offline learning
What It Means
Offline learning means training an AI model using a complete, fixed dataset all at once, rather than continuously updating the model with new data as it arrives. The model learns from historical data during a dedicated training phase, then gets deployed to make predictions without further learning from live data.
Why Chief AI Officers Care
This approach offers predictable training costs and easier compliance since you know exactly what data was used to train the model. However, models can become outdated quickly in fast-changing business environments since they don't adapt to new patterns or trends automatically, requiring periodic retraining to maintain accuracy.
Real-World Example
A retail company trains a demand forecasting model using two years of historical sales data to predict inventory needs for the next quarter. The model is trained once using all the past data, then deployed to generate forecasts, but won't learn from new sales patterns until the next scheduled retraining cycle.
Common Confusion
People often confuse offline learning with 'offline deployment' - offline learning refers to the training method using static datasets, while a model can still make predictions online even if it was trained offline.
