Methodology Overview
The OEMPTER-ISCSO model employs a multi-stage approach for robust textual emotion recognition. This includes meticulous text pre-processing, FastText-based word embeddings, an ensemble of deep learning classifiers (EDBN, ELNN, ITCN), and an improved Sand Cat Swarm Optimization (ISCO) for hyperparameter tuning. This comprehensive pipeline ensures high accuracy and efficient processing, particularly for real-time applications.
Text Pre-processing & Embedding
Initially, the text undergoes multi-level pre-processing involving cleaning, normalization, and tokenization to remove noise and irrelevant data. This enhances the quality of extracted features. Subsequently, the FastText method is utilized for word embedding, transforming words into numerical vector representations. FastText's ability to capture sub-word data is crucial for handling out-of-vocabulary (OOV) words and morphologically rich languages, improving robustness in noisy or domain-specific datasets.
Ensemble Deep Learning Classifiers
For emotion detection, an ensemble of three powerful classifiers is used: the enhanced Deep Belief Network (EDBN), Elman Neural Network (ELNN), and an improved Temporal Convolutional Network (ITCN). This ensemble approach leverages the unique strengths of each model to capture hierarchical, abstract, spatial, and temporal features effectively, significantly boosting the accuracy and robustness of emotion classification compared to single-model approaches.
Hyperparameter Optimization with ISCO
The Improved Sand Cat Swarm Optimization (ISCO) method is employed to fine-tune the hyperparameters of the ensemble architecture. ISCO is chosen for its superior exploration-exploitation balance and fast convergence rate, dynamically altering search directions using adaptive coefficients inspired by sand cat hunting behavior. This optimization process prevents local optima, ensures faster convergence, and minimizes computational cost, leading to enhanced model accuracy and mitigated overfitting.

Application for Disabled Communication
The OEMPTER-ISCSO model significantly enhances real-time communication for individuals with disabilities by accurately interpreting their emotional states from text. For example, in an assistive communication device, a user expressing frustration (e.g., 'This is so slow and difficult') can have their emotion recognized and the device can suggest more efficient input methods or offer calming responses. This rapid and precise emotional understanding allows for more empathetic and effective human-computer interaction, creating sustainable and supportive environments. The system's robustness to diverse language patterns ensures reliable performance across different users and contexts, making assistive technologies truly intelligent and responsive.
- Real-time emotional interpretation for assistive devices.
- Improved empathetic responses in communication.
- Robustness to diverse textual expressions.
