hi,  
first step to my code is create a encoder , my data set is like these {%Y-%m-%d %H:%M:%S.%f , float, float}

> 2018-10-06 00:00:00.033,-0.160,-0.075  
> 2018-10-06 00:00:00.036,-0.155,-0.070  
> 2018-10-06 00:00:00.039,-0.160,-0.070  
> 2018-10-06 00:00:00.042,-0.175,-0.065  
> 2018-10-06 00:00:00.044,-0.180,-0.055  
> 2018-10-06 00:00:00.047,-0.185,-0.050  
> 2018-10-06 00:00:00.050,-0.170,-0.050  
> 2018-10-06 00:00:00.053,-0.155,-0.040  
> 2018-10-06 00:00:00.056,-0.175,-0.040  
> 2018-10-06 00:00:00.058,-0.180,-0.055

to encode my data set:

- To the date : DateEncoder
- To float:RandomDistributedScalarEncoder

but the probleme in my data time is with Millisecond and the parameters of DateEncoder is with Day and hour.  
so my question is to solve this probleme:  
\*I must create Model Parameters Or Create an OPF Model ?  
\*change the parameters of DateEncoder ? (how)  
I use this link to learn:[HTM](http://nupic.docs.numenta.org/1.0.5/)  
thanks

If your dates are in milliseconds, the date encoder is not going to produce any useful semantic encodings. Milliseconds are not “human scale” time periods.

Model params are used to create all types of models in our examples.

So in my case, what type of encoders could I use to my data set

Scalar encoders for your scalar data, but what does your data represent? When you plot this data, do you see patterns?

Yes, I will use scalar encoders for my scalar data, but I 'm confused about the type of encoders for my data time because my time is with millisecond

You don’t encode time because it is at sub-human scale. Humans don’t semantically understand sub-second timing.

Have a look at this, It is a similar data type.

> Hi, Matt taylor First of all, I am really appreciated for your lecture (HTM School). It helped me a lot. I want to use HTM for automatic seizure detection using EEG data. and there are some projects dealing with EEG data. But I want to use not a single channel. To detect seizure, I have to use many channels and I am going to use not a raw data but features include Power spectral density. I don’t know how to use HTM for these. Do I have to use HTM regions for each features? Then I need hun…

hi matt,  
I try your exemple [https://github.com/rhyolight/online-anomaly-detection/tree/master/mat\_src](https://github.com/rhyolight/online-anomaly-detection/tree/master/mat_src) , and I make some changes in the model\_params the update of the parametrs of SP and TM but have this error :  
return \_engine\_internal.Network\_addRegion(self, \*args, \*\*kwargs)  
TypeError: **init** () takes at least 3 arguments (3 given)

Unfortunately that code is pre NuPIC 1.0, so it is broken. You should be able to lift the model parameters from it and apply them to your code.

I should mention the [OPF Quickstart](http://nupic.docs.numenta.org/stable/quick-start/opf.html) in case you haven’t seen it.
