Memristor Neural Network Design
Neural network, a powerful learning model, has archived amazing results. However, the current Von Neumann computing systemâbased implementations of neural networks are suffering from memory wall and communication bottleneck problems ascribing to the Complementary Metal Oxide Semiconductor (CMOS) technology scaling down and communication gap. Memristor, a two terminal nanosolid state nonvolatile resistive switching, can provide energyâefficient neuromorphic computing with its synaptic behavior. Crossbar architecture can be used to perform neural computations because of its high density and parallel computation. Thus, neural networks based on memristor crossbar will perform better in real world applications. In this chapter, the design of different neural network architectures based on memristor is introduced, including spiking neural networks, multilayer neural networks, convolution neural networks, and recurrent neural networks. And the brief introduction, the architecture, the computing circuits, and the training algorithm of each kind of neural networks are presented by instances. The potential applications and the prospects of memristorâbased neural network system are discussed
The curriculum reform of CAD graphic design for combining theory and practice
As a tool course, CAD graphic design in engineering is assisting other professional courses to achieve professional training goals. According to the characteristics and existing problems of CAD graphic design, this paper puts forward some constructive measures to connect the course with practice application and improve the studentsâ learning enthusiasm. The proposed measures include: teaching method combining theory with practice, teaching mode containing "teaching" and "learning" content, the matched evaluation mechanism guiding correctly students to learn
Equilibrium price and optimal insider trading strategy under stochastic liquidity with long memory
In this paper, the Kyle model of insider trading is extended by
characterizing the trading volume with long memory and allowing the noise
trading volatility to follow a general stochastic process. Under this newly
revised model, the equilibrium conditions are determined, with which the
optimal insider trading strategy, price impact and price volatility are
obtained explicitly. The volatility of the price volatility appears excessive,
which is a result of the fact that a more aggressive trading strategy is chosen
by the insider when uninformed volume is higher. The optimal trading strategy
turns out to possess the property of long memory, and the price impact is also
affected by the fractional noise.Comment: 21 pages; 2 figure
