Show HN: Deterministic objective Bayesian inference for spatial models [pdf] https://bit.ly/3nOYyp5

Show HN: Deterministic objective Bayesian inference for spatial models [pdf] To give some context, objective Bayesian inference refers to Bayesian analysis (i.e. integrating over the parameter space) using a prior that is design to represent "minimal information" (see [1], [2], and [3] for an overview). Particularly in cases where a model's likelihood function is not strongly peaked about a point, objective Bayesian inference can give better results than methods based off of point estimates like Maximum Likelihood [4]. Reference priors provides a general approach to construct so-called noninformative priors that are suitable for Objective Bayesian analysis ([5], [6]). The approach takes a practical viewpoint of noninformative priors and looks to build priors that are both tractable and provide good performance on frequentist coverage simulations. See Section 2 for a description of how the process and frequentist simulations work and [7] for examples with some basic models (e.g. why 1/σ^2 is the noninformative prior for the variance of normally distributed data with known mean). [8] was the first to develop reference priors for Gaussian processes models, and [9] extended the work to handle Gaussian Processes with noise (or nugget effects). The project I'm working on provides software and algorithms to do deterministic inference using the prior from [9]. Typically, such inference has been done using MCMC sampling algorithms; but my belief is that deterministic algorithms can give results that are more consistent, less sensitive to parameter tweaking, and more efficient, at the expense of some engineering cost and loss of generality. For an example of how the algorithms work on a real-world data set of zinc measurements in a flood plain along the Meuse river [10], see https://bit.ly/41qZ3n2...

Show HN: Marketing software for solopreneurs who don't like marketing https://bit.ly/42q8THg

Show HN: Marketing software for solopreneurs who don't like marketing Hey folks, I made 2Quiet2Market for busy solopreneurs who are "too quiet to market" what they build. I've been building this since September 2022 because I am a software dev who likes to talk factually but doesn't enjoy to "pound the drum" and "toot the horn" to market my stuff. On the other hand, if I don't market my stuff, people won't know about it and won't buy it. Bummer. So what did I do to make life better for quiet or factual people like me who like to build stuff and want to make money with it? I made a web-based app that helps you create your own habit for marketing. When people have a habit, they are more likely to do what needs to be done (marketing in this case). The free plan of my SaaS contains these tools: * Positioning blackboard * Story Composer * Experiment Designer Positioning blackboards provide you with Lego-like building blocks to make your product look awesome and desirable. They clarify your marketing until you reach a story you want to tell that will make your customer buy. Story Composer helps you create those stories step-by-step, and Experiment Designer lets you plan which stories to tell on which marketing channels, with a recipe on how to execute each marketing experiment. Already with the Free plan, you can create your specific marketing playbook and turn it into a habit. The Free plan allows you to have 1 project with 2 blackboards, and an "invite" feature to have a friend look at your stuff. There are two paid plans as well: - the Pro plan offers unlimited projects and blackboards, as well as an integration with the Todoist.com task management system. It automatically turns experiments into to-dos to get them done. And: The Pro plan also allows you to edit other people's stuff if they invite you to do so. - the Advanced plan adds GPT to spice up the factual marketing copy from Story Composer, in order to make it more engaging for your audience. Have fun, please try it out, and tell me whether you can use it to market your own stuff to the world. It comes with interactive demos on its dashboard, and with comprehensive docs at https://bit.ly/3nXxh3P Cheers, Matthias https://bit.ly/3nXItxk May 10, 2023 at 05:40PM

Show HN: ChattySurvey – Super easy AI powered conversational surveys https://bit.ly/3VTr7hQ

Show HN: ChattySurvey – Super easy AI powered conversational surveys My name is Richard D'Lonesteen I'm the CTO of ChattySurvey. This is the 6th startup idea I'm working on in the last 12 months. In a way, it was born because of the pain of doing MOM tests and understanding how tricky it can be to create good surveys and conduct them without falling for the flattery trap. We are building perhaps the simplest to create surveys in the world(let me know if I'm wrong). Currently, you can get super powerful(NPS, CSAT, PMF etc..) surveys just by filling out 1 text field with the name of the subject. We are leveraging GPT to conduct the surveys and analyse them. And so far it's doing an unbelievable job, but don't take my word for it - check it out! We are looking for pilot users and problems that we can help to solve! Thank you! https://bit.ly/3VYBuRC May 10, 2023 at 01:25PM

Show HN: Build progressively enhanced reactive HTML apps using Go and Alpine.js https://bit.ly/3Md1fdn

Show HN: Build progressively enhanced reactive HTML apps using Go and Alpine.js Fir leverages Golang’s standard library html/template package and a bit of alpinejs to allow building reactive UIs. You start with plain old html and use alpinejs to enhance it to bring no-page-reload interactivity to web apps. The Fir toolkit is designed for Go developers with moderate html/css & js skills who want to progressively build reactive web apps without mastering complex web frameworks. It includes a Go library and an Alpine.js plugin. How it works ? On receiving user-interactions the fir server re-renders html templates and sends it over the wire where the fir client library selectively updates the changed areas. When a user event is received by a Fir route, an array of html templates are rendered on the server and returned as an array of DOM events to the browser. The DOM events are consumed by the alpinejs plugin and dispatched within the DOM where listeners attached to elements can use the event to update the DOM. See the demo and quickstart here: https://bit.ly/3LSknMq https://bit.ly/3LSknMq May 10, 2023 at 01:03AM

Show HN: Spiti – Private video library for high-performing teams https://bit.ly/3VLchtH

Show HN: Spiti – Private video library for high-performing teams Hi HN I’m Therese, one of the founders of Spiti. My co-founder, Sai, and I are thrilled to launch Spiti to the HN community! We’ve been working on a better way for teams to organize, access, share, and collaborate on internal videos. Recently, we built the ability to record, too. It is built specifically to enhance remote and hybrid teams’ access to internal knowledge and context lost in historical conversations. ------- *tl;dr backstory:* We’ve worked in start-ups and larger companies. In our previous stints, searching for stuff took up a lot of time. Tooling solved for better access and collaboration in most cases, except videos. Recorded meetings, webinars, product demos, explainer videos, customer conversations, etc. were always scattered around in various folders on the cloud, links in emails, and Slack. But those videos are important, and easy access would save the team and us at least a few hours every week. ---------- We designed and built Spiti Team Video Library to address these challenges head-on and provide teams with their own private video library or, as we describe it — an internal YouTube for your team. One of the things we crafted carefully is its intuitive interface, designed to ensure a delightful viewing experience for otherwise boring team videos. Spiti also integrates seamlessly with popular storage and collaboration tools — Zoom, Google Drive, and Slack— making it easy for teams to centralize their meeting recordings, onboarding, and customer conversations — no more hunting for a video lost in the cloud or links lost on Slack channels. *A few key capabilities:* - Native Screen Recorder (for MacOS) - Native integration with Zoom, Google Drive & Slack - Securely connect and collaborate with individuals or teams outside your organization through Spiti Connect - Organize videos into Playlists - Comments and keep the conversation going - Embed entire playlists in Notion, Coda, and webpages - Search in a video through auto transcriptions for every video *Interesting ways our customers use Spiti* - Adding clarity to bug reports - Product demo videos for your customers - Reviewing GitHub PRs faster - Employee onboarding made async and repeatable We'd love to talk to you and learn how Spiti can improve your remote team's productivity and provide feedback on what we have built so far. We understand that collaboration needs vary from team to team, and we're dedicated to tailoring our platform to meet those specific needs. We look forward to your comments! https://bit.ly/3nTgxux May 9, 2023 at 06:15PM

Show HN: LLM, a Rust Crate/CLI for CPU Inference of LLMs (LLaMA, GPT-NeoX, etc.) https://bit.ly/41gObYN

Show HN: LLM, a Rust Crate/CLI for CPU Inference of LLMs (LLaMA, GPT-NeoX, etc.) G'day, HN! I'm one of the maintainers of `llm`. I've been working alongside a trusty group of contributors to bring this project to life, and we're now at a point where we're ready to share it with the world. Large language models (LLMs) are taking the computing world by storm due to their emergent abilities that allow them to perform a wide variety of tasks, including translation, summarization, code generation, and even some degree of reasoning. However, the ecosystem around LLMs is still in its infancy, and it can be difficult to get started with these models. `llm` is a one-stop shop for running inference on large language models (of the kind that power ChatGPT and more); we provide a CLI and a Rust crate for running inference on these models, all entirely open-source. The crate can be embedded in your own projects, allowing you to easily integrate LLMs into your own applications. We hope that `llm` can help to alleviate some of the pain points that users face when working with LLMs. Our goal is to build a robust solution for inferencing on LLMs that users can rely on for their projects, so that we can provide a moment of peace in the chaos of the LLM ecosystem. At present, we are powered by `ggml` (similar to `llama.cpp`), but we intend to add additional backends in the near-future. This means that we currently only support CPU inference, but we have several ideas in mind for how to add GPU support, as well as other accelerators. We're looking for feedback on the project, and we'd love to hear from you! If you're interested in contributing, please reach out to us on our Discord ( https://bit.ly/3pqaluA ), or post an issue on our GitHub ( https://bit.ly/44CwzcO ). https://bit.ly/3ptF6io May 9, 2023 at 05:37PM
