Crosstalk and several forms of coherent noise are invisible when qubit or a gate is calibrated or benchmarked in isolation. These are unlocked during the execution of full quantum circuit applying entangling gates to several qubits simultaneously. Unitary crosstalk noise, such as unwanted ZZ coupling, limits the state fidelity during the execution of cross-resonance CNOT gates in the superconductor quantum computers. This work presents (1) method of tracing coherent errors by exploiting their sensitivity to the arrangement of CNOT gates in the circuit and (2) correction scheme that modifies original circuit by inserting carefully chosen compensating gates (single- or two-qubit) to possibly undo coherent errors. On two vastly different types of IBMQ processors offering quantum volume 8 upto 32, our experimental results show up to 25% reduction in the infidelity of [[7, 1, 3]] code |+i state (clifford circuits) and 5- to 15-qubit W-states (non-clifford circuits). Our experimental circuits aggressively deploy forced commutation of CNOT gates to obtain low noise state-preparation circuits. Encoded state initialized with fewer errors, marks an important step towards successful demonstration of fault-tolerant quantum computers. © 2023, CC BY.

In this paper we present a system for person identification using dorsal hand veins pattern images. A simple approach is developed based on scale-invariant feature transform (SIFT) method for image features extraction, fast approximate nearest neighbors algorithm (FLANN) for keypoints matching in a preselected region-of-interest (ROI), and subsequent utilization of dense layer neural network for accurate friend-or-foe predictions. The efficiency of the considered approach is evaluated using an open dataset, and confusion matrices are calculated. The obtained results confirm again that dorsal hand veins identification systems are particularly promising for high-security settings. The proposed approach is implemented in software for Orange pi single-board computers. © 2024 IEEE.

There are some problems in traditional paper defects classification, such as the poor generalization performance, less types of recognition, and insufficient recognition accuracy. The deep learning method provides a new scheme for paper defects classification. However, due to the small sample size of paper defect images set, the over fitting phenomenon is easy to appear in the training process. Aiming this problem, a transfer learning method based on convolutional neural network model is ***, freezing the first seven construction layers of VGG16 network which has been trained by ImageNet, and fine tune the rest convolution layers with the paper defect images set to complete the feature extraction;Secondly, the full connection layers for classification are improved to meet the needs of paper defects classification;Finally, transfer learning strategy is adopted in the training process to improve the efficiency. The experimental results demonstrate that the paper defects classification proposed in our approach can improve the efficiency and accuracy of paper defects recognition. The approach will beneficial for the web inspection process. © 2021 Korean Technical Assoc. of the Pulp and Paper Industry. All rights reserved.

Earth Observation (EO) offers valuable insights into urban environments, and integrating artificial intelligence (AI) amplifies these benefits but also brings potential risks. AI practitioners often face challenges in envisioning diverse uses and conducting thorough impact assessments of their technology, particularly for less-studied uses. To address this, we developed UrbanGen, a framework validated through studies with urban EO practitioners and compliance experts. Practitioners and experts found UrbanGen valuable both for broad thinking and reflection by listing realistic AI uses for EO (91% accuracy) and identifying under-researched uses (57% accuracy), and for in-depth thinking and decision-making by providing risk (93% accuracy) and benefit (80% accuracy) assessments. UrbanGen highlighted less-studied and upcoming uses, such as analyzing foot traffic in retail areas, monitoring environmental law compliance, and detecting crowd sizes at election rallies. While most EO uses support sustainable cities, such novel uses pose higher risks, particularly in terms of surveillance, power imbalances, and decision-making detached from on-the-ground realities. Drawing from these insights, we propose an impact assessment checklist to help the EO community maximize benefits and reduce risks from AI deployments.

Motion systems are a vital part of many industrial processes. However, meeting the increasingly stringent demands of these systems, especially concerning precision and throughput, requires novel control design methods that can go beyond the capabilities of traditional solutions. Traditional control methods often struggle with the complexity and position-dependent effects inherent in modern motion systems, leading to compromises in performance and a laborious task of controller design. This paper addresses these challenges by introducing a novel structured feedback control auto-tuning approach for multiple-input multiple-output (MIMO) motion systems. By leveraging frequency response function (FRF) estimates and the linear-parameter-varying (LPV) control framework, the proposed approach automates the controller design, while providing local stability and performance guarantees. Key innovations include norm-based magnitude optimization of the sensitivity functions, an automated stability check through a novel extended factorized Nyquist criterion, a modular structured MIMO LPV controller parameterization, and a controller discretization approach which preserves the continuous-time (CT) controller parameterization. The proposed approach is validated through experiments using a state-of-the-art moving-magnet planar actuator prototype.

Residual networks play a foremost role in the domain of tracking, specifically in the extraction of features. The residual networks are using a simple technique of skipping connections to overcome the problem of vanishing gradient. Also, it is using batch normalization after each layer of convolution to accelerate the training by reducing the dependency over the parameters. Though, we have tried to solve these issues by introducing ResNeXt and NF-ResNet one by one into the TransT tracker as feature extractors in the place of ResNet. Finally, we present a ResNeXt-based TransT tracker (named as TransT_NeXt) and NF-Net-based TransT tracker (named as TransT_NFNet). We have evaluated proposed trackers on three large-scale benchmark datasets and four small-scale benchmark datasets but unfortunately, our trackers haven’t performed well. At last, we have discussed about the future work on the basis of this study. © 2024, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.

Realizing Generalized Zero-Shot Learning (GZSL) based on large models is emerging as a prevailing trend. However, most existing methods merely regard large models as black boxes, solely leveraging the features output by the final layer while disregarding potential performance enhancements from other layers. Indeed, numerous researchers have visually depicted variations in the features learned across different layers of neural networks. Motivated by this observation, we propose a Vision Transformer (ViT)-based GZSL method named Depth-Aware Multi-Modal ViT (DAM2ViT), which exploits multi-level features of ViT. DAM2ViT incorporates a multi-modal interaction block to align semantic information of categories across multiple layers, thereby augmenting the model’s capacity to learn associations between visual and semantic spaces. Extensive experiments conducted on three benchmark datasets (i.e., CUB, SUN, AWA2) have showcased that DAM2ViT achieves competitive results compared to state-of-the-art methods. © 2024 IEEE.

In the domain of high reliability applications, Burn-In testing (BI) is always present since it is one of the prime countermeasures against the infant mortality phenomenon. Traditional static BI testing proves to be inefficient for modern circuit designs. As the devices’ feature size scales down and their structural and architectural complexity increases, so does the complexity and cost of the BI test. Different BI methods are employed by the industry where stimuli are also applied to the devices under test (DUTs) in order to effectively stress and stimulate all nets of the design. One known industry practice resorts to Design for Testability (DfT) infrastructures (e.g., scan) and is based on the application of test vectors at low frequency to excite the DUT as much as possible with the goal of switching each net of the design at least once. In this paper we consider the case where the layout of the circuit is known and propose two novel methods able to automatically produce functional stimuli to switch pairs of neighboring nodes (i.e., nodes that are placed within a specified distance in the DUT) in short periods of time. This solution has been shown to be able to trigger some latent defects in a circuit better than other methods. As a case study, we target functional units within a RISC-V processor (RI5CY). We show that the functional stimuli generated by the exact method described in the paper are able to achieve optimal results (i.e., the maximum functional switching of neighboring pairs), thus maximizing the chance that their at-speed application can activate weak points in the circuit.
