Estimating Nonstationary Variables via the Kernel Lasso – We explore the use of the kernel Lasso to estimate the unknown covariance matrix for nonstationary covariance matrices and its estimation using the kernel Lasso. We propose a new algorithm called Kernel Lasso (KL) that takes the unknown covariance matrix as an input and optimizes a Kernel Lasso by minimizing the covariance matrices. This algorithm is evaluated on two datasets: the MNIST and CIFAR-10 datasets. By comparing two K-Samples, we identify that there are three types of covariance matrices with the kernel Lasso. We discuss the learning algorithm in the experiments to understand the performance of this algorithm, and we show that it can be used to infer the kernel covariance matrix of the unknown covariance matrix.
As a major challenge in machine learning, a significant number of machine learning tasks use a low-dimensional representation of the data. It is hard to directly optimize the representation by training the deep network on a high-dimensional representation. In this paper, we propose a novel non-linear learning algorithm for model-based decision support for deep networks, wherein the high-dimensional representations of the data are optimized using a weighted least-squares loss to the loss function as well as a non-linear learning objective. Our algorithm is based on a simple yet effective regularization term which is efficient and practical, but requires no supervision for the deep network. The algorithm is applied to support the decision support task in which the input data of both data types for various decision contexts is shared (e.g. from the medical record, to users of healthcare services). In case of data sharing, it is also possible to compute weighted least-squares loss functions such that the data of different types are not shared by all models for a set of multiple decision contexts. We demonstrate the effectiveness of the proposed algorithm in two real and real-world scenarios.
