The back propagation algorithm is most popular algorithm in feed forward neural network with the multi-layer. It measures the output error and calculates the gradient of the error and adjusting the ANN weight moving along the descending gradient direction. Back propagation is used to learn and store by mapping relations of input- output model. A genetic algorithm is having a random probability distribution or pattern that may be analyses statistically but may not be predicted precisely. Genetic algorithm is an iterative procedure that generates new population for individual from the old one. In my paper I am proposing to implement the back propagation algorithm and genetic algorithm to compare the output accuracy percent for medical diagnosis on various chest diseases (Asthme, tuberculosis, lung cancer, pneumonia).

Classification Of Iris Plant Using Feedforward Neural Networkirjes
The classification and recognition of type on the basis of individual features and behaviors constitute
a preliminary measure and is an important target in the behavioral sciences. Current statistical methods do not
always yield satisfactory answers. A Feed Forward Artificial Neural Network is the computer model inspired by
the structure of the Human Brain. It views as in the set of artificial nerve cells that are interconnected with the
other neurons. The primary aim of this paper is to demonstrate the process of developing the Artificial Neural
network based classifier which classifies the Iris database. The problem concerns the identification of Iris plant
species on the basis of plant attribute measurements. This paper is related to the use of feed forward neural
networks towards the identification of iris plants on the basis of the following measurements: sepal length, sepal
width, petal length, and petal width. Using this data set a Neural Network (NN) is used for the classification of
iris data set. The EBPA is used for training of this ANN. The results of simulations illustrate the effectiveness of

Cao nicolau-mc dermott-learning-neural-cybernetics-2018-preprintNam Le
This paper proposes using latent representation models, specifically autoencoders (AEs) and variational autoencoders (VAEs), to improve network anomaly detection. The models are trained on only normal data and introduce regularizers that compress normal data into a tight region around the origin in the latent space, while anomalies will have representations further away. This new latent feature space is then used as input to one-class classifiers to detect anomalies. The goal is for the models to perform well even with limited training data and be insensitive to hyperparameter settings, in order to address challenges of network anomaly detection like lack of labeled anomaly data and high dimensionality.

A Comparative Analysis of Feature Selection Methods for Clustering DNA SequencesCSCJournals
Large-scale analysis of genome sequences is in progress around the world, the major application of which is to establish the evolutionary relationship among the species using phylogenetic trees. Hierarchical agglomerative algorithms can be used to generate such phylogenetic trees given the distance matrix representing the dissimilarity among the species. ClustalW and Muscle are two general purpose programs that generates distance matrix from the input DNA or protein sequences. The limitation of these programs is that they are based on Smith-Waterman algorithm which uses dynamic programming for doing the pair-wise alignment. This is an extremely time consuming process and the existing systems may even fail to work for larger input data set. To overcome this limitation, we have used the frequency of codons usage as an approximation to find dissimilarity among species. The proposed technique further reduces the complexity by extracting only the significant features of the species from the mtDNA sequences using the techniques like frequent codons, codons with maximum range value or PCA technique. We have observed that the proposed system produces nearly accurate results in a significantly reduced running time.

A clonal based algorithm for the reconstruction of genetic network using s sy...eSAT Journals
Abstract Motivation: Gene regulatory network is the network based approach to represent the interactions between genes. DNA microarray is the most widely used technology for extracting the relationships between thousands of genes simultaneously. Gene microarray experiment provides the gene expression data for a particular condition and varying time periods. The expression of a particular gene depends upon the biological conditions and other genes. In this paper, we propose a new method for the analysis of microarray data. The proposed method makes use of S-system, which is a well-accepted model for the gene regulatory network reconstruction. Since the problem has multiple solutions, we have to identify an optimized solution. Evolutionary algorithms have been used to solve such problems. Though there are a number of attempts already been carried out by various researchers, the solutions are still not that satisfactory with respect to the time taken and the degree of accuracy achieved. Therefore, there is a need of huge amount further work in this topic for achieving solutions with improved performances. Results: In this work, we have proposed Clonal selection algorithm for identifying optimal gene regulatory network. The approach is tested on the real life data: SOS Ecoli DNA repairing gene expression data. It is observed that the proposed algorithm converges much faster and provides better results than the existing algorithms. Index Terms: Microarray analysis, Evolutionary Algorithm, Artificial Immune System, S-system, Gene Regulatory Network, SOS Ecoli DNA repairing, Clonal Selection Algorithm.

ABSTRACT
The back propagation algorithm is most popular algorithm in feed forward neural network with the multi-layer.
It measures the output error and calculates the gradient of the error and adjusting the ANN weight moving along
the descending gradient direction. Back propagation is used to learn and store by mapping relations of input-
output model. A genetic algorithm is having a random probability distribution or pattern that may be analyses
statistically but may not be predicted precisely. Genetic algorithm is an iterative procedure that generates new
population for individual from the old one. In my paper I am proposing to implement the back propagation
algorithm and genetic algorithm to compare the output accuracy percent for medical diagnosis on various chest
diseases (Asthme, tuberculosis, lung cancer, pneumonia).
Keywords: - Artificial neural network, back propagation algorithm, chest diseases, genetic algorithm, medical
diagnosis.
I. Introduction
1.1 Hybrid System
Hybrid system is a technology which is entwined
with two different technologies to give a better
solution for the application result. One technology is
not enough to solve a problem then it use another
technology to solve a problem.
As our project title is showing that we are using
two different technologies that are artificial neural
network and the genetic algorithm. These two
technologies belong to two different fields which are
entwined/embedded which are called hybrid
technology. Back propagation is the most popular in
learning techniques with the multi-layer network. In
these techniques the information flows from the
direction of the input layer towards output layer. The
learning is achieved by adjusting the connection
weight in artificial neural network iteratively so that
trained. The number of iteration of the training
algorithm and the convergence time will vary
depending diagnosis problem their various data set.
Genetic algorithm is a computational model which is
a stochastic general search method. It proceeds in an
iterative way by generating new chromosomes to get
the best solution and work on the best fit probability.
In hybrid system the artificial neural network
(ANN) is used to create network and the genetic
algorithm is used to get the best fit probability to
reduce the number of iteration by adjusting the
weight.
1.2 About Chest Disease
The chest is the most important part of the body
for function the respiratory system. Now a day’s
millions of people are suffering with a chest disease
in the world.
Acute bronchitis is the type of bronchitis by
adding the cold and flu to an inflammation of the
bronchial tube (bronchial tube is that which passes
the air to lung) bronchitis converted into acute
bronchitis. It is spread through the cough people or
with the unwashed hands shortness of breath,
wheezing and chest tightness this are also a
symptoms of acute bronchitis.
ARDS (Acute Respiratory Distress System is
occurred in the lungs when the oxygen level is low in
the blood stream. It caused by direct or indirect injury
to the lungs. These injuries can be breathing vomit
into the lungs, inhaling chemicals lung transplant etc.
Asbestosis is causes the lung tissues and the
chest wall get thicken and harden. By harden it
makes it hard to breathe and for oxygen to get into
the blood.
Asthma is a chronic disease which is occurred
when the airway is swollen. The airway is narrowed
and it difficult to move the air in and out of the lungs.
Asthma can be inherited by genetic.
II. Neural Network
An artificial neural network is an information
processing paradigm that is inspired by the way
human brain process information. The neural network
applications are pattern recognition, forecasting
clustering data classification, medical, biological etc.
artificial neural network is an interconnected groups
of artificial neurons that user a mathematical model
or computational modal for information processing
based on a connectionist approach to computation.

element which displays the complexity in global
behavior, which determined by the connections
between the processing neurons and neurons
parameters. It is made of interconnecting artificial
neurons which may share some properties of
biological neural networks. Artificial neural network
is used to solve the real world problems. Artificial
neural networks provide a tool to help doctors to
analyze and make sense of complex clinical data of
medical applications.

2.3.1.2 Feed backward neural network
2.3.1.1 FEED FORWARD NEURAL NETWORK
Fig 2
The construction of the neural network involves
three different layers with feed forward architecture.
In this network the input layer contains the set of
input neurons, which accept the elements of input
feature vectors. The input neurons are fully
connected to the hidden layer neurons and the hidden
layer neurons are fully connected with the output
layer neurons the output layer sends the response of
neural network to the activation which is applied to
the input layer. The information given to a neural
network is propagated layer by layer from input layer
to output layer through one or more hidden layers.

III. BACK PROPAGATION
ALGORITHM
The artificial neural network has been trained by
exposing it to sets existing data where the outcome is
known. Multi layer networks use a variety of learning
techniques; the most popular is back propagation
algorithm. It is one of the most effective approaches
to machine learning algorithm developed by david
ruuelhart and Robert McLelland(1994). Information
flows from the direction of the input layer towards
the output layer. A network is trained rather than
programmed. Learning in artificial neural networks is
typically accomplished using examples. This is also
called “training” in artificial neural networks because
the learning is achieved by adjusting the connection
weights in artificial neural networks iteratively so
that trained. The number of iterations of the training
algorithm and the convergence time will vary
depending on the weight initialization. After
repeating this process for a sufficiently large number
of training cycles the network will usually techniques
are divided into supervised, unsupervised and
reinforcement learning.
3.1 Algorithm
Step 1:- first apply the inputs to the network and
calculate for output. The initial output can be
anything as the initial weights were random numbers.

Step 2:- the error for neuron B.
ErrorB=output(1-outputB)(targetB-outputB)
where output(1-output) is sigmoid function
Step 3:- change the weight
W+AB=WAB+(ErrorBxoutputA)
Where W+AB are new weight
WAB are initial weight
Step 4:- calculate the errors for the hidden layer
neurons. For hidden layer we can’t calculate error
directly because we don’t have a target value. By
using back propagation from output layer to hidden
layer by taking the error from the output neurons and
back tracked through the weights to find hidden layer
errors
ErrorA=output(1-outputA)(ErrorBWAB+ErrorC

Step 5:- after getting error for the hidden layer
neurons goto step 3 to change the hidden layer
weights. Repeat this steps to get trained network of
any number of layers
IV. GENETIC ALGORITHM
Genetic algorithm is a computational model
which is having a random probability distribution or
pattern that may be analysed statistically but may not
be predicted precisely general search method. To
generate new population it proceeds in an iterative
manner which is different from the old population.
Changes occur during reproduction. The
chromosomes from the parents exchange randomly
by a process called crossover. A rarer process called
mutation also changes some traits. Chromosome is an
array of bits or characters. Gene is a single bit or a set
of bits. Fitness is actual solution for evaluation.
4.1 Algorithm
Step 1:- generate random chromosomes of n
population.
Step 2:- the fitness of each chromosome x is
evaluated with f(x).
Step 3:- create new population repeat following steps
upto new population creation is completed.
a. select two best fit parent chromosomes
from a population.
b. crossover the parents to form new offspring.
The same offspring is found it meanse the
no crossover was performed.
c. mutation probability mutate new offspring at
each locus.
d. place new offspring in the new population.
Step 4:- replace generated new population with the
old population.
Step 5:- if the end condition is satisfied, return the
best solution in current population.
Step 6:- goto step 2.
V. HYBRID ALGORITHM
The good properties of two different technologies by
applying them to problems to solve efficiently this
are exploit by the hybrid algorithm. Hybridization of
different algorithms has led to creation of a trend
known as soft computing. In my project I am using
the neural network and genetic algorithm. Where the
neural network have ability to adapt to circumstances
and learn from the past experience. Genetic algorithm
is a systemize and random search and genetic
algorithm is inspired by biological evolution to reach
optimum characteristics. These technologies have
advantages and disadvantages. By hybridization of
these two technologies to overcome the weaknesses
of one with strength of other. How this two
algorithms are hybridized are shown in following
algorithm
5.1 Algorithm
STEP 1: configure the network l-m-n is taken
Where l= no of input of the neurons
m= no of hidden of the neurons
n= no of output of the neurons
STEP 2: the no of weights that the network l-m-n has
calculated by using the following formula
w= (l+n)*m
STEP 3: assume number of digits in weight are d
(where the d is the real number) which is
find by s=d*w (where s is the string)
STEP 4: choose population size p i.e. chromosomes
Ci
STEP 5: for each chromosome Ci
where i=1,2,3………p
{
Extract weight:- Wi’ form Ci Where Wi’ is
kept as the fixed weight, train the BPN for
the N input instances.
Calculate error:- Ei for each of the input
instances using the formula below
Ei = ∑j (Tji – Oji )2
where Oi is the output
vector calculated by BPN.
Find the root mean square E of the errors
Ei where i=1,2,3…….N
I.e. E= ((∑i Ei)/N)1/2
Calculate the fitness:-Value Fi for each of
the individual string of the population as Fi
=1/E
}
STEP 6: Output Fi for each Ci,
where i=1,2,……………….p

7.1 Description of result
User or doctor will select the symptoms by
selecting the checkbox. This selected checkbox are
taken as input symptoms. Some diseases are listed as
per the selection of symptoms in a list box which
shows the possibility of suffering by the patient.
From this list the highly found disease in a patient
body is listed in below given list box. As shown in a
result 1 screen shot we have selected 5 symptoms and
13 diseases are possible to be suffered but the highly
look like diseases are 2 of them. In this way we have
shown some more result to understand more clearly
how the results are changed depending on symptoms.
VIII. Conclusion
We have studied how the hybrid system is used
for medical diagnosis in chest disease. In this
software we are using Symptoms as an input which is
converted into value. These values and the extracted
weights (randomly selected values) are used to
calculate an activation function. To get the result as a
output we get the diseases. Scope of this software is
to add the test report with the symptoms as inputs.
