Wearable devices and smart sensors are increasingly adopted to monitor the behaviors of human artificial agents. Many applications rely on capability such recognize daily life activities performed by monitored users in order tailor their with respect occurring situations. Despite constant evolution sensing technologies numerous research this field, an accurate recognition in-the-wild situations still represents open challenge. This work proposes a novel approach for situation identification capable recognizing which they occur different environments behavioral contexts, processing data acquired wearable environmental sensors. An architecture situation-aware computing system is proposed, inspired Endsley's situation-awareness model, consisting two-step identification. The first identifies via learning-based technique. Simultaneously, context recognized using Context Space Theory. Finally, fusion between state allows identifying complex user acting. knowledge regarding forms basis smarter can be realized. has been evaluated ExtraSensory public dataset compared state-of-the-art techniques, achieving accuracy 96% significantly low computational time, demonstrating efficacy approach.

Federated Learning via Augmented Knowledge Distillation for Heterogenous Deep Human Activity Recognition Systems

Sensors, Год журнала: 2022, Номер 23(1), С. 6 - 6

Опубликована: Дек. 20, 2022

Deep learning-based Human Activity Recognition (HAR) systems received a lot of interest for health monitoring and activity tracking on wearable devices. The availability large representative datasets is often requirement training accurate deep learning models. To keep private data users' devices while utilizing them to train models huge datasets, Federated Learning (FL) was introduced as an inherently distributed paradigm. However, standard FL (FedAvg) lacks the capability heterogeneous model architectures. In this paper, we propose via Augmented Knowledge Distillation (FedAKD) FedAKD evaluated two HAR datasets: A waist-mounted tabular dataset wrist-mounted time-series dataset. more flexible than federated it enables collaborative with various capacities. considered experiments, communication overhead under 200X less compared methods that communicate models' gradients/weights. Relative other model-agnostic methods, results show boosts performance gains clients by up 20 percent. Furthermore, shown be relatively robust statistical scenarios.

Multi-Modal Hate Speech Recognition Through Machine Learning

Опубликована: Янв. 8, 2024

Because of the speedy surge in social media's expansion, proliferation malicious and harmful poses a substantial worry contemporary society. The identification hate speech on platforms like Twitter is crucial for various tasks such as controversial event extraction, AI chatterbot creation, content suggestions, sentiment analysis. Researchers have invested considerable effort addressing challenging task identifying hostile due to rise information. objective classify tweets Hateful, Offensive, or neither. However, this highly complex intricate nature natural language constructs, encompassing different manifestations animosity directed at demographics, multitude ways same meaning can be expressed.Previous research has predominantly relied manual feature extraction employed representation-learning techniques followed by linear classifiers. Nevertheless, deep learning methods recently demonstrated significant accuracy improvements problems across speech, vision, text applications. In study, This paper present an idea automatic classifications inappropriate expressions hostility using transfer models. research, leverage classified tweet datasets obtained from Kaggle conduct experiments.
