Analogical Dissimilarity: Algorithm, and A Parameter-Free Algorithm for Convex Composite Problems – In this paper we propose a Bayesian algorithm to solve a wide range of complex optimization problems, including the generalization of Gaussian processes. The method is designed so that the proposed algorithm performs efficiently and not at the cost of any high-dimensional optimization problem. In particular, it is designed to achieve a new performance measure, which can be used for computing the expected value of a parametrized function. We also show that the proposed algorithm can be implemented as a Bayesian algorithm and show the efficiency of the proposed algorithm by comparing the performance of the proposed algorithm with the performance of other Bayesian algorithms. In addition, we also show that the Bayesian algorithm can be decomposed into two Bayesian algorithms to solve many types of complex optimization problems. The results are useful for applications such as the problem of finding the optimal function, for predicting the solution of a complex function, or for generalizing a particular feature learning algorithm.
We study the problem of constructing a semantic data model from low-dimensional sparse data using a random walk approach to the problem. The goal is to recover a high-dimensional vector space from data using a sparse model. We consider a set of datasets, where the model is modeled using a stochastic optimization, and the data is generated using a sparse solution. This is accomplished via a greedy optimization followed by a sequential search that optimizes a small local optimizer and the global optimizer. This solution is consistent with the low level representation of the data and the observation that the resulting model is efficient and robust to noise. We show that this approach is equivalent to minimizing a small subset of the entries of a deep network, provided the global optimizer returns results that are consistent with the low level representation of the data. Experiments in both synthetic data and real data show that the proposed approach can be effective for learning in a sparse dataset with arbitrary data and noise conditions.
