Smart And Deep Learning Techniques. The term “AI” is used casually every day. You hear budding developers say they want to learn AI. He also hears executives saying they want to implement AI in their departments. But very often, many of these people don’t understand what AI is.

Smart And Deep Learning Techniques.

Artificial intelligence is the duplicate of human intelligence in computers.
When AI research began, researchers were trying to replicate human intelligence for specific tasks, like playing a game.
They introduced many rules that the computer had to follow. The laptop had a precise list of possible events and was decided based on individuals’ policies.

Machine learning refers to the capability of a machine to learn with massive data sets in its place of hard-coded regulations.
ML allows computers to learn by themselves. This type of learning improves the processing power of modern computers, which can efficiently process large data sets.
Supervised learning vs. unsupervised learning
Supervised learning involves using labeled data sets that have expected inputs and output.
When you teach an AI using supervised learning, you give it an input and tell it the estimated production.

But the output generated by the AI is incorrect. It will readjust its calculations. This process is done iteratively over the dataset until the AI makes no more errors.

An example of supervised learning is an AI that predicts the weather. Learn how to predict the weather using historical data. This training data has inputs (pressure, humidity, wind speed) and outputs (temperature).
Unsupervised learning is the machine learning task that uses data sets without a specific arrangement.
When you train an AI using unsupervised knowledge, you let the AI perform logical data classifications.

Now, how does deep learning work?

You are now ready to know what Deep Learning is and how it works.

Deep Learning is a technique of machine learning. This allows us to train an AI to predict output, given a set of inputs. Both supervised and unofficial knowledge can be used to train AI.

We determination learn how deep learning works by creating a hypothetical airline ticket price estimation service. However, We will train you using a supervised learning method.
We want our airfare price estimator to predict the price using the following inputs (return tickets are excluded for simplicity):

origin airport
Destination airport
Date of departure
Airline company
neural network

Let’s look indoor the brain of our AI.

Just like animals, the brain of our AI estimate has neurons. Circles represent them. These Neurons are interconnected.
Neurons are grouped into three diverse types of layers:

input layer
Hidden layer(s)
output layer
The input layer receives the input data. Our container has four neurons in the input layer: departure airport, destination airport, departure date, and airline. The critical layer passes the inputs to the first unknown layer.
The hidden layers present mathematical calculations on our inputs. One of the challenges in building neural networks is deciding how many hidden layers and how many neurons are for each layer.

“Deep” in Deep knowledge refers to having more than one hidden layer.

The output layer returns the output data. In our case, this gives us the price prediction.
So how do you calculate the price forecast?

This is somewhere the magic of Deep Learning begins.

Each association between neurons is associated with a load. This load dictates the importance of the input value. The initial weights are set at random. When it comes to predicting the price of an airline ticket, the departure date is one of the most critical factors. Therefore, the neural connections of the start date will carry significant weight.
Each neuron has an activation function. These functions are difficult to understand without mathematical reasoning.

In a nutshell, one of its purposes is to “normalize” the neuron’s output.

Once an input dataset has passed through all the neural network layers, it returns the output data through the output layer.

Nothing complicated, right?

Neural network training and
AI is the hardest part of deep learning. Why?
You need a large data set.
It would be best if you had a lot of computing power.
We need to find historical ticket price data for our airline ticket price estimator. And due to a large number of possible combinations of airports and departure dates, we need a massive list of ticket prices.

To train the AI, we need to feed it the inputs of our dataset and compare its outputs with the outputs of the dataset. Since the AI is not yet trained, your results will be wrong.

Once we’ve looked at all the data, we can create a function that shows us how far the AI results were from the actual results. This purpose is called the cost purpose.
Ideally, we want our price tag function to be zero. This is when the outputs of our AI are the same as the outputs of the dataset.

How to reduce the cost function?

We change the weights between the neurons. We could randomly adjust them until our cost function is low, but that’s not very efficient.

Instead, we’ll use a technique called Gradient Descent.

Gradient descent is a technique for finding the minimum of a function. In our case, we seek the minimum of the price tag purpose.
It works by changing the weights within small increments following each iteration of the dataset. We can see the minimum’s direction by calculating the cost function’s derivative (or gradient) at a specific set of weights.
It would be best to loop your dataset multiple times to minimize the cost function. That’s why you need a lot of computing power.

The updating of the weights by gradient descent is done automatically. This is the magic of Deep Learning!
