Spline trajectory

WebThe transformer model is trained to predict accurate time allocations with fewer data samples and smaller model size, compared to a feedforward network, demonstrating that it is able to model the sequential nature of the waypoint navigation problem. In this work, we address the problem of computation time for trajectory generation in quadrotors. Most … WebObjectives: The life event of retirement may be associated with changes in levels of depressive symptoms. The use of polynomial group-based trajectory modelling allows any changes to vary between different groups in a sample. A new approach, estimating these models using B-splines rather than polynomials, may improve modelling of complex …
