This final section introduces the key elements of the training and classification workflow. A test case using a simple logistic regression is used to illustrate each step of the computational workflow.
An overview of computational workflows
In its simplest form, a computational workflow to perform runtime processing of a dataset is composed of the following stages:
- Loading the dataset from files, databases, or any streaming devices.
- Splitting the dataset for parallel data processing.
- Preprocessing data using filtering techniques, analysis of variance, and applying penalty and normalization functions whenever necessary.
- Applying the model—either a set of clusters or classes—to classify new data.
- Assessing the quality of the model. ...
