Accurate prediction of these reactions has become crucial within the clinical domain to guarantee prompt intervention. Many techniques have been presented to predict ADRs based on the drug’s molecular structure. However, these techniques are limited to the transformation of a multi-label classification problem into multiple binary problems and the formation of distinct classifiers for individual drug reactions. Such techniques can be computationally expensive and time-consuming when dealing with a large no. of ADRs. Moreover, the multi-label classifier can learn associations between multiple related ADRs more effectively. Therefore, the objective of this research is the multi-label classification of adverse drug reactions by incorporating transformers-based graph neural networks (GNNs). This paper presents a new model called GTransfNN (graph-based transformer neural network) that leverages graphs with transformers to analyze the molecular structure of drugs. It aims to predict 27 ADR categories based on the system organ class. The proposed model introduces three key characteristics as its main components: First, it considers an attention mechanism that operates on the interconnectivity among neighboring nodes within the graph. Second, it incorporates edge features together with node features while calculating the attention weight for each node. Finally, it replaces layer normalization with batch normalization. The results indicate that the proposed model outperforms the other state-of-the-art models, such as neural fingerprint and Attentive_FP model, with notable increases of 10% and 18% in AUC, respectively. It achieves an AUC of 0.82 and an accuracy of 0.83 on the SIDER dataset. Similarly, it showcases steady performance enhancements on the ADRECS dataset, attaining an accuracy of 0.84 and an AUC of 0.82 by showcasing a 5%, 16%, and 25% increase in AUC as compared to iADRGSE, BERT_Smile, and Attentive_FP methods. These results show the model’s robustness and reliability across different datasets, thereby contributing to more effective drug safety assessments and health-care decision-making processes.</p>","PeriodicalId":8109,"journal":{"name":"Arabian Journal for Science and Engineering","volume":"1 1","pages":""},"PeriodicalIF":2.9,"publicationDate":"2024-08-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141882503","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Conventional sentiment analysis methods often fail to effectively identify attitudes in Turkish texts, creating an urgent need for more efficient approaches. To fill this need, our study investigates the effectiveness of embedding techniques including pre-trained Turkish models such as Word2Vec, GloVe, and FastText in addition to two character-level embedding methods, namely, character-integer embedding (CIE) and character one-hot encoding embedding (COE), in conjunction with deep learning models specifically long short-term memory (LSTM), convolution neural networks (CNNs), bidirectional LSTM (Bi-LSTM), and hybrid models, for Turkish short-texts sentiment analysis. DL-based models were investigated on two datasets (e.g., an original Twitter (X) dataset and an accessible hotel reviews dataset). In addition to providing an intensive performance analysis of different embedding strategies and assessing their efficacy in dealing with the linguistic intricacies of Turkish, this study proposed a previously unexplored method in Turkish text representation that relies on a character-level one-hot encoding technique. The obtained findings indicate positive progress using a novel approach utilizing a dual-pathway architecture for both character level and word level that constitutes a substantial contribution to the area of natural language processing (NLP), specifically in the context of complex morphological languages. By employing a hybrid strategy that combines character and word levels on Twitter (X) data, the LSTM model obtained an <i>F</i>1 score of <span>(0.835 pm 0.005)</span> concerning cross-validation while CNN-BiLSTM attained the highest <i>F</i>1 Score (0.8392) using holdout validation.

Further research reveals that when the uneven temperature is coupled with these asymmetric factors, maintaining the influence value within 30 mm, and positioning the high-temperature side of the slab on the side opposing the tilt direction, while aligning the offsets of the slab and anvil in the same direction contributes to reducing the camber.

This study proposes a novel application of partial update Kalman filter (PUKF) where the PUKF profoundly enhances the accuracy of bilinear systems modelling. In the PUKF approach, only a subset of the parameter state vector is updated at each epoch, which could decrease the computational burden compared to the traditional Kalman filter. Moreover, this work uses a preaching optimisation algorithm (POA) to tune the PUKF parameters adaptively based on the estimation problem. The adequately adjusted adaptive PUKF provide good estimation results, stable filtering operation and quick convergence. A new objective function is formulated based on correlation functions and an error between the estimated and actual outputs. The new objective function significantly improved the quality of the solution. The sensitivity of POA on solution quality is analysed using various statistical parameters. The efficacy and correctness of the proposed algorithm are verified on a numerical plant and two real-time benchmark systems. The quantitative analysis based on the proposed scheme is examined with distinct standard metrics and robustness verified at different Gaussian noise variance levels. The accuracy, stability, and consistency of the proposed algorithm performance are verified through the Diebold–Mariano hypothesis test, results from several independent runs, and tenfold cross-validation tests.
