With the development of information and technology, especially with the boom in big data, healthcare support systems are becoming much better. Patient data can be collected, retrieved, and stored in real time. These data are valuable and meaningful for monitoring, diagnosing, and further applications in data analysis and decision-making. Essentially, the data can be divided into three types, namely, statistical, image-based, and sequential data. Each type has a different method of retrieval, processing, and deployment. Additionally, the application of machine learning (ML) and deep learning (DL) in healthcare support systems is growing more rapidly than ever. Numerous high-performance architectures are proposed to optimize decision-making. As reliability and stability are the most important factors in the healthcare support system, enhancing the predicted performance and maintaining the stability of the model are always the top priority. The main idea of our study comes from ensemble techniques. Numerous studies and data science competitions show that by combining several weak models into one, ensemble models can attain outstanding performance and reliability. We propose three deep ensemble learning (DEL) approaches, each with stable and reliable performance, that are workable on the above-mentioned data types. These are deep-stacked generalization ensemble learning, gradient deep learning boosting, and deep aggregation learning. The experiment results show that our proposed approaches achieve more vigorous and reliable performance than traditional ML and DL techniques on statistical, image-based, and sequential benchmark datasets. In particular, on the Heart Disease UCI dataset, representing the statistical type, the gradient deep learning boosting approach dominates the others with accuracy, recall, F1-score, Matthews correlation coefficient, and area under the curve values of 0.87, 0.81, 0.83, 0.73, and 0.91, respectively. On the X-ray dataset, representing the image-based type, the deep aggregation learning approach shows the highest performance with values of 0.91, 0.97, 0.93, 0.80, and 0.94, respectively. On the Depresjon dataset, representing the sequence type, the deep-stacked generalization ensemble learning approach outperforms the others with values of 0.91, 0.84, 0.86, 0.8, and 0.94, respectively. Overall, we conclude that applying DL models using our proposed approaches is a promising method for the healthcare support system to enhance prediction and diagnosis performance. Furthermore, our study reveals that these approaches are flexible and easy to apply to achieve optimal performance.

<title>Abstract</title> Bone cancer diagnosis is imperative for diagnosing and treating many forms of primary and metastatic bone cancers early. Traditional imaging techniques, such as CT, MRI, and X-ray scans, are effective but typically involve manual interpretation, which is laborious and prone to human mistake. With increased accuracy, dependability, and efficiency over conventional techniques, automated bone cancer diagnosis systems have been made possible by recent developments in machine learning (ML) and deep learning (DL). Even though a large portion of the recent literature has made significant strides in the diagnosis of bone cancer using deep learning techniques, many of these methods have numerous drawbacks, including computational complexity, overfitting in certain situations, and a lack of reliable databases. The objective of this research is to develop a method that can diagnose bone cancer as quickly, efficiently, and affordably as feasible. This method's main contribution is the combination of EfficientNetB4 and SVM algorithms, which improves accuracy, speed, and accessibility while making use of large datasets and reliable assessment measures. Combining EfficientNetB4 and SVM is crucial for diagnosing bone cancer because it harnesses the EfficientNetB4 technique's amazing capacity to extract useful features both quantitatively and qualitatively, as well as the SVM's significant advantage when it comes to binary separation. After a thorough analysis of numerous research, it was determined to combine these methods as they are distinguished by their great efficiency and simplicity in job implementation, especially in medical environments where accuracy and interpretability are of utmost importance The success of the suggested methods was shown by experiments on a large dataset (which contains 35244 X-ray images), which produced 98% precision, 97.47% recall, 98% accuracy, and 98% F1-score. The suggested method's better performance and computational economy are highlighted by comparison with machine learning, deep learning, and transfer learning techniques. Furthermore, the suggested system encounters a quick inference time of 41 ms, which qualifies it for clinical real-time applications. This study offers a viable strategy for early detection and better treatment outcomes by demonstrating the potential of integrating deep learning and traditional machine learning approaches for better bone cancer diagnosis.
