# Linear Algebra for Data Science and Machine Learning

Linear Algebra is a vital cog in data scientists’ skill set that learners don't bother much about because they find maths intimidating.

Linear Algebra is one of the foundational blocks of Data Science and Machine Learning. It’s hard to think of algorithms or applications that aren’t implemented using linear algebra.

Programming languages like Python, R and Julia offer a plethora of packages for working with data to solve complex problems by applying linear algebra. You'll be using linear algebra to perform the required calculations and analyses efficiently. It is used for Principal Component Analysis to reduce the dimensionality of data. It is practically good for working with neural networks, the representation and processing of the network.

With a functional knowledge of Linear Algebra, you will develop a better intuition for ML and deep learning algorithms. It is your key to unlock a whole new world — you will also be able to code algorithms from scratch and make your own variations to them.

Linear Algebra can be difficult for beginners, but you can punctuate your efforts to learn the pre-requisites, internalize the basics and then build from there. For effective learning, get a good book and check out adjunctive resources to become highly prepared for learning advanced topics.
