Pretty cool! If you haven't already, share the article in #C8NUSGWG6

Wonderful!! It may be worth exploring in combination with @UDRJMEFSN's https://github.com/cnuernber/tmdjs (DataFrame and Numerics for ClojureScript). tmdjs does seem to work well with Scittle (currently this is supported by the https://github.com/scicloj/scittle, but should be also doable in the original Scittle itself using the new https://clojurians.slack.com/archives/C034FQN490E/p1683142333100929?thread_ts=1682156428.196199&cid=C034FQN490E). I'd be happy to help exploring that.

This is amazing @UP7RM6935!

Didn't realize mnist could be reduced down to:

(defn sigmoid [n] (/ 1.0 (+ 1.0 (Math/exp (- n)))))
  
  (defn feedforward [inputs weights biases]
    (for [[b ws :as _neuron] (map vector biases weights)]
      (let [weighted-input (reduce + (map * inputs ws))]
        (sigmoid (+ b weighted-input)))))
  
  (defn argmax [numbers]
    (let [idx+val (map-indexed vector numbers)]
      (first (apply max-key second idx+val))))
  
  (defn digit [pixels]
    (-> pixels (feedforward w0 b0) (feedforward w1 b1) argmax))

That's what I love about clojure/lisp though. Implementing a solution in Clojure makes the whole problem easier for me to understand. Thanks for putting this together

> OpenAI: Hey there son, you gotta license for those there sufficiently powerful Clojure functions?

I kid, I kid

@U066L8B18 cool, tmdjs looks like a lifesaver for tackling "real" data tasks in JS

thanks @U050PJ2EU! i was also surprised by how concise the inference could be. a friend showed me his c# implementation and i was like, oh, this seems like something i could actually figure out, at least at a basic level, without reading a whole textbook haha

@U9G5NDV4Y haha yeah it's a bit of a hack, i gave up on mobile after a few attempts to make the https://github.com/matthewdowney/clojure-neural-networks-from-scratch/blob/main/mnist-scittle/canvas.js file handle the mobile touch / move events

I'm curious about changing this into a text completion API, for like an omnibox with NLP completion over a narrow domain, and have it running right in the browser

Wow that is cool!
