Una baseline es un modelo, puntuación, proceso o resultado de referencia utilizado para juzgar si un sistema más complejo ofrece una mejora. En aprendizaje automático, una baseline ayuda a definir el rendimiento mínimo esperado que un nuevo modelo debería superar para justificar complejidad o coste adicionales.
A model used as a reference point for comparing how well another model (typically, a more complex one) is performing. For example, a logistic regression model might serve as a good baseline for a deep model. For a particular problem, the baseline helps model developers quantify the minimal expected performance that a new model must achieve for the new model to be useful.
