What is Data Science?
The Science of combining capital processes, algorithms and many such best tools to collect, manage and analyze the most important data to make business decisions is Data Science.
Who is a Data Scientist?
A computing professional beholding the skill of data collection, data storage and management and data analysis enabling the organization to make data driven decisions quickly are Data Scientists.
In-Demand Data Science Skills
Some of the most In-Demand Data Science Skills are:
Understanding of Math & Statistics
Data Science is all about extracting the required information from the data. In depth understanding of mathematical probabilities and statistical methodologies helps in data analysis.
Majority of the data science models are built using one or more, known or unknown variables. Thus, the in depth understanding of multivariate calculus is the key requirement to develop Machine Learning models.
The detailed understanding of functions such as Logit, Cost, rectified Linear unit, Step, Sigmoid etc. is very much required to deal with the large data. Apart from these functions, the detailed understanding of Matrix algebra.
vector Algebra and Differential and Integral calculus helps the Data Scientists to develop and understand the systems at faster pace.
Programming Skills for Data Science
In order to achieve the objective to transform the raw data into business insights, Programming skills plays the crucial role. Among all the programming languages, the go to languages are Python and R, Python being the lingua franca in the data science field.
Skill to wrangle the Data
The process of removing imperfections from the raw data to get the data which can be easily analyzed is known as Data Wrangling. The entire process includes acquiring of the data, combining the data with relevant fields and cleansing the data. In short mapping of the raw data from one form to the other to set up the data to get business insights.
Database management is prerequisite of Data analysis. The basic requirements for a Database Management System is the family of programs to edit and manipulate the data and the operating system to provide the specific data.
The special skills set will definitely make you stand out from the crowd when the field and hence the number of jobs in the market are increasing at the faster pace.
