For classifiers you have to have predefined classes, which I guess would be 'Ok', 'Angry' and 'Happy' Alfred. If you have SVM classifier, you would fit the current data points and see what the SVM classifies that point to. I guess that's the standard procedure we all follow.
But I guess my concern lies with the classifier that we make, which I assume is using K mean approach. Using the dissimilarity matrix you choose the class to which its least dissimilar to. My previous message hints the error with deciding the classes, which by the way are formed from Training data points. But the inherent variability is too high, that you would end with so many wrong classifiers with the Linear classifiers that you plan to develop that it may give very absurd results.
Hi VisteonIntern! Thanks for your critical comment and your interest on my app! I will try to explain you my
thoughts :-) The first thing is i didn't use k-means
which is a clustering technique which clusters a set of
datapoints in a predefinded number of clusters and you
are absolutely right that it is hard to determine the
number of clusters before. Instead I used k-nearest
neighbour classifier (I admit that the two names can
esily be confound). Since I don't know if you are
familiar with the concept of classifiers I will give you
a short introduction: A classifier works as follows:
1. Step: trainig phase - in the training phase let me say you have to create the "world" with its elements the classifier should know. Let me give you an example: If you want to classify music acording to genre and you have four genres (classical, jazz, rock, rap), then you
have to tell the classifier what are the characteristics
of the different genres. So you will take many music
clips (samples), calculate some features (beats, onsets,
pitch, timbre ..) and train the classifier
2. Step: classification phase: now you will show the classifier a new music piece (sample) which he has never seen before. This peace will be compared with the peaces that were used in the training phase. According to the operation mode the classifier will then find the genre class to which the new peace belongs by mathematical
calculations. In case of k-nearest neighbour the euclidean distance from the new sample to all samples
from the training phase is calculated. According to the
choosen number of "K" the k nearest samples from the
training phase to the new sample are considered. If the new sample is mostly e.g. near class "classical" the
classifier wil return class classical as result for the new sample. ---- now to your approach to use fuzzy logic. I think fuzzy logic is also a classification technique, but I must admit that I am not so familiar with it but I know that fuzzy logic is mostly used when there is no mathematical description of the "world" but a verbally like in speech recognition or automation of technical processes. -- I hope I could clarifiy your doubts a little bit ;-) if not feel free to ask me again or to tell me what you think is wrong with my approach!
Hi , I don't mean to sound too pedantic, but I doubt if K mean Clustering will give you any reliable results! My personal choice would definitely be Fuzzy Logic for what you intend to do.
K mean being sensitive to initial number of clusters you would choose, it will automatically try and reduce the in-cluster variability trying to reduce the inherent variability that the driver would have, hence leading too absurd results.
I also cant logically convince myself , what distance matrix to use and why!
If you don't mind please do share some technical details, your approach seems to be interesting, but flawed.
Strange ... it is the 1. of Juli 7:37 and the contest is still running! I am confused!
I've just seen. As I've written a very good job. A pity that the contest ends today. and I must say I really enjoyed both your applications and your comments and suggestions. I hope to see you in future contests:). Greetings!
Hi my frnd lars,
Today is the final day of this contest.i think we all miss each other from 2moro onwards.Last 2 months we stay here like a community.Anyway its time to leave.Thx for ur support & valuable comments. Wish u all the success & good luck.Hope we can keep in touch. Thx again my frnd
Hi Lars! Thanks for your welcome :) I'm waiting your latest app that sevennine comments. good luck dude! ;D
Hi Lars, good to hear you are working on another app :) the contest ends by midnight - CET (Central European Time) Good luck for the final spurt! :)
Hi Lars!! ugh ... I know. I have been missing due to exams by a very long time! So I was under the obligation to raise my applications soon. Well, now I have enough free time, so I'll get to work on the update of my applications and discuss all your Tabajares (I've seen that there are some very good things:).) Right now I'm busy with paperwork at the university, but tonight I promise to catch up! :)
Thx for your comments. Its always valuable for me.
Hi Lars, do you use then the Loader or URLLoader class to load your request? You should use URLLoader. Stupid question, but your webspace does support PHP? Have no more ideas at the moment...
Hi Lars!! Thanks for your comment :) Tonight I'll see your latest works and I comment it. See you! ;)
Ah, problem fixed - super! And a really clean/elegant GUI. Do you work for Apple?
Yes in a sql database.. Thanks for your comment and ill be adding that skip button in a minute..
sorry misspelled your name..
lats, i see that you just tested my app, i know its just a basic app but still would like to know you feedback.
of course I did use papervision as this stuff is working fantastically with great performance.
Hi lars, thx for visiting my profile.ur valuable comments expecting
Yep, i've tried with 'local files' and 'network only' in publish settings, but not tried do load a map in player without apikey. Sorry by missing comments and Thank you!! :)
Yes you are right! A forum is really missing here! Ok I will add you on Facebook and have a look at the code. I will right you as soon as I found out something.
I think that the problem is because i've created in flash, and the main app-player was created in flex, so it can create security sandbox issues.
Hi. I've reactivated my facebook account: http://www.facebook.com/profile.php?id=100000363039260
I'll upload some part of my code (it's big).
This community really needs a forum, like nokia "calling all inovators".
Ops, i've deleted my account, do you have twitter? I can sent you a DM if we follow each other. :)
Lars. How do you could show another google map inside of your application? Into to my app, new maps disappears! I'm creating the same flow as you "click details, show map", in test mode they works, but in play don't. =/
Lars!! Please !! Upload your application quickly that I was late to see it :'(....
Ok, Lars (here, 6:30pm), i'm recreating the interface deployment in html and air to try to find a workaround to sandbox issues. I hope that i find it, so i'll contribute with the possible solution. I'm waiting for a contest team response. Good job! :)
Yep. I'm receiving some erros too. The app-player don't show another google maps and theese maps are fully functional on air, test and swf files on my computer. I've sent an email to contest team to provide the sources of app-player, it can help us to fix some erros, i think.
I've made the buttons for my app.
You can download a PNG (FireWorks CS4 version, editable) at http://www.ederlima.com.br/arquivos/flash/vw-app-my-ride-ederlima-buttons.png
The font type is "VolksWagen HeadLine" (Regular, Bold, 20)
Hi All, best thing to have is a browser like iTune since we use our iPods.
lars you're absolutely right. Great idea! ;)
Hi Lars, what kind of browser and flash version do you use? I can't find any "strange" behaviour in your app.
Hi Lars, we will have new driving profiles by next week. Stay tuned!
how is it going with your coding? :)
It not my first time coding an app. But it is the first time in flash :-(
Great, I'm looking forward to it! Is it your first time coding an app?
Wow, that would be awesome lars! maybe you are the first one submitting an app! I am excited!
Hi Annett. Yes I have some more! At the moment I am coding my first app. Hope it will be ready today.
Hi Lars! Cool idea, do you have some more?
