Alright, lets move on to more interesting stuff: linear regression. Since the main focus in TensorFlow, and given the abundancy of online resources on the subject, I’ll just assume you are familiar with Linear Regressions.

As previously mentioned, a linear regression has the following formula:

linear_regression

Where Y is the dependent variable, X is the independent variable, and b0 and b1 being the parameters we want to adjust.

Let us generate random data, and feed that random data into a linear function. Then, as opposed to using the closed-form solution, we use an iterative algorithm to progressively become closer to a minimal cost, in this case using gradient descent to fit a linear regression.

Yes, I kind of jumped the guns on my initial post on Deep Learning straight into CNNs. For me this learning path works the best, as I dive straight into the fun part, and eventually stumble upon the fact that maybe I’m not that good of a swimmer, and it might be good to practice a bit before going out in deep waters. This post attempts to be exactly that: going back to the basics.

TensorFlow is a great starting point for Deep Learning/ Machine Learning, as it provides a very concise yet extremely powerful API. It is an open-source project created by Google initially with numerical computation tasks in mind, and used for Machine Learning/Deep Learning.
