Machine learning workflow

As explained in Graph Algorithms for Data Science

A machine learning workflow is a sequence of processing and modeling steps for training or applying machine learning models.

A machine learning workflow sequences data transformation, feature construction, and model training or application to solve a specified task. Feature engineering and data wrangling often represent most of the analytical workload. section 2.0

Graph-based workflows follow the same broad pattern as traditional machine learning, but differ in how model features are extracted. Graph data may need reshaping before algorithms can process it. section 2.0

A practical workflow includes:

  • Transform a graph with multiple node or relationship types into the structure expected by an algorithm. section 2.0
  • Construct features from the transformed graph before executing an algorithm or training a model. section 2.0
  • Use graph machine learning for prediction or classification, rather than descriptive analysis such as community detection or centrality. section 2.0

How Graph Algorithms for Data Science covers it

How deep it goes
Explains preprocessing rationale and feature construction at a high level, deferring detailed graph transformations to later techniques.
Examples
Uses multi-type graph reshaping, missing-value prediction, future-behavior classification, community detection, and centrality as examples.
What it assumes
Assumes familiarity with machine learning or data science workflows while clarifying why graph inputs require additional transformation.
What you can do after
Apply it via a graph database query language to prepare algorithm inputs and construct features for machine learning.
How it connects
Connects feature engineering, data wrangling, graph databases, graph algorithms, and graph machine learning.
