It is only once models are deployed to production that they start adding value, making deployment a crucial step. Run the pipeline by clicking on the "Create pipeline". For example, in text classification it’s common to add new labeled data and update the label space. The pipeline takes labeled data, preprocess it, autotunes a fastText model and outputs metrics and predictions to iterate on. That observation may lead to iterating on the problem to become multilabel and assign all labels above a probability threshold. Separation of concerns is just as for any IT architecture a good practice. The company may want to employ different custom models for recommending different categories of products—such as movies, books, music, and articles. For the purposes of this post, we are focusing on risks requiring realtime or near-realtime action. The final score is logged in JSON and stored by Valohai as an execution metric.
