Today's Discussion

A massive volume of clinical data is produced daily that possess minute and critical information as well as varied, in-depth concepts of biochemistry and the results of imaging devices. Information provided byeach kind of data must be evaluated and assigned for diagnostic processes. To simplify the diagnostic process and evade

errors in that process, artificial intelligence techniques can be adopted like computer- aided diagnosis and artificial neural networks. The b iostatistical services machine

learning algorithms can deal with a broad set of specific data and produce categorized outputs by checking the blogs in Pubric.

In-Brief

Introduction The artificial neural network has been widely used in the fields of science and technology. It is used for the optimization of data.

It predicts the outputs using the input data in fields like chemical engineering, biotechnology, healthcare, agriculture, etc., which all handles varied sets of data.

The artificial neural network can be used for modellingnon-linear systems with a complex system of variables.

Thus, most of the chemical engineering and biological processes are modelled using Artificial neural network with the help of b iostatistical consulting services.

Artificial Neural Network

Clinical biostatistics services state that Artificial neural network is the simulation of human neural architecture.

The learning and generalization potentials of human neural network inspired for the development of an artificial neural network.

It works by taking the 70% of input data to build a network then takes the remaining 15% data to train itself and at last utilize the remaining 15% data to test itself and eventually produce the optimized outputs.

The a rtificial neural network is made up of three layers, viz., – (i) input layer, (ii) hidden layer, (iii) output layer.

The schema of the neurons built inside the networkis based upon the complexity of the system.

The input layer collects the input data and transfers to the hidden layer where the data is processed to produce optimized results with s tatistical programming services.

Architecture

Every Artificial neural network has an activation function that is used for determining the output.

Each neuron is interconnected, and each connection has a weight attached possessing either positive or negative value which tends to change upon the training the network.

Overview of Artificial Neural Network in Medical Diagnosis

Seeking various uses in various fields of science,medical diagnosis field also has found the application of artificial neural network using biostatistics in clinical services.

It is used in the diagnosis of cancer, sclerosis, diabetes, heart diseases, etc.

An adaptive algorithm is developed and applied to yield maximum accuracy in outputs with the s tatistics i n clinical trials.

Cardiovascular Diseases It is the collection of diseases affecting the heart,

cardiac muscles, blood vessels, veins.

National centre of health statistics reported that leading cause of death in united states of America is these c ardiovascular diseases.

In the past, the data collected from the patients were used to develop an Artificial neural network model with the backpropagation algorithm was developed.

Contd..

This model was able to achieve 91.2% accuracy in the diagnosis of these diseases from the d ata collected.

There were other models with less than 90% accuracy also used todiagnosespecific types of heart diseases.

Contd..

Cancer In 2012, reports of American cancer society said that more than 1.6 million newly diagnosed cases were found.

Hence, there was the need to develop a rapid and appropriate diagnosis for clinical management.

The pertinent information for diagnosis was collected from the advanced analytical methods like mass spectrometry and applied in the clinical diagnosis of breast and ovarian cancer.

Contd..

Artificial neural network is also used to develop in diagnosing the different types of brain tumours, lung carcinoma.

Ultimately, Artificial neural network was seen using the ground-level data that ranges from clinical data to results of biochemical assays and providing maximum diagnostic accuracy for different types of cancer.

DiabetesDiabetes has become a severe health risk issue in both developed and developing countries that reaching an estimate of 366 million diabetes cases globally.

Type ii diabetes is the standard type of this disease which is due to the improper cellular response to insulin which leads to hyperglycemia.

Contd..

The information of parameters like age, gender, weight and glucose level were collected and used as input data for building an Artificial neural network which could able to produce results with 90% accuracy.

Artificial neural networks are used to track the level of glucose as well asdiagnosing diabetes according to b iostatistical research for clinical trials.

ConclusionThe artificial neural network can be inferred as a powerful tool in clinical management of diseases with several advantages like the capability of processing a vast set of data, reducing the processing time, ability to produce optimized results with maximum accuracy.

Nevertheless, Artificial neural network can be used only as tool aiding in diagnosis done by the clinical physician, says b iostatistical CRO, who is responsible for critical evaluation of the results.

Pubrica helped to understand the role of ANN tool in the medical field.
