While data scientists were no longer handling Hadoop-sized workloads, they were trying to build predictive models on a different kind of “large” dataset: so-called “unstructured data.” ” There’s as much Keras, TensorFlow, and Torch today as there was Hadoop back in 2010-2012. And it was good.

Now that the class imbalance has been resolved, we can move forward with the actual model training. Model training. First, we define a function that will perform a grid search for the optimal hyperparameters of the classifier. In highly unbalanced datasets this interpretation could lead to poor predictions.

We have many routine analyses for which the sparsity pattern is closer to the nested case and lme4 scales very well; however, our prediction models tend to have input data that looks like the simulation on the right. Compact approximations to bayesian predictive distributions." Cambridge University Press, (2012). [4]
