Education
- Diploma in Data ScienceICARO2024En este curso dictado por ICARO, aprendí a usar Scikit Learn, librería esencial para llevar adelante modelos de machine learning. Me introduje en el aprendizaje automático mediante aplicaciones como regresión lineal y clasificación. Empleando algoritmos como KNN y decisión TREES. Implementare modelos avanzados como SVM, redes neuronales, ensambles. Además de técnicas como BAGGING y BOOSTING. Y por último aprendí a dejar disponibles los modelos mediante APIs, además de emplear herramientas de computación en la nube.
