we calculate the stopping power for heavy-ion diclusters moving in a strongly coupled two-dimensional electron gas system by using the local field corrected dielectric function at finite temperature. we obtain a parameterized local field correction factor based on a relation between the thermal compressibility and exchange-correlation energy in two-dimension. the interpolated parameter is deriv...

Validation can be used to detect when overrtting starts during supervised training of a neural network; training is then stopped before convergence to avoid the overrtting (\early stopping"). The exact criterion used for validation-based early stopping, however, is usually chosen in an ad-hoc fashion or training is stopped interactively. This trick describes how to select a stopping criterion i...

We test Einstein’s theory of the photoelectric effect, which predicts a linear relation between the energy of light incident on a metal surface and the energy of the emitted electrons. We determine the electron stopping voltage as a function of frequency of incident radiation by illuminating a potassium cathode and constraining the wavelength of incident radiation using several optical band-pas...

Evolutionary Learning Classifier Systems (LCSs) are rule based systems that have been used effectively in concept learning. XCS is a prominent LCS that uses genetic algorithms and reinforcement learning techniques. In traditional machine learning, early stopping have been investigated extensively to an extent that it is now a default mechanism in many systems. There has been a belief that EC me...
