What is a neuron?

 

Linear Regression

Sigmoid or Logit function or Activation function.
In our houses, we have LED lights that light up on turning on the switch and turn off on turning off the switch so similarly activation function gives yes or no results i.e., 0 or 1 results.
In ML the input function (dependent variable) i.e. the age here is called a feature.


This oval here represents a neuron. Neuron is basically a combination of linear equations and activation functions.

What is Artificial Intelligence? Artificial intelligence (AI)  is the theory and development of computer systems capable of performing tasks that historically required human intelligence, such as recognizing speech, making decisions, and identifying patterns. AI is an umbrella term that encompasses a wide variety of technologies, including machine learning, deep learning,  and natural language processing (NLPs) .  What is Natural Language Processing? What it does : NLP is like teaching computers to understand and talk like humans. It helps computers understand what we say or write and respond in a way that makes sense. Example : When you ask Siri a question and she understands what you mean, that's NLP at work. It's also used for things like translating languages or checking grammar in text. What is Machine learning? What it does : ML is like teaching computers to learn from examples and make decisions on their own. It's about training computers to recognize patterns in dat

  Types of Machine Learning 1. Supervised learning: Learning from Examples : Imagine you're a teacher helping a student learn to recognize different animals. You show the students pictures of animals and tell them the name of each animal in the picture. The student learns by looking at the pictures and listening to your labels. Labeled Data: In machine learning, the pictures are called "data," and the names of the animals are called "labels." Together, they make "labeled data." Training a Model: The student is like the machine learning model. During the "training" phase, the model looks at the data (pictures) and the labels (animal names) to understand the relationship between them. Making Predictions: After learning from many examples, the model can look at a new picture (one it hasn't seen before) and guess the animal's name. This guessing is called "making predictions." Improvement Over Time: Just like the student gets b

  Neural networks  Imagine a group of people who have never seen " KOALA" (an animal) in their life!!! So now our job is to teach them if any image is of "KOALA" or not.... We create a team and ask each and every student to work and study each feature of the koala, such as Mike can work on detecting eyes, Jyoti works on forelimbs, Chen can work on hindlimbs, and Mohan can work on the nose. So they make assumptions by using a score of 0 to 1. For example, where 0 means definitely not Koala's eyes, 0.5 means maybe or maybe not Koala's eyes and 1 means definitely Koala's eyes. Then Serena, their superior notes down their observations and based on a formula tells us finally if an animal is a Koala or not.   This is nothing but a neural network. Each individual person here is an individual neuron. They're working on a particular subtask and pass the result of their subtask to the next group. Here, Serena and Nidhi are the hidden layer, Mike, Mohan, etc fo
