Web2. aug 2024 · Now, some of these features are very sparse (Active less than 10% of the time, with the rest as zeros). But the few times that these features are active may be really good predictors of the target. In most algorithms, these features will be mostly ignored due to how sparse they are - despite their predictive ability. Web11. apr 2024 · The dense reward may produce a misleading way for the agent to interpret the navigation tasks, which is why we decided to use a sparse reward instead. The agent’s reward function is designed in such a way that, by maximizing its reward, the agent will also identify the main tasks and achieve superior navigation performance [35] .

WebA sparse array is one that contains mostly zeros and few non-zero entries. A dense array contains mostly non-zeros.
