Datos Tabulares
Entrena modelos en datos estructurados como CSVs y bases de datos.
Inicio Rápido
aitraining tabular --train \
--model xgboost \
--data-path ./data.csv \
--target-columns target \
--valid-split validation \
--project-name tabular-model
El entrenamiento tabular requiere --valid-split para especificar una división de validación en tus datos.
Tipos de Tareas
Clasificación
Predecir etiquetas categóricas:
aitraining tabular --train \
--model xgboost \
--data-path ./customers.csv \
--target-columns churn \

Regresión
Predecir valores continuos:
aitraining tabular --train \
--model xgboost \
--data-path ./houses.csv \
--target-columns price \
--valid-split validation \
--task regression \
--project-name price-predictor
