Open Source LLM development is going through great change through fully reproducing and open-sourcing DeepSeek-R1, including training data, scripts, etc. Hosted on Hugging Face’s platform, this ambitious project is designed to replicate and enhance the R1 pipeline. It emphasizes collaboration, transparency, and accessibility, enabling researchers and developers worldwide to build on DeepSeek-R1’s foundational work. What… →
Mixture-of-Experts (MoE) models utilize a router to allocate tokens to specific expert modules, activating only a subset of parameters, often leading to superior efficiency and performance compared to dense models. In these models, a large feed-forward network is divided into smaller expert networks, with the router—typically an MLP classifier—determining which expert processes each input. However,… →
Reinforcement learning (RL) focuses on enabling agents to learn optimal behaviors through reward-based training mechanisms. These methods have empowered systems to tackle increasingly complex tasks, from mastering games to addressing real-world problems. However, as the complexity of these tasks increases, so does the potential for agents to exploit reward systems in unintended ways, creating new… →
Generative modeling challenges in motion-controllable video generation present significant research hurdles. Current approaches in video generation struggle with precise motion control across diverse scenarios. The field uses three primary motion control techniques: local object motion control using bounding boxes or masks, global camera movement parameterization, and motion transfer from reference videos. Despite these approaches, researchers… →
CONCLUSIONS: Ivermectin and colchicine have no beneficial effect over standard care in the treatment of COVID-19. →
BACKGROUND: The Scottish Computed Tomography of the Heart (SCOT-HEART) trial demonstrated that management guided by coronary CT angiography (CCTA) improved the diagnosis, management, and outcome of patients with stable chest pain. We aimed to assess whether CCTA-guided care results in sustained long-term improvements in management and outcomes. →
CONCLUSIONS: Multiple sessions of HD-tDCS over the medial prefrontal cortex appears to have potential to produce meaningful cognitive enhancements in a proportion of patients having AD with improvements maintained for at least 8 weeks in some. →
BACKGROUND: No treatments exist for apathy in people with frontotemporal dementia. Previously, in a randomised double-blind, placebo-controlled, dose-finding study, intranasal oxytocin administration in people with frontotemporal dementia improved apathy ratings on the Neuropsychiatric Inventory over 1 week and, in a randomised, double-blind, placebo-controlled, crossover study, a single dose of 72 IU oxytocin increased blood-oxygen-level-dependent signal… →
Advancements in multimodal intelligence depend on processing and understanding images and videos. Images can reveal static scenes by providing information regarding details such as objects, text, and spatial relationships. However, this comes at the cost of being extremely challenging. Video comprehension involves tracking changes over time, among other operations, while ensuring consistency across frames, requiring… →
The artificial intelligence (AI) landscape is evolving rapidly, but this growth is accompanied by significant challenges. High costs of developing and deploying large-scale AI models and the difficulty of achieving reliable reasoning capabilities are central issues. Models like OpenAI’s GPT-4 and Anthropic’s Claude have pushed the boundaries of AI, but their resource-intensive architectures often make… →
