Gradient Ascent Subjective Multimedia Quality Testing
Subjective testing is the most direct means of assessing multimedia quality as experienced by users. When multiple dimensions must be evaluated, these tests can become slow and costly. We present gradient ascent subjective testing (GAST) as an efficient way to locate optimizing sets of coding or transmission parameter values. GAST combines gradient ascent optimization techniques with subjective...
متن کاملGradient Ascent Critic Optimization
In this paper, we address the critic optimization problem within the context of reinforcement learning. The focus of this problem is on improving an agent’s critic, so as to increase performance over a distribution of tasks. We use ordered derivatives, in a process similar to back propagation through time, to compute the gradient of an agent’s fitness with respect to its reward function. With e...
متن کاملComparing subjective video quality testing methodologies
International recommendations for subjective video quality assessment (e.g., ITU-R BT.500-11) include specifications for how to perform many different types of subjective tests. Some of these test methods are double stimulus where viewers rate the quality or change in quality between two video streams (reference and impaired). Others are single stimulus where viewers rate the quality of just on...
متن کاملReward Design via Online Gradient Ascent
Recent work has demonstrated that when artificial agents are limited in their ability to achieve their goals, the agent designer can benefit by making the agent’s goals different from the designer’s. This gives rise to the optimization problem of designing the artificial agent’s goals—in the RL framework, designing the agent’s reward function. Existing attempts at solving this optimal reward pr...
متن کاملTowards a comparable and reproducible subjective outdoor multimedia quality assessment
For a long time, subjective multimedia quality assessment has been performed in dedicated laboratories according to well known standards. However, the consumption mode of multimedia content and applications has significantly changed during the last years. Currently, the users’ context is subject to more variations than in previous times where users were sitting on their sofa watching television...
