1. INTRODUCTION

   Global public health has faced substantial obstacles as a result of the Omicron version of the SARS-CoV-2 virus's emergence and rapid dissemination. [1]. Accurate and timely identification 0f viral variants is crucial f0r effective disease management and containment strategies. Computed Tomography (CT) scans have been widely utilized as a diagnostic tool for respiratory diseases, including COVID-19 [1,2]. In recent years, depth 1earning techneques, such as Convo1utional Neura1 Netw0rks (CNN) and Recurent Neura1 Netw0rks (RNN), have sh0wn grat potentia1 in medical image analysis. In this context, leveraging CNN and RNN for the prediction of the Omicron variant using CT

   scan images can provide valuable insights and aid in early detection and diagnosis.

   CT scan images provide detailed information about the structural changes in the lungs, offering an opportunity to identify characteristic patterns associated with different viral variants. CNNs, with their ability to automatically learn and extract meaningful features from images, have proven effective [3] in various medical imaging tasks. By applying CNNs to CT scan images, important spatial features related to the Omicron variant can be detected, aiding in accurate classification.

   However, CT scan images also contain temporal information that can provide additional insights into the progression and evolution of the viral infection. RNNs are specifically designed to capture sequential dependencies and temporal patterns, making them well-suited for analysing sequences of CT scan images. By incorporating RNNs into the prediction framework, the model can consider the sequential nature of the scans, enabling the detection of subtle changes and dynamic patterns associated with the Omicron variant over time.

   The integration of CNN and RNN architectures for the prediction of the Omicron variant using CT scan images holds significant promise. By leveraging both spatial and temporal information, these models can provide a comprehensive analysis that aids in accurate and timely identification of the viral variant. However, it is important to emphasize that these predictive models should not replace the expertise of medical professionals but should be utilized as complementary tools to support clinical decision-making.

   0ne of the most popular ways to diagnose pneumonia a11 around the wor1d is through chest radiography (X-ray) [4]. Th chest xray is a quick, inexpnsive, annd frequent1y emp1oed clinica1 meth0d. Cheap Xrays subject the patient to 1ess radeation than computd tomogrphy (CT) and magnatic resonace imaging (MRI). The po1ymerase chain reaction (PCR), which replicates specific DNA sequences in vitro, uses DNA polymerase.

   In this study, we aim to explore the effectiveness of CNN and RNN-based approaches for the prediction of the Omicron variant using CT scan images. We will investigate the ability of these models to extract spatial features from individual scans and capture temporal dynamics across multiple scans. Through an evaluation of their performance on a carefully curated dataset, we aim to provide insights into the potential of deep learning techniques in assisting with the

   early identification and diagnosis of the Omicron variant, ultimately contributing to more effective management of the COVID-19 pandemic.

2. LITERATURE SURVEY

   The COVID-19 pandemic, which affected the world in 2020, resulted in a significant number of infections and loss of human lives. The outbreak, caused by specific coronaviruses similar to SARS and MERS, led to severe respiratory symptoms and impacted various organs in addition to the respiratory system. Medical facilities, including intensive care units (ICUs), faced challenges due to overwhelming cases. In response, researchers turned to advanced technologies like RNN (Recurrent Neural Networks) for medical research and diagnostics, including the detection of diseases in remote endoscopy images, identification of malaria parasites, recognition of lung infections, and prognosis of various illnesses using X-ray imaging systems.

   Following the emergence of the Omicron variant in 2019, researchers worldwide engaged in extensive trial and error, research, and treatment efforts to understand and manage the new variant. Governments implemented measures such as quarantines, on1ine education, businesses ad trave1 restrictions to mitigate th spread 0f COVID-19. Real-time analysis and prediction models became crucial to guide public health responses and provide clear guidelines for combating the virus.

   To address the need for accurate predictions, the authors of a study utilized a combined CNN _LSTM (Convo1utional Neura1 Netw0rk L0ng Sh0rt-Trm Mem0ry) model with th time-series data set to predeict COVID-19 infections. Th CNN-LSTM encoder-decoder technique significantly improved the performance of the predictions. The analysis incorporated both the proposed RNN-based model and a CNN-based model with a modified version of LSTM to determine factors such as the death ratio, number of infecte patients, and recovered individuals.

   Researchers explored the innate and adaptive immune cells interact in th context of COVID-19 induction. They higpighted the socia1 and environmenta1 risks ass0ciated with infecti0us diseases and prop0sed various strategies, such as merging ribavirin and interferon-b together, and evaluating te effectiveness 0f different vaccine doses against variants like Omicron. In most cases, Convo1utional Neura1 Netw0rk, Recurrent Neura1 Netw0rks, and combined models incorporating deep learning techneques were found t0 be accurate and efficient in detecting and predicting COVID-19.

   In summary, researchers have been actively utilizing CNN and RNN models to understand and address the challenges posed by COVID-19, including the prediction of infections, identification of variants, and evaluation of treatment options. These advanced techniques offer valuable insights and have the potential to contribute significantly to combating the pandemic.

3. SYSTEM METHODOLOGY

   1. Existing System: CNN and RNN are two exce11ent techno1ogies that are used by academics for in-depth learning. Despite their short cmings, these methods are in fact wide1y used and produce excel11ent resu1ts.

      There are accessible strategies for superlative learning, such as the Recurrent Neural Network organisation. Problems with RNN statistics

   2. Proposed System: The following procedure was used in this study to collect data in a methodical manner. First, we compiled research from archives, journals, conferences, and te disciplines of digital humanities and computer science. Despite te fact that we were aware 0f several other 1ocations and these broad needs may be satisfied by industries like 1aw, security and surveil1ance, and document procesing, thus we fe1t 0ur se1ections were adequate to present the curent conversation on the subject at hand as a p1ace to start f0r the current discussion of there. 0ver the past six years, we have curatd a1l re1eases (inc1usive 0f 2O15-2O20) to the most recent on these websites. There were two factors involved in selecting 2015 as the starting year. On te 1 hand, recnt deve1opments is the application of neural networks or s0-ca1led depth 1earning have significant1y impr0ved m0dern AI.

      There are accessible deep learning techniques such as Extended Recurrent Neura1 Netw0rks (RNN) and others.

      Benefits of the ECNN algorithm:

      • Accuracy for f1oods

      • Time savings

      • brief working periods,

      • degrees of margina1 error

      • big data management

        The three stages of the proposed model are classification, dimension reduction and feature extraction, and CNN image pre-processing.

      • Pre-processing of the image: In the pre-processing step, the image is changed must satisfy the demands of the stage after that. While noise and other items in the image are blurred, the edges are sharpened filtered out. X-ray images are also altered in this case. A noise-reduction mechanism filter is present.

      • Dimens0n Reducti0n and Feature Extracti0n Stage: Te l0ca1 featurs ar revea1ed once the 400*400-pixel l0cal hill patern was f0und. The Haar wave transformation is employed to reduce this feature vector to a one-dimensional form because it is too huge to be utilised in the classification procedure.

      • Classification Stage: Classifying images is done through the technique of image classification. A categorization system is a database in one of the aforementioned categories where predefined patterns are examined to place the detected object in the appropriate class. Image recognition is a crucial and challenging task that is used in many applications.

   3. Input Dataset: On a 16,733 CT-scan images were collected in this dataset from the Kagg1e repository (source:

4. EXPERIMENTAL RESULTS

   Letting the picture data explore regions and portions that correspond to core assumptions is the central concept behind the system's design and implementation. such structure designs therefore represent the structure, components, moduli, insides, and problems of the fundamental performance. In terms of data collection, analysis, and definition of procedures and policies, there is some breadth and collaboration. The benefits of the application are taken into account when evaluating capabi1ites and implementations.

   Now that the system is put in place by particular needs, it also hopes to generate a sizeable degree.

   ECNN algorithm: The proposed strategy required CNN to enlarge in order to create all-inclusive ECNN(s), taking into account increased exactness, execution, and time complexity. The aforementioned algorithmic processes explain and list the methods that were uti1ised to try for a quick execution time while achieving high accuracy and a low error rate.

6. CONCLUSION

Recurrent neural networks (RNN) and convolutional neural networks (CNN) for te early detection and diagnosis of the Omicron variant utilizing CT scan images demonstrates remarkable potential. These models can efficiently evaluate and extract significant information from CT scans by utilizing the strength of deep learning algorithms, which helps to produce precise predictions of the Omicron variety. In the beginning of the prediction process, the CNN component is quite important. It has the ability to automatically recognize and learn pertinent patterns and structures within the CT scan images. The pooling layers enable dimensionality reduction and feature selection, while the convolutional layers aid in capturing local information like texture, edges, and forms. By effectively identifying patterns linked to the Omicron variation, the CNN is able to accurately classify CT scans thanks to this hierarchical feature extraction.

By identifying temporal dependencies and sequential patterns in the CT scan images, the RNN component improves the predictive powers even more. Recurrent layers enable the model to take into consideration contextual data from numerous scans, accounting for the evolution of the Omicron variation over time. The identification of minor changes and patterns that might not be visible in individual photos alone is made possible by this temporal modeling.
