Fundamental steps inartificial neural networks-based medical diagnosis – Pubrica

 

Introduction:

The process of artificial neural network analysis rises from the clinical situations that give a brief overview of the purposes of medical diagnosis with enormous confidence. Pre peer review for the neural network observes the patient's data to detect a specific disease. Once after finding the target, the next step is to proceed the experiment with laboratory and instrumentation processes that give information about the patient's health conditions. There are many ways to perform these processes. Many tools are there to perform the tasks. However, careful selection of tools is essential to avoid noise-based instruments in the first stage. The next stage is to formulate a database and to validate it. Likewise, there few significant steps involved in performing artificial neural network analysis, and this blog explains the steps in the artificial neural network using peer review service.

 

Steps involved in an artificial neural network:

·         Features selection

·         Building the database

ü  Data cleaning and preprocessing

ü  Data homoscedasticity

·         Training and verification of database using artificial neural network

ü  Network type architecture

ü  Training algorithm

ü  Verification

ü  Robustness of artificial neural network-based approaches

·         Testing in medical practice

Features selection:

Diagnosis ofany specific disease depends on various data. Medical professionals will extract the relevant data from each type of information to detect the most comfortable diagnosis. For artificial neural network analysis, a collection of data is known as 'Features' that can be symptoms, phytochemical analysis, or any other relevant information helps for diagnostic purposes. So it is closely related to the final diagnosis. The significance of Artificial neural networkis to grasp from previous samples, makes them very flexible and potential tools to perform medical diagnosis.

Limitations:

·         Insufficient

·         Non-specific

·         Noisy information about the problem

·         Redundant

The selection of appropriate features is essential for medical diagnosis using different medical approaches with the help of medical peer review services.

Tools used:

·         Mathematical means of data

·         Genetic algorithm

·         Principal component analysis

Building the database:

The "example" cases are a unified database for the neural network is training. An "example" provides patient values for the selection, collection and evaluation.

ü  Data cleaning and preprocessing:

Preprocess the training database before the evaluation process by the neural network. Scale the data between the interval for the logistic purpose. Besides, the demonstration of a few cases,  some data are missing and remove it from the database set to improve the performance of the neural network.

Training and verification of database using artificial neural network:

ü  Network type and architecture:

There are many other network models such as Bayesian, recurrent, or fuzzy, stochastic but multilayer feed-forward neural networks are most common. The optimal network architecture selection is the first stage. The testing networks using a various number of hidden layers and nodes use them. It gives the optimal architecture for which the minimum value of E  for both training and verification.

ü  Training algorithm :

Different types of training algorithms are available."Network learning" section, use of two training parameters:

(i)                 learning rate

(ii)               momentum.

 

ü  Verification:

Verification of dataset from various data for training for the artificial neural networks-based medical diagnosis is there in the process.

ü  Robustness of artificial neural network-based approaches:

The artificial neural network can tolerate a  level of noise in the data. Consequently, they give sufficient prediction accuracy. This noise may sometimes cause false results, mainly when modelling a complicatedsystem like the health condition of a human body.One of the best ways to avoid this is to perform the process by an experienced clinician knowing the discriminative power of the artificial neural network systems having a peer-reviewed publication.

Testing in medical practice:

The final step in the artificial neural network-aided diagnosis is testing medical practice. Examination of New patient, the network's outcome must be careful. Medical data of patients must be correct when including it in the training database. The comprehensive and extensive evaluation of ANN diagnosis applications in the clinical sector is necessary for different institutions.

Conclusion:

The ANN is a powerful tool for physicians to perform diagnosis. It has several advantages, like processing a large amount of data and providing relevant information.
