Each model is selected based on its suitability for a specific task, and rigorous testing is performed before deployment to ensure that it meets our performance and accuracy standards. The models are regularly retrained using updated Training Datasets to maintain their effectiveness and adapt to evolving data patterns. The selection process also considers factors like Licensing Requirements and vendor support.
Model 1: BERT for Natural Language Processing
BERT (Bidirectional Encoder Representations from Transformers) is a transformer-based machine learning technique for natural language processing (NLP) pre-training. We utilize a fine-tuned version of BERT for tasks such as sentiment analysis, text summarization, and question answering. It is particularly effective in understanding the context of words within a sentence, leading to more accurate results compared to traditional NLP methods. The model is deployed using a dedicated cluster of servers with substantial GPU Resources to handle the computational demands. This model is critical for our Content Moderation System.
