arXiv:2601.01594v2 Announce Type: replace Abstract: We study variance reduction for score estimation and diffusion-based sampling in settings where the clean (target) score is available or can be approximated. Starting from the Target Score Identity (TSI), which expresses the noisy marginal score as a conditional expectation of the target score under the forward diffusion, we develop: (i) a plug-and-play nonparametric self-normalized importance sampling estimator compatible with standard reverse-time solvers, (ii) a variance-minimizing emph{state- and time-dependent} blending rule between Tweedie-type […]

To get a first hand understanding of the impact of AI on the software development lifecycle (SDLC), I decided to run an experiment. I wanted to try and write a reasonably complex system from scratch using AI. I didn’t want a “Hello World” or another “To Do” app; I wanted something realistic, something that could be used at scale like we’d build in the enterprise world. The result is Under The Hedge—a fun project blending my passion for […]

This is an overview of the LLM development process. This one-hour talk focuses on the essential three stages of developing an LLM: coding the architecture, implementing pretraining, and fine-tuning the LLM. Lastly, we also discuss the main ways LLMs are evaluated, along with the caveats of each method.

This paper addresses the challenges in traditional enterprise performance analysis, including complex multi-source data structures, ambiguous indicator correlations, and poor decision interpretability. It proposes an enterprise performance optimization decision model that integrates knowledge graphs with causal inference. The model constructs a multi-entity and multi-relation knowledge graph to semantically integrate heterogeneous information from financial, market, and operational dimensions, enabling high-level representation of structured relationships among enterprise features. It further incorporates causal structure learning and inference mechanisms to identify key […]

AI Regulation in Life Sciences: The EU AI Act is a key regulatory development focusing on a risk-based approach to AI governance, particularly in high-risk areas like healthcare. Switzerland, a prominent AI hub, faces the challenge of balancing innovation with international regulatory alignment. Managing AI Risks: The EY Trusted AI Framework helps organizations understand and mitigate AI risks across various dimensions, including performance, bias, resilience, explainability, and transparency. Integrating AI risk management with existing ERM programs is crucial. […]

arXiv:2601.02415v1 Announce Type: new Abstract: Multimodal sentiment analysis is a key technology in the fields of human-computer interaction and affective computing. Accurately recognizing human emotional states is crucial for facilitating smooth communication between humans and machines. Despite some progress in multimodal sentiment analysis research, numerous challenges remain. The first challenge is the limited and insufficiently rich features extracted from single modality data. Secondly, most studies focus only on the consistency of inter-modal feature information, neglecting the differences between […]

arXiv:2601.03273v1 Announce Type: new Abstract: As large language models (LLMs) become deeply embedded in daily life, the urgent need for safer moderation systems, distinguishing between naive from harmful requests while upholding appropriate censorship boundaries, has never been greater. While existing LLMs can detect harmful or unsafe content, they often struggle with nuanced cases such as implicit offensiveness, subtle gender and racial biases, and jailbreak prompts, due to the subjective and context-dependent nature of these issues. Furthermore, their heavy […]

We develop a Bayesian framework for supervised dimension reduction using a flexible nonparametric Bayesian mixture modeling approach. Our method retrieves the dimension reduction or d.r. subspace by utilizing a dependent Dirichlet process that allows for natural clustering for the data in terms of both the response and predictor variables. Formal probabilistic models with likelihoods and priors are given and efficient posterior sampling of the d.r. subspace can be obtained by a Gibbs sampler. As the posterior draws are […]

arXiv:2601.10630v1 Announce Type: new Abstract: Classification imbalance arises when one class is much rarer than the other. We frame this setting as transfer learning under label (prior) shift between an imbalanced source distribution induced by the observed data and a balanced target distribution under which performance is evaluated. Within this framework, we study a family of oversampling procedures that augment the training data by generating synthetic samples from an estimated minority-class distribution to roughly balance the classes, among […]
