Lossless Compression of Vector IDs Boosts Approximate Nearest Neighbor Search

Lossless Compression of Vector IDs Boosts Approximate Nearest Neighbor Search

Researchers introduce a lossless compression scheme for vector IDs to address the high storage cost of indexes in approximate nearest neighbor search. Leveraging the fact that the order of IDs is irrelevant in many index structures, and utilizing asymmetric numeral systems or wavelet trees, the method achieves up to 7x compression of vector IDs without impacting accuracy or search runtime. This translates to a 30% reduction in index size for billion-scale datasets. Furthermore, the approach can also losslessly compress quantized vector codes by exploiting sub-optimalities in the original quantization algorithm.

Bypassing Middleboxes Blocking MPTCP with eBPF

2025-07-18

The MPTCP protocol can be blocked by middleboxes (like NATs, firewalls) in certain network environments. This article introduces an eBPF-based TCP-in-UDP solution that cleverly bypasses these limitations by encapsulating TCP packets within UDP packets. This solution requires no extra data layers or VPNs, simply reordering the TCP header and using eBPF to efficiently handle checksums, ultimately solving challenges posed by network stack optimizations and hardware offloading. While some minor issues remain, such as the loss of the URG flag and MTU/MSS adjustments, this approach offers an effective way to improve MPTCP performance in complex network environments.

Prolog Planners from LLMs: A Surprisingly Effective Approach

2025-04-02

This paper explores using Large Language Models (LLMs) to generate Prolog planners, leveraging Prolog's combinatorial search capabilities. The authors argue that LLMs are better suited for translating natural language into Prolog than for planning directly. Their approach involves prompting an LLM to translate problem descriptions into Prolog code, which is then used by a Prolog engine to perform the planning. A detailed prompting guide is provided, focusing on generating state facts, action predicates, and check predicates. This approach bypasses limitations of LLMs in direct planning while utilizing Prolog's strengths in logical reasoning and combinatorial search. The method is shown to be effective on various toy planning problems.

Frequency Shifts Don't Imply Quantum Entanglement: The Tardigrade Case

A recent, unpublished manuscript claims to demonstrate quantum entanglement between a superconducting qubit and a tardigrade, sparking much media attention. However, the authors cite a frequency shift in the qubit as evidence, a claim challenged by physicists. This post uses a simple mass-spring system analogy to illustrate the commonplace nature of frequency shifts. Even in quantum systems, frequency is primarily determined by mass and springiness, not entanglement. The author argues the experiment lacks sufficient evidence for quantum entanglement, attributing the observed frequency shift to classical physics.

Frozen Solid: Minnesota Woman's Miraculous Survival

In 1980, 19-year-old Jean Hilliard was found frozen solid after a car accident near Lengby, Minnesota. She had walked for help in -20 degree weather, only to be discovered unconscious and completely frozen on a rancher's doorstep. Against all odds, she miraculously thawed and awoke at a nearby hospital. Doctors, using only heating pads and prayers, managed to revive her from a state they believed to be almost beyond recovery. While medical science offers some explanation for her survival due to slowed metabolism in hypothermia, the speed of her recovery remains astonishing. Today, Hilliard lives a normal life, the incident shaping her caution towards winter driving rather than altering the course of her life.

Differentiable Logic Cellular Automata: From Game of Life to Pattern Generation with Learned Recurrent Circuits

2025-03-07

This paper introduces DiffLogic CA, a novel neural cellular automata (NCA) architecture using a fully discrete cell state updated via a learned, recurrent binary circuit. Replacing neural network components with Deep Differentiable Logic Networks allows differentiable training of discrete logic gates. The success of applying differentiable logic gates to cellular automata is demonstrated by replicating Conway's Game of Life and generating patterns through learned discrete dynamics. This highlights the potential of integrating discrete logic within NCAs and proves differentiable logic gate networks can be effectively learned in recurrent architectures. While promising, training for complex shapes remains a challenge, suggesting future work on hierarchical architectures and specialized gates for improved state management.
