Ontology Driven Feature Engineering for Opinion Mining
IEEE Access, 2019 In the process of knowledge discovery, the reliability of results depends upon the effectiveness of attributes selected for decision. The curse of dimensionality refers to the phenomenon in which the excessive number of dimensions affect the analysis. In

Curse of dimensionality in neural network optimization
Information and Inference: A Journal of the IMAAbstract This paper demonstrates that when a shallow neural network with a Lipschitz continuous activation function is trained using either empirical or population risk to approximate a target function i.e. $r$ times continuously differentiable on $[0,1]^{d}$, the population risk may not decay at a rate faster than $t^{-\frac{4r}{d-2r}

Platform Thinking as a Catalyst for Circular Innovation in Low‐ and Medium‐Tech Industries
Business Strategy and the Environment, EarlyView.ABSTRACT Growing pressures to replace linear with circular models challenge organisations to innovate continuously and to absorb new knowledge. While platform thinking has been examined as an enabler of innovation in high‐tech industries, its relevance in low‐ and medium‐tech industries, like construction, remains underexplored.

Scalable Deep Multi-Agent Reinforcement Learning via Observation Embedding and Parameter Noise
IEEE Access, 2019 In this paper, we explore a scalable deep reinforcement learning (DRL) method for environments with multi-agents. Due to the explosive increase of the input dimensionality with the number of agents, most existing DRL methods are only able to cope with ...

Business Strategy and the Environment, EarlyView.ABSTRACT What propels a CFO in an emerging economy to champion ESG investments when formal regulations are weak? Moving beyond structural explanations, we provide a behavioural account arguing that a manager's internal ethical compass—moral intelligence (MI)—is a key driver.

Supervised Clustering of Persian Handwritten Images [PDF]
Journal of Sciences, Islamic Republic of IranClustering, a fundamental multivariate statistical method, serves as a valuable tool for extracting meaningful insights from complex datasets. Analyzing high-dimensional data, however, presents challenges, notably the curse of dimensionality.

Identification of novel genes regulating the development of the palate
Developmental Dynamics, EarlyView.Abstract Background The International Mouse Phenotyping Consortium (IMPC) has generated thousands of knockout mouse lines, many of which exhibit embryonic or perinatal lethality. Using micro‐computed tomography (micro‐CT), the IMPC has created and publicly released three‐dimensional image data sets of embryos from these lethal and subviable lines.

International Journal of Eating Disorders, EarlyView.ABSTRACT Objective Recovery from anorexia nervosa involves psychological and social adjustments that extend beyond weight restoration. Online forums increasingly serve as spaces where recovery experiences are openly shared, including accounts of “extreme hunger” during refeeding—a phenomenon that has not been reported in the clinical literature.

Graph Neural Network‐Based Prediction of Building Energy Consumption
Energy Science &Engineering, EarlyView.A graph neural network that encodes a multi‐zone building as a graph accurately predicts hourly cooling and heating loads across three distinct climates, outperforming Random Forest and XGBoost baselines and serving as a fast surrogate to EnergyPlus simulations for scalable building energy management.
