MEG-XL: Data-Efficient Brain-to-Text via Long-Context Pre-Training

arXiv
Clinical brain-to-text interfaces are designed for paralysed patients who cannot provide extensive training recordings. Pre-training improves data-efficient generalisation by learning statistical priors across subjects, but these priors critically de... read more 

PixelGen: Pixel Diffusion Beats Latent Diffusion with Perceptual Loss

arXiv
Pixel diffusion generates images directly in pixel space in an end-to-end manner, avoiding the artifacts and bottlenecks introduced by VAEs in two-stage latent diffusion. However, it is challenging to optimize high-dimensional pixel manifolds that co... read more 

Multi-head automated segmentation by incorporating detection head into the contextual layer neural network

arXiv
Deep learning based auto segmentation is increasingly used in radiotherapy, but conventional models often produce anatomically implausible false positives, or hallucinations, in slices lacking target structures. We propose a gated multi-head Transfor... read more 

UniReason 1.0: A Unified Reasoning Framework for World Knowledge Aligned Image Generation and Editing

arXiv
Unified multimodal models often struggle with complex synthesis tasks that demand deep reasoning, and typically treat text-to-image generation and image editing as isolated capabilities rather than interconnected reasoning steps. To address this, we ... read more 

Trust Region Continual Learning as an Implicit Meta-Learner

arXiv
Continual learning aims to acquire tasks sequentially without catastrophic forgetting, yet standard strategies face a core tradeoff: regularization-based methods (e.g., EWC) can overconstrain updates when task optima are weakly overlapping, while rep... read more 

Misconception Diagnosis From Student-Tutor Dialogue: Generate, Retrieve, Rerank

arXiv
Timely and accurate identification of student misconceptions is key to improving learning outcomes and pre-empting the compounding of student errors. However, this task is highly dependent on the effort and intuition of the teacher. In this work, we ... read more 

Personalized Image Generation via Human-in-the-loop Bayesian Optimization

arXiv
Imagine Alice has a specific image $x^\ast$ in her mind, say, the view of the street in which she grew up during her childhood. To generate that exact image, she guides a generative model with multiple rounds of prompting and arrives at an image $x^{... read more 

Self-Supervised Learning from Structural Invariance

arXiv
Joint-embedding self-supervised learning (SSL), the key paradigm for unsupervised representation learning from visual data, learns from invariances between semantically-related data pairs. We study the one-to-many mapping problem in SSL, where each d... read more 

Unified Personalized Reward Model for Vision Generation

arXiv
Recent advancements in multimodal reward models (RMs) have significantly propelled the development of visual generation. Existing frameworks typically adopt Bradley-Terry-style preference modeling or leverage generative VLMs as judges, and subsequent... read more 

C-kNN-LSH: A Nearest-Neighbor Algorithm for Sequential Counterfactual Inference

arXiv
Estimating causal effects from longitudinal trajectories is central to understanding the progression of complex conditions and optimizing clinical decision-making, such as comorbidities and long COVID recovery. We introduce \emph{C-kNN--LSH}, a neare... read more
