[Assignments]. hw6 has been posted.

There was an issue with embedded commas in the name field of the .csv files. The parse_csv() function did not handle this correctly. I have edited the .csv files to remove the offending commas. You should use the revised files. Note: the prediction results from the learning algorithms did not change much after fixing the commas. I would expect that it would make a difference when running predictions on the test data.
If you manually update fields like age, you may edit the .csv fils and submit those files along with hw6.ipynb file.
You may use other python modules, like numpy or pandas, to modify the data. As someone pointed out, the aima code does not use the dataframe format. Therefore, you can convert the titanic.examples list to the desired format, manipulate the data, and then convert it back to the list format used by titanic.examples.

CS 570 project assignment is also available in [Assignments]. So far three have been submitted and approved.
