powerful computing efforts launched to boost research
Two major steps towards governmental oversight of artificial intelligence (AI) took place this week in the United States and the United Kingdom. Behind both initiatives are moves by each nation to boost their AI research capabilities, and includ efforts to broaden access to the powerful supercomputers needed to train AIs. On 30 October, US President…

A community partitioning algorithm for cyberspace
Cyberspace community structure Cyberspace is a virtual domain distinct from traditional geographic space, as it is an information network devoid of concepts of distance. Information within it spreads along specific paths and directions, with all kinds of events and processes occurring instantaneously and at zero distance. Hence, cyberspace is virtual, dynamic, directional, and open40. The…

Measuring skill via player dynamics in football dribbling
Model development Our starting point is the original one-dimensional Keller model37 for competitive running $$\begin{aligned} {\dot{v}}(t) = -\dfrac{1}{\tau }v(t) + f(t), \end{aligned}$$ (1) where v(t) is the runner velocity and the dot indicates a derivative with respect to time, f(t) is the positive force per unit mass exerted by the runner, assumed to be constant…

Hierarchical generative modelling for autonomous robots
Here we present the hardware implementation for inverting the implicit hierarchical generative model for autonomous robot control. The specification of the robot platform can be found in Supplementary Table 1. First, we detail the task that is completed autonomously by inverting the generative model, that is, using the model to predict sensor inputs and using…

Subjective data models in bioinformatics and how wet lab and computational biologists conceptualise data
Sample Based on the participant background survey, the majority of participants had postgraduate degrees in biology (doctoral or masters), but computational qualifications ranged from highschool/informal education only to full doctoral degrees. Years of full-time experience in biology ranged from one year to twenty-four years, with nearly half of participants (ten) having between ten to fifteen…

Doubly elastic net regularized online portfolio optimization with transaction costs
Price information We should consider price forecasting method to achieve the data-driven ideology, which can lessen the influence by irrational factors32,33,34 in the market. Specifically, we formulate the expected return by price forecasting method based on historical information. PAMR35 and CWMR12 showed that the predicted relative price in next period is inversely to the current…
