Data science.
This is a short post introducing 3 branches of data science
Data science involves statistical, mathematical,programming and problem solving techniques and are broadly classified into
Business intelligence.
Traditional methods.
Machine learning.
Business intelligence(BI) - analysing the acquired past data, and understanding the past business performance in form of reports/dashboards to improve the future performance.
Why sales is low?
Which city had the highest sales?
When did it happen?
What are the goods that are sold the most?
Traditional methods - involves set of methods that are derived mainly from statistics.
Used for forecasting future performance with great accuracy.Methods like Regression analysis, clustering.
Machine learning - Machine learning is the study of algorithms that improve automatically through experience.It is a trial and error process. Each consecutive trial is better than the previous.
ML is classifies as supervised, unsupervised and reinforcement learning.
In the next post we will be learning about Regression analysis.
Thank you!
