Machine learning and Information Theory are two broad research areas with strong connections. In this presentation, we will cover two topics that explore de use of information-theoretic measures in learning. On the first topic, we will present results that show how adequate the adoption of mutual information is for predicting the operational quality of a transformation (or encoder) in classification. These results offer new insights into adopting information measures in machine learning,  like mutual information and cross-entropy. For the second topic, we will discuss the idea of information sufficiency, representing a model's latent structure, and explore a non-parametric data-driven method to detect this type of structure from data. We will focus on the learning-decision task of testing independence using a non-parametric mutual information estimator. We present non-asymptotic and asymptotic results that support the advantage of this approach and elaborate on applications for learning data structure and model-change detection.
