Accordingly, optimization of hyperparameters is not necessary, as the number of neurons stems directly from the dimensionality of the data, further improving the algorithmic speed. Under this setting, overfitting is inherently avoided, and the results are interpretable and reproducible. The complexity ...
I used one written in Lisp, and a bunch of people at that time were using Theano, which was written in Python. So it was a healthy mix of things, and these were tiny projects, mostly developed by a couple of grad students in their free time kind of thing. Then the year after I ...
Optimizing parameterized quantum circuits is a key routine in using near-term quantum devices. However, the existing algorithms for such optimization require an excessive number of quantum-measurement shots for estimating expectation values of observable
