Abstract

This study addresses the challenges of sentiment classification arising from the vastness of textual data by introducing a three-phase adversarial fine-tuning framework. In this framework, a base model is trained using a transformer encoder, multi-head attention, and a BiLSTM layer on preprocessed data, followed by the creation of a systematic generator that applies fourteen controlled perturbations at varying intensities to the adversarial datasets. In the base article, stage-wise training was conducted sequentially on preprocessed data and on different levels of adversarial datasets, demonstrating significant improvements particularly on a noisy dataset (level 3). Overall, this approach effectively enhances the robustness and reliability of sentiment classifiers in big data contexts with corrupted text. In the proposed method, by incorporating an optimized RCCN network and multi-agent SVM-based clustering, factors were re-clustered, resulting in the proposed algorithm achieving an accuracy rate of 97.86%.
