A robust p-Center problem under pressure to locate shelters in wildfire context

EURO Journal on Computational Optimization, 2020
The location of shelters in different areas threatened by wildfires is one of the possible ways to reduce fatalities in a context of an increasing number of catastrophic and severe wildfires.

Instability in deep learning – when algorithms cannot compute uncertainty quantifications for neural networks

European Journal of Applied Mathematics
In deep learning, interval neural networks are used to quantify the uncertainty of a pre-trained neural network. Suppose we are given a computational problem $P$ and a pre-trained neural network $\Phi _P$ that aims to solve $P$ .

The mathematics of adversarial attacks in AI – why deep learning is unstable despite the existence of stable neural networks

European Journal of Applied Mathematics
The unprecedented success of deep learning (DL) makes it unchallenged when it comes to classification problems. However, it is well established that the current DL methodology produces universally unstable neural networks (NNs).

A new distributionally robust reward-risk model for portfolio optimization

Open Mathematics
A new distributionally robust ratio optimization model is proposed under the known first and second moments of the uncertain distributions. In this article, both standard deviation (SD) and conditional value-at-risk (CVaR) are used to measure the risk ...

On the algorithmic solution of optimization problems subject to probabilistic/robust (probust) constraints [PDF]

, 2021
We present an adaptive grid refinement algorithm to solve probabilistic optimization problems with infinitely many random constraints. Using a bilevel approach, we iteratively aggregate inequalities that provide most information not in a geometric but in

A concept of copula robustness and its applications in quantitative risk management [PDF]

, 2022
In financial and actuarial applications, marginal risks and their dependence structure are often modelled separately. While it is sometimes reasonable to assume that the marginal distributions are ‘known’, it is usually quite involved to obtain ...

Shoes in Buddhist monasteries from India to China: From practical attire to symbol [PDF]

, 2016
One of the most visible identity markers of Buddhist monasticism is clothing. The robes of monks and nuns have been paid considerable attention by researchers. By contrast, other pieces of monas-tic clothing have attracted far less attention, and this is

A Field Study on the Effects of Norwegian Aquaculture Farms on the Intertidal Rocky Shore Community [PDF]

, 2021
The aquaculture industry has more than doubled since the early 2000s, and the growth is not predicted to stagnate any time soon. Norwegian salmonid aquaculture cages are usually open where waste is flushed from the cage by ocean currents, distributing ...
