Special Issue Information

Dear Colleagues,

Deep learning has brought about a transformative change in many industries by giving machines the ability to identify and analyze intricate patterns in large datasets. This advancement is particularly evident in fields like computer vision and robotics, where deep learning-based pose estimation has become an essential tool. Pose estimation refers to the process of determining the position and orientation of objects or people within a given space. Traditional approaches to pose estimation often struggled with significant challenges such as dealing with occlusions—where parts of an object are hidden from view—and adapting to varying environmental conditions, such as changes in lighting or background. However, deep learning has revolutionized this area by offering a more robust and precise method for pose estimation. With the ability to learn from vast amounts of data, deep learning models can generalize well across different scenarios, overcoming the limitations of traditional methods. For instance, in human–computer interaction, accurate pose estimation enables more natural and intuitive interfaces, while in sports analytics, it allows for detailed analysis of athletes' movements, leading to improved performance and injury prevention strategies. In robotics, deep learning-based pose estimation is essential for tasks that require machines to interact with the physical world, such as navigating environments, manipulating objects, or collaborating with humans. The significance of this technology extends to healthcare as well, particularly in the development of intelligent prosthetics and exoskeletons. These devices require precise control over movement to be effective, and deep learning's ability to accurately estimate poses plays a vital role in achieving this. By integrating deep learning with pose estimation, we not only improve existing technologies but also pave the way for new, AI-driven innovations that have the potential to impact a wide range of fields.

This Special Issue aims to explore the breakthrough of deep learning in industries where the identification and analysis of complex patterns in large datasets are critical. Specifically, it will focus on the role of deep learning in advancing pose estimation technologies across various domains such as computer vision, robotics, healthcare, and human-computer interaction. The issue invites contributions that highlight cutting-edge research and applications where deep learning's ability to handle challenges like occlusions and varying conditions has led to significant improvements in accuracy and robustness.

This Special Issue delves into the intersection of deep learning, big data, and cognitive computing—the core focus areas of the journal. The integration of deep learning with pose estimation represents a quintessential application of cognitive computing, where machines mimic human-like understanding and decision-making processes. Moreover, the reliance on large datasets for training deep learning models aligns perfectly with the journal's emphasis on big data. This Special Issue will thus contribute valuable insights to the journal's readership, enhancing their understanding of how deep learning is shaping the future of big data analytics and cognitive computing.

Here are some potential themes for the Special Issue:

  • Achieving accurate pose estimation using big data and intelligent techniques.
  • Enhancing user experience in human–computer interaction with advanced pose estimation techniques.

Walking is a fundamental human activity, and analyzing its complexities is essential for understanding gait abnormalities and musculoskeletal disorders. This article delves into the classification of gait phases using advanced machine learning techniques, specifically focusing on dividing these phases into five distinct subphases. The study utilizes data from 100 individuals obtained from an open-access platform and employs two distinct training methodologies. The first approach adopts stratified random sampling, where 80% of the data from each subphase are allocated for training and 20% for testing. The second approach involves participant-based splitting, training on data from 80% of the individuals and testing on the remaining 20%. Preprocessing methods such as Min–Max Scaling (MMS), Standard Scaling (SS), and Principal Component Analysis (PCA) were applied to the dataset to ensure optimal performance of the machine learning models. Several algorithms were implemented, including k-Nearest Neighbors (k-NNs), Logistic Regression (LR), Decision Tree (DT), Random Forest (RF), Support Vector Machine (SVM), Naive Bayes (Gaussian, Bernoulli, and Multinomial) (NB), Linear Discriminant Analysis (LDA), and Quadratic Discriminant Analysis (QDA). The models were rigorously evaluated using performance metrics like cross-validation score, Mean Squared Error (MSE), Root Mean Squared Error (RMSE), accuracy, and R2 score, offering a comprehensive assessment of their effectiveness in classifying gait phases. In the five subphases analysis, RF again performed strongly with a 94.95% accuracy, an RMSE of 0.4461, and an R2 score of 90.09%, demonstrating robust performance across all scaling methods.
