A model for learning to segment temporal sequences, utilizing a mixture of RNN experts together with adaptive variance

This paper proposes a novel learning method for a mixture of recurrent neural network (RNN) experts model, which can acquire the ability to generate desired sequences by dynamically switching between experts. Our method is based on maximum likelihood estimation, using a gradient descent algorithm. This approach is similar to that used in conventional methods; however, we modify the likelihood function by adding a mechanism to alter the variance for each expert. The proposed method is demonstrated to successfully learn Markov chain switching among a set of 9 Lissajous curves, for which the conventional method fails. The learning performance, analyzed in terms of the generalization capability, of the proposed method is also shown to be superior to that of the conventional method. With the addition of a gating network, the proposed method is successfully applied to the learning of sensory–motor flows for a small humanoid robot as a realistic problem of time series prediction and generation.     

Socioeconomic inequalities in health dynamics: A comparison of Britain and the United States

Drawing on theory and research on the fundamental causes of health, the life course, and the welfare state, we investigate social inequalities in dynamic self-rated health for working-aged Britons and Americans. We use data from the British Household Panel Survey and Panel Study of Income Dynamics (1990–2004) and a mixture latent Markov model to test a theoretical model of health as a discrete state that may remain stable or change over time. Our contributions are threefold. First, our finding of three distinctive types of health processes (stable good health, stable poor health, and a “mover” health trajectory) represents a more differentiated profile of long-term health than previously shown. Second, we characterize health trajectories in structural terms by suggesting who was more likely to experience what type of health trajectory. Third, our more differentiated picture of dynamic health leads to a more nuanced understanding of comparative health: Although the health advantage of Britons was confirmed, our results also indicate that they were more likely to experience health change. Moreover, the socioeconomic gradient in long-term health was steeper in the US, raising provocative questions about how state policies and practices may affect population health.
