### About Us

We're a loosely-knit stochastic federation of people who like Noisebridge and like machine learning. What is machine learning? It's broad field that typically involves training computer models to solve problems. How can you participate? Join the mailing list, send an email and introduce yourself. Show up to the next meeting, share your thoughts. Participate in projects or start your own. Go to workshops, write code at workshops, learn stuff, give workshops of your own! All are welcome.

### Next Meeting

- When: Wednesday, 8/3/2011 @ 7:30-9:00pm
- Where: 2169 Mission St. (back corner classroom)
- Topic: Deep Belief Nets Part I: PyBrain Installfest!
- Details: We're going to install PyBrain and check out their Restricted Boltzmann Machine implementation.

### Talks and Workshops

We've given lots of workshops and talks over the past year or so, here's a few. Many of the workshops we've given previously are recurring and will be given again, especially upon request!

- Intro to Machine Learning
- A Brief Tour of Statistics
- Generalized Linear Models
- Neural Nets Workshop
- Support Vector Machines
- Random Forests
- Independent Components Analysis
- Deep Nets

### Code and SourceForge Site

- We have a Sourceforge Project
- We have a git repository on the project page, accessible as:

git clone git://ml-noisebridge.git.sourceforge.net/gitroot/ml-noisebridge/ml-noisebridge

- Send an email to the list if you want to become an administrator on the site to get write access to the git repo!

### Future Talks and Topics, Ideas

- Restricted Boltzmann Machines (Mike S, late August)
- Deep Nets w/ Stacked Autoencoders (Mike S, September)
- Generalized Linear Models (Mike S, September/October)
- Graphical Models (Tony)
- Working with the Kinect
- Computer Vision with OpenCV
