Deep Convolutional Generative Adversarial Networks for Automated Segmentation and Detection of Lung Adenocarcinoma Using Red Deer Optimization Algorithm

The diagnosis of early-stage lung cancer can be challenging due to several factors. Firstly, the asymptomatic nature of the disease means that it may not present any noticeable symptoms until it has progressed to later stages. Additionally, the use of computed tomography, which can be expensive and involves repetitive radiation exposure, can further complicate the diagnostic process. Even specialists may encounter difficulties when examining lung CT imagery to identify pulmonary nodules, particularly in the case of cell lung adenocarcinoma lesions. This paper suggests a unique deep learning-based Deep Convolutional Generative Adversarial Networks (DCGAN) model for lung cancer classification. The dataset utilized for the experimental purpose is accessed from the LUNA16 challenge database. This comprises 888 CT scans of the lungs. These images are initially segmented using Quick-CapsNet (QCN) model and applied with Red Deer Optimization (RDO) algorithm to extract the optimized features. Furthermore, the categorization between benign and malignant tumors is carried out using the DC-GAN model. The pulmonary nodule detection accuracy of the proposed model is 98.65%, indicating early-stage lung cancer. It is discovered to be superior to other existing techniques, such as sophisticated deep learning, straightforward machine learning, and hybrid methods applied to lung CT scans for nodule diagnosis. According to experimental findings, the suggested way can significantly help radiologists spot early lung cancer and facilitate prompt patient management.


Introduction
The number of lung cancer patients globally has increased, and the recurrence rate has gone up year after year due to the worsening of the environment brought on by more severe air pollution and variables like tobacco consumption and environmental toxins [33].One of the malignancies with the most excellent fatality rates today is lung adenocarcinoma.Concern has grown over correctly identifying lung disease and stopping its occurrence and progression [18].Most lung nodules are harmless, but some may be early signs of cancer.Lung nodules are abnormal growths within the lung that can either be either cancerous or benign [6].According to recent studies, only 22% of lung cancer patients survive for at least five years.Early diagnosis can significantly increase lung cancer survival rate.Noncancerous and not propagating to other body areas are benign lesions [21].By 2034, the World Health Organization (WHO) predicts that 25% of fatalities will be attributable to lung adenocarcinoma.
Computed Tomography, the most popular imaging method in healthcare, is frequently used to find lung malignancies.High-density precision in CT images allows for creating contrast pictures even for parts with minute density variations, such as mucous membranes in humans.Yet, the volume of medical imaging data is expanding quickly due to the ongoing advancement of imaging technology and the corresponding rise in clinical needs, particularly the introduction of elevated CT equipment.According to statistics [25], 92% of the information stored in hospitals is in the form of medical images, and as clinical technology progresses, this percentage is growing by 32% annually.At the same time, just 8% more qualified imaging specialist clinicians have been hired [13].
A whole lung CT scan session typically comprises around 125 to 275 pictures.Radiologists' diagnostic work has become progressively more difficult, demanding their psychological and physiological stamina [27].It demonstrates how reading time for a single scan sequence increases while reading accuracy decreases.After looking directly at CT pictures for a while, human eyes will likely grow tired, resulting in muffed observations and erroneous interpretations.The research team at Johns Hopkins University in the United States conducted similar research.It concluded that there is a 30-40 percent chance that a single imaging specialist will overlook the dark spot of clinically relevant lung nodules while diagnosing a chest CT [9].Thus, doctors must use computers to aid in reading and diagnosis, enhancing the speed and precision of the latter.
Computer-aided diagnostic (CAD) technology has made significant strides recently due to the rapid growth of computer infrastructure and programming technologies.It has also gradually proven its therapeutic relevance in prognosis.Professional clinical diagnosis specialists use CAD software more frequently to aid in evaluation.The hospital's workflow eventually incorporates CAD software as a "serial device" [4].Through the use of radiographic images, imagery analysis methods, and computerized analysis capabilities, physicians' assessment of individuals is enhanced to be more effective and precise.
Deep learning has tremendous potential for classifying cancerous and non-malignant cancer nodules since it may minimize the number of scans necessary to determine whether a nodule is benign or malignant [12].Detecting harmless and cancerous modules using deep learning approaches has shown encouraging results.The most advanced CAD system uses deep learning models to characterize lung nodules and determine whether they are problematic [28].These systems also identify a nodule's kind, determining whether it is harmful or innocuous.
Even though CAD systems show noticeably more excellent performance in lesion diagnosis, few studies take a regular physicians' workflow into account [23].Clinically, physicians locate the suspicious prospects for additional evaluation by evaluating the Maximal Prediction Strength (MPS) images [30].MPS enables higher spectral 3-D volumetric translation to the direction of extrapolation, improving tumor identification.Deep learning techniques can detect pulmonary nodules spontaneously since MPS images retain sensitivity data and are not boundary reliant [16].Thus, this study proposes a deep learning-based approach incorporating segmentation and optimization techniques for lung cancer detection.
The main contributions of this work are, 2 To efficiently segment the lung CT images using the Quick-CapsNet model and extract the most optimal features from the segmented images using the Red Deer Optimization algorithm.
3 To effectively demonstrate the suggested model's performance excellence against existing literature on lung cancer identification and categorization.
The remainder of this paper is organized as follows.
Section 2 elaborates on the recent works in lung cancer research using deep learning approaches.Section 3 describes the proposed methodology to efficiently detect lung cancer from CT images using segmentation, optimization, and classification techniques.Section 4 presents the results of applying the proposed optimized deep learning model to the LUNA16 dataset.Section 5 discusses the challenges and research directions in this arena exclusively.Section 6 concludes the present research.

Related Works
This section discusses the various state-of-the-art methods in lung adenocarcinoma detection employing deep learning techniques.Authors in [5] introduced the three-dimensional convolutional neural networks-based unsupervised learning approach for lung cancer diagnosis.This statistical classification approach enhances pulmonary nodule transparency using the steepest descent non-linear activation [7].
The proposed detection technique is evaluated and contrasted with an existing two-dimensional convolutional neural network learning model using the LUNA dataset.As only 10% of the training database was used for testing, the suggested model is unsuccessful [31].
Researchers in [24] developed a supervised prediction algorithm to identify early adenocarcinoma in lung cancer patients.The suggested model was verified using real-time non-cancerous patient data collected from impacted individuals in the initial phases.The database contains 315 data phases that have been recorded [19].The created model, a VGG network-based training classifier, has an unsatisfactory prediction rate of 74 percent Area under the curve.The VGG CNN model's flaw is that it needs to be preprocessed for CT semantic segmentation and image filtering, which lowers the prediction rate [32].
The most recent methods for classifying and detecting lung cancer were evaluated in [8].The most recent tumor segmentation identification, placement, and classifications are associated with algorithmic approaches to supervised learning like Support Vector Machine, K-nearest neighbors, and Convolutional neural networks and standard datasets like LIDC-ID-RI, LUNA 16 as well as Super Bowl Dataset 2016 considered to be the most common and typical baseline CT data for illness diagnosis [17].To identify patients with aggressive or innocuous lung cancer, authors in [1,14] presented the DenseNet model, a categorical predictor built on a dense CNN model.The researchers used a dataset of 204 lung scans [10], with 75% of the images used for training and 25% for validation and prediction.Test results showed that the suggested procedure had an accuracy of 91.65% [20].
After examining hyperspectral imagery, five different types of pulmonary and colorectal cells were identified using a grading system created by the scientists [2].According to the results, the suggested model can successfully identify diseased tissue up to 93.33 percent of the time.According to [3], computer-assisted examinations can be used to collect, evaluate, and integrate multitype intertwined features to determine the status of a Missense mutation.Thus, it is observed from the literature review that though deep learning is applied to detect lung cancer in various research, there still is a lot of scopes to perform the classification with more accuracy and resilience.Therefore, the proposed study also applies a deep learning model for classifying lung CT images using segmentation and optimization techniques.

Proposed Methodology
This section discusses the proposed methodology for lung adenocarcinoma detection using Quick-Caps-Net, Red deer Optimization algorithm, and Deep Convolutional GAN model.A detailed description of these models concerning the suggested approach is presented.The workflow of the proposed system is depicted in Figure 1.
Today medical arena depends on artificial intelligence for predicting the highly dangerous diseases in the human life.This research use deep learning and heuristic method to predict the lung adenocarcinoma detection.First, the dataset is collected and segmented using Quick-CapsNet algorithm.Segmented images are used for extracting the features using red deer optimization algorithm.Finally, extracted features

Quick-CapsNet (QCN)
In this work, QCN is employed to perform the segmentation process, an extension of the Capsule Networks.The architecture of QCN is elaborated on in this section.In conventional Capsule Networks, two convolutional layers that extract the input image's basic features are the network's first layers.8D vectors are created by reshaping the second convolutional layer's output.The term "Principal Capsules" refers to these 8D vectors.Once the initial layer of capsules is produced, there may be several further layers.
In the convolutional layer of Quick-CapsNet, the kernel size of 9 refers to the size of the filter or window that moves over the input image to perform convolution.Specifically, a 9x9 kernel is used to extract features from the input image, which are then used as input to subsequent layers in the network.The choice of kernel size can affect the performance of the network, as it determines the amount of spatial information that is captured from the input image.A larger kernel size can capture more global features, while a smaller kernel size can capture more local features.
In the QCN architecture shown in Figure 2, a Fully-Connected (FC) layer replaces the second convolution layer in the capsule network.This equates roughly to incorporating the participation of each neuron in the convolutional layer's output feature map.The FC layer describes all the neurons in the preceding layer.An FC layer is supplied with the output of the first convolutional layer.The Principal Capsules, which are the input for the route optimization algorithm, are constructed from the FC layer's output by reconfiguring it.The result of the segmentation is shown in Figure 3.

Red Deer Optimization Algorithm (RDOA)
RDOA is used in the proposed work to select the optimized features before implementing the classification technique.The RDOA starts with a preliminary population of individuals opposite Red deers, just like other meta-heuristics.The population is divided into hinds and male red deers, with a chosen few of the top Red deers.The male red deer needs to roar first.They are split into two groups according to the intensity of a screaming phase, namely masters and stags.Then, each harem's masters and stags engage in joint combat to claim their respective harems.Moreover, masters create harems.The ability of the masters to scream and the battle is directly correlated with the number of hinds in harems.As a result, in harems, masters mate with various hinds.Figure 4 presents the steps in the Red deer Optimization Algorithm.

Deep Convolutional GAN (DCGAN)
A Differentiator(D) and a Producer(P) are parts of GAN's primary structure.Real samples are generated using the producer, and real samples and fraudulent samples are distinguished by the differentiator.In order to produce a created false sample, the generator translates an additive noise field (Z) to a new multidimensional data structure.To perform classification and determine the likelihood that the testing sample (S) is a genuine sample, the differentiator is used.
To create a false sample during training, the producer attempts to learn the data distribution of the real sample, while the differentiator aims to separate the resulting false sample from the real sample.
The deconvolution layer creatively replaced the fully connected layer of the producer in the basic GAN network, strengthening the neural network structure in the GAN model and attaining good performance in image creation tasks.As seen in Figure 4, the DCGAN uses CNN's strong feature extraction capabilities to enhance the generative network's capacity for learning.The layer's producer can learn steadily with the help of Regularization, allowing the model to understand better the distribution of the data sampled and more steadily provide elevated examples.

Dataset Description
The divergent scans in the LUNA16 dataset, which is a subcategory of the LIDC-IDRI dataset, are screened using several parameters.A substantial fraction should be used because pulmonary nodules might be minuscule.Scan results with a layer depth of more than 2.5 mm were thus disregarded.Moreover, images that had uneven layer separation or incomplete layers were dismissed.This resulted in 888 CT scans and 36,378 radiologists' observations.For lung cancer screening techniques, only the observations in this dataset labeled as nodules under 3 mm are considered significant [2].Nodules discovered by various readers that were closer together than the product of their radii were combined.In this instance, the integrated annotations' locations and dimensions were normalized.As a result, a collection of 777, 2290, 1186, and 1602 nodules have, respectively, been evaluated by four radiologists.The dataset used in the experimentation can be accessed via the given link.https://www.kaggle.com/datasets/avc0706/luna16

1000 initial samples were used in the proposed lung adenocarcinoma detection experiment.The data set was then extended using data augmentation to yield 10,000 samples, split into the training (80%) and the test set (20%).Two data augmentation techniques were applied to the dataset to enlarge it for trial purposes.First, the attempt to alter the axis of the images was executed by flipping it.Secondly, image rotation was incorporated by generating an angle between 0 and 180 in an arbitrary fashion.The model parameters are set as per the details in Table 2.    Computerized imagery fabrication, such as creating interaction networks, is another viable approach.Insufficient data will inevitably impact prediction accuracy and consistency.Consequently, one of the directions for future study is to increase the accuracy rate utilizing minimal supervision, transfer learning, and inter-learning with minimal labeled data.

Conclusion
In this research, a novel deep-learning model for lung adenocarcinoma detection and categorization has been proposed.The proposed methodology primarily involved image segmentation, feature selection, and classification.The Quick-CapsNet model is incorporated to segment the images and feed them further for the feature selection process.Its ability to segment images quickly and accurately compared to other segmentation techniques.This is achieved by reducing the number of computations required for the segmentation process, making it computationally efficient.The red deer Optimization algorithm extracts optimized features from the segmented images before forwarding them to the classification phase.The segmented image can be represented as a matrix of pixels, where each pixel has a certain value that corresponds to its intensity or color.RDO can then be used to select the most relevant features from this matrix by optimizing an objective function.The third stage of lung cancer categorization is performed using the Deep Convolutional GAN model, which successfully classifies benign and malignant lesions with an accuracy of 98.65%.The proposed model performance is contrasted against several traditional deep learning models and existing optimization-classification model combinations in the literature to prove the performance precedence of the suggested work.One of the downsides of the present research is that it has been applied to a smaller dataset.In future research, artificial intelligence solutions can be leveraged for lung cancer prognosis to relatively larger datasets comprising CT images.

Further, the performance of the proposed model is compared with the conventional deep learning models and few of the existing works in the literature to prove the performance superiority of the suggested model for the diagnosis of lung adenocarcinoma Deep learning models such as Deep Neural Networks (DNN), Convolutional Neural Networks (CNN), Recurrent Neural Networks (RNN), and Generative Adversarial Networks (GAN) are considered for the performance comparison with the proposed model initially.It is observed that DNN produced an accuracy of 83.56% for the lung cancer detection problem when applied to the LUNA-16 dataset.Precision, Recall, and F1 score values produced by this model are 82.45%,81.75%, and 83.26%, respectively.The next model, CNN, made a better accuracy of 87.48% than DNN.The other performance metric values were also improved for the CNN model compared to the DNN

Table 2
Model Parameter Settings The issue of surpassing the upper limit of the visual memory in the initial step of feature extraction can be avoided by partitioning the image information into 32 blocks, each of size 128.This increases the training data and prevents the input of the whole image.
Frame recognition is trained using the layer learning method since direct resizing of the image sequence would surely destroy a great deal of specific information and the problem of distorted boundaries.Frame retraining, the approach used, is comparable to the sliding window during feature extraction.

Existing models Vs Proposed model Performance Comparison Existing Vs Proposed the proposed model.GAN produced an accuracy level of 92.5% higher than the other Deep learning models applied to the lung cancer dataset.However, it is lower than the accuracy of cancer detection exhibited by the proposed DCGAN model, which is 98.65%.Deep learning approaches such as Quick-CapsNet and DCGAN have shown successful segmentation as well as classification results respectively.Unfortunately, there are still a lot of issues with lung cancer detection using deep learning algorithms.Secondly, because there are not any established processes for acquiring medical images, clinicians have not completely embraced deep learning techniques for routine clinical practice.It might be reduced by combining the procurement processes.Second, deep learning approaches often need many well-labeled medical images to finish training objectives.Even when done by professional physicians, collecting a sizable labeled image dataset is expensive and time-consuming.The lack of labeled data can be overcome using a variety of techniques.For instance, transfer learning may address the training issue with limited samples.
