Design Strategies of Capacitor‐Based Synaptic Cell for High‐Efficiency Analog Neural Network Training

open access: yesAdvanced Intelligent Systems, EarlyView.
This work explores the three‐transistors‐one‐capacitor synaptic cell design for analog in‐memory computing, focusing on improving performance and scalability in deep neural network (DNN) training. By optimizing transistor characteristics and proposing a novel cell design, challenges such as large cell areas and retention issues are addressed.

"Forecasting stochastic Volatility using the Kalman filter: an application to Canadian Interest Rates and Price-Earnings Ratio" [PDF]

open access: yes
In this paper, we aim at forecasting the stochastic volatility of key financial market variables with the Kalman filter using stochastic models developed by Taylor (1986,1994) and Nelson (1990).

Asymptotic Analysis for One-Name Credit Derivatives

open access: yesAbstract and Applied Analysis, 2013
We propose approximate solutions to price defaultable zero-coupon bonds as well as the corresponding credit default swaps and bond options. We consider the intensity-based approach of a two-correlated-factor Hull-White model with stochastic volatility of

Bias‐Independent True Random Number Generator Circuit using Memristor Noise Signals as Entropy Source

open access: yesAdvanced Intelligent Systems, EarlyView.
Random telegraph noise (RTN) characteristics of memristor depend on external environmental conditions. To avoid these bias‐dependent characteristics, a true random number generator circuit using the RTN current fluctuations of memristor is presented with an edge detection circuit and counter, and bias independence is experimentally demonstrated for ...

Large deviations for fractional volatility models with non-Gaussian volatility driver [PDF]

open access: yesarXiv, 2020
We study stochastic volatility models in which the volatility process is a function of a continuous fractional stochastic process, which is an integral transform of the solution of an SDE satisfying the Yamada-Watanabe condition. We establish a small-noise large deviation principle for the log-price, and, for a special case of our setup, obtain ...

Extensions of Dupire Formula: Stochastic Interest Rates and Stochastic Local Volatility

open access: yes, 2020
We derive generalizations of Dupire formula to the cases of general stochastic drift and/or stochastic local volatility. First, we handle a case in which the drift is given as difference of two stochastic short rates. Such a setting is natural in foreign

Stateful Full Adder Using Silicon Diodes

open access: yesAdvanced Intelligent Systems, EarlyView.
This simulation study presents stateful full adders comprising silicon p+–n–p–n+ diodes. The switching and bistable memory characteristics of the diodes enable full adder and bidirectional logic operation. An N‐bit full adder can be realized in a crossbar array using 9N + 1 diodes and 6 + 5N logic steps.
