quantify physical exertion in AR/VR interaction using natural body gestures

Lacking of indications of physical exertion in XR applications,brings potential physical injuries to the general XR users.

A metric to help XR designers understand the physical exertion needed for the applications and guide them improve the design to avoid physical fatigue/injuries.

AR/VR Applications

Evaluated in 12 participants by comparing the existing model with the object fatigue measurements like surface EMG, using ART ANOVA.

An existing shoulder fatigue model (Consumed Endurance,Aka, CE) shows high correlation with the self-report fatigue but hasn’t been evaluated by objective approaches yet.

The XR community will be regulated based on the standardised physical exertion levels needed in the applications. XR designers will improve their designs based on this information and the general users can better protect themselves in the future XR engagement.

An existing model: CE can indicate the spent physical effort based on the shoulder gestures.

Learning analytics research has begun to recognise the importance of understanding the student perspective towards the services that could be potentially offered; however, student engagement remains low. Furthermore, there has been no attempt to explore whether students can be segmented into different groups based on their expectations towards learning analytics services

The current exploratory work addresses this limitation by using the three-step approach to latent class analysis to understand whether student expectations of learning analytics services can clearly be segmented, using self report data obtained from a sample of students at an Open University in the Netherlands

How Does Financial Development Impact Economic Growth? To find evidence from real data.

Using the quantile linear regression model.

Empirically, economic growth responds positively to financial development when the level of financial development surpasses a threshold value.

Most previous studies predicted a linear relationship between finance and growth. However, few studies argued that financial development occurs endogenously as the economy reaches a critical threshold of economic development.

To examines the nonlinear relationship between financial development and economic growth using the threshold regression model.

Theoretical literature suggests that financial development can promote economic growth.

Several empirical studies highlighted that financial development affects economic growth through capital accumulation and technological innovations.

The modeling approach is based on endogenous growth theories and Followed aggregate production function.

Find optimal shortest collision free path of a set of agents while considering turning costs

Study the solution quality between considering/ignoring turning costs.

Model problem and developing algorithms to solve the problem.

Multi-Agent Path Finding (MAPF) iis the well-studied problem of planning paths for multiple agents so that they can travel from their predefined start locations to their goal locations without any collisions. This problem is relevant to MAPF while considering more realistic settings.

Experiments are from public MAPF benchmarks, the experiments settings follow a standard experimental settings in this domain. Comparison between solvers are from the existing state-of-the-art solvers and ours.

We first shows that, from all domains, direct planning with turn actions yields significantly improved solution quality compared to approaches that leave turning considerations to post-execution planning. We also shows that our solver in MAPF with turnings results in better runtime (around 1.5 - 2 times speed ups) and more instances solved.

Technological rule: To enhance the structure awareness of PLMs in NLP using several graph masking strategies to inject local and global awareness of the input structure.

PLMs are typically pre-trained on free text which introduces domain mismatch between pre-training and downstream G2T generation tasks.

We propose graph masking pre-training strategies that neither require supervision signals nor adjust the architecture of the underlying pre-trained encoder-decoder model.

Previous work indicates that the linearisation step used in PLMs ignores the structural information of the graph (Wang et al., 2021), while explicitly modelling structured data could also lead to catastrophic forgetting of distributional knowledge (Ribeiro et al., 2021).

We evaluate our methods on three datasets: WebNLG+2020, DART, EventNarrative. We use the evaluation metrics: BLEU, METEOR, TER, BERTScore.

Our empirical findings highlight that our self-supervised strategies significantly outperform a strong underlying T5 baseline and achieve two new SotA results on two of the datasets WebNLG+2020 (Zhou and Lampouras, 2020) and EventNarrative (Colas et al., 2021). Additionally, we show our pre-training strategies are very efficient in utilising data and have a great potential for low-resource setting.

adopting a new objective function and a weight correction step in each boosting round to maximise the predictive gain per added components.

With a limited size of components in the model, we need to examine if the new approach produces higher accuracy.

We use empirical risks to measure the accuracy of the model produced by different algorithms, including the proposed method in this research. We also proposed a method to compare the balance between accuracy and interpretability.

There have been a few approaches to produce interpretable machine learning models, but if they do not limit the size of the model, the produced models cannot be understand by users.
