Artificial Delegates Resolve Fairness Issues in Perpetual Voting with Partial Turnout

Perpetual voting considers sequences of decis ions made by the same electorate, where fairness must be evaluated over time rather than perdecision [16]. A centralchallenge in this setting is ensuring adequaterepresentation for voters who are repeatedly in the minority. Traditional a ggregation rules, such as majority voting or Borda count, fail in this regard: they offer no guarantees of long-term fai rness or cumulative influence. In response, methods such as Perpetual Phragmén [17] and Perpetual Consensus [16] hav e been proposed to distribute influence more equitably over time. However, they rely on full knowledge of all voters ' approval sets, implicitly requiring consistent voter participation, a condition which can be hard to satisfy in real-world contexts. Real-world elections face various practical constraints-- including scheduling conflicts, limited resources, and restricted information access--that inevitably prevent vote rs from participating consistently.


Learning based on neurovectors for tabular data: a new neural network approach

--In this paper, we present a novel learning approach based on Neurovectors, an innovative paradigm that structures information through interconnected nodes and vector relationships for tabular data processing. Unlike traditional artificial neural networks that rely on weight adjustment through backpropagation, Neurovectors encode information by structuring data in vector spaces where energy propagation, rather than traditional weight updates, drives the learning process, enabling a more adaptable and explainable learning process. Our method generates dynamic representations of knowledge through neurovectors, thereby improving both the interpretability and efficiency of the predictive model. Experimental results using datasets from well-established repositories such as the UCI machine learning repository and Kaggle are reported both for classification and regression. T o evaluate its performance, we compare our approach with standard machine learning and deep learning models, showing that Neurovectors achieve competitive accuracy while significantly reducing computational costs. Machine learning has significantly advanced in recent decades, with models such as deep neural networks (DNNs), decision tree-based methods, and probabilistic models [1], [2], among others. Despite their widespread success, these approaches present limitations in terms of preprocessing requirements, interpretability, and computational efficiency. Deep neural networks have demonstrated remarkable performance in various domains--from computer vision to natural language processing [3].


Robust personnel rostering: how accurate should absenteeism predictions be?

Disruptions to personnel rosters caused by absenteeism often necessitate last-minute adjustments to the employees' working hours. A common strategy to mitigate the impact of such changes is to assign employees to reserve shifts: special on-call duties during which an employee can be called in to cover for an absent employee. To maximize roster robustness, we assume a predict-then-optimize approach that uses absence predictions from a machine learning model to schedule an adequate number of reserve shifts. In this paper we propose a methodology to evaluate the robustness of rosters generated by the predict-then-optimize approach, assuming the machine learning model will make predictions at a predetermined prediction performance level. Instead of training and testing machine learning models, our methodology simulates the predictions based on a characterization of model performance. We show how this methodology can be applied to identify the minimum performance level needed for the model to outperform simple non-data-driven robust rostering policies. In a computational study on a nurse rostering problem, we demonstrate how the predict-then-optimize approach outperforms non-data-driven policies under reasonable performance requirements, particularly when employees possess interchangeable skills.


Ten red flags signaling your analytics program will fail

#artificialintelligence

One or more of these issues is likely what's holding your organization back. How confident are you that your analytics initiative is delivering the value it's supposed to? These days, it's the rare CEO who doesn't know that businesses must become analytics-driven. Many business leaders have, to their credit, been charging ahead with bold investments in analytics resources and artificial intelligence (AI). Many CEOs have dedicated a lot of their own time to implementing analytics programs, appointed chief analytics officers (CAOs) or chief data officers (CDOs), and hired all sorts of data specialists. However, too many executives have assumed that because they've made such big moves, the main challenges to becoming analytics-driven are behind them.

Hard at work: A review of the Laevo Exoskeleton

Robohub

Back pain is one of the leading causes of work absenteeism in the UK, with 8.8 million days lost to work-related muscoskeletal disorders per year. On average, each case causes 16 days of absenteeism, and chronic conditions can cause some absences to become permanent. But working in a bent forward, back straining posture is unavoidable in a great many professions, like in hospital, agricultural and warehouses environments to name but a few. This regular exposure to demanding postures increases the risk of debilitating pain, which can severely reduce productivity and moral in the workforce. The Laevo Exoskeleton aims to alleviate this problem.


Glove puppet?

BBC News

What one piece of technology would most improve your working life? Chances are it wouldn't be a glove. But car workers in Germany are now using smart gloves that not only save time but prevent accidents as well. It is an example of how tech-enhanced humans are fighting back against the seemingly unstoppable rise of the robots. At BMW's spare parts plant in Dingolfing, for example, which employs around 17,500 people, hand-held barcode readers have been replaced by gloves that scan objects when you put your thumb and forefinger together.
