Lab #1, due Tuesday, September 16 at beginning of class
Lab #2, due Tuesday, September 23 at beginning of class
For Python you can use apples-oranges.npz
In : import numpy as np In : d = np.load('apples-oranges.npz') In : d.keys() Out: ['oranges2', 'apples2', 'apples', 'oranges']
Lab #3, due Tuesday, October 21 at beginning of class
Matlab code are as separate files below.
For Python you can use
Lab #4, due October 9th at beginning fo class
Matlab code and data for homework
- hopnet.py - python version of the above code as one file (with run, genpat, and corrupt methods)
p = np.load('patterns.npz') face,hi,X = p['face'], p['hi'], p['X']
# if you load patterns.mat, use: p = scipy.io.loadmat("patterns.mat") face,hi,X = [p[k].reshape(10,10).T.reshape(100,1) for k in 'face','hi','X'] # line above converts Fortran to C ordering
Lab #5, due Thursday, Oct 30 at beginning of class
- foldiak scripts (zip)
