deep networks with internal selective attention through feedback connections
Neural Information Processing Systems, 2014Co-Authors: Marijn F Stollenga, Faustino Gomez, Jonathan Masci, Jurgen SchmidhuberAbstract:Traditional convolutional neural networks (CNN) are stationary and feedforward. They neither change their parameters during evaluation nor use feedback from higher to lower layers. Real brains, however, do. So does our Deep Attention Selective Network (dasNet) architecture. DasNet's feedback structure can dynamically alter its convolutional filter sensitivities during classification. It harnesses the power of sequential processing to improve classification performance, by allowing the network to iteratively focus its internal attention on some of its convolutional filters. Feedback is trained through direct policy search in a huge million-dimensional parameter space, through scalable Natural Evolution strategies (SNES). On the CIFAR-10 and CIFAR-100 datasets, dasNet outperforms the previous state-of-the-art model on unaugmented datasets.

Natural Evolution strategies
Journal of Machine Learning Research, 2014Co-Authors: Daan Wierstra, Tom Schaul, Yi Sun, Jan Peters, Tobias Glasmachers, Jurgen SchmidhuberAbstract:This paper presents Natural Evolution Strategies (NES), a recent family of black-box optimization algorithms that use the Natural gradient to update a parameterized search distribution in the direction of higher expected fitness. We introduce a collection of techniques that address issues of convergence, robustness, sample complexity, computational complexity and sensitivity to hyperparameters. This paper explores a number of implementations of the NES family, such as general-purpose multi-variate normal distributions and separable distributions tailored towards search in high dimensional spaces. Experimental results show best published performance on various standard benchmarks, as well as competitive performance on others.

a linear time Natural Evolution strategy for non separable functions
Genetic and Evolutionary Computation Conference, 2013Co-Authors: Yi Sun, Tom Schaul, Faustino Gomez, Jurgen SchmidhuberAbstract:We present a novel Natural Evolution Strategy (NES) variant, the Rank-One NES (R1-NES), which uses a low-rank approximation of the search distribution covariance matrix. The algorithm allows computation of the Natural gradient with cost linear in the dimensionality of the parameter space, and excels in solving high-dimensional non-separable problems.

efficient Natural Evolution strategies
arXiv: Artificial Intelligence, 2012Co-Authors: Yi Sun, Tom Schaul, Daan Wierstra, Jurgen SchmidhuberAbstract:Efficient Natural Evolution Strategies (eNES) is a novel alternative to conventional Evolutionary algorithms, using the Natural gradient to adapt the mutation distribution. Unlike previous methods based on Natural gradients, eNES uses a fast algorithm to calculate the inverse of the exact Fisher information matrix, thus increasing both robustness and performance of its Evolution gradient estimation, even in higher dimensions. Additional novel aspects of eNES include optimal fitness baselines and importance mixing (a procedure for updating the population with very few fitness evaluations). The algorithm yields competitive results on both unimodal and multimodal benchmarks.

Natural Evolution from idiopathic photosensitive occipital lobe epilepsy to idiopathic generalized epilepsy in an untreated young patient
Brain & Development, 2014Co-Authors: Francesca Bonini, Gabriella Egeo, Jinan Fattouch, Martina Fanella, Alessandra Morano, Anna Teresa Giallonardo, Carlo Di BonaventuraAbstract:Abstract Idiopathic photosensitive occipital lobe epilepsy (IPOE) is an idiopathic localization-related epilepsy characterized by age-related onset, specific mode of precipitation, occipital photic-induced seizures – frequently consisting of visual symptoms – and good prognosis. This uncommon epilepsy, which usually starts in childhood or adolescence, has rarely been observed in families in which idiopathic generalized epilepsy also affects other members. We describe a nuclear family in which the proband showed electro-clinical features of idiopathic photosensitive occipital lobe epilepsy in childhood, which subsequently evolved into absences and a single generalized tonico-clonic seizure in early adolescence. His mother had features suggestive of juvenile myoclonic epilepsy. This case illustrates a continuum between focal and generalized entities in the spectrum of the so-called idiopathic (genetically determined) epileptic syndromes.

community based palliative care the Natural Evolution for palliative care delivery in the u s
Journal of Pain and Symptom Management, 2013Co-Authors: Arif H Kamal, David C Currow, Christine S Ritchie, Janet Bull, Amy P AbernethyAbstract:Abstract Palliative care in the U.S. has evolved from a system primarily reliant on community-based hospices to a combined model that includes inpatient services at most large hospitals. However, these two dominant approaches leave most patients needing palliative care—those at home (including nursing homes) but not yet ready for hospice—unable to access the positive impacts of the palliative care approach. We propose a community-based palliative care (CPC) model that spans the array of inpatient and outpatient settings in which palliative care is provided and links seamlessly to inpatient care; likewise, it would span the full trajectory of advanced illness rather than focusing on the period just before death. Examples of CPC programs are developing organically across the U.S. As our understanding of CPC expands, standardization is needed to ensure replicability, consistency, and the ability to relate intervention models to outcomes. A growing body of literature examining outpatient palliative care supports the role of CPC in improving outcomes, including reduction in symptom burden, improved quality of life, increased survival, better satisfaction with care, and reduced health care resource utilization. Furthermore the examination of how to operationalize CPC is needed before widespread implementation can be realized. This article describes the key characteristics of CPC, highlighting its role in longitudinal care across patient transitions. Distinguishing features include consistent care across the disease trajectory independent of diagnosis and prognosis; inclusion of inpatient, outpatient, long-term care, and at-home care delivery; collaboration with other medical disciplines, nursing, and allied health; and full integration into the health care system (rather than parallel delivery).
