Descend

Interactive machine learning demonstrations. A clickable graph allow you to input data. Use the controls buttons to begin a gradient descent algorithm (TODO: more fun things!). Visualie the current model fit alongside the best analytic fit, with stats such as model cost history and a graph displaying the cost for nearby parameter values.

Here's a screenshot:

Models

• Linear Regression (done)
• Logistic regression & classification (todo)
• Autoregressive model (todo)
• Basic neural net (todo)

TODO

• Adjustible learning rate parameter.
• Add non-linear terms (orders, sin).
• Add trace to costscape to show history of model param estimates
