WebAug 3, 2015 · We showed that using four different STDP rules together with lateral inhibition and homoeostasis, the resulting networks have a similar performance and show very stable learning over time. Especially the latter property is commonly hard to achieve since many networks tend to overfit the data, or lack mechanisms to prevent weights from growing ... WebFeb 28, 2024 · An asymmetric STDP function is required more than a symmetric STDP function to realize the neural network circuit. Considering the use of the double-level rectangular wave, as shown in Fig. 5, it is difficult to obtain asymmetric STDP characteristics. In this study, to realize an asymmetric STDP function, we used a triple … WebOct 15, 2024 · Engineering STDP In software as well as in hardware, STDP can be computed in many different ways. Here we follow an event-driven approach for both the software as well as the digital hardware implementation. This way, computations are not performed time-step by time-step, but only when an event is generated and transmitted. the medical city clinic araneta
