Task specialization across research careers

Research careers are typically envisioned as a single path in which a scientist starts as a member of a team working under the guidance of one or more experienced scientists and, if they are successful, ends with the individual leading their own research group and training future generations of scientists. Here we study the author...

Calibrating experts’ probabilistic assessments for improved probabilistic predictions

Expert judgement is routinely required to inform critically important decisions. While expert judgement can be remarkably useful when data are absent, it can be easily influenced by contextual biases which can lead to poor judgements and subsequently poor decisions. Structured elicitation protocols aim to: (1) guard against biases and provide...

Bayesian networks for identifying incorrect probabilistic intuitions in a climate trend uncertainty quantification context

Probabilistic thinking can often be unintuitive. This is the case even for simple problems, let alone the more complex ones arising in climate modelling, where disparate information sources need to be combined. The physical models, the natural variability of systems, the measurement errors and their dependence upon the observational period...

Comparison of Logistic Regression and Bayesian Networks for Risk Prediction of Breast Cancer Recurrence

Purpose. For individualized follow-up, accurate prediction of locoregional recurrence (LRR) and second primary (SP) breast cancer risk is required. Current prediction models employ regression, but with large data sets, machine-learning techniques such as Bayesian Networks (BNs) may be better alternatives. In this study, logistic regression...

Predicting the age of researchers using bibliometric data

The age of researchers is a critical factor necessary to study the bibliometric characteristics of the scholars that produce new knowledge. In bibliometric studies, the age of scientific authors is generally missing; however, the year of the first publication is frequently considered as a proxy of the age of researchers. In this article, we...

Parallel Matrix Multiplication on Memristor-Based Computation-in-Memory Architecture

One of the most important constraints of today’s architectures for data-intensive applications is the limited bandwidth due to the memory-processor communication bottleneck. This significantly impacts performance and energy. For instance, the energy consumption share of communication and memory<br/>access may exceed 80%. Recently, the concept of...

Skeleton-based design and simulation flow for Computation-in-Memory architectures

Memristor-based Computation-in-Memory is one of the emerging architectures proposed to deal with Big Data problems. The design of such architectures requires a radically new automatic design flow because the memristor is a passive device that uses resistance to encode its logic value. This paper proposes a design flow for mapping parallel...

Automatic Hardware Generation for Reconfigurable Architectures

Reconfigurable Architectures (RA) have been gaining popularity rapidly in the last decade for two reasons. First, processor clock frequencies reached threshold values past which power dissipation becomes a very difficult problem to solve. As a consequence, alternatives were sought to keep improving the system performance. Second, because Field...

Shape Constrained Nonparametric Estimation in the Cox Model

The events of interest in any survival analysis study are regularly subject to censoring. There are various censoring schemes, including right or left censoring, and interval censoring. The most frequent censoring scheme is the right censoring, where subjects might drop out of the study or simply because not all events of interest occur before...
