Equations using the matrix notation for a simple artificial neural network

Update on 2020.01.30 16:58 IST:

I have taken the document offline. Yes, it was too incomplete, tentative, and in fact also had errors. The biggest and most obvious error was about the error vector. 🙂

No, no one pointed any of the errors or flaws to me.

Yes, I will post an expanded and revised version later, hopefully in the first week of February. (I started work on this document on 24th Jan., but also was looking into other issues.) When I am done, I will delete this entire post, and make a new entry to announce the availability of the corrected, expanded and revised document.

The original post appears below.

Go, read [^].

Let me know about the typo’s. Also, errors. [Though I don’t expect you to do that. [I will eat my estimate of your moral character, on this count, at least for the time being.]]

I can, and might, take it out of the published domain, any time I want. [Yes, I am irresponsible, careless, unreliable, etc. [Also, “imposing” type. Without “team-spirit”. One who looks down on his colleagues as being way, way, inferior to me.]]

I will also improve on it—I mean the document. In fact, I even intend to expand it, with some brief notes to be added on various activation- and loss-functions.

Eventually, I may even publish it at GitHub. Or, at arXiv. [If they let me do that. But then, another consideration: there are physicists there!]


A song I like:

(Hindi) “कभी तो मिलेगी” (kabhee to milegi)
Singer: Lata
Music: Roshan
Lyrics: Majrooh Sultanpuri

[Credits happily listed in a mostly random order. [The issue was only with the last two; it was clear which one had to appear first.]
