PINECONE’S $100M SERIES B

Pinecone seems to be one of the go to choices for vector databases. This is useful when you need a language model to interact with external data. You embed that data as a vector and store it in a database like this. One of the key reasons you’d do this is because of the context length problem - pinecone says this is “extending the long term memory of language models”. This certainly is exciting and many people use pinecone in production.

03RESEARCH & INNOVATION

LANGUAGE CONTROLLED MEMORY

SCM is a new system that allows LLMs to process long inputs. It is composed of three key modules: the language model agent, the memory stream, and the memory controller. SCM has been shown to be effective in processing long inputs, and it has the potential to be used for a variety of tasks.

SPARSEFORMER: SPARSE VISUAL RECOGNITION VIA LIMITED LATENT TOKENS

SparseFormer, a novel method inspired by human sparse visual recognition, represents images using a limited number of tokens in the latent space, achieving competitive performance with lower computational costs. This approach offers better accuracy-throughput tradeoffs and can be easily extended to video classification, potentially inspiring further research on sparse neural architectures.

LEARNING AGILE SOCCER SKILLS WITH REINFORCEMENT LEARNING

In this study, researchers use Deep Reinforcement Learning (Deep RL) to train a low-cost, miniature humanoid robot with 20 actuated joints to play a simplified 1v1 soccer game, resulting in the development of robust and dynamic movement skills and basic strategic understanding. The combination of high-frequency control, targeted dynamics randomization, and perturbations during simulation training enabled successful transfer to real robots, exhibiting improved performance and agility compared to a scripted baseline.

TEXTDEFORMER: GEOMETRY MANIPULATION USING TEXT GUIDANCE

The study introduces a technique for automatically deforming a triangle mesh based on a text prompt, leveraging differentiable rendering and pre-trained image encoders such as CLIP and DINO. By using Jacobians for mesh deformation representation, the method achieves smooth deformations and avoids noisy gradients, enabling large shape changes and fine details while maintaining coherence from all 3D viewpoints.

PHOTO-REALISM IN MULTI-VIEW IMAGE GENERATION

This research focuses on multi-view image generation for 3D-related applications such as image viewpoint editing. The proposed ray conditioning method generates multi-view images using a geometry-free approach, conditioning a 2D GAN on a light field prior, which offers improved photo-realism, identity consistency, and explicit viewpoint control while minimizing geometry artifacts and loss of fine-scale details.
