TNCOA: Efficient Exploration via Observation‐Action Constraint on Trajectory‐Based Intrinsic Reward

open access: yesCAAI Transactions on Intelligence Technology, EarlyView.
ABSTRACT Efficient exploration is critical in handling sparse rewards and partial observability in deep reinforcement learning. However, most existing intrinsic reward methods based on novelty rely on single‐step observations or Euclidean distances.

Modeling micro-macro pedestrian counterflow in heterogeneous domains [PDF]

open access: yes, 2010
We present a micro-macro strategy able to describe the dynamics of crowds in heterogeneous media. Herein we focus on the example of pedestrian counterflow. The main working tools include the use of mass and porosity measures together with their transport

Temporal Dependency‐Aware Trajectory‐Level Behavioural Metric for Exploration in Reinforcement Learning

open access: yesCAAI Transactions on Intelligence Technology, EarlyView.
ABSTRACT Intrinsic motivation serves as the predominant paradigm of exploration in reinforcement learning. In pursuit of an informative and robust state representation, the behavioural metric groups behaviourally equivalent states together, which share the same single‐step reward and transition distribution.

A Scoping Review of Certified Nurse‐Midwife and Certified Midwife Care in the United States: Assessing Outcomes Across Six Patient Care Domains

open access: yesThe Milbank Quarterly, EarlyView.
Policy Points Certified nurse‐midwife (CNM)/certified midwife (CM) care is associated with outcomes that are comparable or improved compared to physician care across multiple domains of health care quality, especially safety and effectiveness. CNM/CM care is consistently associated with lower rates of intrapartum interventions and improved birth ...

Lean interfaces for integrated catchment management models: rapid development using ICMS

open access: yes, 2002
A move towards the development of lean, issue-focused interfaces is being explored to provide a rapid delivery mechanism to transfer catchment science to managers and custodians.

Assessing the Utility and Safety of Intravenous Iodinated Contrast Media in CT ‘Pan Scan’ Studies in Geriatric Patients Following Low‐Energy Blunt Trauma

open access: yesJournal of Medical Imaging and Radiation Oncology, EarlyView.
ABSTRACT Introduction Ground level falls are common in the geriatric population, often culminating in Emergency Department attendance and a CT ‘pan scan’. These scans are routinely performed with intravenous iodinated contrast media (ICM). The types of injuries identified in this cohort can often be adequately characterised without ICM.

Fiscal impulse in the Brazilian economy [PDF]

open access: yes
This paper develops an alternative indicator of fiscal policy which allows a more accurate picture of the underlying fiscal trend in the Brazilian economy over the recent period. This indicator corrects conventional fiscal-stance measures for the effects

Harnessing iEcology data to uncover invasive species behaviour

open access: yesMethods in Ecology and Evolution, EarlyView.
Abstract Invasive animal species threaten ecosystems, biodiversity and human livelihoods. Behavioural traits such as boldness, exploratory tendencies, learning ability and social interactions are known to influence invasion success. Yet these behavioural traits remain underexplored due to challenges in observing behaviour across large spatial and ...
