DLS Course 2 Week 2: adam is the worst algo

Are you sure you didn’t alter any of the other parts of the notebook other than the code you need to write? Here’s what I see from the Adam section:


The accuracy I get from Adam is 94%, which is greater than the 71% accuracy I see with plain minibatch or with momentum. Note that 71% is also higher than you get even from Adam.

If your functions pass the test cases in the notebook, the only thing I can theorize is that you modified some other part of the notebook to create this effect. You might want to start with a clean notebook and just “copy/paste” over your completed code and see if that makes a difference. There is a procedure for that documented on the DLS FAQ Thread.
