本文属于第三种,在 pairwise learning 这一 setting中研究 SGD和 online gradient descent。所以首先我们必须要来了解一下这个 pairwise learning 的设定和其背后的 motivation。 在一类机器学习问题中,我们的 loss function 具有pairwise的结构,即 n 个data 构成的 n(n−1)2 个pair,每一个pair贡献一个loss...
Although several algorithms have been proposed in literature, they are neither computationally efficient due to their intensive budget maintenance strategy nor effective due to the use of simple Perceptron algorithm. To overcome these limitations, we propose a framework for bounded kernel-based online ...

This paper considers the least-square online gradient descent algorithm in a reproducing kernel Hilbert space (RKHS) without an explicit regularization term. We present a novel capacity independent approach to derive error bounds and convergence results for this algorithm. The essential element in our ...
In particular, our interest is the performance of drift estimation as the convergence guarantee of the estimation by the online gradient descent algorithm needs large nh2, which is not required in batch estimation for drift parameters or batch/online estimation for diffusion parameters. We show the ...
BSGD-R budgeted SGD algorithm which extends the Pegasos algorithm (Shalev-Shwartz et al. 2007) by introducing a removal strategy for support vector budget maintenance (Wang et al. 2012). FOGD Fourier online gradient descent algorithm that applies the random Fourier features for approximating kernel...
We present an adaptive online gradient descent algorithm to solve online convex optimization problems with long-term constraints , which are constraints that need to be satisfied when accumulated over a finite number of rounds T , but can be violated in intermediate rounds. For some user-defined ...
