New Localizable Entanglement
In this study, we have addressed an ambiguity in the concept of localizable entanglement (LE) introduced by Verstraete et al in 2004. By doing so, we have proposed and explored a unique form of this entanglement, called new localizable entanglement (NLE). We have shown that NLE is always less than or equal to LE. Additionally, we have demonstrated that for systems with three components, NLE does not differ significantly from LE. However, when the number of components increases to four, there is…

Versatile and Generalizable Manipulation via Goal-Conditioned Reinforcement Learning with Grounded Object Detection
General-purpose robotic manipulation, including reach and grasp, is essential for deployment into households and workspaces involving diverse and evolving tasks. Recent advances propose using large pre-trained models, such as Large Language Models and object detectors, to boost robotic perception in reinforcement learning. These models, trained on large datasets via self-supervised learning, can process text prompts and identify diverse objects in scenes, an invaluable skill in RL where learnin…

Versatile and Fast Location-Based Private Information Retrieval with Fully Homomorphic Encryption over the Torus
Location-based services often require users to share sensitive locational data, raising privacy concerns due to potential misuse or exploitation by untrusted servers. In response, we present VeLoPIR, a versatile location-based private information retrieval (PIR) system designed to preserve user privacy while enabling efficient and scalable query processing. VeLoPIR introduces three operational modes-interval validation, coordinate validation, and identifier matching-that support a broad range o…

Ising versus infinite randomness criticality in arrays of Rydberg atoms trapped with non-perfect tweezers
Chains of Rydberg atoms have emerged as an amazing platform for simulating quantum physics in low dimensions. This remarkable success is due to the versatility of lattice geometries achieved by trapping neutral atoms with optical tweezers. On a given lattice, the competition between the repulsive van der Waals potential and the detuning of the laser frequency brings the atoms to highly excited Rydberg states, leading to a variety of exotic phases and quantum phase transitions. Experiments on th…

mimic-one: a Scalable Model Recipe for General Purpose Robot Dexterity
We present a diffusion-based model recipe for real-world control of a highly dexterous humanoid robotic hand, designed for sample-efficient learning and smooth fine-motor action inference. Our system features a newly designed 16-DoF tendon-driven hand, equipped with wide angle wrist cameras and mounted on a Franka Emika Panda arm. We develop a versatile teleoperation pipeline and data collection protocol using both glove-based and VR interfaces, enabling high-quality data collection across dive…

Julia Doubleday on the gamble that covid would be harmless to children
"It’s worth noting that at the time Kulldorff and the rest of the GBD crew were proclaiming COVID’s harmlessness to kids, they couldn’t possibly have had enough information to determine the veracity of their own claims. Viruses like the chickenpox, EBV, HIV, HPV, and HSV often present with mild initial infections but may cause major damage years later. We now know COVID can as well.
"For so-called experts to run with an assumption that an initially mild-presenting acute infection would be long-term harmless was just that; an assumption. They were willing to gamble the health of a generation of children on a guess in order to go “back to normal” because that’s what the oligarchy clamored for. Because it costs money to shut the world economy down. Because people who mattered were angry. Because children aren’t people who matter."
(GBD = Great Barrington Declaration, a bit of 2020 propaganda including the unfounded supposition that everyone who caught covid would be immune forever after)
Overall another excellent pointy article!

Tree-Structured Parzen Estimator Can Solve Black-Box Combinatorial Optimization More Efficiently

Abstract: Tree-structured Parzen estimator (TPE) is a versatile hyperparameter optimization (HPO) method supported by popular HPO tools. Since these HPO tools have been developed in line with the trend of deep learning (DL), the problem setups often used in the DL domain have been discussed for TPE such as multi-objective optimization and multi-fidelity optimization. However, the practical applications of HPO are not limited to DL, and black-box combinatorial optimization is actively utilized in some domains, e.g., chemistry and biology. As combinatorial optimization has been an untouched, yet very important, topic in TPE, we propose an efficient combinatorial optimization algorithm for TPE. In this paper, we first generalize the categorical kernel with the numerical kernel in TPE, enabling us to introduce a distance structure to the categorical kernel. Then we discuss modifications for the newly developed kernel to handle a large combinatorial search space. These modifications reduce the time complexity of the kernel calculation with respect to the size of a combinatorial search space. In the experiments using synthetic problems, we verified that our proposed method identifies better solutions with fewer evaluations than the original TPE. Our algorithm is available in Optuna, an open-source framework for HPO.

A Versatile Dataset of Mouse and Eye Movements on Search Engine Results Pages
We contribute a comprehensive dataset to study user attention and purchasing behavior on Search Engine Result Pages (SERPs). Previous work has relied on mouse movements as a low-cost large-scale behavioral proxy but also has relied on self-reported ground-truth labels, collected at post-task, which can be inaccurate and prone to biases. To address this limitation, we use an eye tracker to construct an objective ground-truth of continuous visual attention. Our dataset comprises 2,776 transaction…

Calamus 29 One flitting glimpse
What a sweet poem of quiet love. One of my favorites so far.
The setup is voyeuristic: we're spying on a bar full of men. And we see Whitman in a corner, and then
a youth who loves me, and whom I love, silently approaching, and seating himself near, that he may hold me by the hand
It astonishes me that these poems of clear homosexual love were published in 1860!
What's particularly nice is the contrast between the rowdy bar scene
drinking and oath and smutty jest
and the quiet intimacy of Whitman and his lover
we two, content, happy in being together, speaking little, perhaps not a word.
The expression of love here is universal. But it is a man writing about a man, in the company of men. And thus it is particularly mine.
