Separating Behavioral Effect from Predictive Value in Dynamic Android Malware Detection: An Empirical Decomposition Study

This empirical study demonstrates that while fusing Strace and DroidBox runtime features significantly improves predictive performance in dynamic Android malware detection, behavioral richness and predictive utility remain distinct properties, as execution duration and sequence ordering effects do not consistently translate into better discrimination.

HyperCookies A hyperspectral dataset of cookies for spectral-spatial machine learning

This paper introduces HyperCookies, a publicly available hyperspectral imaging dataset of 160 cookies with varied cocoa contents and topping arrangements, designed to serve as a challenging benchmark for developing machine learning methods that effectively combine spectral and spatial information for classification.

An Optimized Approach for Handling Limited Vocabulary Constraints and Word Order Divergence in English-Urdu Neural Machine Translation

This study improves English–Urdu neural machine translation by compiling a large-scale parallel corpus and demonstrating that optimizing subword tokenization strategies (specifically Subword-NMT BPE and SentencePiece-BPE) combined with Dynamic Position Encoding effectively addresses vocabulary sparsity and word-order divergence to outperform baseline models.

The Complexity Landscape of Boolean Formula Isomorphism: From Graph Isomorphism to the Second Level

This paper precisely classifies the complexity of Boolean formula isomorphism within the polynomial hierarchy by establishing a bidirectional many-one equivalence between canonical formula isomorphism and graph isomorphism, while demonstrating that general formula isomorphism resides at the second level (Σ2P\Sigma_2^P) due to the combination of coNP-complete equivalence testing and the residual graph isomorphism core.

Incremental Value of Structured Metadata for Text Based Risk Triage in a Role Play Derived University Counselling Corpus

This study finds that adding structured metadata to text-based classifiers offers no consistent incremental benefit for university mental health risk triage, as message text alone outperforms structured-only models and combined approaches, though the role-play nature of the data and lack of autonomous-level performance necessitate further validation on authentic counselling records.

Multitask GRU Learning for Channel Disturbance Detection, Cause Classification, and QBER Forecasting in Simulated Decoy-State BB84

This paper presents a PyTorch-based multitask GRU model that successfully integrates channel disturbance detection, cause classification, and QBER forecasting for simulated decoy-state BB84 QKD links, achieving high accuracy in controlled environments while acknowledging limitations in generalizing to physical systems and unseen disturbance types.
