To fully utilize the potential of solar energy and effectively operate solar energy systems, it is vital to know solar radiation values. Modeling solar radiation data with high variability is a complex problem, and nonlinear methods are needed. This study proposes a hybrid model using CNN and LSTM architectures for solar radiation prediction. The performance and applicability of the proposed model are examined by comparing it with ARIMA statistical method and different machine learning methods such as Random Forest, Decision Tree and K-Nearest Neighbor. The study used hourly solar radiation values measured with a pyranometer on the Afyon Kocatepe University campus. As a result of the experimental studies, the CNNLSTM model is the most successful model in terms of RMSE, MAE, MAPE and r² evaluation criteria, achieving 16.92%, 17.25%, 17.24%, 22.89% more successful results than the Decision Trees model, which produced the most unsuccessful predictions, respectively.

Objective: Alternative splicing, the process of generating diverse protein isoforms by combining genes in various ways during RNA processing, is a crucial mechanism in cellular function. This study aims to identify the model with the highest accuracy in detecting alternative splicing regions. Material and Methods: Simulations were executed in Python with sample sizes ranging from 25 to 200. Genetic datasets maintained even distributions of A, C, G, and T nucleotides. Splicing regions were defined as GTAGC, GTAGT, GTAGA, and GTCGA, with 10,000 repetitions of the simulation. To prevent overfitting, 67.5% of the data served as the training set, 10% as the test set, and 22.5% as the validation set for support vector machines, random forest (RF), long short-term memory (LSTM), and deep neural network (DNN) methods. Model performance was assessed using prediction metrics. R programming language and computations were conducted on a Unix system. Results: Increasing the sample size correlated with enhanced model performance, notably for DNN and LSTM models. The LSTM model consistently demonstrated superior F1-score, specificity, and sensitivity compared to other models. The RF model exhibited effective performance, particularly with larger sample sizes. Conclusion: This study underscores the effectiveness of machine learning and deep learning models in identifying alternative splicing events. The findings emphasize the importance of considering model choice and sample size in optimizing the accuracy of alternative splicing region detection during RNA processing studies.

In this study, it is aimed to produce meaningful words in accordance with character-based Turkish grammar rules by using encoder-decoder and attention architecture, which are deep learning algorithms. The results of the developed model are compared with the results of LSTM and GRU models, which are other deep learning algorithms. It is seen that the language models created with LSTM and GRU models give similar results at 100 and 200 epoch values and at different threshold values of the temperature sampling method. Among these models, the GRU model gives the highest success value with 88.40% at 200 epochs and 0.5 temperature threshold value. The encoder-decoder and attention language model developed for this study gives the highest success value of 91.90% at 100 and 200 epoch values and at different threshold values of the temperature sampling method at 200 epoch and 0.5 temperature threshold value. At the end of the experiments, the encoder-decoder and attention architecture model showed an average of 2.83% more success than the LSTM model and an average of 0.19% more success than the GRU model.

This study aims to investigate the effectiveness of deep learning and machine learning algorithms on consumer price index (CPI) forecasting using monthly consumer price index data and 5 independent variables (employment rate, average dollar rate, producer price index, Brent oil prices, and consumer loan interest rate) for the period January 2005–June 2023. To this end, different deep learning and machine learning models such as Long and Short Term Memory (LSTM), Gated Recurrent Unit (GRU), Random Forest, Artificial Neural Network, and K-Nearest Neighbors are used for CPI forecasting, and their forecasting performance is evaluated with RMSE, MSE, MAE, MAPE, and R² error statistics. The results show that the GRU model outperforms the LSTM, Random Forest, Neural Network, and K-Nearest Neighbors models. The GRU model outperformed the other four models in RMSE, MSE, MAE, MAPE, and R² values. In addition, in CPI forecasting, it was observed that the GRU deep learning model can be used effectively in the inflation domain. These results provide an effective way to forecast CPI, which is an important component of economic forecasting and inflation management. Moreover, the SHAP (Shapley Additive Explanations) analysis applied for the training and testing phases of the GRU model clarified the contribution of each feature in the GRU model's forecasts and allowed us to understand the effects of variables on the model's forecasting ability. This analysis helped to better understand the success of the GRU model and the economic dynamics underlying the forecasts. This study demonstrates the applicability of the GRU deep learning model in economics and finance and provides a valuable tool for economic and financial decisionmakers. [ABSTRACT FROM AUTHOR]

With escalating environmental concerns worldwide, the shift towards second-hand car markets has emerged as an eco-friendly alternative to reduce the carbon footprint associated with manufacturing new vehicles. However, the lack of accurate and efficient price prediction mechanisms may impede the growth and efficiency of these markets. This study, focusing on the Turkish second-hand car market, contributes towards addressing this gap by introducing a unique, comprehensive dataset gathered from various online markets across Turkey, thereby offering a broad spectrum of data pertaining to different vehicle types, specifications, and resale conditions. The study employs both classical machine learning methods, specifically decision trees, and deep learning models to predict used car prices. This comparative analysis aims to assess the potential of these methods in improving the predictability and transparency of resale price determination. Despite the superior performance of decision tree models, the study found that deep learning techniques achieved comparable results, indicating their potential for further optimization and enhancement. The accurate prediction of resale prices could streamline the operations of second-hand car markets, increasing their appeal to potential buyers and sellers. This could also contribute to environmental sustainability by significantly reducing the demand for new cars. [ABSTRACT FROM AUTHOR]

In the face of the rapidly increasing world population today, researchers have turned to studies aiming to use existing resources more effectively and efficiently, while also exploring new resources to meet the increasing demands, such as raw materials and nutrients. Hydroponic agriculture has been gaining popularity day by day as one of the alternative methods to fulfill crucial human needs. Its characteristics, including resistance to weather conditions, indoor applicability, and vertical orientation, set hydroponic agriculture apart from traditional methods. The absence of soil in this agricultural approach necessitates more observation and supervision. In this study, the use of machine learning was investigated to overcome the observation and surveillance processes that must be done continuously for the healthy growth of plants. Firstly, we developed a hydroponic prototype to assess this goal. With the developed hydroponic prototype, plant water and wastewater data to be used in the evaluation of the growth and development of plants were obtained by sensors. The data obtained through Arduino was stored in the database and used in the training processes of machine learning algorithms. Our experimental study, which utilized five machine learning and deep learning methods, demonstrated a significant increase in hydroponic agricultural efficiency. Notably, deep learning outperformed other methods with a 99.7% success rate. In conclusion, our study shows that machine learning can be used effectively in hydroponic agriculture by providing observation and surveillance of plants. [ABSTRACT FROM AUTHOR]

This study predicts the stock price of Petkim Petrokimya Holding Corp. (PETKM), which is listed in Borsa Istanbul (BIST), using PETKM stock price, US dollar (USD/TRY) price and BIST Chemical, Petroleum Plastic (XKMYA) index price. A time series data set with three inputs and one output is created using these data. Random Forest Regression (RFR), Long-Short Term Memory (LSTM), and Convolutional Neural Network (CNN) algorithms are used in the prediction model. The success of these methods is compared using performance metrics such as MSE, RMSE, MAE, and R2. According to the calculated error metrics, LSTM and RFR algorithms gave better results than CNN with an MSE value less than 0.02. However, the fact that the R2 values of the most successful models created with all three algorithms were greater than 95% revealed that all the algorithms mentioned could be used to estimate this data set.

Yield estimation is an important field of study in agriculture. Forecasting yields provides producers, consumers, traders and policymakers with important preliminary information and time to take necessary action. Corn is an important product in terms of international trade and is widely used in human and animal nutrition throughout the world. Adana produces the highest amount of corn sown both as main and secondary product in Türkiye. Therefore, in this study, corn yield was tried to be estimated by using various meteorological parameters and plant fertilizer usage amounts. For this purpose, statistical (Auto-ARIMA), machine learning (Random Forest) and deep learning (CNN, LSTM) methods were used. The study findings showed that all models used predicted maize yield highly accurately. However, the highest accuracy LSTM model estimated the yield of first corn crop. [ABSTRACT FROM AUTHOR]

The rapid increase in data production, thanks to technological developments and scientific research, leads to the development of Machine Learning (ML) and similar new data analysis tools. It was announced that Amazon Web Services (AWS), a cloud service provider, stored 500EB of data in 2021 [1]. ML is an alternative to traditional engineering methods and does not require field knowledge of the problem to obtain a solution. However, the implementation of ML Algorithms can be complex depending on the content of the data set, and expert knowledge is the most important factor to use these algorithms effectively. Various methods have been developed to find a solution to this problem. There are many different areas and problems that machine learning can be applied to. We have limited our research to problems that can be solved using computer vision and AutoML. We have used AutoML and computer vision-based solutions to solve object classification, detection and segmentation problems. Our goal is to develop a platform that will work without the intervention of any expert. Users can load their datasets, choose the method they want, and train their models according to the problem they choose without any other intervention. After the training process is over, they can use their models in real time by transferring them over the platform in real time with their own hardware. [ABSTRACT FROM AUTHOR]

The restrictions and closures experienced during the COVID-19 pandemic period have affected the global supply chains greatly. The logistics sector is among the most affected sectors from this process. For this reason, accurate and fast estimation of logistics demand is important for effective resource planning. In this study, the aim is to predict the demand accurately in a third-party logistics company during the COVID-19 pandemic period. The shipment data of a logistics company between June 2020 and December 2020 were examined, and the prediction problem was considered as univariate time series. In the scope of the study, a deep learning-based demand forecasting model is proposed. In the proposed prediction model, convolutional neural network (CNN) and long short-term memory (LSTM) network are integrated. CNN provides feature extraction, LSTM captures long-term dependencies, and the proposed model is called hybrid CNN-LSTM. The prediction performance of the hybrid CNN-LSTM was evaluated by comparing it with the classical prediction approaches as well as machine learning and deep learning approaches. The parameter values of all forecasting methods were determined by experimental studies. According to the experimental results, the proposed hybrid CNN-LSTM method showed higher performance than the other methods. The proposed approach generates input to workforce and resource planning activities by providing accurate estimation of logistics demand. [ABSTRACT FROM AUTHOR]

One of the most common problems in engineering is contact problems. In recent years, researchers have turned to alternative methods that can offer effective solutions in a shorter time, instead of solutions containing complex and long mathematical expressions. This study focuses on the estimation of the contact lengths in a homogeneous elastic layer suppressed by two elastic punches with two solution methods. Firstly, a new model was designed for estimation using Deep Learning Neural Network (DNN), one of the deep learning structures. Estimation of contact lengths was provided with the output of the DNN model, which was fed with the homogeneous elastic layer, the ratio of shear modules of the punches and the input parameters of punch radii. The finite element method was used as the second solution method. The problem was modelled in the ANSYS programme, and the solution was made with the same parameters used in DNN modelled. The results obtained from both solutions were compared with the solutions obtained by the theory of elasticity and classical NN in the literature. It had been seen that the results obtained with DNN and ANSYS were compatible with the results obtained with analytical and classical NN and the margin of error was smaller. [ABSTRACT FROM AUTHOR]

Due to their starting and running torque needs as well as their four-quadrant operation, modern industrial drives utilise induction motors (IM). Failures in the rotor bars of the motor can be found using the voltages and currents of each of the three phases as well as the acceleration and velocity signals. For the diagnosis of the quantity of broken rotor bars for a failed IM, conventional signal processing-based feature extraction techniques and machine learning algorithms have been applied in the past. The number of broken rotor bars is determined in this study by looking into a novel technique. For the aforementioned aims, specifically, the deep learning methodologies are studied. In order to do this, convolutional neural network (CNN) transfer learning algorithms are described. Initially, a bandpass filter is used for denoising, and then the signals are transformed using the continuous wavelet transform to create time-frequency pictures (CWT). The collected images are used for deep feature extraction and classification using the support vector machine (SVM) classifier, as well as for fine-tuning the pre-trained ResNet18 model. Metrics for performance evaluation employ categorization accuracy. Additionally, the results demonstrate that the deep features that are recovered from the mechanical vibration signal and current signal yield the greatest accuracy score of 100%. Nonetheless, a performance comparison with the publicly available techniques is also done. The comparisons also demonstrate that the proposed strategy outperforms the compared methods in terms of accuracy scores. [ABSTRACT FROM AUTHOR]

Skin cancer is one of the most common type of cancer in humans. This type of cancer is produced by skin cells called melanocytes and occurs as a result of division and multiplication of the mentioned cells. The most important symptom of skin cancer is the formation of spots on the skin or the observation of changes in the shape, color, or size of the existing spot. It is necessary to consult a specialist to distinguish the difference between a normal spot and skin cancer. Expert physicians examine and follow up the spots on the skin using skin surface microscopy, called dermatoscopy, or take a sample from the suspicious area and request it to be examined in laboratory environment. This situation increases the cost of the procedure for the diagnosis of skin cancer and also causes it to be treated at a later stage. Therefore, there is a need for a method that can detect skin cancer early. Thanks to machine learning, become popular in recent years, many diseases can be diagnosed with software that helps expert physicians. In this study, VGGNet model structures (VGG-11, VGG13, VGG-16, VGG-19) that quickly classify skin cancer and become a traditional convolutional neural network architecture using deep learning method, a subfield of machine learning, were used. It has been observed that the VGG11 architecture, which is one of the VGGNet model structures, detects skin cancer with superior success accuracy (83%) compared to other model structures [ABSTRACT FROM AUTHOR]

Sleep disorders have high prevalence and cause various health problems. For the diagnostics of these disorders and assessment of the sleep quality, many physiological data are collected using polysomnogram (PSG) method. The most important PSG data is the EEG recorded from the brain during sleep. Analysis of hours of sleep EEG data by experts is an onerous task which requires high attention. Recently, many automatic sleep staging classifiers using EEG are developed in order to prevent human error, and to provide a quick objective analysis. They use machine learning techniques and predict the sleep stage of each EEG epoch. Compared to traditional machine learning, deep learning which requires no hand-crafted feature extraction was able to classify sleep stages better. 1D Convolutional Neural Networks (CNN) are the main methods used in automatic sleep staging recently. In this research a simple 2D-CNN based automatic sleep staging feasibility is investigated. It has been found that a 2D CNN can classify the sleep stages by accuracy of 92.55% and with a Cohen's kappa of 0.82. [ABSTRACT FROM AUTHOR]

In parallel with the development of Internet and wireless communication technologies, studies in the field of IoT are also progressing. With the IoT sensors used in the healthcare field, it becomes easier to follow the patients closely. In addition, it is possible to create statistics that will support the treatment process with the data collected from the patients. However, besides the provided facilities, IoT devices that communicate wirelessly and are connected to the internet also have some problems such as security. Serious problems can occur as a result of attacks on different layers of IoT, which is used in healthcare environments. Exposure of sensitive data in the field of Health to any of these attacks can have negative consequences, such as changing the data out of reach of authorized users or capturing it by an attacker. This article attempts to predict duplication, interception, and modification attacks in Message Queuing Telemetry Transport (MQTT) message using artificial intelligence techniques using a complete and labeled IoT dataset containing real world behaviors in IoT networks. On the dataset used, SVM algorithm has Accuracy 85%, f1 98%, Recall 100% values; Naive Bayes (NB) algorithm has Accuracy 89%, f1 86%, Recall 100% values; LSTM has Loss 6.7%, Accuracy 98%, f1 98%, Recall 98%. The LSTM algorithm, which is a deep learning algorithm in detecting abnormal behaviors, has performed better than existing machine learning approaches with low loss and high accuracy data.

Driver drowsiness detection is an important issue to prevent traffic accidents. 40% of severe traffic accidents are due to drowsiness. Various methods are used for driver drowsiness detection. One of the driver drowsiness detection method is driver drowsiness detection based on the analysis of signals such as EEG and ECG. Another driver drowsiness detection method is driver drowsiness detection based on vehicle-driver interaction. The last driver drowsiness detection method used in the study is driver drowsiness detection from images. This method is more advantageous than the other two methods in terms of cost and usability because no driver intervention required. Classical image processing techniques and deep learning algorithms are used for driver drowsiness detection from images. Recent driver drowsiness detection studies are based on deep learning models. In addition, the model to be developed will need to be able to work on mobile devices in order to ensure widespread use. In the study, Convolutional Neural Networks were used for driver drowsiness detection on mobile devices. In order to increase the success rate of the model, the pre-trained model was reused with the transfer learning technique. The model developed for the training consists of 14 layers and 1,236,217 parameters. The dataset consists of two categories, open-eye and closed-eye images. The developed model achieved 95.65% accuracy, 95.86% precision, 94.32% recall and 95.17% f1 score which achieved better results than previous studies. A dataset of 2425 images was used to train the model. [ABSTRACT FROM AUTHOR]
