Keras

Keras es la API de alto nivel para redes neuronales que permite pasar de la idea al experimento en minutos. Con su sintaxis declarativa –functional y subclassing– y el respaldo directo de TensorFlow, acelera tanto la investigación como la puesta en producción de modelos deep learning.

Itrion ha desplegado 275 modelos Keras en producción, abarcando visión, NLP y time‑series con un tiempo medio de prototipado de 48 h y SLA 99,9 %.
