Sigmoid function

So let me talk about some practical business that fits the model of what's behind my head here.

It's called the sigmoid curve.

It's an interesting illustration, and it has to do with all lives have a tendency to grow, plateau, and decline.

That's the arc of your physical body.

China wants us to serve China like Hong Kong serves China.

But with these scenarios that I'm talking about, You run into the sigmoid curve.

Let's talk about the sigmoid curve.

Sigmoid curve is a business model that says that in the life cycle of anything, it rises, it rises.

This is going to be, we'll call this fruit.

I'll put a big grape thing here.

Time.

This is going to be time.

We use activation functions to bend the output.

Historically, one of the first ones used was the sigmoid function.

Sigmoid.

It takes any input number, no matter how huge or how negative, and mathematically squashes it into an S-shaped curve between 0 and 1.

OK, so a massive input becomes something close to a one and a huge negative input gets squashed down to almost zero.
