Artificial Neural Networks: Mimicking the Human Brain for Better Productivity

Artificial intelligence has come a long way since its inception. Early computer scientists looked to the human brain for clues on how to Create a learning machine. They discovered that nothing is better at learning than the human brain, which is made up of special cells called neurons. These neurons are connected to each other in a biological neural network, which is how the brain processes information and recognizes Patterns.

To mimic human neurons, early AI scientists created their own simple artificial neurons in software. These neurons take in multiple signals as inputs, pass them through the neuron, and combine and process them using simple math into a new signal going out. However, one neuron alone doesn't do much. The full potential of this idea is only unleashed when the artificial neurons are connected together to make an artificial neural network. This is what allows computers to recognize images, drive cars, and make some truly weird art.

The Human Brain and Neurons

The human brain is a complex organ that is responsible for our thoughts, emotions, and actions. It is made up of billions of neurons that are connected to each other in a biological neural network. Each neuron has two ends: input signals enter in on one end, they're combined together inside the neuron, and leave out the other end as a single output. This process is what allows the brain to process information and recognize patterns.

Artificial Neurons

Artificial neurons are simple software programs that mimic the behavior of human neurons. They take in multiple signals as inputs, pass them through the neuron, and combine and process them using simple math into a new signal going out. While one neuron alone doesn't do much, the full potential of this idea is unleashed when the artificial neurons are connected together to make an artificial neural network.

Artificial Neural Networks

Artificial neural networks are made up of multiple layers of interconnected artificial neurons. There are input layers, any number of Hidden layers, and output layers. The output of one layer of neurons becomes the input to the next layer, and so on. This allows the network to process complex information and recognize patterns.

Movie Recommendation System

To understand how artificial neural networks work, let's build a movie recommendation system. We'll use critics' reviews to guess how much You'll like a movie, and then use your feedback to make the system better.

We have three movie critics: Ali, Bowie, and Casey. Each one rates a movie anywhere from one to five stars. We'll build a single artificial neuron that takes in each critic's rating as input and outputs a movie rating.

Training the Neuron

At first, the critics' opinions all carry the same weight and are counted equally. But when you watch the movie and give it a rating, the weight of each critic's opinion is recalculated Based on your rating. Your rating is closer to that of Bowie and Casey, so their opinions get more weight. You didn't agree with Ali's single star review, so that weight goes down. This process repeats over and over until we've trained a system to know our preferences and recommend movies that we'll probably enjoy.

Powerful Neural Networks

Powerful neural networks have millions of neurons arranged in layers. They are used in real-world media, music, and shopping recommendation systems, using ratings for millions of everyday users in those neural networks. Everyone has a HAND in modifying the weights.

Real-World Applications

Neural networks have many real-world applications, including growing healthier food, predicting floods and forest fires, aiding wildlife conservation, and even detecting and curing disease.
