Data science is increasingly leaning towards real-time solutions and data streaming plays a pivotal role in this shift. One of its applications is predictive modeling.

If we take the example of identifying phishing websites, the necessary features like the URL’s length or the domain’s age are extracted from the dataset.

The process involves deploying the model into the streaming pipeline and performing model scoring on every single data point as they stream in. This is a significant step forward from the traditional offline or batch prediction model, offering immediate insights as data comes in.

Online Learning With Data Streaming

One of the key areas where data streaming has made a marked difference in data science is model updating. In traditional approaches, organizations would update models offline by collecting all new observations and periodically retraining the model, typically overnight or weekly. But with data streaming, online learning is possible.

In online learning, the model gets updated for every new observation that comes in, helping the model adapt to new trends much more quickly. Also, when datasets are too large to train on in their entirety, online learning proves beneficial in training the model incrementally. This constant learning and adjusting give the model an added edge, as it continually evolves with the incoming data.
