Efficient Online Convex Optimization with a Non-Convex Cost Function


Efficient Online Convex Optimization with a Non-Convex Cost Function – In this paper, we study the use of Bayesian networks, which is a type of optimization algorithm, for solving a class of problems where several functions can be defined and the objective is to achieve a given bound that matches the probability density function. The problem uses a simple model of the input space, and it may be solved using any other suitable optimization criterion. Our first contribution is to model how Bayesian networks work, and we describe a method of learning the optimal parameters based on Bayesian networks with a nonconvex cost function. We demonstrate the usefulness of this method in our experiments for several important problems (e.g., cross validation and machine learning), that can be posed as a constraint satisfaction problem. We further develop Bayesian networks on the same problems, and demonstrate how the proposed approach can be used to solve the common problems in machine learning and finance.

The problem of generating a given model in high-dimensional space is of primary importance. In this paper we propose a novel general purpose learning algorithm for optimizing the joint probability density function of a model. The joint probability function is an important parameter in high-dimensional probabilistic modelling, which we define as a distribution over the joint probability densities of the model. Based on this generalization we present a new dimension-reducing learning algorithm, called Joint Probabilistic Regret Optimization. At each iteration we use a high-dimensional discrete-valued probability density function to generate new labels, and compute a joint probability density function that captures the joint posterior information. Our method achieves state-of-the-art performance on real world data sets of three domains: real world data, biomedical data and synthetic data.
