Machine Learning-based sEMG Signal Classification for Hand Gesture Recognition
Aarotale, Parshuram N., Rattani, Ajita
EMG-based hand gesture recognition uses electromyographic~(EMG) signals to interpret and classify hand movements by analyzing electrical activity generated by muscle contractions. It has wide applications in prosthesis control, rehabilitation training, and human-computer interaction. Using electrodes placed on the skin, the EMG sensor captures muscle signals, which are processed and filtered to reduce noise. Numerous feature extraction and machine learning algorithms have been proposed to extract and classify muscle signals to distinguish between various hand gestures. This paper aims to benchmark the performance of EMG-based hand gesture recognition using novel feature extraction methods, namely, fused time-domain descriptors, temporal-spatial descriptors, and wavelet transform-based features, combined with the state-of-the-art machine and deep learning models. Experimental investigations on the Grabmyo dataset demonstrate that the 1D Dilated CNN performed the best with an accuracy of $97\%$ using fused time-domain descriptors such as power spectral moments, sparsity, irregularity factor and waveform length ratio. Similarly, on the FORS-EMG dataset, random forest performed the best with an accuracy of $94.95\%$ using temporal-spatial descriptors (which include time domain features along with additional features such as coefficient of variation (COV), and Teager-Kaiser energy operator (TKEO)).
Comparison of gait phase detection using traditional machine learning and deep learning techniques
Nazari, Farhad, Mohajer, Navid, Nahavandi, Darius, Khosravi, Abbas
Human walking is a complex activity with a high level of cooperation and interaction between different systems in the body. Accurate detection of the phases of the gait in real-time is crucial to control lower-limb assistive devices like exoskeletons and prostheses. There are several ways to detect the walking gait phase, ranging from cameras and depth sensors to the sensors attached to the device itself or the human body. Electromyography (EMG) is one of the input methods that has captured lots of attention due to its precision and time delay between neuromuscular activity and muscle movement. This study proposes a few Machine Learning (ML) based models on lower-limb EMG data for human walking. The proposed models are based on Gaussian Naive Bayes (NB), Decision Tree (DT), Random Forest (RF), Linear Discriminant Analysis (LDA) and Deep Convolutional Neural Networks (DCNN). The traditional ML models are trained on hand-crafted features or their reduced components using Principal Component Analysis (PCA). On the contrary, the DCNN model utilises convolutional layers to extract features from raw data. The results show up to 75% average accuracy for traditional ML models and 79% for Deep Learning (DL) model. The highest achieved accuracy in 50 trials of the training DL model is 89.5%.
2023 Trends in Artificial Intelligence and Machine Learning: Generative AI Unfolds - insideBIGDATA
At present, the potential for generative Artificial Intelligence--the variety of predominantly advanced machine learning that analyzes content to produce strikingly similar new content--is boundless. These technologies have transcended Natural Language Generation, in which they achieved much of their early renown via paradigms such as Bidirectional Encoder Representations from Transformers (BERT), Generative Pre-trained Transformer 3 (GPT3), and deep neural networks. Although it's still utilized to create verbal summaries of documents and analytics results, generative AI is now widely employed to compose poetry, music, visual arts, and many other things once thought relegated to the realm of human ingenuity. Still, generative AI's benefits of automation, time-to-action, and scalability are the very reasons organizations rely on AI in the first place. Prudent companies will adopt these advantages within broader frameworks for mitigating the shortfalls of advanced machine learning to provide tangible business value for decision support, customer satisfaction, workload optimization, and cost reductions.
Why DeepLearning?
In the Recent Trends in the Field of Artificial Intelligence, DeepLearning has gained more popularity in Reasearch over the years compared to Traditional Machine Learning. Firstly, Deep learning is a subset of machine learning which provides the ability to machine to perform human-like tasks without human involvement. It provides the ability to an AI agent to mimic the human brain. Deep learning can use both supervised and unsupervised learning to train an AI agent. Deep learning is implemented through neural networks architecture hence also called a deep neural network.

Council Post: Deep Learning: AI Without Expert Input
We are used to 20th-century machines that work well for us under normal conditions. We turn on the autopilot once the plane is airborne, but when we suspect an engine problem, we scramble to take manual control. More generally speaking, we are used to machines performing well autonomously, but when a malfunction arises, we rely on human intervention to fix things. The greatest paradigm shift for 21st-century machines may be relying on machines to successfully handle such challenging situations even better than humans. In this series of articles on AI for additive manufacturing, I am covering various aspects of real-world applications of AI.
A Machine Learning Tutorial for Operational Meteorology, Part I: Traditional Machine Learning
Chase, Randy J., Harrison, David R., Burke, Amanda, Lackmann, Gary M., McGovern, Amy
Recently, the use of machine learning in meteorology has increased greatly. While many machine learning methods are not new, university classes on machine learning are largely unavailable to meteorology students and are not required to become a meteorologist. The lack of formal instruction has contributed to perception that machine learning methods are 'black boxes' and thus end-users are hesitant to apply the machine learning methods in their every day workflow. To reduce the opaqueness of machine learning methods and lower hesitancy towards machine learning in meteorology, this paper provides a survey of some of the most common machine learning methods. A familiar meteorological example is used to contextualize the machine learning methods while also discussing machine learning topics using plain language. The following machine learning methods are demonstrated: linear regression; logistic regression; decision trees; random forest; gradient boosted decision trees; naive Bayes; and support vector machines. Beyond discussing the different methods, the paper also contains discussions on the general machine learning process as well as best practices to enable readers to apply machine learning to their own datasets. Furthermore, all code (in the form of Jupyter notebooks and Google Colaboratory notebooks) used to make the examples in the paper is provided in an effort to catalyse the use of machine learning in meteorology.

Evolved AI is better than traditional machine learning.
There are times we need something more powerful than conventional AI, which is described mainly by the data we feed it. We need to add other things we already know and only ask machine learning to learn what we don't know. This idea of blending multiple AI components into a hybrid is what we call Evolved AI at Lone Star. But what does that mean? Intelligence algorithms can be classified by how they predict outcomes and prescribe actions.
How Traditional Machine Learning Is Holding Cybersecurity Back
While global cybersecurity spending now surpasses $100 billion annually, 64 percent of enterprises were compromised in 2018, according to a study by the Ponemon Institute. The standard answer is that wily cyber-criminals are employing ever-evolving, increasingly sophisticated attack methods, part of a never-ending game of cat-and-mouse in which they all too often outsmart the good guys. This is undoubtedly true – but the root of the problem is that traditional machine learning-based cybersecurity solutions fail to keep up with the growing sophistication of today's cyber threats, both those that are created by hackers and AI alike. Why does machine learning so often come up short – and how should cybersecurity evolve to meet the scale and complexity of the challenge? There's no question that machine learning has driven significant improvements in cybersecurity.
