The Details About the presentation Conversation Join â¦ In this paper, we present a network and training strategy that relies on the strong use of data augmentation to use the available annotated samples more efficiently. A complete factorial experiment and the ScottâKnott method are used to find the best combination of factor levels, when the source of variation is statistically different in analysis of variance. The method is straightforward to implement At Crater Labs during the past year, we have been pursuing a research program applying ML/AI techniques to solve combinatorial optimization problems. Hence, in this study, we propose a review of existing literature devoted to such UAV path optimization problems, focusing specifically on the sub-class of problems that consider the mobility on a macroscopic scale. At the same time, although many new algorithms, such as genetic algorithms [20], can be used to solve conditioning optimization problems, it is also hard for them to obtain the optimum solution in a reasonable time in large-scale instances, and these algorithms also do not guarantee the accuracy of the solution theoretically.
