For anyone (like me) who’s unfamiliar with the term ‘gradient descent’, here’s a definition from Geeks for Geeks (Gradient Descent Algorithm in Machine Learning; last updated July 11, 2025),
Gradient descent is the backbone of the learning process for various algorithms, including linear regression, logistic regression, support vector machines, and neural networks which serves as a fundamental optimization technique to minimize the cost function of a model by iteratively adjusting the model parameters to reduce the difference between predicted and actual values, improving the model’s performance. Let’s see it’s role in machine learning:

Geeks for Geeks follows up the definition with what appears to be a learning module.

Hi friends, A quick pulse check as we slide into fall: the September Vancouver AI meetup is around the corner, the dataset just landed, and BC + AI is taking a clear shape.
1) Sept 24 [2025] Vancouver AI Meetup: Just around the corner!
Twenty‑one gatherings in a row and still getting weirder, deeper, kinder. We’re back at H.R. MacMillan Space Centre on Wed, Sept 24, 6–10 PM. It’s a night where code meets culture and nobody postures… short field reports, honest demos, hallway debugging, a few tricks up my sleeve.
If you’re coming, grab a spot so I can get the headcount right; I want the food generous and the bar properly stocked when the ideas start flying.
2) AI Hackathon Round 4 — the dataset just dropped.
1,000 Canadians on music: how we discover it, how formats shaped us (vinyl → cassettes → CDs → streaming), and how it feels when AI‑generated songs slip into the mix. Not just stats—stories, theme songs, guilty pleasures, resistance. We cleaned it, mapped sentiment across 3,000+ text entries, and kept the edges so you can read the grain. Turn it into something useful: an agent that argues for/against AI tracks, a generational format map, a memory palace of theme songs, a zine, a visualization, a performance.
We’re formalizing what’s already alive: a member‑led commons for BC: coastal, cultural, carbon‑smart. Multi‑modal, multi‑cultural, radically local, future‑facing. It’s community infrastructure you can touch: a Funding Directory (200+ programs, updated and battle‑tested), an Ecosystem Map to find collaborators fast, the ongoing AI Hackathon series and resources, a members‑only WhatsApp lounge for the real talk, a monthly newsletter that’s signal over noise, and an open line when you’ve got questions, leads, or constructive rants.
Join if you want to help steward public‑good tools, connect across regions, and grow a people‑first AI culture rooted in this place
See you under the UFO roof on the 24th [September 2025],
KK & the BC+AI crew
For the meetup, the price of an ‘Earlyworm’ ticket (five are left) is $52.50 until 11:39 pm PT on September 17, 2025. The standard ticket is $63.00.
There’s more than one tier for membership in BC + AI starting with a free membership (newsletter only) and moving onto Individual for $240 and Student for $80 with more packages available.
