    Modeling: We are currently exploring this space so our findings are not final yet but let me share what we've found so far. TensorFlow.js is absolutely amazing, it provides a native port from TensorFlow to JavaScript with CPU, WebGL, WebAssembly and NodeJS backends. We were able to write an LSTM to do time series prediction, so far so good. However, we started hitting issues when we started to do simpler models, like a linear regression. We tried Regression.js but we found it falls short, so we wrote our own script to handle single-variable regressions using TF.js and gradient decent. It actually worked quite well but exposed a flaw in this approach; basically, there is a lot of work to be done to bring many models into the web. We also found out Arquero.js does not play nicely with TF.js since well, Arquero.js does not support tensors; so we went on to explore Danfo.js, which integrates great with TF.js but we found out it's hard to scale it's transformations to +1M rows and found other rough edges. Since then, well, we started exploring Pyodide and perhaps contributing to Danfo.js, or perhaps involve more server-side compute, but that will be a story for another time.

    At, we built components for data science com native JavaScript to avoid the waiting times and download overhead if Pyodide. We found out the best tools for doing data science in the browser are a combination of Arquero and D3 and TensorFlow.js. At least for now.

    We wrote our findings of this and many other libraries here:

    We are not using libfortran not gdpr, we are basically using whatever libraries are available for the web. Since most data scientists don't want to use JS per se, you can build the apps as blocks in the Hal9 site or using a soon-to-be-released Python/R package, see

    Feel free to check out our repo as well, all the "primitives" / blocks code is in the scripts folder:

  • Ask HN: Can you share websites that are pushing the utility of browsers forward?
    12 projects | | 15 May 2022 helps data scientists build faster web applications.

    It uses WebGL and WebAssembly to process larger datasets, perform inference in the browser with TensorFlow.js, and enables running Python code with Pyodide.

  • Ask HN: What ML platform are you using?

    If you want to build a web application on top of your ML project, give a shot. We designed Hal9 with ease of use for deployment and maximum compatibility with web technologies that enable you to build ML apps with React, Vue, etc. We launched a couple months ago but could use some early feedback and users. Thank you!

    BTW. If you are ever interested in helping us out, you can send a PR's to our GitHub repo. For instance, the summarize and convert blocks are here: and

    In addition, you can also use Hal9 as a standalone JS library for data analysis and skip the UX, see

    Thanks! Is actually all Vue. I like Vue better over React, just personal preference, React is great and probably better for large applications. The trickiest path is the code that executes the pipelines since it has to run dynamic JS code with dynamic parameter; made that open source to make sure people are not stuck with the product if they ever have to leave or want to scar outside the product:

    You can find more about this project at — We allow you to edit any block with JavaScript and to export the analysis as as embeddable HTML. You can also use Python or NodeJS if you need more advanced functionality.

    We are working in which is language agnostic and allows you to compose different programming languages; however, we are focused at the moment at 1D-graphs but have plans to support 2D-graphs in the coming weeks.

    We would love to help out since this is a perfect use case for; we are about to release our beta version that makes this as easy as copy-pasting code. You can find me at javier at to find some time to chat and give you a walkthrough of our code-to-api functionality.
