DeepSeek's mHC: Improving Residual Connections

Published:Jan 2, 2026 15:44
1 min read
r/LocalLLaMA

Analysis

The article highlights DeepSeek's innovation in addressing the limitations of the standard residual connection in deep learning models. By introducing Manifold-Constrained Hyper-Connections (mHC), DeepSeek tackles the instability issues associated with previous attempts to make residual connections more flexible. The core of their solution lies in constraining the learnable matrices to be double stochastic, ensuring signal stability and preventing gradient explosion. The results demonstrate significant improvements in stability and performance compared to baseline models.
Reference

“DeepSeek solved the instability by constraining the learnable matrices to be "Double Stochastic" (all elements ≧ 0, rows/cols sum to 1). Mathematically, this forces the operation to act as a weighted average (convex combination). It guarantees that signals are never amplified beyond control, regardless of network depth.”

ArXiv

Analysis

This paper investigates the properties of matter at the extremely high densities found in neutron star cores, using observational data from NICER and gravitational wave (GW) detections. The study focuses on data from PSR J0614-3329 and employs Bayesian inference to constrain the equation of state (EoS) of this matter. The findings suggest that observational constraints favor a smoother EoS, potentially delaying phase transitions and impacting the maximum mass of neutron stars. The paper highlights the importance of observational data in refining our understanding of matter under extreme conditions.

Stable LLM RL via Dynamic Vocabulary Pruning

Published:Dec 28, 2025 21:44
1 min read
ArXiv

Analysis

This paper addresses the instability in Reinforcement Learning (RL) for Large Language Models (LLMs) caused by the mismatch between training and inference probability distributions, particularly in the tail of the token probability distribution. The authors identify that low-probability tokens in the tail contribute significantly to this mismatch and destabilize gradient estimation. Their proposed solution, dynamic vocabulary pruning, offers a way to mitigate this issue by excluding the extreme tail of the vocabulary, leading to more stable training.
Reference

“The authors propose constraining the RL objective to a dynamically-pruned ``safe'' vocabulary that excludes the extreme tail.”

Constraining Lorentz Invariance Violation with Gamma-Ray Bursts

Published:Dec 28, 2025 10:54
1 min read
ArXiv

Analysis

This paper uses a hierarchical Bayesian inference approach to analyze spectral-lag measurements from 32 gamma-ray bursts (GRBs) to search for violations of Lorentz invariance (LIV). It addresses the limitations of previous studies by combining multiple GRB observations and accounting for systematic uncertainties in spectral-lag modeling. The study provides robust constraints on the quantum gravity energy scale and concludes that there is no significant evidence for LIV based on current GRB observations. The hierarchical approach offers a statistically rigorous framework for future LIV searches.
Reference

“The study derives robust limits of $E_{ m QG,1} \ge 4.37 imes 10^{16}$~GeV for linear LIV and $E_{ m QG,2} \ge 3.02 imes 10^{8}$~GeV for quadratic LIV.”

Analysis

This paper investigates the interaction between heavy dark matter (DM) and massive stars, focusing on how DM capture evolves throughout stellar evolution. It highlights the importance of accurate stellar modeling, considering factors like composition and halo location, to constrain heavy DM. The study uses simulations and the Eddington inversion method to improve the accuracy of DM velocity distribution modeling. The findings suggest that heavy DM could thermalize, reach equilibrium, or even collapse into a black hole within a star, potentially altering its lifespan.
