Adaptive learning in the presence of noise

Adaptive learning in the presence of noise – The problem of learning from high-dimensional data is studied in the context of probabilistic inference, which in turn involves learning probability distributions from large numbers of items. This task can be considered as the problem of learning from a sparse representation of an input, and with a high probability in the direction of inference, in order to achieve high inference accuracy. Despite this fact, low-dimensional data often exhibit high probability in the direction of inference, which indicates that a learning problem can have a high-confidence bias. In this paper, we propose a deep learning algorithm to learn a Bayesian inference problem from both a very sparse representation of an input and the posterior distribution of the input. Our work has been validated on several datasets and we show that it improves performance of our algorithm by reducing the number of labeled items by a factor of up to ~1x-$O$.

Non-parametric sparse coding (NSCC) is an efficient sparse coding algorithm for sparse coding which has been extensively studied in the literature. Although NSCC works well for many real-world problems, its simplicity and high computational complexity makes it difficult to learn the code to solve these problems. In this paper, we demonstrate that NSCC, using a sparse coding algorithm, can be solved to the best of our knowledge without any sparsity and by a single sparse coding algorithm in two steps of learning. Moreover, we prove that the problem of learning a sparse coding algorithm to solve non-parametric sparse coding is NP-hard. The results show the effectiveness of NSCC, and we hope that this has not hampered the other methods to solve non-parametric sparse coding.
