Advanced functional connectivity analysis with integrated EEG signal enhancement and GTW-EEG-GAN for emotion detection

Emotion recognition is crucial in human-computer interaction and psychological research, utilizing modalities such as facial expressions, voice intonations, and EEG signals. This research investigates AI-driven techniques by employing Graph Neural Networks (GNNs) on functional connectivity matrices derived from EEG data to advance emotion recognition. Our approach integrates sophisticated preprocessing methods, including Integrated EEG Signal Enhancement (IESE) and novel augmentation techniques such as Gaussian Time Warping Generative Adversarial Network (GTW-EEG-GAN). This integration aims at enhancing data quality and diversity. Signal decomposition using EMD-Wavelet Hybrid Decomposition further refines feature extraction, enabling robust analysis of EEG signals. Functional connectivity metrics capture critical neural interactions intended for precise emotion characterization. The GNN architecture effectively processes these features, achieving significant accuracy improvements. Evaluations on the DEAP dataset demonstrate promising results, attaining 94.5% accuracy before hyperparameter tuning and further improving to 98.6% after tuning, highlighting the system's efficacy. The methodology showcases the integration of advanced signal processing techniques with AI, offering a comprehensive framework for future studies. The findings advocate potential applications in areas such as personalized mental health monitoring, adaptive learning environments, and responsive gaming experiences, demonstrating the broad impact and versatility of AI-driven EEG-based emotion recognition.

Beyond words: analyzing non-verbal communication techniques in a medical communication skills course via synchronous online platform.

Effective doctor-patient relationships hinge on robust communication skills, with non-verbal communication techniques (NVC) often overlooked, particularly in online synchronous interactions. This study delves into the exploration of NVC types during online feedback sessions for communication skill activities in a medical education module. A cohort of 100 first-year medical students and 10 lecturers at the Faculty of Medicine, Universiti Kebangsaan Malaysia (UKM), engaged in communication skills activities via Microsoft Teams. Sessions were recorded, and lecturer NVC, encompassing body position, facial expressions, voice intonation, body movements, eye contact, and paralinguistics, were meticulously observed. Following these sessions, students provided reflective writings highlighting their perceptions of the feedback, specifically focusing on observed NVC. The study identified consistent non-verbal communication patterns during feedback sessions. Lecturers predominantly leaned forward and toward the camera, maintained direct eye contact, and exhibited dynamic voice intonation. They frequently engaged in tactile gestures and paused to formulate thoughts, often accompanied by filler sounds like "um" and "okay." This consistency suggests proficient use of NVC in providing synchronous online feedback. Less observed NVC included body touching and certain paralinguistic cues like long sighs. Initial student apprehension, rooted in feelings of poor performance during activities, transformed positively upon observing the lecturer's facial expressions and cheerful intonation. This transformation fostered an open reception of feedback, motivating students to address communication skill deficiencies. Additionally, students expressed a preference for comfortable learning environments to alleviate uncertainties during feedback reception. Potential contrivances in non-verbal communication (NVC) due to lecturer awareness of being recorded, a small sample size of 10 lecturers limiting generalizability, a focus solely on preclinical lecturers, and the need for future research to address these constraints and explore diverse educational contexts. Medical schools globally should prioritize integrating NVC training into their curricula to equip students with essential communication skills for diverse healthcare settings. The study's findings serve as a valuable reference for lecturers, emphasizing the importance of employing effective NVC during online feedback sessions. This is crucial as NVC, though occurring online synchronously, remains pivotal in conveying nuanced information. Additionally, educators require ongoing professional development to enhance proficiency in utilizing NVC techniques in virtual learning environments. Potential research directions stemming from the study's findings include longitudinal investigations into the evolution of NVC patterns, comparative analyses across disciplines, cross-cultural examinations, interventions to improve NVC skills, exploration of technology's role in NVC enhancement, qualitative studies on student perceptions, and interdisciplinary collaborations to deepen understanding of NVC in virtual learning environments.

Spanish MEACorpus 2023: A multimodal speech–text corpus for emotion analysis in Spanish from natural environments

In human–computer interaction, emotion recognition provides a deeper understanding of the user’s emotions, enabling empathetic and effective responses based on the user’s emotional state. While deep learning models have improved emotion recognition solutions, it is still an active area of research. One important limitation is that most emotion recognition systems use only text as input, ignoring features such as voice intonation. Another limitation is the limited number of datasets available for multimodal emotion recognition. In addition, most published datasets contain emotions that are simulated by professionals and produce limited results in real-world scenarios. In other languages, such as Spanish, hardly any datasets are available. Therefore, our contributions to emotion recognition are as follows. First, we compile and annotate a new corpus for multimodal emotion recognition in Spanish (Spanish MEACorpus 2023), which contains 13.16 h of speech divided into 5129 segments labeled by considering Ekman’s six basic emotions. The dataset is extracted from YouTube videos in natural environments. Second, we explore several deep learning models for emotion recognition using text- and audio-based features. Third, we evaluate different multimodal techniques to build a multimodal recognition system that improves the results of unimodal models, achieving a Macro F1-score of 87.745%, using late fusion with concatenation strategy approach.

And currently social media is the most effective medium for promotion and information fields that can be used to see the extent to which people care and care about other people's work. One of the information and promotion platforms is YouTube as an audio visual that is easy to see and hear. by society. A person who has a YouTube account is called a YouTuber. The term YouTuber has become popular in recent years, and YouTubers have emerged with daily vlog content. A YouTuber who has many subscribers with positive content is Jang Hansol with the name YouTube Korea Reomit. This YouTuber from South Korea started his career on August 26 2016. Netizens have become well-known to his name because of his ability to speak Javanese, complete with his trademark medhok accent, because he has lived in Indonesia, especially the city of Malang, for dozens of years. This research uses qualitative methods to obtain overall results and conclusions. This research examines social reality using a tectonic model. The constructivist model is almost the antithesis of the understanding that places observation and objectivity in the search for facts or science. This model views social science as a systematic analysis of socially meaningful action through direct and detailed observation of social actors involved in creating and maintaining/administering managing their social world. The results of this research from the sensation stage show that audience vision allows a person to observe facial expressions, body gestures and visual appearances which are part of a person's personal branding. Information processed through the sense of sight helps the audience form an initial impression of the person, such as whether they exhibit confidence, expertise, or a certain personality. Audiences use the sense of sight to form an initial impression of someone's personal branding through observing facial expressions, body gestures and visual appearance. Audiences use their sense of hearing to form an initial impression of other people's personal branding by capturing voice intonation, speaking style and verbal messages, as well as providing information based on what they hear. The conclusion of this research is that Jang Hansol's personal branding through online platforms is the key to building her unique identity and achieving professional goals. Audiences experience stages of sensation, attention, and interpretation when watching Jang Hansol's actions. The opinions formed from his personal branding reflect the diversity of perspectives and audiences' understanding of the character and values he displays. Jang Hansol's personal branding also influences the formation of audience trust, with consistency, authenticity and integrity being key elements in this process.The trust that is built influences how the audience interacts with Jang Hansol in the future. Apart from that, Jang Hansol's personal branding also influences audience decisions.

Multimodal Emotion Recognition System Using Machine Learning Classifier

Multi-modal emotion recognition refers to the process of identifying human emotions using information from multiple sources, such as facial expressions, voice intonation, EEG signals etc. Ultimately, emotion recognition is poised to play a pivotal role in healthcare, education, customer service etc. As we progress, it is imperative to address privacy concerns associated with this technology in a responsible manner. Challenges in multi-modal emotion recognition include aligning data from different modalities in time, dealing with noisy or incomplete information. In this paper, we aim to address this issue by employing the SVM as our machine learning classifier. Here we use IEMOCAP for speech and video and DEAP dataset for EEG signals. After applying SVM we got 76.22 % accuracy for IEMOCAP and 68.89 % accuracy for DEAP dataset.

Atypical mismatch negativity during sleep in young children with autism spectrum disorder

Objectives: Autism spectrum disorders (ASD) are pervasive developmental disorders.The prevalence of ASD has risen sharply in the last few years, reaching 1 in 68. Previous studies have found that abnormal auditory processing is the most common and one of the early sensory abnormalities in ASD children, which may relate to clinical manifestations such as poor language ability, pitch and voice intonation, and insensitivity or hypersensitivity to sound. Mismatch negativity (MMN) is considered as an optimal electrophysiological indicator in the pre-attentive central processing of acoustic change detection. Previous MMN studies on ASD were limited to children and adults older than five. This may be related to the difficulty for young children to cooperate with MMN recording in the awake state. Meta-analysis study indicated mixed findings on MMN latencies and amplitudes in ASD, possibly due to the different stimulation types and age ranges. This is the first study to record cotical auditory evoked potentials(CAEPs) and MMNs induced by frequency change in ASD children constrained from 2 to 5 years old. Method: MMNs were recorded from eighteen ASD children and typical controls during sleeping. The oddball paradigm for approximately 15-min lengths was given with standard (80%, 1000 Hz, 40-millisecond duration) and frequency deviant (20%, 2000 Hz, 40-millisecond duration). The presentation rate was 1.1 per second. A total of 750 stimuli were presented to each subject to obtain at least 150 deviant stimuli.The CAEP latencies and amplitudes were labeled.MMN areas were calculated based on the marked latencies and amplitudes. The latencies and amplitude of CAEPs and the latency, amplitude, and area of MMNs were recorded. Results: Our data showed that the latencies of MMN were significantly longer, and the amplitudes were significantly smaller in ASD children than those in typical controls. Due to the MMN representing the integrity of the primary auditory cortex and its auditory pathway projecting to the hippocampus, prolonged MMN response in ASD children may be related to the lack of mature axons in the deeper cortex and prolonged myelination. Conclusions: This is the first study that reported MMN response characteristics evoked by acoustic stimulation with a 100% frequency rise at 1kHz in young ASDs during sleepness. Findings from the current research indicate that MMN recording could be reliably recorded in young children with ASD at an early age to assess auditory discrimination function. There is much work to be done to further the scientific underpinning of this measurement. Studying young ASD children is essential to understand the impact of the sound encoding process on language development. Future directions should focus on understanding the association between auditory processing characteristics and ASD core symptomatology (namely, social communication and restricted/repetitive behaviors), independent of language development levels.

Implementation of Mel-Frequency Cepstral Coefficient as Feature Extraction using K-Nearest Neighbor for Emotion Detection Based on Voice Intonation

Purpose: To determine emotions based on voice intonation by implementing MFCC as a feature extraction method and KNN as an emotion detection method.Design/methodology/approach: In this study, the data used was downloaded from several video podcasts on YouTube. Some of the methods used in this study are pitch shifting for data augmentation, MFCC for feature extraction on audio data, basic statistics for taking the mean, median, min, max, standard deviation for each coefficient, Min max scaler for the normalization process and KNN for the method classification.Findings/result: Because testing is carried out separately for each gender, there are two classification models. In the male model, the highest accuracy was obtained at 88.8% and is included in the good fit model. In the female model, the highest accuracy was obtained at 92.5%, but the model was unable to correctly classify emotions in the new data. This condition is called overfitting. After testing, the cause of this condition was because the pitch shifting augmentation process of one tone in women was unable to solve the problem of the training data size being too small and not containing enough data samples to accurately represent all possible input data values.Originality/value/state of the art: The research data used in this study has never been used in previous studies because the research data is obtained by downloading from Youtube and then processed until the data is ready to be used for research.
