Online Multi Task Gradient Temporal Difference Learning The temporal difference methods td (λ) and sarsa (λ) form a core part of modern reinforcement learning. their appeal comes from their good performance, low computational cost, and their simple interpretation, given by their forward view. Download citation | online multi task gradient temporal difference learning | we develop an online multi task formulation of model based gradient temporal difference (gtd). Building upon this approach, which is known as the efficient lifelong learning algorithm (ella), we develop an online mtl formulation of model based gradient temporal difference (gtd) reinforcement learning (sutton, szepesvári, and maei 2008). In this work, we combine these two lines of attack, deriving parameter free, gradient based temporal difference algorithms. our algorithms run in linear time and achieve high probability convergence guarantees matching those of gtd2 up to log factors.

Bibliographic details on online multi task gradient temporal difference learning. We empirically investigate tdrc across a range of problems, for both prediction and control, and for both linear and non linear function approximation, and show, potentially for the first time, that gradient td methods could be a better alternative to td and q learning. We propose the online attentive kernel based temporal difference (oaktd) algorithm, which employs two timescale optimization, and provide a convergence analysis for our proposed algorithm. The central goal of this paper is to find mitigation strategies against unweighted datasets to improve multi task learning performance. one issue with multi task learning is that gradients from different tasks can destructively interfere.
