非负稀疏编码

Non-negative sparse coding

Patrik O. Hoyer

摘要:

非负稀疏编码是一种将多变量数据分解为非负稀疏分量的方法。在本文中,我们简要地描述了这种类型的数据表示背后的动机及其与标准稀疏编码和非负矩阵分解的关系。然后,我们给出了一个简单而有效的乘法算法找到最佳值的隐藏组件。此外,我们还展示了如何从观测数据中学习基向量。仿真结果表明了该方法的有效性。

英文摘要:

Non-negative sparse coding is a method for decomposing multivariate data into non-negative sparse components. In this paper we briefly describe the motivation behind this type of data representation and its relation to standard sparse coding and non-negative matrix factorization. We then give a simple yet efficient multiplicative algorithm for finding the optimal values of the hidden components. In addition, we show how the basis vectors can be learned from the observed data. Simulations demonstrate the effectiveness of the proposed method.
