In this study, we focus on addressing the security and privacy challenges associated with the Internet of Medical Things (IoMT) and associated data. IoMT involves the transmission of large volumes of real-time medical data from various small devices. To tackle these challenges, we propose a novel approach that combines the Lightweight Encryption Algorithm (LEA) with the Paillier encryption approach. This combination is aimed at improving energy consumption, encryption time, and memory usage. By employing LEA encryption, our approach ensures both confidentiality and data integrity during the transmission of medical data. Additionally, the Paillier encryption technique is leveraged to preserve privacy and facilitate secure data aggregation. Through extensive security analysis and experimental evaluations, we have found that our proposed method achieves average encryption and decryption speeds that are 30% faster and 8% less energy consumption compared to the ECC-AES and ElGamal algorithms.

Automated essay scoring is one of the key applications of natural language processing technology in the field of education. Currently, pre-trained language models for automated essay scoring systems have no significant advantage over classical models, and pre-trained language models are underutilized for this task. Moreover, in real-world scenarios, supervised models that lack annotated data often perform poorly. To address the issue that the pre-trained language models are not fully applied, we propose a novel prompt tuning model PTAES in this paper, andwe convert the essay scoring procedure into a cloze-style question, after which we design pairs of natural language pattern-verbalizer. Further, we propose a joint model that combines the prompt tuning based model and the pre-trained fine-tuning based model, attempting to address the issue of inadequately supervised models in low-resource situations. Experimental findings indicate that, in supervised, semi-supervised, and zero-shot scenarios, our model can achieve state-of-the-art results, and our method further increases the value of the pre-trained language model in automated essay scoring.

Accumulation of cells with unimpeded growth is the hallmark for the development of life challenging brain tumor disease. In pre-existing research Machine Learning analytical models are trained on domain specific dataset to achieve goals of an Artificial Intelligence based application in Computer Science for the said disease identification. An ongoing research in the field is presented in this paper where an experimental set of 7038 domain specific images are used to train a model. On experiments conducted on the dataset using six different Machine Learning algorithms the researchers are able to identify Glioma tumor, Meningioma tumors and Pituitary tumor with an accuracy of 96% using RESTNET 5.0 with Transfer Learning Model.

Most available convolutional dictionary learning (CDL) methods use a batch-learning strategy, which consists of alternating optimization of the dictionary and the sparse representations using a training dataset. The computational efficiency of CDL can be improved using an online-learning approach, where the dictionary is optimized incrementally following a sparse approximation of each training sample. However, the existing online CDL (OCDL) methods are still computationally costly when learning large dictionaries. In this paper, we propose an OCDL approach that incorporates decomposed sparse approximations instead of the training samples and substantially improves the computational costs of the existing CDL methods. The resulting optimization problem is addressed using the alternating direction method of multipliers (ADMM).

This paper presents flood detection using anomaly detection algorithms in real-time weather data. Nine different attributes are used to detect suspicious weather that can cause floods. The weather dataset was acquired from Kelantan, Malaysia. In this paper, the collected dataset will be sent from the chosen Internet of Things (IoT) pipeline to three different anomaly detection algorithms. These algorithms are multi-threaded autonomous anomaly detection (MAAD), robust random cut forest (RRCF), and outlier detection in feature-evolving data streams (xStream). Our evaluation demonstrates that the MAAD algorithm has a 68.5% precision score and a 0.01 false alarm rate, which is better than the RRCF and xStream for detecting floods.

In photovoltaic systems, extracting parameters from generated current-voltage data is critical for simulating, controlling, and optimizing their performance. While there are several strategies for accomplishing this task, but they all have limitations. This work provides an improved adaptive differential evolution approach for solar system parameter extraction. A crossover rate sorting mechanism is developed in this system that allocates different crossover rates to individuals based on their fitness, allowing better-performing individuals to have a greater impact on the following generation. A Pelican optimization strategy used to speed up convergence and balance exploration and exploitation. The performance of the proposed method is validated by extracting characteristics from several solar models, including single diode, double diode, and photovoltaic modules. As a result, the proposed method is a viable and efficient option for parameter extraction in photovoltaic models.

Human activity detection from sensor data has developed as a critical study subject with far-reaching implications in healthcare, sports, security, and beyond. This study proposes a unique way to reliably detect and categorise human actions using sensor data, leveraging sophisticated machine learning algorithms implemented with Python and the NumPy library. The combination of the Python programming language with the NumPy library provides rapid data manipulation and mathematical calculations, therefore permitting simplified implementation of the suggested technique. The source is made accessible to the scientific community, enabling openness, reproducibility, and continued development. Experimental findings using benchmark datasets indicate the usefulness of the proposed strategy, exhibiting great accuracy and resilience across varied human activities. The attained performance not only beats previous approaches but also illustrates the potential of the offered strategy in real-world applications.

Due to the countless number of data sources, an integration issue emerges, as the same data often have several representations. Therefore, this paper suggests a Natural Language processing (NLP) based approach for the so-called Semantic Interoperability Toolkit. It comprises two components - the Semantic Matchmaking solution and the Semantic Engine - allowing users to identify similarities between concepts and manage queries against them respectively, regardless of their original representations. The solution is at use on the AI4PublicPolicy's data Marketplace for supporting the exploitation of a wide range of data sets.
