Application of Soft Computing

Application of Soft Computing:

 

There is a major paradigm shift in the methods of computing which reflects the remarkable growth of the human mind. One major change that we’ve witnessed is the evolution of hard computing to soft computing.

The techniques used by soft computing have basically originated from various mathematical concepts, like fuzzy logic.

Soft computing provides insights into real-world problems and is just not limited to theory. It has tolerance for uncertainty and is imprecise in nature due to which it has spread widely into various industries.

So what is soft computing?

Soft computing is the process of solving real-life complex problems using approximate calculations and gives solutions that are not very specific in nature just like the human brain works, which, unlike traditional computing, focuses on impartial truths and approximates.

The constituents of soft computing are:

  • Fuzzy Logic (FL)
  • Evolutionary Computation (EC)
  • Machine Learning (ML) and
  • Probabilistic Reasoning (PR)

There are various problems in the world that require vast resources and computations to be made which cannot be solved, just by logical means. Soft computing has emerged as a way of solving problems, the way humans do.

Let’s take a look at some of the applications of soft computing across different industries-

    1. Handwritten Script Recognition
    2. Image Processing and Data Compression
    3. Automotive Systems and Manufacturing
    4. Soft computing based Architecture
    5. Decision Support System
    6. Power System Analysis

Handwritten Script Recognition using Soft Computing

Handwritten Script Recognition is one of the demanding parts of computer science. It can translate multilingual documents and sort the various scripts accordingly.

It uses the concept of “block-level technique” where the system recognizes the particular script from a number of script documents given.

It uses a Discrete Cosine Transform (DCT), and discrete wavelets Transform (DWT) together, which classify the scripts according to their features.

Image Processing and Data Compression using Soft Computing

Image analysis is one of the most important parts of the medical field. It is a high-level processing technique which includes recognition and bifurcation of patterns.

Using soft computing solves the problem of computational complexity and efficiency in the classification. Techniques of soft computing include Genetic Algorithms, Genetic Programming, Classifier Systems, Evolution Strategies, artificial life, and a few others, which are used here.

These algorithms give the fastest solutions to pattern recognition. These help in analyzing the medical images obtained from microscopes as well as examine the X-rays.

Use of Soft Computing in Automotive Systems and Manufacturing

The use of soft computing has solved a major misconception that the automobile industry is slow to adapt. Fuzzy logic is a technique used in vehicles to build classic control methods.

It takes the example of human behavior, which is described in the forms of rule – “If-Then “statements.

The logic controller then converts the sensor inputs into fuzzy variables that are then defined according to these rules. Fuzzy logic techniques are used in engine control, automatic transmissions, antiskid steering, etc.

Soft Computing based Architecture

An intelligent building takes inputs from the sensors and controls effectors by using them.

The construction industry uses the technique of DAI (Distributed Artificial Intelligence) and fuzzy genetic agents to provide the building with capabilities that match human intelligence.

The fuzzy logic is used to create behavior-based architecture in intelligent buildings to deal with the unpredictable nature of the environment, and these agents embed sensory information in the buildings.

Soft Computing and Decision Support System

Soft computing gives an advantage of reducing the cost of the decision support system. The techniques are used to design, maintain, and maximize the value of the decision process.

The first application of fuzzy logic is to create a decision system that can predict any sort of risk. The second application is using fuzzy information that selects the areas which need replacement.

Soft Computing Techniques in Power System Analysis

Soft computing uses the method of Artificial Neural Network (ANN) to predict any instability in the voltage of the power system.

Using the ANN, the pending voltage instability can be predicted. The methods which are deployed here, are very low in cost.

Soft Computing Techniques in Bioinformatics

The techniques of soft computing help in modifying any uncertainty and indifference that biometrics data may have.

Soft computing is a technique that provides distinct low-cost solutions with the help of algorithms, databases, Fuzzy Sets (FSs), and Artificial Neural Networks (ANNs).

These techniques are best suited to give quality results in an efficient way.

Soft Computing in Investment and Trading

The data present in the finance field is in opulence and traditional computing is not able to handle and process that kind of data.

There are various approaches done through soft computing techniques that help to handle noisy data.

Pattern recognition technique is used to analyze the pattern or behavior of the data and time series is used to predict future trading points.

Recent developments in soft computing

People have started using techniques of soft computing like fuzzy sets theory, neural nets, fuzzy neuro system, adaptive neuro-fuzzy inference system (ANFIS), for driving various numerical simulation analysis.

Soft computing has helped in modeling the processes of machines with the help of artificial intelligence. Also, there are certain areas where soft computing is in budding stages only and is expected to see a massive evolution:

  • Big Data
  • Recommender system
  • Behavior and decision science
  • Mechanical Engineering
  • Computer Engineering
  • Civil Engineering

Data Warehousing - An Overview

Anurag Information Technology (IT) has historically influenced organizational performance and competitive standing. The increasing processing power and sophistication of analytical tools and techniques have put the strong foundation for the product called data warehouse. There are a number of reasons that any organization should consider a data warehouse, which can be the critical tool for maximizing the organization’s investment in the information it has collected and stored throughout the enterprise. IT managers need to understand the rationale and benefits of data warehouses because they may need to design and implement, or procure this kingpin of business intelligence. The data warehouses are supposed to provide storage, functionality and responsiveness to queries beyond the capabilities of today's transaction-oriented databases. Also data warehouses are set to improve the data access performance of databases. Traditional databases balance the requirement of data access w...

Standard and Formatted Input / Output in C++

The C++ standard libraries provide an extensive set of input/output capabilities which we will see in subsequent chapters. This chapter will discuss very basic and most common I/O operations required for C++ programming. C++ I/O occurs in streams, which are sequences of bytes. If bytes flow from a device like a keyboard, a disk drive, or a network connection etc. to main memory, this is called   input operation   and if bytes flow from main memory to a device like a display screen, a printer, a disk drive, or a network connection, etc., this is called   output operation . Standard Input and Output in C++ is done through the use of  streams . Streams are generic places to send or receive data. In C++, I/O is done through classes and objects defined in the header file  <iostream> .  iostream  stands for standard input-output stream. This header file contains definitions to objects like  cin ,  cout , etc. /O Library Header Files There are...

Normalization in DBMS: 1NF, 2NF, 3NF and BCNF in Database

Normalization   is a process of organizing the data in database to avoid data redundancy, insertion anomaly, update anomaly & deletion anomaly.  Anomalies in DBMS There are three types of anomalies that occur when the database is not normalized. These are – Insertion, update and deletion anomaly. Let’s take an example to understand this. Example : Suppose a manufacturing company stores the employee details in a table named employee that has four attributes: emp_id for storing employee’s id, emp_name for storing employee’s name, emp_address for storing employee’s address and emp_dept for storing the department details in which the employee works. At some point of time the table looks like this: emp_id emp_name emp_address emp_dept 101 Nikhil Kangra D001 101 Nikhil Kangra D002 123 Ashish Shimla D890 166 Rahul Pathankot D900 166 Rahul Pathankot D004 The above table is not normalized.  Update anomaly : In the above table we have two rows for employee Nikhil as he belongs ...
