Show HN: Put this touch sensor on a robot and learn super precise tasks
38 by raunaqmb | 3 comments on Hacker News.
We just released a very excited touch sensor that finally simplifies touch sensing for robotics. Our most exciting result: Learned visuotactile policies for precise tasks like inserting USBs and credit card swiping, that work out-of-the-box when you replace skins! To the best of our knowledge, this has never been shown before with any existing tactile sensor. Why is this important? For the first time, you could now collect data and train models on one sensor and expect them to generalize to new copies of the sensor -- opening the door to the kind of large foundation models that have revolutionized vision and language reasoning. Would love to hear the community's questions, thoughts and comments!

Ask HN: What runs L4-related microkernels/hypervisors these days?
10 by AlexWandell | 1 comments on Hacker News.
I've been learning about the L4 microkernel, and am thinking about doing something related to it for a research project. I'm especially curious about more recent examples of specific devices that run L4 variants (seL4, PikeOS, OKL4, etc.). I already found a few that use seL4, but to take OKL4 as an example, most of the specific devices I could find are from more than a decade ago, and I'm trying to find things from at least the last 5 or 6 years. I'm even more curious to find devices that use a form of L4 as a hypervisor. Has anyone here worked on a device that used an L4-related kernel or hypervisor? I know one major area they're used in is defense and full of NDAs, but hopefully some of the other industries they're used in (medical devices, automotive, IoT) are a little less restrictive. Thanks in advance!

New top story on Hacker News: Show HN: GitOps Template for Kubernetes

Show HN: GitOps Template for Kubernetes
21 by pmig | 1 comments on Hacker News.
Hello HN, we’re Philip Louis from Glasskube ( https://ift.tt/GZPtzgE ). We are working on a package manager for Kubernetes to simplify the packaging of complex applications with multiple dependencies, ensuring they are installed and kept up-to-date across multiple Kubernetes clusters. Nowadays, it is best practice to use Git as a revision control system for your Kubernetes configurations. Update automation workflows like Renovate or Dependabot can create pull requests for new versions of Docker images and Helm charts, but ensuring these new package versions work is still a manual task. By using the central (or a private) Glasskube repository ( https://ift.tt/AThIqaF ) together with our Renovate integration ( https://ift.tt/KvoWH0V ), you can ensure that new package versions will run through our Minikube-based CI workflows before they get published—similar to how the Homebrew core tap works. We’ve just introduced readiness checks for manifest-based deployments and utilize the flux-helm-controller to wait for a Helm release to succeed. Dependencies are resolved by our package controller. These dependencies can either be cluster-scoped (installed in the recommended namespace, e.g., operators wird CRDs) or namespace-scoped components of a package (e.g., a database or Redis cache). In such cases, we will prefix resources with the dependent package name to ensure multiple packages can use the same dependencies without naming conflicts (we use Kustomize on a virtual filesystem for this). Glasskube packages can currently be Helm charts (from an OCI or Helm repository) or manifests, which are mostly built using Kustomize’s overlay approach. Since neither the overlay approach (using Kustomize) nor Helm’s limited templating functionality will help us and other Kubernetes users scale to more complex packages, we are considering creating a more programmatic approach to package creation, similar to Timoni. Currently, KCL is our frontrunner ( https://ift.tt/4oh2UDP ), as it already integrates well with the Kubernetes ecosystem. We would appreciate if you give our GitOps template a try. It also works work existing Kubernetes clusters if just want to use GitOps for some applications. Just make sure that the argocd and glasskube-system namespaces are not yet in use. See: https://ift.tt/2GwKX6e

New top story on Hacker News: Show HN: Infinity – Realistic AI characters that can speak

Show HN: Infinity – Realistic AI characters that can speak
35 by lcolucci | 30 comments on Hacker News.
Hey HN, this is Lina from Infinity AI ( https://infinity.ai/ ). My co-founders and I have trained our own foundation video model focused on people. As far as we know, this is the first time someone has trained a video diffusion transformer that’s driven by audio input. This is cool because it allows for expressive, realistic-looking characters that actually speak. Here’s a blog with a bunch of examples: https://ift.tt/vD6Hsig If you want to try it out, you can either (1) go to https://ift.tt/SxVXfRh , or (2) post a comment in this thread describing a character and we’ll generate a video for you and reply with a link. For example: “Mona Lisa saying ‘what the heck are you smiling at?’”: https://bit.ly/3z8l1TM “A 3D pixar-style gnome with a pointy red hat reciting the Declaration of Independence”: https://bit.ly/3XzpTdS “Elon Musk singing Fly Me To The Moon by Sinatra”: https://bit.ly/47jyC7C Our tool at Infinity allows creators to type out a script with what they want their characters to say (and eventually, what they want their characters to do) and get a video out. We’ve trained for about 11 GPU years (~$500k) so far and our model recently started getting good results, so we wanted to share it here. We are still actively training. We had trouble creating videos of good characters with existing AI tools. Generative AI video models (like Runway and Luma) don’t allow characters to speak. And talking avatar companies (like HeyGen and Synthesia) just do lip syncing on top of the previously recorded videos. This means you often get facial expressions and gestures that don’t make sense with the audio, resulting in the “uncanny” look you can’t quite put your finger on. See blog. When we started Infinity, our V1 model took the lip syncing approach. In addition to mismatched gestures, this method had many limitations, including a finite library of actors (we had to fine-tune a model for each one with existing video footage) and an inability to animate imaginary characters. To address these limitations in V2, we decided to train an end-to-end video diffusion transformer model that takes in a single image, audio, and other conditioning signals and outputs video. We believe this end-to-end approach is the best way to capture the full complexity and nuances of human motion and emotion. One drawback of our approach is that the model is slow despite using rectified flow (2-4x speed up) and a 3D VAE embedding layer (2-5x speed up). Here are a few things the model does surprisingly well on: (1) it can handle multiple languages, (2) it has learned some physics (e.g. it generates earrings that dangle properly and infers a matching pair on the other ear), (3) it can animate diverse types of images (paintings, sculptures, etc) despite not being trained on those, and (4) it can handle singing. See blog. Here are some failure modes of the model: (1) it cannot handle animals (only humanoid images), (2) it often inserts hands into the frame (very annoying and distracting), (3) it’s not robust on cartoons, and (4) it can distort people’s identities (noticeable on well-known figures). See blog. Try the model here: https://ift.tt/SxVXfRh We’d love to hear what you think!

New top story on Hacker News: Show HN: Graphiti – LLM-Powered Temporal Knowledge Graphs

Show HN: Graphiti – LLM-Powered Temporal Knowledge Graphs
17 by roseway4 | 2 comments on Hacker News.
Hey HN! We're Paul, Preston, and Daniel from Zep. We've just open-sourced Graphiti, a Python library for building temporal Knowledge Graphs using LLMs. Graphiti helps you create and query graphs that evolve over time. Knowledge Graphs have been explored extensively for information retrieval. What makes Graphiti unique is its ability to build a knowledge graph while handling changing relationships and maintaining historical context. At Zep, we build a memory layer for LLM applications. Developers use Zep to recall relevant user information from past conversations without including the entire chat history in a prompt. Accurate context is crucial for LLM applications. If an AI agent doesn't remember that you've changed jobs or confuses the chronology of events, its responses can be jarring or irrelevant, or worse, inaccurate. Before Graphiti, our approach to storing and retrieving user “memory” was, in effect, a specialized RAG pipeline. An LLM extracted “facts” from a user’s chat history. Semantic search, reranking, and other techniques then surfaced facts relevant to the current conversation back to a developer for inclusion in their prompt. We attempted to reconcile how new information may change our understanding of existing facts: Fact: “Kendra loves Adidas shoes” User message: “I’m so angry! My favorite Adidas shoes fell apart! Puma’s are my new favorite shoes!” Facts: - “Kendra used to love Adidas shoes but now prefers Puma.” - “Kendra’s Adidas shoes fell apart.” Unfortunately, this approach became problematic. Reconciling facts from increasingly complex conversations challenged even frontier LLMs such as gpt-4o. We saw incomplete facts, poor recall, and hallucinations. Our RAG search also failed at times to capture the nuanced relationships between facts, leading to irrelevant or contradictory information being retrieved. We tried fixing these issues with prompt optimization but saw diminishing returns on effort. We realized that a graph would help model a user’s complex world, potentially addressing these challenges. We were intrigued by Microsoft’s GraphRAG, which expanded on RAG text chunking with a graph to better model a document corpus. However, it didn't solve our core problem: GraphRAG is designed for static documents and doesn't natively handle temporality. So, we built Graphiti, which is designed from the ground up to handle constantly changing information, hybrid semantic and graph search, and scale: - Temporal Awareness: Tracks changes in facts and relationships over time. Graph edges include temporal metadata to record relationship lifecycles. - Episodic Processing: Ingests data as discrete episodes, maintaining data provenance and enabling incremental processing. - Hybrid Search: Semantic and BM25 full-text search, with the ability to rerank results by distance from a central node. - Scalable: Designed for large datasets, parallelizing LLM calls for batch processing while preserving event chronology. - Varied Sources: Ingests both unstructured text and structured data. Graphiti has significantly improved our ability to maintain accurate user context. It does a far better job of fact reconciliation over long, complex conversations. Node distance reranking, which places a user at the center of the graph, has also been a valuable tool. Quantitative data evaluation results may be a future ShowHN. Work is ongoing, including: 1. Improving support for faster and cheaper small language models. 2. Exploring fine-tuning to improve accuracy and reduce latency. 3. Adding new querying capabilities, including search over neighborhood (sub-graph) summaries. ## Getting Started Graphiti is open source and available on GitHub: https://ift.tt/pgTndrD . We'd love to hear your thoughts. Please also consider contributing!
