arXiv:2602.05790v1 Announce Type: cross Abstract: Fast computation of a matrix product $W^top X$ is a workhorse of modern LLMs. To make their deployment more efficient, a popular approach is that of using a low-precision approximation $widehat W$ in place of true $W$ (“weight-only quantization”). Information theory demonstrates that an optimal algorithm for reducing precision of $W$ depends on the (second order) statistics of $X$ and requires a careful alignment of vector quantization codebook with PCA directions of $X$ […]

Hello! My friend and I developed 3 models for predicting a win in a Tetr.io match based on playstyle and gameplay. We used this dataset: https://www.kaggle.com/datasets/n3koasakura/tetr-io-top-players-replays, and we had 7 million rows to work with. Some interesting findings for someone who is about only a month into playing Tetr.io (i copypasted from my notebook): • ⁠The amount of garbage received in a match is the most dominant contributor to losing. Receiving a large amount of garbage tends to […]

Sakana AI’s Digital Red Queen proves that competitive self-play, not supervised learning, may be the real path to artificial general intelligence The Paradigm Shift Hiding in Plain Sight On January 8th, 2025, Sakana AI and Japan’s Ministry of Internal Affairs and Communications published research that fundamentally challenges our assumptions about how machine learning systems acquire capabilities. Their Digital Red Queen (DRQ) algorithm didn’t just achieve superhuman performance in Core War — a Turing-complete programming game from 1984. It demonstrated something far […]

Primary bottleneck for Enterprise AI is not the availability of tools or the identification of a tech stack, it is getting the data landscape in order. Success in 2026 is predicated on having total clarity of the underlying data infrastructure and establishing a foundation that is petabyte-scale, secure, and high-performing. Without a reliable data layer, AI initiatives remain experimental rather than transformational. Foundation (Scalable and Maintainable Data Acquisition) A useful litmus test for the engineering foundation is time […]

arXiv:2602.10588v1 Announce Type: cross Abstract: When a source-trained model $Q$ is replaced by a model $tilde{Q}$ trained on shifted data, its performance on the source domain can change unpredictably. To address this, we study the two-model risk change, $Delta R := R_P(tilde{Q}) – R_P(Q)$, under covariate shift. We introduce TRACE (Theoretical Risk Attribution under Covariate-shift Effects), a framework that decomposes $|Delta R|$ into an interpretable upper bound. This decomposition disentangles the risk change into four actionable factors: two […]

arXiv:2604.08592v1 Announce Type: new Abstract: Reservoir observers provide a data-driven approach to the inference of unmeasured variables from observed ones for nonlinear dynamical systems. While previous studies have demonstrated wide applicability, their performance may vary considerably with different input variables, even compromising reliability in the worst cases. To enhance the performance of inference, we integrate residual calibration and attention mechanism into the reservoir observer design. The residual calibration module leverages information from the estimation residuals to refine the […]

Introduction Disclaimer: This article is a cross post from Pytorch Medium Blog Post. One of the most exciting advancements, that has pushed the frontier of the Artificial Intelligence (AI) in recent years, is Deep Reinforcement Learning (DRL). DRL belongs to the family of machine learning algorithms. It assumes that intelligent machines can learn from their actions similar to the way humans learn from experience. Over the recent years we could witness some impressive real-world applications of DRL. The […]

arXiv:2603.26697v1 Announce Type: new Abstract: This paper introduces Galactic Bioware’s Life Support System, a semi-closed-circuit breathing apparatus designed for integration into a positive-pressure firefighting suit and governed by an AI control system. The breathing loop incorporates a soda lime CO2 scrubber, a silica gel dehumidifier, and pure O2 replenishment with finite consumables. One-way exhaust valves maintain positive pressure while creating a semi-closed system in which outward venting gradually depletes the gas inventory. Part I develops the physicochemical foundations […]
