Weekly schedule is here: https://ecs.victoria.ac.nz/Courses/COMP421_2015T2/LectureSchedule

Put any working code you like into (e.g.) Week1-Perceptrons or similar folder. Short is good, maths is good, pretty pics of success are really good - just get it out there for everyone to vibe off as they see fit.
