Worried about Recursive Self-Improvement (RSI)? The answer might be CDE

A framework called CDE (Compositional Directed Evolution) avoids the uncontrollable risks of RSI (Recursive Self-Improvement) by keeping the model fixed and composing vetted tools. It uses static analysis to ensure safety, relocating defense from adversarial runtime to hardenable components while allowing capability growth.

AI technology is nearing a point where it could develop without human input

Anthropic co-founder Jack Clark warns that AI is approaching a tipping point where it could develop without human input, calling for a 'brake pedal' on AI development. He notes that Anthropic's Claude chatbot already writes 80% of its own code, and could reach 100% within two years. Clark draws parallels to oil industry regulation and urges society to discuss the implications of AI progress, including economic disruption and job displacement. He advises young people to cultivate creativity and liberal arts skills to thrive in an AI-driven economy.

Scientists are seriously asking if bees and ChatGPT are conscious

New studies suggest consciousness can't be judged solely by behavior, whether it's a chatbot discussing philosophy or a bee searching for nectar. Researchers are increasingly focusing on the internal mechanisms of brains and computers, concluding that today's AI is likely not conscious while leaving open the possibility for both conscious insects and future machines.

FlowPRO: Reward-Free Reinforced Fine-Tuning of Flow-Matching VLAs via Proximalized Preference Optimization

FlowPRO proposes a reward-free offline reinforced fine-tuning framework for flow-matching Vision-Language-Action (VLA) models. Its core algorithm RPRO combines a contrastive optimizer with an explicit proximal regularizer to eliminate reward hacking. Using a teleoperated intervention-and-rollback paradigm to collect paired trajectories, combined with smooth interpolation and batch mixing, it achieves dense per-state supervision. On four long-horizon bimanual tasks, FlowPRO achieves the highest success rate, outperforming four baselines.

Learning from Demonstrations over Riemannian Manifolds using Neural ODEs: An Extended Abstract

This paper proposes a novel method for learning from demonstrations (LfD) on Riemannian manifolds using neural ordinary differential equations (ODEs). While traditional LfD operates in Euclidean spaces, robot states like orientation naturally evolve on curved spaces. The method efficiently estimates geodesics via neural ODEs, enabling natural motion generation between arbitrary points on the manifold, and decodes the geodesics back to task space for robot deployment. Simulation experiments validate the framework's effectiveness.

MoDex: A Diffusion Policy for Sequential Multi-Object Dexterous Grasping

MoDex is a diffusion-based policy that enables a dexterous hand to sequentially grasp multiple objects without releasing those already held. By conditioning on opposition space and point cloud, it uses only a subset of finger degrees of freedom per grasp. Two-stage training (imitation learning + RL fine-tuning) improves success in simulation and real world.

LightVesselNet is an efficient neural network with only 75K parameters designed for retinal vessel segmentation in resource-constrained settings. It uses a compact encoder-decoder with channel and spatial attention, multi-scale feature aggregation at the bottleneck, subpixel upsampling, and edge residual connections. Experiments on five public datasets (DRIVE, STARE, CHASEDB1, FIVES, HRF) show competitive sensitivity (0.8096–0.8640) and Dice scores (0.7686–0.8649) while being more efficient than state-of-the-art models. Cross-dataset evaluation confirms generalization. It is a strong candidate for low-resource clinical deployment and mobile screening.
