Query: Online Deterministic Annealing for Classification and Clustering   Inherent in virtually every iterative machine learning algorithm is the
problem of hyper-parameter tuning, which includes three major design
parameters: (a) the complexity of the model, e.g., the number of neurons in a
neural network, (b) the initial conditions, which heavily affect the behavior
of the algorithm, and (c) the dissimilarity measure used to quantify its
performance. We introduce an online prototype-based learning algorithm that can
be viewed as a progressively growing competitive-learning neural network
architecture for classification and clustering. The learning rule of the
proposed approach is formulated as an online gradient-free stochastic
approximation algorithm that solves a sequence of appropriately defined
optimization problems, simulating an annealing process. The annealing nature of
the algorithm contributes to avoiding poor local minima, offers robustness with
respect to the initial conditions, and provides a means to progressively
increase the complexity of the learning model, through an intuitive bifurcation
phenomenon. The proposed approach is interpretable, requires minimal
hyper-parameter tuning, and allows online control over the
performance-complexity trade-off. Finally, we show that Bregman divergences
appear naturally as a family of dissimilarity measures that play a central role
in both the performance and the computational complexity of the learning
algorithm.
