will it work for multivariate time series classification for example mixture of categorical and continues data? #42

will it work for  multivariate  time series classification for example mixture of categorical and continues data? 
for example at time t1 we have observation: red, 2.4 , 5, 12.456 and time t2: green, 3.5, 2, 45.78; time t3: black, 5.6, 7, 23.56; t4: red, 2.1, 5, 12.6 ?

I am not sure what those 3 numbers mean here. We treat observations for each class independently if that suite your case then yes. But I can not really say without knowing more about the problem statement. Multivariate could mean a lot of things.

Multivariate could mean a lot of things.

Let's say any Multivariate example on your choice

Hi @Sandy4321, it would help if you make your example more concrete

As you asked I clarify Then t1 is yes, t2 is yes, t3 is no, t4 is no Can your code classify this kind of data?

Let's say we have 2 classes yes and no

You can train a classifier your observation samples, in our cases, those are results from SSD detector, which give a score between 0 and 1 for each class, in our case that 24 classes, in your class, you have two classes (yes, no) train a binary classifier then you can apply label smoothing formulation.

basically you will need a way to translate categorical data into 0-1 by sudo-probabilistic classifier

Sandy4321 commented 4 years ago

what is it : sudo-probabilistic classifier? can you share link pls?

gurkirt commented 4 years ago

In our case that is SSD detector.

Sandy4321 commented 4 years ago

Not clear what can be used for tabular data Can you help find web link for sudo-probabilistic classifier for tabular data

Random forest is supposed to be good for categorical data. But, I am no expert in that domain.
