Abstract:

Feature selection is crucial to select an “optimized” subset of features from the original feature set based on a certain objective function. In general, feature selection removes redundant or irrelevant data while retaining classification accuracy. This paper proposes a feature selection algorithm that aims to minimize the area under the curve of detection error trade-off (DET) curve. Particle swarm optimization (PSO) is employed to search for the optimal feature subset. The proposed method is implemented in face recognition and iris recognition systems. The result shows that the proposed met

Abstract:

Cure models and receiver operating characteristic (ROC) curve estimation are two important issues in survival analysis and have received attention for many years. In the development of biostatistics, these two topics have been well discussed separately. However, a rare development in the estimation of the ROC curve has been made available based on survival data with the cure fraction. On the other hand, while a large body of estimation methods have been proposed, they rely on an implicit assumption that the variables are precisely measured. In applications, measurement errors are generally ubi

In this study, a falling weight impact test was conducted on EH690 steel specimens with V-notches using Digital Imaging Correlation (DIC). In conjunction with scanning electron microscopy (SEM), the plastic deformation and crack initiation processes were examined at the notch of the specimen under different impact energies (90 J, 120 J, 135 J and 150 J). ABAQUS was used to simulate the plastic deformation of an EH690 specimen. The results show that the strain at the notch tip experienced some elasticity and yielding as the load increased under different impact energies. The load remains unchan

This study examined how a suite of habitat and environmental variables relate to the ability of a stream surveyor to identify (observer efficiency) and distinguish (observer accuracy) steelhead (Oncorhynchus mykiss) redds from other stream features. Two existing spawning survey protocols that included one or two redd observers were used to develop models to estimate redd observer error. In most cases, steelhead redd abundances using raw redd counts were underestimated. Mean annual rates of observer efficiency ranged from 0.44 to 0.57, and observer accuracy ranged from 0.67 to 0.83.

The Receiver Operating Characteristic (ROC) curve is a crucial method for evaluating the effectiveness of diagnostic medical indicators and has found extensive applications. However, errors are inevitable in the data acquisition process. Therefore, discussions on error and various methods for improving and handling data have not only become the focus of academic discourse but also hold practical significance. Unlike general statistics, the diversity of error situations, ranges, and impacts in biostatistics often present unique challenges. In practical scenarios, such as drug experiments, limit

Abstract:

Accurate monitoring of cyclosporine (CsA) dosage is still a problem, because measurement of the area under the curve (AUC)--the most appropriate indicator of exposure to CsA--requires a number of blood samples to be taken over 12 h, which makes monitoring difficult in day-to-day clinical practice. This study investigated whether a limited sampling strategy in human kidney transplantation reflected the actual AUC better in patients given Neoral than in those being treated with Sandimmune. Stepwise multiple regression analysis of CsA blood levels recorded after Neoral administration to 20 renal

Abstract:

In the medical literature, there has been an increased interest in evaluating association between exposure and outcomes using nonrandomized observational studies. However, because assignments to exposure are not done randomly in observational studies, comparisons of outcomes between exposed and non-exposed subjects must account for the effect of confounders. Propensity score methods have been widely used to control for confounding, when estimating exposure effect. Previous studies have shown that conditioning on the propensity score results in biased estimation of odds ratio and hazard ratio.

However, it is impossible to measure all of gear pairs in mass production for actual transmission manufacturers. The prediction of transmission error by the simulation in high accuracy should be powerful and effectiv

Abstract:

Policymakers are often interested in the degree to which changes in prices are driven by shocks to supply or demand. One way to estimate the contributions of these shocks is with a structural vector autoregression identified using sign restrictions on the slopes of demand and supply curves. The appeal of this approach is that it relies on uncontroversial assumptions. However, sign restrictions only identify decompositions up to a set. I characterise the conditions under which these sets are informative, examining both historical decompositions (contributions to outcomes) and forecast error var

Abstract:

Among the most relevant applications of the definite integral in functions of a real variable are the computation of areas in non-regular flat regions and measuring distances along curved paths, which are widely employed in engineering and physics. These notes present the concept of definite integration, emphasizing its connection to calculating the area under a curve, as well as the arc length formula and its practical application for length measurement. Problem scenarios are introduced to illustrate the utility of these concepts, aiming to provide a solid understanding of the topics and thei

Abstract:

This work uses on-line monitoring of turbidity to ascertain the temperature impact on the mixing performance of kneading blocks with different geometries. For this purpose, one of the barrel segments of the extruder was modified to incorporate four sampling devices and a slit die containing optical windows. The experiments consisted in reaching steady extrusion and then adding a small amount of tracer. Upon opening each sampling device, material was laterally detoured from the local screw channel and its turbidity were measured by the optical detector. Residence time distribution (RTD) curves

Abstract:

Like most metering technologies, ultrasonic meters are known to be affected by the buildup of material inside the meter and surrounding pipe due to common pipeline contaminants. The buildup affects the metering accuracy by reducing the flow area sampled by the ultrasonic transducers and by changing the shape of the velocity profile through the creation of additional roughness elements on the pipe wall. The goal of this project was to relate the contamination level to the measurement error. The approach was to evaluate the flow measurement performance of two commercially-available ultrasonic fl

Abstract:

As an emerging field, the Internet of Vehicles (IoV) has a myriad of security vulnerabilities that must be addressed to protect system integrity. To stay ahead of novel attacks, cybersecurity professionals are developing new software and systems using machine learning techniques. Neural network architectures improve such systems, including Intrusion Detection System (IDSs), by implementing anomaly detection, which differentiates benign data packets from malicious ones. For an IDS to best predict anomalies, the model is trained on data that is typically pre-processed through normalization and f
