How to log your model schema for regression models

Regression Model Overview

Regression models have a continuous, numeric output. (Examples: click-through rates, sales forecasting, customer lifetime value, ETA models, etc.)

Performance Metrics

# Declare the schema of the dataframe you're sending (feature columns, predictions, timestamp, actuals)

actual_score_column_name="actual_score",

tag_column_names=["zip_code", "age"]
)
# Log the dataframe with the schema mapping
response = client.log(

features = {
'score': '88.5',
'pos_approved': False,

tags = {
'zip_code': '12345'
'age': '25'
}

Quick Definitions

Prediction Label: The numeric value of the prediction (float | int)
Actual Label: The numeric value of the actual (float | int)
