Handball Log updated for the month of May

We have been continuously exploring how to write files, utilizing the same method as in April. Below are notes that we took, documenting this process.

May 5

• We used the last years desktop scenario for this (motor-imagery-bci-2-classifier-trainer.xml)
• The timeout box is useful in stopping the scenario
• The console is the box of info
• The percentage in the console was 52.52%.
• They recommended that if it was less than 65% we should record a new scenario
• I’ll record a new data file using the 1-acquisition scenario
• I’ll do a full timed one, not just one minute
• Recorded a full file
• Tried running it. The timeout stopped it after 60 secs, so I changed it to 500 secs (8 minutes and 20 seconds)
• Even though! The one minute cut off data yielded a 57.56%. Already better than the old one, even if this is just a cut off piece!
• Hmm. the finished result is 55.59%. That means that the one minute cut off was better.
• Perhaps its because i recorded the scenario in a noisy room, and i was a bit restless throughout. Next time i’ll try to record a new scenario with less noise.

May 10

• 54.89%, with the new scenario that brian recorded.
• We can try cutting it to one minute and see if its better.
• We need at least 65%, ideally.

May 17

• Cut it to 60 seconds. It worked better, 60.5%. Yay.
• Were using that one.

May 19

• Cut it to 200 seconds. Nope.
• Cut it to 30 seconds. 64.4%. Doesn’t prove anything cuz first 30 seconds of data is only nothing.
• I’m trying again the old scenario, with 500 seconds. Too bad. 55.59 is great.

May 24

• Tried motor-imagery-bci-4. Shows everything. Gonna use this at presentation.
• Lets try SVM once. I set it to brian’s recording for 200 seconds.
• 56%.
• Lets try the same thing with 120 seconds, two minutes.
• Lets try PLDA. i set it to Brian’s recording for 120 seconds.
• 56% again.
• Lets try probalistic shrinkage thingie. Same settings.
• 55%.
• Lets try shrinkage LDA. same settings.
• Also 55%. Back to regular LDA.
• 56%.
• Tried moving up partitions for k-fold test to 10.
• Same 56%.
• Tried moving it down to 5.
• Also 56%.
• Tried moving it up to 15.
• Did not help. Moved it back to 8, lets see.
• Moved back to 6, lets see
• Ok this clearly doesnt influence the data. Let it at 8
