SVM is a kernel-based algorithm. Akernelis a function that transforms the input data to a high-dimensional space where the problem is solved. Kernel functions can be linear or nonlinear. Oracle Machine Learning for SQLsupports linear and Gaussian (nonlinear) kernels. ...
Transfer Learning by Kernel Meta-Learning 来自 钛学术 喜欢 0 阅读量: 41 作者: F Aiolli 摘要: A crucial issue in machine learning is how to learn appropriate representations for data. Recently, much work has been devoted to kernel learning, that is, the problem of finding a good kernel ...
Based on recent results from classical machine learning, we prove that linear quantum models must utilize exponentially more qubits than data re-uploading models in order to solve certain learning tasks, while kernel methods additionally require exponentially more data points. Our results provide a ...
