We analyze the memory mechanism of XCSM, the extension of XCS with internal memory. Our aim is to explain some of the results reported in the literature, which show that XCSM fails to learn an optimal policy in complex partially observable environments. The analysis we present reveals that the XCSM’s memory management strategy cannot guarantee the convergence to an optimal solution. We thus ext...

In this paper, we discuss regression analysis of bivariate interval-censored failure time data that often occur in biomedical and epidemiological studies. To solve problem, propose a kind general flexible copula-based semiparametric partly linear additive hazards models can allow for both time-dependent covariates possible nonlinear effects. For inference, sieve maximum likelihood estimation ap...
