MPI—basics and blocking P2P communication MPI 是进程 (process) 级并行，process 间内存不共享，与线程 (thread) 级并行不同 https://mpitutorial.com/tutorials/ https://scc.ustc.edu.cn/_upload/article/files/e0/98/a9f0c...
Lecture: Learning Objectives The aim of this lecture is to design path planning for robot navigation. Objectives: Obstacle avoidance Search algo...
Regularisation We can prevent a too general model from overfitting through regularisation. We modify the loss function to include a penalty for too high parmeter: [J_{pen}(X,y.\vec w) = CJ(X,y,\...
Not all separable problems are linearly separable. A straight line in not the best decision boundary in many cases. Let’s look at a separable problem that can’t be linearly separated: If we try...
Learning Curves Using polynomial features for this dataset we achieved a good separation, but we wondered how well the model might generalise. Testing the model The data was generated accordi...
