WebJul 25, 2024 · Abstract. Intrinsic plasticity, as a biologically inspired unsupervised learning rule, is used for adapting the intrinsic excitability of the reservoir neurons. Existing intrinsic plasticity rules can only select a set of fixed rule parameters for the whole reservoir neurons, which affects the learning performance due to the lack of flexibility ... WebThe intrinsic plasticity or brittleness of crystalline metals correlates with the ratio of the elastic shear modulus μ to the bulk modulus B; when the ratio μ/B exceeds a critical value, the metal is brittle. Sufficient data on elastic moduli and toughness are now available to permit an assessment for metallic glasses. the george and dragon hotel https://speconindia.com
