在本文中，我们提出了一个忆阻STDP模型实现的原则，抑制Froemke和Dan的三重峰。所提出的模型声称与配对和三重STDP规则兼容，超越了基本忆阻STDP模型的限制。这种相容性是通过假设一种可变阈值适应突触增强（LTP）和抑制（LTD）的机制来实现的：前一个LTP对后一个LTD具有负面影响，相应的动力学过程由一组常微分方程来控制。它是原始抑制STDP模型的等效模型。的自适应阈值的关系，短期的可塑性。
In this paper, we propose a memristive STDP model realizing the principle of suppression of Froemke and Dan for triplet spikes. The proposed model claims compatibility with both the pair and triplet STDP rules, going beyond the limit of the basic memristive STDP model. The compatibility is realized by assuming a mechanism of variable thresholds adapting to synaptic potentiation (LTP) and depression (LTD): the preceding LTP has a negative influence on the following LTD. The corresponding dynamical process is governed by a set of ordinary differential equations. It is an equivalent model of the original suppression STDP model. A relation of the adaptive thresholds to short-term plasticity is addressed.
