Attention-based Ensemble for Deep Metric Learning
An attention-based ensemble, which uses multiple attention masks so that each learner can attend to different parts of the object, which outperforms the state-of-the-art methods by a significant margin on image retrieval tasks.

This work employs evolutionary approaches, based on a genetic algorithm, that avoid the computational complexity that makes the problem NP-hard and develops a novel distributed framework that works also with networks with cycles.
Collaborative Learning in Engineering Students: Gender and Achievement
Background Collaboration is an ABET accreditation required component of the engineering curriculum. Research has shown that collaborative learning positively influences student achievement. The…

This work demonstrates how a genetic algorithm solves the problem of minimizing the resources used for network coding, subject to a throughput constraint, in a multicast scenario and compares two different genotype encodings, which tradeoff search space size with fitness landscape.

The results revealed that global mean yields of maize and soybean will stagnate with warming even when agronomic adjustments are considered, and this trend is consistent across socioeconomic assumptions.
Examining students' future time perspective: Pathways to knowledge building
The purpose of this study was to provide evidence for the internal structure of the domain-general and context-specific components of future time perspective (FTP) and to provide support for a…

The key idea is to adopt class signatures that keep track of feature embedding online with minor additional cost during training, and identify hard negative example candidates using the signatures and achieves the state-of-the-art performance on the several standard benchmark datasets.
Abnormal Object Detection by Canonical Scene-Based Contextual Model
A novel generative model is proposed that detects abnormal objects by meeting four proposed criteria of success, and this model generates normal as well as abnormal objects, each following their respective tendencies.

Comparing the similarities and differences in global yield gaps, trend patterns, growth rates and changes in year-to-year variability shows that estimates of yield gaps and variability changes are more uncertain than those of yield trend patterns and growth rates.
