- Abstract summary: We consider a toy model for non-local quantum correlations in which nature resorts to some form of hidden signaling to generate correlations.
We show that if such a model also had memory, the parties would be able to exploit the hidden-signaling and use it to send a message.

- Abstract: We consider a toy model for non-local quantum correlations in which nature
resorts to some form of hidden signaling (i.e., signaling between boxes but not
available to the users) to generate correlations. We show that if such a model
also had memory, the parties would be able to exploit the hidden-signaling and
use it to send a message, achieving faster-than-light communication. Given that
memory is a resource easily available for any physical system, our results add
evidence against hidden signaling as the mechanism behind nature's non-local
behavior

We use Brain-Computer Interfacing technology to infer users' preferences, their attentional correlates towards visual content, and their associations with affective experience.
We link these to relevant applications, such as information retrieval, personalized steering of generative models, and crowdsourcing population estimates of affective experiences.

A novel arbitrary-in-arbitrary-out (AIAO) strategy makes watermarks resilient to fine-tuning-based removal.
Unlike the existing methods of designing a backdoor for the input/output space of diffusion models, in our method, we propose to embed the backdoor into the feature space of sampled subpaths.
Our empirical studies on the MS-COCO, AFHQ, LSUN, CUB-200, and DreamBooth datasets confirm the robustness of AIAO.

Building a predictive model that rapidly adapts to real-time condition monitoring (CM) signals is critical for engineering systems/units.
Current methods suffer from a trade-off between representation power and agility in online settings.
We propose a neural process-based approach that addresses this trade-off.

We exploit the properties of loophole-free nonlocal correlations to extend them over arbitrarily large distances.
We show that the higher the loophole-free nonlocality close to the source, the lower the threshold requirements away from the source.

We propose an iterative contrastive learning framework that requires no data annotations.
We then use the pseudo-labels to learn the correlation between the visual and audio signals sampled from the same video.
Our iterative strategy gradually encourages the localization of the sounding objects and reduces the correlation between the non-sounding regions and the reference audio.

Replay in neural networks involves training on sequential data with memorized samples, which counteracts forgetting of previous behavior caused by non-stationarity.
We present a method where these auxiliary samples are generated on the fly, given only the model that is being trained for the assessed objective.
Instead the implicit memory of learned samples within the assessed model itself is exploited.

Bell's theorem, stating that quantum predictions are incompatible with a local hidden variable description, is a cornerstone of quantum theory.
We propose to analyse a Bell scenario as a tensor network, a perspective permitting to test and quantify non-locality.
It allows to prove that non-signalling correlations can be described by hidden variable models governed by a quasi-probability.
