What is Data Science?
Data science is the process of extracting knowledge from data. Data is raw information that needs to be analysed and interpreted to derive insights. The future of work will be a time when people will not have to spend their time doing tedious tasks, but instead focus on what they are best at. Data scientists will have the power to automate more and more processes, freeing up human workers for more complex and creative tasks.
Exploratory Data Analysis Techniques:
Exploratory data analysis is a set of research methods in data science. It is used to explore data, identify patterns and relationships, and generate hypotheses for further testing. EDA techniques are used to reveal the hidden relationship between the variables in a dataset.
Some of the EDA techniques include:
- Scatterplot
- Histogram
- Boxplot
- Violin Plot
Statistical Techniques for Data Science & Machine Learning
Statistical inference is an important concept in data science and machine learning. It is a technique that uses probability theory and statistics to make decisions or predictions about the population from a sample. Statistical inference includes Bayesian inference, which is a method of statistical analysis that makes use of Bayes’ theorem to update our beliefs based on new information.
Bayesian inference is used in many machine learning algorithms, such as decision trees, random forests, and support vector machines. Statistical inference can be used in various fields, such as medicine, engineering, economics and social sciences.
Regression Techniques for Data Science
The objective of regression is to create a model that can predict the value of a variable (dependent variable) based on other variables (independent variables). Regression analysis is one of the most popular data science techniques. It’s often used to predict future outcomes or make decisions. It’s important to remember that regression is not a perfect technique and it doesn’t work in all cases.
The goal of this article is to introduce you to some of the most common machine learning regression techniques and provide some examples for each.
Classification Techniques for Data Science & Machine Learning:
Classification techniques are important in data science and machine learning. They are used to categorize data into different groups. There are many classification techniques and algorithms out there, but the most popular ones include:
1. Bayesian Classifiers
Bayesian Classification is a machine learning technique that is used to classify objects. The Bayesian classifier is the most popular classification algorithm and is used extensively in medical diagnosis, spam detection, targeted advertising, text-to-speech synthesis and other related fields.
