the variable “US State” is one that has 50 possible values. The binary features, of course, could only assume one of two values (0 or 1). The values of a categorical variable are selected from Read more…

## Feature Engineering Series Tutorial 1: Missing Values and its Mechanisms

Missing data, or missing values, occur when no data / no value is stored for certain observations within a variable. Incomplete data is an unavoidable problem in most data sources, and may have a significant impact on the conclusions that can be derived from the data. Why is data missing? The source of missing Read more…

## Types of Data types every Data Scientist should know

One of the central concepts of data science is gaining insights from data. Statistics is an excellent tool for unlocking such insights in data. In this post, we’ll see some basic types of data(variable) which can be present in your dataset. What is a Variable? A variable is any characteristic, Read more…

## Data Visualization with Pandas

Data visualization is the discipline of trying to understand data by placing it in a visual context so that patterns, trends and correlations that might not otherwise be detected can be exposed. pandas is a fast, powerful, flexible and easy to use open source data analysis and manipulation tool, in Python programming Read more…
