2.1 Feature Engineering as the Bottleneck

Classical algorithms cannot automatically discover high-level features from raw data. For instance, in a housing price prediction model, the algorithm does not inherently know that "distance to the city center" is relevant unless the engineer creates that feature. Scikit-Learn shines in this phase through transformers like StandardScaler, OneHotEncoder, and custom Pipeline objects, ensuring reproducibility and preventing data leakage. aprende machine learning con scikitlearn keras y tensorflow

  • Validación cruzada (scikit-learn) o callbacks (Keras: EarlyStopping, ModelCheckpoint).
  • Ajuste de hiperparámetros: GridSearch/RandomizedSearch (scikit-learn) o Keras Tuner.
  • Keras/TensorFlow: construir DNNs, CNNs (visión), RNN/Transformers (texto). Usar tf.data para cargas eficientes.
