MRI has revolutionized the analysis and remedy of disorder by using imparting precise and accurate images of soft tissue. This technology has been similarly superior by means of the improvement of 3-D MRI, which permits improved detection and characterization of tumors and improves accuracy of diagnosis and remedy. 3D MRI has been found to be in particular beneficial within the characterization of brain tumors as it offers a greater detailed assessment of tumor size, shape and composition, in comparison to traditional imaging techniques including X-ray or CT. This information can help in identifying the nature of the tumor that may impact its remedy and analysis. Furthermore, 3D MRI is useful for figuring out the chance of malignant invasion, which can provide important information for affected person control. Additionally, the advanced decision of 3-D MRI permits better delineation of areas of healthy and diseased tissue that can assist clinicians in making plans complex surgeries. (3-D) MRI has emerged as an increasingly more critical tool inside the characterization of brain tumors. The three-D imaging affords distinct anatomical visualization of the tumor and it's courting to surrounding systems, allowing for extra effective remedy making plans. Furthermore, the potential to visualize tumor tissue parameters together with edema, necrosis, and perfusion may be used to decide whether a tumor is malignant or no longer. 3D MRI has additionally enabled the evaluation of tumor vascularization, which serves as a vital prognostic indicator. The statistics received from 3-D imaging can then be used to be expecting the recurrence of a tumor following treatment, supporting to manual decisions on comply with-up remedies. The reduction in test time, decrease value, and better resolution of 3-D MRI in contrast to standard x-ray imaging also makes the technology more and more attractive for brain tumor management. © 2024 IEEE.

Memory bandwidth and power consumption is of utmost importance in the design of low power edge devices. This makes it essential to conserve power both at the sensor node and the computational unit. Our paper proposes a system design methodology to save power by acquiring compressed data at the CMOS Image Sensor (CIS) and making the Convolutional Neural Network (CNN) models lightweight for edge applications. A detailed study highlights the effect of sensor directed sparsity at the CIS, and its effect on CNN models such as VGG-16, MobileNet, ResNet50, EfficientNet, and ResNext models. It provides empirical evidence that the performance is mostly maintained even after pruning and quantization of considered models. The imagenette dataset is used to curate the data with the proposed acquisition pipeline that introduces data sparsity, and the experimental results provide evidence that the proposed pipeline performs at par with conventional CIS acquisition mode. For example, the analysis of VGG-16 model for a sparsity threshold level of 0.2 shows compression of × 7.6, × 16, and × 61 using only pruning (P), only quantization (Q), and with both pruning+quantization (P+Q), respectively. It is also observed that the proposed acquisition pipeline can achieve significant parameter reduction through pruning for model compression, comparable to convectional pipeline. © 2024 IEEE.

Previous research on fraud detection modeling is often based on a single algorithm, optimizing categories and clusters to find fraudulent patterns that they have provided unsupervised or supervised methods alone and within the framework of Hadoop. The proposed model, a model based on big data analysis extracts important features of user behavior patterns such as time, device type, values, and type of transaction, and their behavioral modeling. By creating different profiles for users, threshold values will be set for each of them. The proposed model for real-time fraud detection of electronic cash payment cards includes two fast and explicit filters. Fast filtering is the combination of the Hidden Markov Model of the first order and Self Organizing Maps (SOM) for fast transaction processing and the Baum-Welch algorithm to find the local Maximum Likelihood. Explicit filter model training is a combination of multilayer Perceptron Neural Network algorithms and Logistic Regression to create a cardholder profile and measure the amount of new transaction deviation from the created profile with the reduction mapping approach or parallel execution of the model. Also, transactions performed for aggregation filters and prediction of the output results of the Schaffer Demister function with the parameter θ in order to detect the degree of deviation of the transaction behavior from the normal state according to the profile of the customer and the maximum difference between two consecutive sequences of observations is used. Finally, the fraudulent or non-fraudulent label on the transaction will be applied and added to the relevant database for storage for later use. According to the model simulation results, the proposed Accuracy, Precision, Recall, and F1-Score criteria are 0.999, 0.9834, 0.7906, and 0.9214, respectively. Simulation results show that the proposed model will perform better in each of the compared criteria against each of the single algorithms. © 2023, The Author

Recognition of emotional state through the sound of the voice is a crucial element in human interactions. This process, known as emotional prosody, allows an individual’s emotions to be interpreted without the need to see his or her face or body language. The ability to identify emotions through voice is critical in areas such as psychology, health care, marketing and human-computer interaction technology. Moreover, in artificial intelligence systems and voice interfaces, the analysis of emotional prosody can improve the user experience and make interactions more personalized and intuitive. This study explores the robustness of a neural network in recognizing emotions within speech signals, considering the presence of environmental noise at different SNR levels. The study involves using public datasets containing different classes of emotions, training a CNN network to classify these emotional states, and then testing to evaluate the obtained performance. The results show that emotion recognition in speech is more accurate when the recording is clean and free of other noises. However, misclassification depends on the type of noise present and the type of emotion: indeed, it turns out that some emotions are more frequently misclassified than others. In fact, it is observed that accuracy is higher when using RAW data rather than MFCCs, with an accuracy of 75% compared to 60%. In addition, adding noise to the recordings results in a decrease in model performance. © 2023 Copyright for this paper by its authors.

Many central banks are researching and piloting digital versions of fiat money, specifically retail Central Bank Digital Currencies (CBDCs). Core to these systems' design is the ability to perform transactions even without network connectivity. Due to the lack of direct involvement of third parties in these offline transfers, various regulatory requirements that are key in the financial space need to be accommodated. This paper deploys a compliance-by-design approach to evaluate technologies that can balance privacy with anti-money laundering and counterterrorism financing (AML/CFT) measures. It classifies privacy design options and corresponding technical building blocks for offline CBDCs, along with their impact on AML/CFT measures, and outlines commonalities and differences between offline and online solutions. As such, it provides a conceptual framework for further techno-legal assessments and implementations. © 2024 IEEE.

Dual Operating Modes of In-Context Learning 41

Dual Operating Modes of In-Context Learning

41st International Conference on Machine Learning, ICML 2024

In-context learning (ICL) exhibits dual operating modes: task learning, i.e. acquiring a new skill from in-context samples, and task retrieval, i.e., locating and activating a relevant pretrained skill. Recent theoretical work proposes various mathematical models to analyze ICL, but they cannot fully explain the duality. In this work, we analyze a generalized probabilistic model for pretraining data, obtaining a quantitative understanding of the two operating modes of ICL. Leveraging our analysis, we provide the first explanation of an unexplained phenomenon observed with real-world large language models (LLMs). Under some settings, the ICL risk initially increases and then decreases with more in-context examples. Our analysis offers a plausible explanation for this "early ascent" phenomenon: a limited number of in-context samples may lead to the retrieval of an incorrect skill, thereby increasing the risk, which will eventually diminish as task learning takes effect with more in-context samples. We also analyze ICL with biased labels, e.g., zero-shot ICL, where in-context examples are assigned random labels, and predict the bounded efficacy of such approaches. We corroborate our analysis and predictions with extensive experiments with Transformers and LLMs. The code is available at: https://***/UW-Madison-Lee-Lab/Dual_Operating_Modes_of_ICL.

The COVID-19 pandemic has been scattering speedily around the world since 2019. Due to this pandemic, human life is becoming increasingly involutes and complex. Many people have died because of this virus. The lack of antiviral drugs is one of the reasons for the spreading of COVID-19 virus. This disease is spreading continuously and easily due to some common mistakes by people, like breathing, coughing and sneezing by infected persons. The main symptom is the normal flu. Therefore, in the present condition, the best precaution for this disease is the face mask, which covers both areas of mouth & nose. According to the government and the World Health Organization, everyone should wear a face mask in busy places like hospitals and marketplaces. In today's environment, it's difficult to tell if someone is wearing a mask or not, and physical inspection is impractical since it adds to labour costs. In this research, we present a mask detector that uses a machine learning facial categorization system to determine whether a person is wearing a mask or not, so that it may be connected to a CCTV system to verify that only persons wearing masks are allowed in. © 2021

Developing a real-time unsupervised anomaly detection system that is able to detect a broad range of attacks, including insider threats, distributed denial-of-service attacks, and Advanced Persistent Threats, among others, in real-time, is still a challenge. In this paper, a new anomaly detection scheme is proposed, which is based on the Activity and Event Network (AEN) framework, a new knowledge graph model that allows capturing the dynamicity and uncertainty inherent in network activities while providing a foundation for expressing various threat detection approaches. The considered unsupervised learning-based approach takes advantage of node clustering in the network to establish a normal behaviour for each cluster and detect the anomalies accordingly. Our proposed scheme is evaluated using the CIC 2018 IDS dataset, yielding a false positive rate (FPR) of 0.83% and a detection rate (DR) of 79%. © 2023 IEEE.

In the rapidly evolving domain of autonomous vehicles, ensuring safety and reliability through advanced anomaly detection is paramount. Reservoir Computing, a novel approach for processing time-series data in dynamic systems, stands out for its ability to capture complex temporal patterns efficiently. This paper introduces an innovative method that integrates Reservoir Computing with temporal-aware data analysis to enhance driver behavior assessment. Our approach employs a unique combination of autoencoder-based feature extraction and Reservoir Computing to analyze driving metrics from vehicle sensors. The autoencoder compresses and encodes these temporal features, which are then processed by a reservoir computing model, adept at processing intricate temporal dependencies in the data. To evaluate the effectiveness of our model we simulate with a GPS dataset of 10,000 taxis to identify various driving dynamics of speed, acceleration, and state changes providing a comprehensive view of driver behavior. We further categorize drivers into different sets based on their driving performance using a support vector machine (SVM) algorithm. Our algorithm marks a significant step forward in anomaly detection for autonomous vehicles, offering a route to safer driving experiences and advancing vehicle safety technologies. © 2024 IEEE.

Electricity consumption has been broadly concentrated on in the PC engineering field since numerous years. While the securing of energy as an action in ML is arising, a large portion of the trial and error is still essentially centered around getting raised degrees of precision with no computational limitations. We accept that one of the reasons for this deficiency of interest is because of their shortfall of straightforwardness with admittance to assess energy utilization. The principal objective of this study is come to assess valuable guidelines to the MLpeople group that grants them the major acknowledgment to utilize and fabricate energy assessment techniques for AI calculations. Utilization of various group models like Linear Regression, and random forest regression and gride search cv, adaboost algorithms to predict the power and to acquire exact outcomes. Notwithstanding, we additionally present the state-of-the-art programming apparatuses that award power assessment standards, along with two use cases that reinforce the request of energy fatigue in ML. Toward the end, we anticipate the future energy which is so useful to the matrix to make exact energy for the network by refreshing with shrewd meters where everyone can know individuals, who are involving more energy in what machines, so it is gigantically useful in which time we want more energy and less energy. © 2024, ICST Institute for computer sciences, Social Informatics and Telecommunications engineering.
