Creating best fit predictions

Best fit predictions offer the capability to determine the most suitable item or value of an item attribute for each customer. By configuring the prediction, you can specify the attribute value you are interested in, such as brand, ID, color, or any other item attribute available in your item feed. The prediction result will then provide you with the attribute value that is most likely to be relevant to the customer.

You can create a best fit prediction from scratch or by using one of the predefined scenarios:

• Find best fit from brand, category or other attribute for a given customer
• Find the overall best item for a given customer

Predefined scenarios are configured using a user-friendly wizard that allows you to adjust scenario settings according to your preferences. This is done through a step-by-step configuration form, which provides hints on the interface to guide you. You will be able to select the predefined scenario at the beginning of creating the prediction (Select the model type).

Prerequisites

• Configure AI Engine for Propensity and Best Fit. It usually takes several hours to initialize the model and perform necessary calculations.
• The attributes that you want to use for best fit predictions must be added to filterable attributes.

Configure a prediction

Select the model type

1. Go to > New prediction.
2. On the pop-up, select one of the following options:
   • Use predefined prediction - This option allows you to use the ready-made prediction scenarios and adjust their settings to your preferences in a user-friendly, step-by-step configuration form by following hints shown on the interface. If you select this option, you can skip reading the rest of the article.
   • Create from scratch - This option allows you to create your own configuration of a propensity prediction to achieve your custom business objective. If you use this option, select Best Fit.
