Gradients are everywhere in ML and they are essential.

Gradient descent, vanishing gradients, exploding gradients...

We use gradients in deep learning and other algorithms to train models and optimize them.

But what does Gradient mean?

Let's figure out 🔽

To understand gradients first we need to know derivatives. I know it sounds horrible, but stay with me!

In mathematics, the derivative is the rate of change of a function's output with respect to the input.

The good news? We can visualize it!

Check 1. graph.

Visually the derivative is the slope of the tangent line to the graph of the function at a point.

How to interpret a derivative?

Look at the 2. graph:

A positive derivative indicates an increase. (Point A)

A derivative of 0 indicates no change. (Point B)

A negative derivative indicates a decrease. (Point C)

(Reading from left to right)

At A the slope of the tangent is steep. A small change in input will result in a big change in output.

At C the slope is flatter. A small change in input will result in only a small change in output.

What is a gradient?

A gradient is a derivative of a function with more input variables. So a gradient is the same as a derivative but with more dimensions.

In ML, we have a set of parameters that define a model, so we use gradients.

Why knowing the derivative/gradient is good?

Because we can optimize.

The derivative can tell how to change the input in order to increase or decrease the output, so we can get closer to the minimum or maximum of a function.

Look at the 3. graph:

At A the gradient is negative and we are far from the minimum. We know that we need to change input dramatically. Since A is negative, we need to go to the right to reach a minimum.

At C the gradient is positive, but it is flatter than A, meaning that we are closer to a minimum. C is positive so we need to go to the left to reach the minimum.

At B the gradient is 0, so we know that we reached the minimum.

Looking for the minimum. Sounds familiar?

This is exactly what gradient descent does!

In gradient descent, we can determine how changing each parameter will affect the cost function.

At every point, we know how to tweak the inputs, so the cost function will get closer to the minimum (where the derivative is 0).

That's it for today.

A very thoughtful decision to open an IIT- Delhi campus in Abu Dhabi. India's advancement in the education sector is a noteworthy achievement. India can share this with the countries, particularly the global South, seeking collaboration to develop academic institutions.
