Friday, June 14, 2019 (Planning of last days of data collection, Subgroup divisions)¶
Participants: Luana, Maren, Malin, Sophia, Richard, Josefine, Axel, Ulf
Updates¶
Labelled Data¶
How many (labelled) pictures do we need?
we don’t always have all asparagus classes (not evenly distributed)
only one week left
having more data won’t hurt
what fraction of data might be labelled? (prob. less than 10%)
semi supervised learning techniques might recommend how much labelled data we need
Schedule for trips to Rheine to collect labelled data
Monday 17.06 : Richard, Josefine
Tuesday 18.06 : Sophia, Luana
Wednesday 19.06 : Richard, Malin
Thursday 20.06 : Maren, Luana
Friday 21.06 : Sophia, Josefine
still open: 14., 15., 16. & 22., 23.
Problems and Thoughts¶
Ideas of bucket-wise collection
don’t think about perfect classification piecewise but bucketwise
find solution for problem, that even sorted asparagus is sorted by human eye and not perfect as the machine would need to learn the classes
use a system where you update while classifying
apply this idea to features and not images
After data collection
have subgroups with smaller tasks
try all sorts of possibilities for sorting (ANN etc.)
Curvature extraction
actual asparagus sometimes S-shaped, bump at end etc.
method should be able to detect different kinds of curvature (return all asparagus that is not totally straight as curved)
User interface design
how should the user interact and also influence the sorting-process?
if people here are interested in this, we include it (but it is no must)
maybe difficult to say right now while we do not have an algorithm or anything yet
decision postponed to later date
Subgroups¶
Decision app
Michael
gives some information on the shown asparagus picture
has only yes and no buttons
Documentation
Katha
(gather more literature)
Feature extraction
flower, color and maybe rust still problematic
Framework
already start it and then implement it as soon as feature extraction is done
Literature research
rather a task distributed to all subgroups
Organisatorial stuff
don’t have too many subgroups
distribute groups and the assign more than one task to them
Report
already start the report on our study project
not only write what we have done but also why we tried it (make this very clear why we thought this is a good idea), how we arrived there and also put in what failed
generally good: before you start something, write down what you expect/plan to gain from it and always update what worked and what didn’t
around 100 pages expected, 10 pages per person (no final number)
