Manual screening of baggage at airports, shopping malls, and shipments to identify potentially dangerous items is a time-consuming process that requires the unwavering efforts of a human observer. Numerous researchers have addressed this issue by developing autonomous threat detection systems. However, the performance of these systems is still vulnerable to high occlusion and unbalanced contraband data. In this paper, we present a novel programmable CNN-driven broad learning system (BLS) that automatically adapts its design specifications to effectively recognize the concealed and imbalanced contraband data depicted within the baggage X-ray scans. First, the input scan is passed to the CNN backbone to extract distinct latent features. These features are then passed to the BLS model, which determines whether the scan contains potentially dangerous items or not. Additionally, the BLS's architecture (within the proposed framework) is programmed in such a way that no human effort is required to optimize it for producing the best threat detection performance. This novel design adaptation is performed via heuristics and greedy searches that quantify the importance of each edge fusing the adjacent node pairs to optimize the network's overall performance. The proposed system is thoroughly tested on three datasets, namely GDXray, SIXray, and COMPASS-XP, on which it leads the state-of-the-art by 2.94%, 19.33%, and 13.38%, respectively, in terms of F1 score. © 2022 IEEE.

Efficient learning of continuous-variable quantum states

The characterization of continuous-variable quantum states is crucial for applications in quantum communication, sensing, simulation, and computing. However, a full characterization of multimode quantum states requires a number of experiments that grows exponentially with the number of modes. Here we propose an alternative approach where the goal is not to reconstruct the full quantum state, but rather to estimate its characteristic function at a given set of points. For multimode states with reflection symmetry, we show that the characteristic function at M points can be estimated using only O(logM) copies of the state, independently of the number of modes. When the characteristic function is known to be positive, as in the case of squeezed vacuum states, the estimation is achieved by an experimentally friendly setup using only beamsplitters and homodyne measurements.

Combining Transformers with Natural Language Explanations

Many NLP applications require models to be interpretable. However, many successful neural architectures, including transformers, still lack effective interpretation methods. A possible solution could rely on building explanations from domain knowledge, which is often available as plain, natural language text. We thus propose an extension to transformer models that makes use of external memories to store natural language explanations and use them to explain classification outputs. We conduct an experimental evaluation on two domains, legal text analysis and argument mining, to show that our approach can produce relevant explanations while retaining or even improving classification performance. © 2023, The Authors.

Reasoning with constraints in database models

Integrity constraints are rules which should guarantee the integrity of a database. Provided that an adequate mechanism to express them is available, the following question arises: is there any way to populate a database which satisfies the constraints supplied by a designer? Constraints are expressed in various fashions, depending on the data model: in logic environment they are usually some subset of first order logic formulas, SQL2 allows general forms of inclusion dependencies and predicates to be evaluated on row values, while in OODBMSs most of the stuff is often left to the writing of methods. The contribution of the present work is twofold: first, to extend the expressiveness of complex object data models to capture the semantics of a relevant set of state constraints;second, to provide a specialized reasoner based on the tableaux calculus which is able to check the coherence of an object database schema with constraints. © 2023 CEUR-WS.

In modern organization theories, the social network established by cyber criminals is termed the crime cyber black industry chain. Under the current technical level, treating a crime cyber black industry chain as a whole dataset has to face severe challenges in many aspects, so the research of the sampling method specifically for it has been one of the current hot topics. Based on the structural feature of a cybercrime industry chain, the overall framework and the detailed algorithm of a multi-stage sampling method are proposed. Tested with real cybercrime datasets, our proposed multi-stage sampling method outperforms existing mainstream single-stage sampling methods at macro, meso, and micro scales, indicating it can solve practical problems with high efficiency and low cost. © 2024 IEEE.

Tight bounds on depth-2 QAC-circuits computing parity

We show that the parity of more than three non-target input bits cannot be computed by QAC-circuits of depth-2, not even uncleanly, regardless of the number of ancilla qubits. This result is incomparable with other recent lower bounds on constant-depth QAC-circuits by Rosenthal [ICTS 2021,arXiv:2008.07470] and uses different techniques which may be of independent interest: 1. We show that all members of a certain class of multivariate polynomials are irreducible. The proof applies a technique of Shpilka & Volkovich [STOC 2008]. 2. We give a tight-in-some-sense characterization of when a multiqubit CZ gate creates or removes entanglement from the state it is applied to. The current paper strengthens an earlier version of the paper [arXiv:2005.12169]. © 2025, CC BY.

Glaucoma is a progressive and degenerative optic neuropathy that damages the optic nerve due to increased intraocular pressure and yields various visual field abnormalities. Any damage to the optic nerve (due to glaucoma) is irreversible because of the incapacity of the retinal nerve fibers to regenerate. However, the glaucomatous progression can be properly cured if it is diagnosed in the early stages. Furthermore, health authorities worldwide have prioritized the early detection and prevention of glaucomatous progression, and in this regard, presenting a comprehensive insight on the recent literature serves as a critical benchmark to both researchers and clinicians. Towards this end, this paper presents a detailed overview of the state-of-the-art clinical and technical methods related to glaucomatous detection, grading, and prognosis. The clinical work focuses on glaucoma diagnosis and progression tracking in different retinal regions such as the retinal layers, optic never head, and lamina cribrosa, while the technical works focus on producing lesion-aware screening and grading of glaucomatous pathologies via optical coherence tomography. © 2022 IEEE.

Smart cities are considered data factories that generate an enormous amount of data from various sources. In fact data is the backbone of any smart services. Therefore, the strategic beneficial handling of this digital capital is crucial for cities. Some smart city pioneers have already written down their approach to data in the form of data strategies, but what should a city's data strategy include, and how can the goals and measures defined in the strategies be operationalized? This paper addresses these questions by looking closely at the data strategies of cities in Germany and the top three countries in the EU Digital Economy and Society Index. The in-depth analysis of 8 city data strategies has yielded 11 dimensions that cities should consider in their data strategy. These are (1) relevance of data, (2) principles, (3) methods, (4) data sharing, (5) technology, (6) data culture, (7) data ethics, (8) organizational structure, (9) data security and privacy, (10) collaborations, (11) data literacy. In addition, data governance is a concept to put these 11 strategic dimensions into practice through standardization measures, training programs, and defining roles and responsibilities by developing a data catalog. © ICT *** rights reserved.
