As one of the most fundamental stochastic optimization algorithms, stochastic gradient descent (SGD) has been intensively developed and extensively applied in machine learning in the past decade. There have been some modified SGD-type algorithms, which outperform the SGD in many competitions and app…
Understanding convergence of SGD-based optimization algorithms can help deal with enormous machine learning problems. To ensure last-iterate convergence of SGD and momentum-based SGD (mSGD), the existing studies usually constrain the step size $\epsilon_{n}$ to decay as $\sum_{n=1}^{+\infty}\ep…
A novel robust and slip-aware speed estimation framework is developed and experimentally verified for mobile robot navigation by designing proprioceptive robust observers at each wheel. The observer for each corner is proved to be consistent, in the sense that it can provide an upper bound of the me
