Abstract The severe acute respiratory syndrome coronavirus, which is the source of the present deadly coronavirus epidemic, was discovered in Wuhan, China. Threats to human life have been created by this pandemic's effects. Covid 19 is a fatal virus that is fast spreading and has an impact on people's daily lives, health, and economies of nations. This sickness not only harmed a single nation; it also hadanimpact onthe entire world. Millions ofindividualshave been impacted by the outbreak, and the death toll has been rising alarmingly. Forecasting and careful analysis of the pattern of disease spread in such a setting might motivate the creation of better strategies and more effective decision making.
Key Words: COVID 19, CNN, VGG, Deep Learning, Lung CT Scan Images.
Artificialneuralnetworks,aclassofalgorithmsinspiredby thestructureandoperationofthebrain,arethefocusofthe machine learning discipline known as deep learning. Although they can also include propositional formulas or latent variables organised layer wise in deep generative models like the nodes in deep belief networks and deep Boltzmann machines, the majority of contemporary deep learning models are based on artificial neural networks, specifically convolutional neural networks (CNN). Deep learningmodelsaresometimesreferredtoasdeepneural networksbecausethemajorityofdeeplearningtechniques useneuralnetworktopologies.Thenumberofhiddenlayers in the neural network is typically indicated by the term "deep."

Before the survey is conducted,itmustbeplanned.Theprojectheavilydepends on the literature review. It serves as a starting point for project ideas that are then developed into concepts and, ultimately,theories.
The study by Yujin Oh, Sangjoon Park, and Jong Chul Ye, "Deep Learning COVID 19 Features on CXR Using Limited Training Data Sets,"[1] illustrates how deep learning approach on chest X ray for Covid 19 classification have been actively researched. It is challenging to compile a systematicsetofchestX raydatafordeepneuralnetwork training.Theysuggestedapatch basedconvolutionalneural networktechniquewithamanageablenumberoftrainable parametersforCovid 19diagnosticstosolvethisissue.The proposedmethodwasinspiredbystatisticalanalysisofthe potential imaging biomarkers of the chest radiographs.

ApresentationofANN basedtechniquesthatcanbe used for big data analysis is made in the publication "Artificial Intelligence and COVID 19 Deep Learning ApproachesforDiagnosisandTreatment"[2]byMohammad JamshidiandAliLalbakhsh.IthasbeensuggestedthatANN based strategies could be employed in addition to conventionalonestokeeppatientsinvolved.TheCovid 19 registry emphasises clinical factors and cardiovascular complications because it helps to identify the pattern of cardiovascularcomplications,advancethedevelopmentofa risk model for cardiac complications, and help identify or predict the response to various treatment modalities. However,thestudy'smainlimitationwastheuseofasmall numberofdata,whichledtounderfitoroverfitissues. .A deeplearning basedmethodwaspresentedbyGhoshaland Tucker to quantify the degree of uncertainty and interpretability in coronavirus detection. The authors discoveredthatthecorrelationbetweenpredictionaccuracy andpredictionuncertaintyisquitestrongusingaBayesian convolutional neural network using publically available Covid 19CXRpictures.UsingthepretrainedVGG 16model, the performance results show an increase in detection accuracy from 85.2 percent to 92.9 percent. In order to betterunderstandtheoutcomesproducedbytheproposed approach, they have also demonstrated the model's interpretabilitybycreatingsaliencymaps.

AnewCOVID 19patientsdetectionstrategy(CPDS) based on hybrid feature selection and improved KNN classifier is described in the research.

TheCXRimagesarecategorisedasnormalorabnormalin the first decision tree. The third tree performs the same functionforCOVID 19whereasthesecondtreeidentifiesthe aberrantimagesthatcontainsymptomsoftuberculosis.For each step in this study, training data were taken from an acceptabledatagroup;nevertheless,trainingdatashouldbe verifiedwithpathologicaldata.Theconclusionsofthemodel areunreliablewithouttheuseofpathologicallyverifieddata. New pathology information was thus necessary for the prediction of new instances. Third, a deep learning model was expanded with more training data using simple techniques like horizontal flipping, rotations, and shifts. There are various data augmentation methodologies for picturedata.Theperformanceoftheobtainedmodel may havebeenenhancedbytakingintoaccountimageprocessing techniques like stochastic region sharpening, elastic transforms,randomlyerasingpatches,andmanyothersto augmentdata.

these strategies can be used to make speedy diagnostic decisions for COVID 19. This study lends credence to the notionthatDLalgorithmsofferaviablemeansofenhancing healthcare and the efficacy of diagnostic and therapeutic operations.
Since COVID 19 DL diagnostic models must be trained on sizable, heterogeneous datasets to fully exploit theavailabledataspace,developersmustbecarefultoavoid overfitting and to maximise the generalizability and usefulnessofCOVID 19DLdiagnosticmodels.DLisoneof the most powerful computing tools for diagnosing pneumonia.
