Multilayer Neural Network with Synapse Based on Two Successive Memristors

Introduction: Synapse based on two successive memristors builds the synaptic weights of the artificial neural network for training three-bit parity problem and five-character recognition. Methods: The proposed memristor synapse circuit creates positive weights in the range [0;1], and maps it to range [-1;1] to program both the positive and negative weights. The proposed scheme achieves the same accuracy rate as the conventional bridge synapse schemes which consist of four memristors. Results and Conclusion: However, proposed synapse circuit decreases 50% the number of memristors and 76.88% power consumption compared to the conventional bridge memristor synapse.

Could God Fail to Exist?

I apply developments in modal reasoning to the question of whether God has necessary existence. My larger task is to assess the main reasons to think that God is not a metaphysically necessary being. I consider Hume’s conceivability-based argument, and then I pay attention to more recent arguments, including Swinburne’s neo-Humean argument and the subtraction argument. I show that such arguments face a ‘parity’ problem, since the very reasoning that gets them off the ground also launches parallel arguments for an opposite conclusion. In my closing section, I sketch an argument schema designed to illustrate a new, general strategy for deducing the necessary existence of God by building upon recent modal cosmological arguments.

How Democratic Alliances Solve the Power Parity Problem

Why do challengers attack some states that have allies, while avoiding conflict with others? This article builds upon previous research by arguing that parity in the observable capabilities of opposing states and their allies generates greater uncertainty and miscalculations on the part of challengers, which leads to a higher probability of conflict. Unlike previous research, however, this article argues that military alliances among democracies are better able to overcome this uncertainty, making power distributions largely irrelevant. The results demonstrate that uncertainty generated at power parity is mitigated when a target state’s allies are more democratic, resulting in no overall change in the probability of conflict. This study therefore emphasizes that the effectiveness of military alliances lies not necessarily in their aggregation of power, but in their ability to co-ordinate their power and communicate this co-ordination to potential challengers.
