Neural Networks(NN)

Neural Networks(NN)

• 
  
• Neural Networks reflect the behavior of the human brain.
• Allowing computer programs to recognize patterns and solve common problems in the fields of AI, machine learning, and deep learning.

How Neural Networks(NN) learn 

There are three ways neural networks work.

1. Supervised Learning is where a computer algorithm is trained on input data that has been labeled for a particular output .
2. Unsupervised Learning is in which a system learn through data-sets created by its own. In unsupervised is not labeled.
3. Reinforcement Learning Learning through feed-back or trial and error method is called Reinforcement learning.

Neural networks vs Human Nervous system

• As we know that computers have a complex structure and they also can complete any complex tasks in a short time.
• Humans cant do any complex tasks like computers or AI .
• Computers are very fast and intelligent than humans but there are some easy tasks that computers cannot do it. Example: computers cannot babysit a child.

• Neural networks in everyday life

• Social media

  The people who are in the social media platforms such as facebook and instagram, people connect themselves with other peoples and make friends online in which people upload their photos or selfies shows to other people, we can also see who else are in their photo and show them their profile names automatically when clicked on the image.

  Online shopping

  We all know, whenever we are shopping for one thing we end up buying a lot and this happens to all of us most of the time so the technology behind this is recommendations and what we search for.

  → Recommendations

  Amazon shows you recommendations depending on the behaviour of the individual interests , Amazon makes use of Artificial Neural Networks(ANN)to train its algorithms to learn the pattern and behaviour of its users. that is why amazon have such a good services and make sure to improve their quality.

  → Search

  Yor amazon searches are also use neural network and your amazon return a list of the most relevant products related to your search, It uses past patterns and adapts to what is important for the customer in question.

  Online Banking

  Online banking has become one of the most common use in everyday daily life, neural networks is used , where you write a cheque you write with your own handwriting and then it is converted into text with the help of neural networks.

  Voice-to-text

  The voice to text is now a days is very helpful and it is one of the common features on smartphones, in this Technology there is a hand of neural networks.

  Smart Personal Assistant

  It is one of more common features of voice to text technology , this technology made this new invention of smart personal assistant which is similar as real life personal assistant. for example: Siri,alexa and google are some of the example of smart personal assistants .

• Applications of neural networks

• Some of the applications of neural networks are :

  • Speech recognition
  • Character recognition
  • Spell checking
