Lena tries to understand is a site with notes about AI, ML, data engineering, and everything that comes up alongside them when you try to understand technology a little more deeply: not only how to use it, but how it actually works.

Even after years working in tech, none of us are experts in everything — and trying to be one is probably the wrong frame anyway. Knowledge isn't a fixed body of facts you can finish accumulating; it's the willingness to keep digging into the next thing you don't yet understand. This site is not a complete course, not an encyclopedia, and not an attempt to cover every topic in the proper academic order. Topics appear not because they belong to a curriculum, but because at some point I needed to understand them myself.

I hope these notes can be useful not only to me. Maybe my way of figuring things out will feel familiar to someone else, and if something I write helps someone see a topic more clearly or understand something that did not quite click before, I will be very happy.

There's no promise here that I know everything — only an attempt to work through, honestly and carefully, the things that feel important, interesting, or finally confusing enough to sit down with.

If you'd like to get in touch — to flag an error, share a thought, or just say hi — write to me at lenatriestounderstand@gmail.com.

Lena tries to understand is an honest name for how these notes came to be.
