Introduction

Brain-Computer Interfaces (BCIs) have witnessed remarkable progress in recent years, driven by advancements in Artificial Intelligence (AI) and Machine Learning (ML) techniques. This mini review explores the intersection of AI and ML with BCIs, providing insights into both invasive and non-invasive types of BCIs. Additionally, we summarize the role of AI and ML in processing and analyzing brain signals, compare various algorithms, highlight key findings, and propose future research directions to advance BCI systems [1].

Literature Review

AI and ML play pivotal roles in enhancing the performance and usability of BCIs. These techniques enable the development of adaptive and intelligent systems capable of decoding complex brain signals with high accuracy and efficiency. AI algorithms, such as deep learning models, reinforcement learning, and pattern recognition techniques, offer novel approaches for extracting meaningful information from brain signals and translating them into actionable commands or feedback [2]. BCIs can be categorized into invasive and non-invasive types based on the method of accessing brain signals. Invasive BCIs involve implanting electrodes directly into the brain tissue, providing high spatial resolution but requiring surgical procedures. Non-invasive BCIs, on the other hand, utilize external sensors placed on the scalp or other parts of the body to detect brain activity, offering greater accessibility and user comfort [3].

Discussion

AI and ML techniques revolutionize signal processing and analysis in BCIs by automatically extracting features, reducing noise, and classifying brain signals into meaningful categories. These solutions enable real-time decoding of user intentions, facilitating seamless interaction with external devices or virtual environments. Moreover, AI-driven approaches adaptively adjust BCI parameters based on user feedback and physiological changes, enhancing system performance and user experience [4]. A comparison of AI and ML algorithms reveals varying performance metrics, computational complexity, and suitability for different BCI applications. Key findings suggest that deep learning models, such as convolutional neural networks (CNNs) and Recurrent Neural Networks (RNNs), demonstrate promising results in decoding complex brain signals and improving BCI accuracy. However, challenges remain in addressing issues such as signal variability, robustness, and individual variability. Future research directions include exploring hybrid AI-ML approaches, integrating multimodal data sources, and enhancing BCI adaptability and reliability [5,6].

Conclusion

In conclusion, AI and ML-based methods have revolutionized the field of BCIs, offering innovative solutions for signal processing, analysis, and user interaction. Both invasive and non-invasive BCIs benefit from AI-driven approaches, paving the way for more accessible and efficient brain-computer interaction systems. Continued research and collaboration are essential to address remaining challenges and unlock the full potential of AI and ML in advancing BCIs for medical, assistive, and neuroscientific applications.
