Antalia-2 Mini: A 7.6-million-parameter Turkish text-to-speech model trained entirely on synthetic speech

In briefAntalia-2 Mini: A 7.6M-parameter Turkish speech synthesis model trained only on synthetic audio

SummaryThis paper presents Antalia-2 Mini, a single-voice Turkish text-to-speech model with 7,620,931 parameters. All its training audio came from the teacher model VoxCPM2, and automatic checks kept about 1,790 hours. On the 495-sentence Freya-TR-Eval benchmark, version 1.0.1 reached a word error rate of 1.09% and a character error rate of 0.22%. A paired bootstrap cannot distinguish it from EMA Lightning, an 8.6M Turkish model.

FastWild-GS: Minutes-Scale In-the-Wild Gaussian Splatting via Compact Per-Image Appearance Adaptation

In briefFastWild-GS: Fast 3D scene reconstruction from varied internet photos using compact per-image appearance adaptation

SummaryThis paper presents FastWild-GS, a method for reconstructing 3D scenes from internet photos that differ in exposure, lighting, and transient objects. Each photo is described by a 128-dimensional appearance token and a six-parameter per-channel scale and offset, and a small MLP predicts Gaussian colours from these instead of spherical harmonics. On PhotoTourism it trains in 8.8 minutes per scene with the lowest LPIPS among compared methods, and on NeRF-OSR it achieves the best average PSNR, SSIM and LPIPS in 9.7 minutes per scene.

Relaxing Cross-Modal Correspondence for Multimodal Remote Sensing Pretraining

In briefRelaxing cross-modal pairing for multimodal remote sensing pretraining

SummaryThis paper examines whether multimodal remote sensing pretraining needs exact instance-level pairing across modalities. It proposes Semantic Pairing (SemPair), which pairs class-consistent samples from different instances instead, and uses a latent-factor model to argue that shared semantic structure is preserved. It also introduces Mixed Pairing (MixPair) to study pairing granularity along a spectrum. Experiments show SemPair matches exact pairing in transfer performance, while MixPair reveals a non-monotonic relationship with the instance-pairing ratio.

In briefAnchorMTS: Multi-View Forecasting for Long-Term Time Series

SummaryThis paper proposes AnchorMTS, which builds visual and textual views from each observed time-series window and uses them to refine a complete numerical forecast. A trainable path produces a candidate forecast, and a parameter-free projection bounds its deviation from the numerical anchor for each variable. Across six benchmarks and four horizons, it achieves the best macro MSE/MAE (0.336/0.367) among seven supervised baselines, and removing the auxiliary path raises macro MSE to 0.340.

LLM Validation Makes Minimal-Pair Benchmarks Easier for Language Models

In briefLLM validation of minimal-pair language tests makes them easier for the models tested

SummaryThe paper examines whether large language models can replace costly human judgments for validating minimal-pair benchmarks such as BLiMP (English) and QFrBLiMP (Quebec French). It finds that LLM-based filtering removes items that language models fail but humans do not, so the remaining items are easier for the models being tested. The authors release code, validator outputs and item-level scores.

WhyThe authors test LLM validation of minimal-pair benchmarks against human panels, reporting that filtering makes items easier for models across BLiMP, QFrBLiMP and BLiMP-NL.

The Target Is a Predicate: Predicate-State Grounding for Semantic-Level Video Reasoning Segmentation

In briefThe Target Is a Predicate: Predicate-State Grounding for Semantic-Level Video Reasoning Segmentation

SummaryThis paper introduces Predicate-State Video Reasoning Segmentation (PS-VRS), where a query defines a dynamic predicate over objects and time rather than a fixed object. The authors build PS-Bench, with 2,077 videos and 16,250 queries annotated with active/vacant states, temporal intervals, and pixel masks. They propose Predicate-State Grounding (PSG), a three-stage pipeline that predicts state tokens, aligns them to frames, and emits SAM2 masks only for active states. PSG outperforms baselines by 9.32 J&F on PS-Bench and significantly reduces false-positive mask emissions.

SummaryThis paper presents CP-GS, a framework for representing images with 2D Gaussians under a limited budget. It jointly optimizes how many Gaussians are used and how precisely their attributes are quantized, under a shared rate constraint. The Gaussian budget is reallocated from redundant regions to areas with higher representation demand, and quantization is distortion-aware. Experiments on DIV2K and Kodak report better rate-distortion performance than representative 2D Gaussian and implicit neural representation methods across a range of budgets.

It uses a photometric prior that the minimum pixel intensity across views of the same 3D point tends to reflect reflection-free content, and warps information from auxiliary views to build clean pseudo-labels for self-supervised optimization. An Adaptive Twin Rendering loss helps preserve high-frequency details from the original images.

SummaryThis paper examines whether a single RGB camera can replace depth sensors for mobile robot navigation. The authors find that off-the-shelf monocular depth models systematically overestimate the distance to nearby obstacles, causing frequent collisions in simulated indoor navigation. They propose a lightweight module on top of a frozen depth model that predicts a depth correction and uncertainty to produce a conservative "safe depth." In their experiments, collisions fall from 63% to 3% and navigation success rises from 37% to 70%.

Beyond Interaction Scores: Selecting Feature Interactions via Independent Replication

In briefSelecting Feature Interactions by Checking Whether They Replicate Across Independent Models

SummaryThis paper introduces LENS, a model-agnostic framework for selecting feature interactions. It trains two models with the same learning algorithm on disjoint data and accesses them only through predictions, removing main effects to measure each feature pair's interaction strength. It tests whether the second model reproduces the pattern at a meaningful strength, using a single multiple-testing correction and only two model fits. Experiments on synthetic designs, French motor insurance data, and two credit datasets show it retains few pairs while maintaining or slightly improving predictive performance.

WhyThe authors select feature interactions via independent replication, prove a strength floor restores selection consistency, and report results on synthetic and real data.

Exploring Synchrony for Communication in Modular Neural Networks

In briefSynchrony-based communication for modular neural networks

SummaryThe paper introduces SyncNet, a modular neural network that separates module content from a dynamical phase state. Learned Kuramoto dynamics evolve the phases, and phase alignment determines communication through a shared channel. Evaluated on Sort-of-CLEVR and SQOOP, SyncNet achieves the best held-out accuracy at the three lowest pair varieties, leading by 5.1 percentage points at the hardest setting. A content-addressed variant trained from scratch matches it, suggesting the gains stem from modular decomposition rather than synchrony itself.

In briefMixed Signals: Weight-Space Programming for EEG and ECG

SummaryThis paper explores using language models to read and edit the weights of neural networks, offering an alternative to gradient-descent training. The authors test the approach on EEG and ECG biosignal models, finding that frontier models can fix planted faults without being told what they are and can write network weights from scratch using only the architecture, task, and a few training subjects. In one experiment, a model matched standard training with six times fewer subjects and outperformed classic hand-crafted EEG pipelines built from the same five subjects. The authors note limitations, including difficulty improving already well-trained classifiers and unreliable identification of a network's task from its weights alone.

SummaryThis paper studies counterfactual editing of single cells, predicting how a cell would look if one factor were different. The authors show that the linear cross-covariance penalty used in prior concept bottleneck models fails to fully separate known and unknown factors when non-linear interactions exist. Adding a normalized Hilbert-Schmidt Independence Criterion (HSIC) recovers true intervention effects in simulations. Applied to a complex single-cell RNA-seq dataset, the non-linear model improves generation of counterfactual expression profiles across tissue environments.

Effects of Laser Beam Width and Measurement Noise on Tree Diameter Estimation in Laser Scanning

In briefLaser beam width and noise effects on tree diameter measurement by laser scanning

SummaryThis study examines errors from laser beam width and measurement noise in mobile laser scanning and how they affect stem diameter estimates. Simulations and experiments show that noise whose variance differs between range and scan angle, together with the lidar beam width, makes diameter bias depend on both distance and tree diameter. For trees with a diameter at breast height above 10 cm, the bias can be predicted and compensated using only sensor specifications, reducing stem diameter error to sub-centimeter level at boreal forest sites. For trees below 10 cm, bark and stem out-of-roundness limit accuracy.

SummaryThe paper presents tritify, an open-source runtime that runs model inference entirely in exact integer arithmetic, using floating point only for offline quantization and verification. The authors report bit-identical outputs across CPUs, instruction sets and CPU/GPU, decision agreement with a float reference, and identical results when computation is split across multiple machines. From this they argue that distributed inference can be verified by re-deriving the exact output bytes, though protection against a dishonest server is left to future work.

WhyThe authors run real models' forward passes in exact integer arithmetic, report bit-identical outputs across hardware and machines, and validate on several models including a 106B MoE.

Weighted-AoI-Driven UAV Trajectory and Reporting for Dynamic CKM Tracking

In briefWeighted-AoI-based UAV trajectory and reporting for tracking dynamic channel knowledge maps

SummaryExisting channel knowledge map construction assumes quasi-static environments and fails when channels decorrelate rapidly. The paper studies continuous online tracking of dynamic channel knowledge maps over a 2D airborne plane using a UAV fleet, formulating a long-term error minimization problem under UAV mobility and reporting constraints. It proposes a scheduling approach based on Weighted Age of Information (W-AoI), which combines temporal staleness with spatial uncertainty predicted by a 2D U-Net, and proves that top-K W-AoI selection maximizes a one-slot error reduction bound. Simulations show steady-state error reductions of 3.8 dB² and 4.8 dB² over AoI-only and FIFO baselines, closely approaching an idealized oracle.

TRUER: Test-Time Reward Correction Using an Error-Aware Rectifier for Reinforcement Learning

In briefTRUER: Fixing Test-Time Rewards with an Error-Aware Corrector for RL

SummaryThis paper introduces TRUER, a framework for test-time reinforcement learning in language models. Standard TTRL uses majority voting over the model's own answers as rewards, which can reinforce incorrect solutions, and the authors find that false positive rewards dominate reward errors. TRUER trains a reward rectifier with limited labeled data to separate correctness from consensus, emphasizing cases where incorrect majorities and correct minorities disagree. The rectifier is then frozen and used to correct rewards during test-time adaptation. The authors report that TRUER consistently outperforms naive TTRL in reward accuracy and model performance across all evaluated configurations.

CP-MLPs: A Tensor-Rank Theory of Tied and Untied MLP Blocks

In briefCP-MLPs: A Tensor-Rank Theory of Tied and Untied MLP Blocks

SummaryThis paper introduces CP-MLPs, a tensor framework that treats each multiplicative unit as a rank-1 interaction with detector, value, and output roles. It proves exact tensor-rank separations between tied gated blocks such as ReLU² and untied gated blocks such as ReGLU and SwiGLU, showing the width advantage of untying depends on the target structure. Experiments indicate that loss plateaus alone do not establish an approximation gap, since arbitrarily accurate approximation is governed by border rank.

WhyThe authors use CP tensor rank to show exact separations between tied and untied gated MLP blocks, with width advantages depending on target structure.

SummaryThis paper studies how tokenisers such as BPE shorten text by repeatedly merging adjacent symbol pairs. The authors prove that, unless P = NP, no polynomial-time algorithm can achieve an approximation within a factor of about n/log n, even for a single binary string. For merges that may skip occurrences, they give a simple algorithm achieving O(n/log log n). Over a one-letter alphabet, the related tokenisation problems are strongly NP-complete on datasets with repeated strings.

WhyThe authors reduce BPE-style merge selection to grammar size, proving approximation hardness on binary strings and strong NP-completeness for unary datasets.

The authors apply these to self-attention removal, which deletes the part of each attention head's output aligned with its own value vector. Across nine pretrained multi-head models, a causal earlier-position null accounts for 48% to 63% of this alignment.

EJAI: Judgment-Preserving Civic AI for Data Center Environmental Justice

In briefEJAI: A Civic AI System That Preserves Judgment on Data Center Environmental Justice

SummaryThis paper presents EJAI, a system that helps residents examine environmental justice issues raised by data centers. It combines an interactive map, retrieved evidence, statements about missing data, and two stakeholder personas so users can inspect the evidence and form their own policy recommendations. In a small functional benchmark, retrieved evidence supported 98.4% of factual claims. A within-subjects study with 15 participants preparing for a simulated town hall found that some users made conditional recommendations, while others judged the personas to be simplified or biased.

The RSI Tax: When Recursive Self-Improvement Is Not Worth the Cost

In briefThe RSI Tax: When Self-Improvement Costs Outweigh Gains

SummaryThis paper examines whether recursive self-improvement (RSI), where an AI agent improves itself using its own task experience, is worth its expense in continual task streams. It defines the "RSI Tax" as the token cost of the self-improvement process and evaluates it alongside task-execution costs. Across six methods and two language models, a bounded-note baseline matched or exceeded the accuracy of three RSI methods while saving 65.6-71.0% of total tokens. The authors find that verification makes up most of the tax, and that much of the associated cost goes to states or artifacts never used later.

Parallel Broyden Methods for Efficiently Evaluating Nonlinear State Space Models

In briefParallel Broyden methods for faster evaluation of nonlinear state space models

SummaryNonlinear state space models are usually evaluated one step at a time, which limits use of parallel hardware. This paper proposes a quasi-Newton method based on Broyden's method that approximates Jacobian blocks with diagonal-plus-low-rank terms built from trajectory secants, avoiding automatic differentiation and remaining compatible with parallel scan through rank compression. Experiments on low-rank RNNs, parallel MCMC algorithms, and denoising diffusion models show fewer iterations than other quasi-Newton methods, and it is the fastest parallel method when Jacobian evaluation is expensive or state dimensions are large.

Developing an Operational Model for an Internet of Data Based Trusted Data Space for Vocational Education

In briefOperational model for a trusted data space for vocational education

SummaryData sharing in vocational education has long been limited by unclear ownership, weak trust, and insufficient incentives. Building on an Internet of Data based trusted data space for vocational education, this paper develops a multi-stakeholder operational model. The model covers a value network, a product portfolio, revenue allocation, and governance rules. It emphasizes data sovereignty protection and incentive compatibility, offering a reference for sustainable regional vocational education data ecosystems.

Differentiable Filtering for Inertial Odometry

In briefDifferentiable Filtering for Inertial Odometry: a learning method that embeds Kalman filter updates into training to reduce drift in inertial positioning

SummaryInertial odometry is important for autonomous systems but suffers unbounded drift from integrated sensor noise and biases. The paper proposes DFIO, which embeds the update stages of an error-state Kalman filter into a computational graph and, after pre-training, jointly optimizes displacement and covariance outputs using posterior-position supervision through differentiable measurement updates. On a public pedestrian dataset, DFIO reduces mean absolute and one-second relative translation errors by 13.2% and 39.6% versus the TLIO baseline. Tests on noisy uncalibrated smartphone data indicate reduced translational drift and maintained trajectory alignment.

Seeing the Small: Deformable Duality Mamba for Retinal Lesion Segmentation

In briefDetecting Tiny Lesions: A Deformable Mamba Model for Retinal Segmentation

SummaryThis paper proposes D²Mamba, a model for segmenting diabetic retinopathy lesions that vary in shape and are often only a few pixels in size. It combines non-causal state space duality with deformable Mamba scanning to capture global context and adapt to lesion shapes. Evaluated with five-fold cross-validation on the DDR dataset, it achieved 33.87% mIoU, 2.99 points above the strongest baseline, with microaneurysm Dice improving by 10.06 points.

Evidential Deep Learning with conditional entropy for glaucoma detection

In briefGlaucoma detection with conditional-entropy evidential deep learning

SummaryThis paper proposes a conditional entropy function to quantify predictive uncertainty in Evidential Deep Learning for glaucoma detection from retinal fundus images. Validated on the EyePACS-AIROGS-light-V2 and RIM-ONE-DL datasets, the method produced uncertainty estimates with substantially lower calibration errors than Deep Ensembles, MC Dropout, post-hoc calibration, and conventional Dempster-based EDL. The authors also analyze Grad-CAM heatmaps with a focus index, finding that false negatives showed activations displaced from the optic disc.

Nepali-English Code-Mixed Speech Recognition: Data Preparation and Adaptation of a Speech Foundation Model

In briefNepali-English code-mixed speech recognition: data preparation and adapting a speech foundation model

SummaryThis paper adapts SraVaani, a 449M-parameter hybrid TDT-CTC speech model, to recognise speech that mixes Nepali and English, using a 172.8-hour corpus across six Nepali speech domains. Because the pretrained tokenizer lacks digits and several symbols, the authors generate Nepali and English readings for numbers and use zero-shot ASR output to choose a plausible form. Full fine-tuning lowers test word error rate from 48.6% to 17.1%, and a 12-epoch run reaches 16.3%, slightly better than fine-tuned Whisper large-v3-turbo at 16.4%.

TMAL: Topology-preserving Multi-offset Affinity Learning for Curvilinear Structure Segmentation

In briefTMAL: A method for segmenting thin, curved structures while preserving their connectivity

SummaryThis paper proposes TMAL, a method for segmenting thin, curved structures such as retinal vessels and surface cracks while keeping both pixel accuracy and structural continuity. It uses soft affinities that emphasize thin regions near boundaries and predicts directional affinities at several offsets, combined with weights from decoder features. The authors report that TMAL achieves the highest Dice, IoU, and clDice scores on the DRIVE and DeepCrack datasets and greatly reduces the connected-component error Δβ0.
