Real-time machine learning (ML) is becoming increasingly popular as it enables instantaneous data processing and low latency predictions, distinguishing it from traditional ML models that rely on batch processing. This approach is critical in applications such as fraud detection, chat systems, virtual health assistants, and e-commerce recommendation systems, where timely and adaptive responses are essential. The process involves data collection, processing, feature and model selection, training, and deployment, with real-time ML models updating themselves as new data flows in. A tutorial demonstrates implementing a real-time fraud detection system using TensorFlow, BigQuery, and Redpanda, showcasing the integration of these tools for seamless data streaming and analysis. TensorFlow serves as the ML framework for building and training the model, BigQuery offers a scalable data warehouse for storage and querying, and Redpanda facilitates real-time data streaming into BigQuery, culminating in a robust system capable of processing and analyzing real-time data to detect fraudulent activities effectively.
