STCANet is a spatio-temporal coupled attention deep network model for predicting ocean currents, which consists of a spatio- temporal module and an attention module , forming a complex nested/coupled system. Understanding and optimizing the STCANet model is challenging due to the complexity of the underlying modules influencing model predictions.In this work we present STCANetViz, a web- based visual analysis tool for understanding and optimizing STCANet models. We proposed an Inter-Module Interdependencies Computing Algorithm (IMDCA), which computes module specific interdependency metrics derived from module interactions to optimize the STCANet model. A modular inter-dependency graph is then designed for examining and analyzing the behavior of the model.The graph consists of a network layer visualization (for module-level exploration) and a heatmap-scatterplot (for module output analysis). We implement a scalable visualization technique incorporating cloud storage for dynamically extracting, seamlessly visualizing and analyzing the high-dimensional ensemble data generated by the STCANet model on ensemble force-directed diagrams (EFDs).

Frequency-domain analysis using the fast Fourier transform (FFT) has been a popular method for diagnosing broken rotor bar (BRB) faults in squirrel-cage induction motors (IM). However, FFT analysis is limited by sampling frequency and time acquisition constraints, making it less effective under time-varying conditions. This paper introduces a novel BRB fault detection method for nonstationary conditions, building on the recently developed Robust Local Mean Decomposition (RLMD) and Hilbert Transform (HT) techniques. Our proposed method demonstrates that it can accurately track the frequency and amplitude of the 2sf component (where s and f represent the fundamental stator current frequency and motor slip, respectively) under non-stationary conditions. The efficacy of this method is validated through simulations conducted in the Matlab environment. .

Optimizing the delivery of products from a central depot to multiple retail locations presents a multifaceted challenge, especially when considering factors such as minimizing costs while ensuring product availability for customers. Traditional approaches to this problem often rely on heuristic methods or mathematical optimization techniques. However, these approaches may struggle to adapt to dynamic real-world scenarios with complex, evolving conditions. This study pioneers the application of Proximal Policy Optimization (PPO), a state-of-the-art reinforcement learning algorithm, to the domain of product transportation and inventory management. By creating a custom simulation environment, “ProductTransportEnv,” we delve into the complexities of supply chain logistics, demonstrating the significant potential of reinforcement learning to transform operational efficiencies. The “ProductTransportEnv” mimics real-world logistics scenarios, allowing for a detailed exploration of transportation routes, inventory levels, and demand fluctuations, providing a rigorous testing ground for the PPO algorithm.

The Big Island is one of the few countries in the world that boasts a specific biological megadiversity in terms of flora and fauna. With its exceptional biological diversity, we were guided to focus our study on the leaves of Melicope madagascariensis, belonging to the Rutaceae family, an endemic species, to discover its medicinal properties. The Rue family (Rutaceae) includes more than 125 species across 09 genera in Madagascar, most of which are woody shrubs and trees. The flowers are generally showy and fragrant, and many species have attractive aromatic foliage. Extensive research into the biological activities of the essential oil from the leaves of this plant has been carried out in the rainforest of Madagascars east coast. The essential oil of Melicope madagascariensis has a very specific chemotype. Various GPC and TLC analyses were carried out. The majority of essential oils contain (Z)-β- ocimene (12.7%) and (E)-β-ocimene (25.7%) belonging to the monoterpene family. The synergy of these various bioactive molecules, namely α-pinene (8.56 %); methyl chavicol (6.25 %); trans-piperitol (7.42 %); (E)-β-caryophyllene (3.21 %), gives it several biological activities and an aromatic profile that is unusual for Madagascar. The synergy of its bioactive molecules helps to eliminate free radicals and fungal germs. However, analyses of its toxicity have produced some interesting results. Therefore, the notion of the duality of "efficacity and toxicity" needs to be taken into account, as all active substances are potentially toxic. This is why a more in-depth toxicity study was carried out, using various in vitro tests, namely larval activity and acute toxicity, to determine the lethal dose (LD50) performed on Swiss Musculus L mice. Given its biological properties, the use of the essential oil of Melicope madagascariensis leaves offers a vast opportunity for scientific exploration.

In the last decades, people have been consuming and combining more drugs than be- fore, increasing the number of Drug-Drug Interactions (DDIs). To predict unknown DDIs, recently, studies started incorporating Knowledge Graphs (KGs) since they are able to capture the rela- tionships among entities providing better drug representations than using a single drug property. In this paper, we propose an end-to-end framework that integrates several drug features from public drug repositories into a KG and embeds the nodes in the graph using various translation, factorisation and Neural Network (NN) based KG Embedding (KGE) methods. Ultimately, we use a Machine Learning (ML) algorithm that predicts unknown DDIs. Among the different translation and factorisation-based KGE models, we found that the best performing combination was the ComplEx embedding method with a Long Short-Term Memory (LSTM) network, which obtained an F 1-score of 95.19% on a dataset based on the DDIs found in DrugBank version 5.1.8. This score is 5.61% better than the state-of-the-art model DeepDDI. Additionally, we also developed a graph auto-encoder model that uses a Graph Neural Network (GNN), which achieved an F 1-score of 91.94%. Consequently, GNNs have demonstrated a stronger ability to mine the underlying se- mantics of the KG than the ComplEx model, and thus using higher dimension embeddings within the GNN can lead to state-of-the-art performance.

In this work, an advanced deep reinforcement learning architecture is used to train neural network agents playing atari games. Given only the raw game pixels, action space, and reward information, the system can train agents to play any Atari game. At first, this system uses advanced techniques like deep Q-networks and dueling Q-networks to train efficient agents, the same techniques used by DeepMind to train agents that beat human players in Atari games. As an extension, plastic neural networks are used as agents, and their feasibility is analyzed in this scenario. The plasticity implementation was based on backpropagation and the Hebbian update rule. Plastic neural networks have excellent features like lifelong learning after the initial training, which makes them highly suitable in adaptive learning environments. As a new analysis of plasticity in this context, this work might provide valuable insights and direction for future works.

Text-based comments play a crucial role in providing feedback for various industries. However, effectively filtering and categorizing this feedback based on custom context-specific criteria requires sophisticated language modeling techniques. While traditional approaches have shown effectiveness, they often require a substantial amount of data to compensate for their modeling deficiencies. In this work, we focus on highlighting the performance and limitations of prompt-free few-shot text classification using open-source pre-trained sentence transformers. On the one hand, our research includes a comprehensive study across different benchmark datasets, encompassing 9 dimensions such as sentiment analysis, topic modeling, grammatical acceptance, and emotion classification. On the other hand, we underline prompt-free few-shot classification limitations when the targeted criteria are complex. As an alternative approach, prompting an instruction-fine-tuned language model has demonstrated favorable outcomes, as proven by our application in the specific use case of “Identifying and extracting resolution results and actions from explanatory notes”, achieving an accuracy rate of 80%.

News recommendation schemes utilize features of the news itself and information about users to suggest and recommend relevant news items to the users towards the interest they have. However, the effectiveness of the existing news recommendation scheme is limited in the occurrence of new user cold start problems. Therefore, we designed a news recommender system using hybrid approaches to address new user cold start problems to ease and suggest more related news articles for new users. To achieve the objective mentioned above, user demographic data with a hybrid recommendation system that contains the scheme of both content-based and collaborative filtering approaches is proposed. To evaluate the effectiveness of the proposed model, an extensive experiment is conducted using a dataset of news articles with user rating value and user demographic data. The performance of the proposed model is done by two ways of experiment. So, the performance of the proposed model performs around 68.05% of Precision, 42.46% of Recall and 52.1% of the average F1 score for the experiment based on individual user similarity in the system. And also performs around 93.75% of precision, 40.25% of recall and 56.31% F1-score for the similarity of users based on the similarity of users within the same category which is better than the first experiment.
