Learning long-term temporal dependencies with recurrent neural networks can be a difficult problem. It has recently been shown that a class of recurrent neural networks called NARX networks perform much better than conventional recurrent neural networks for learning certain simple long-term dependency problems. The intuitive explanation for this behavior is that the output memories of a NARX ne...

Recurrent neural networks (RNNs) with jump ahead connections have been used in the computer vision tasks. Still, they have not been investigated well for automatic speech recognition (ASR) tasks. In other words, unfolded RNN has been shown to be an effective model for acoustic modeling tasks. This paper investigates how to elaborate a sophisticated unfolded deep RNN architecture in which recurr...

The paper is devoted to forecasting hourly day-ahead electricity prices from the perspective of existence jumps. We compare results different jump detection techniques and identify common features price apply jump-diffusion model with a double exponential distribution sizes explanatory variables. In order improve accuracy forecasts, we take into account time-varying intensity occurrences. forec...

This opportune case study describes visual and stepping behaviours of an 87 year old female (P8), both prior to, and following two falls. Before falling, when asked to walk along a path containing two stepping guides positioned before and after an obstacle, P8 generally visually fixated the first stepping guide until after foot contact inside it. However, after falling P8 consistently looked aw...

In this paper we analyze asset returns models with diffusion part and jumps in returns with stochastic volatility either from diffusion or pure jump part. We consider different specifications for the pure jump part including compound Poisson, Variance Gamma and Levy α-stable jumps. Monte Carlo Markov chain algorithm is constructed to estimate models with latent Variance Gamma and Levy α−stable ...

In the theory of diffusive acceleration at oblique shock fronts the question of the existence of a discontinuity of energetic particle density is contentious. The resolution of this problem is interesting from a theoretical point of view, and potentially for the interpretation of observations of particle densities at heliospheric shocks and of high-resolution radio observations of the rims of s...
