Abstract: A method for determination of a state of health indicator of an electrical accumulator includes converting a set of charge and discharge operations into an equivalent set of symmetrical reconstituted cycles and selecting the symmetrical reconstituted cycles. For each selected symmetrical reconstituted cycle the rate of energy supplied by the electrical accumulator during the discharge phase per unit of state of charge amplitude of the electrical accumulator and a total equivalent energy value for a complete charge of the electrical accumulator are determined. The method also includes determining a mean value from total equivalent energy values relating to a plurality of selected symmetrical reconstituted cycles and determining the state of health indicator of the electrical accumulator by dividing the mean value by the value of the nominal energy capacity of the electrical accumulator.

Abstract: The present invention concerns a method for programming a Bayesian neural network (BNN) in a RRAM memory. After the BNN has been trained on a dataset D, the joint posterior probability distribution of the synaptic coefficients, p(w|D) is decomposed into a mixture of multivariate mean-field Gaussian components by GMM. The weighting coefficients and the parameters of these multivariate Gaussian components are estimated by MDEM (Multi-Dimensional Expectation Maximization) with two constraints. According to the first constraint, the off-diagonal terms of the covariance matrix of each component are forced to zero. According to the second constraint, the couples of mean values and diagonal terms of the covariance matrix of each component are constrained to belong to a hardware compliance domain determined by a relationship between the conductance mean value and conductance standard deviation of a memristor programmed by a SET or RESET operation.
