Artificial Neural Network Basic Concepts



Artificial Neural Network Basic ConceptsDefinition of Artificial Neural Network Basic Concepts - An artificial neuron network (ANN) is a computing System model based on the structure and functions of biological neural networks. The system learn to do tasks without specific programming. The ANN is a collection or group of interconnected units called Artificial Neurons. The neurons are organised in layers. Each interconnection between neurons transmit a unidirectional signal with strength. If the combined incoming signals are strong, the receiving end neuron activate and propagate signal to the downstream neurons interconnected to it. The main moto of the neural network approach is to solve problems as human brain can do.


The inventor of the first neurocomputer was Dr. Robert Hecht-Nielsen, according to him "a computing system made up of a number of simple, highly interconnected processing elements, which process information by their dynamic state response to external inputs".


Types of Artificial Neural Networks (ANN)



There are two types of ANN model – Feed Forward and Feedback.


Feedforward ANN –


In this model, the information is flowing in unidirectional mode. The communication between transmitter and receiver is not maintained due to unidirectional propagation of information. These type of model is used in Pattern Generation, Recognition and Classification. There is no feedback loops exists in this type of model. This type of model have fixed inputs and outputs.


Feedback ANN – The looping is allowed in this model. The model also contain feedback loop which is helpful during content addressable memories use.


Application Areas of Artificial Neural Networks (ANN)




  1. Medical Areas− Cancer cell analysis, EEG and ECG analysis, transplant time optimizer and others.

  2. Electronics and Telecommunications areas− real-time spoken language translation, Image and data compression, automated information services, Code sequence prediction, IC chip layout, chip failure analysis, machine vision, voice synthesis.

  3. Speech recognition, speech classification, text to speech conversion.

  4. Time Series Prediction − ANNs are used to make predictions on stocks and natural calamities.

  5. Signal Processing − Neural networks can be trained to process an audio signal and filter it in the hearing aids.

  6. Software − Facial Pattern recognition, optical character recognition

  7. Financial aids – Exist as loan advisor, mortgage screening, corporate bond rating, portfolio trading program, corporate financial analysis, currency value prediction, document readers, credit application evaluators.



Limitation of Artificial Neural Network (ANN)



The Backpropagation Neural Network properties act like a black boxes. In fact the user has no other choice than to feed it input and await for output. The Network is also slower than other types of network which kill time of CPU.


Characteristics of Artificial Neural Networks (ANN)




  1. Choice of Model – simpler to complex.

  2. Robustness

  3. Learning & Simplified algorithms



This is all about Artificial Neural Network Basic Concepts, in next article we will discuss regarding another Network applications.

Fix Windows could not find a driver for your network adapter error


A Computer run smoothly with the coordination of Software & Hardware. In the absence of any one it will not run at all. Software being the Master utilizes each hardware attached to the System. And each hardware is operated with the help of Device Drivers installed in it. Operating System (OS) uses these device drivers to control & utilize each hardware when needed. Each hardware connected to the system must have their own Device Driver installed. A device driver is a program to initiate a hardware when required by Operating System.




Suppose, you want your PC to connect to the Network, it can only be possible when your PC has network related Device Driver. These Device Drivers are easily downloaded from Manufacturer Websites. In this article we focus on Network related problem. Suppose, your PC not obtaining Network connectivity. And each time you are getting an error message saying "Windows could not find a d…

Fix This Site Can't Be Loaded from The Cache Chrome Error


This Site Can’t Be Loaded from The Cache - Today, there are several browsers available with extensive features on it. Each browser has its own importance and working principle. Some of the popular browsers available online are Google Chrome, Mozilla Firefox, Opera Mini, Internet Explorer, UC Browser, Safari, Microsoft Edge, Swift fox etc. The popularity of these browsers depends upon the features available in it.

Among them Google Chrome is the newest and mostly used browser around the world. Holding lots of feature make it more complex and hence more prone to errors. The types of error come up with the level of complexity of the program. If you are Chrome user and facing one of such error then read the full article.

Change Facebook Profile Picture Leaving All Unknown - Today, we spend lots of time in Social media platforms such as WhatsApp, Facebook, Instagram, Skype, YouTube, Twitter etc. We love to share Images & Videos with our friends via these platforms. These applications are largely used on Smartphones. We need to download concerned apps from inbuilt software, Play Store in Android Platform.


After downloading the App, we create an ideal account with a profile picture. We join the network by sending friend request. When request is accepted, we are added to such a community. In this article we take a close look on Facebook. Facebook is vastly used all around the world. Two person residing miles away can also share their views easily.
