Error propagation dataframe using Montecarlo simulation

Asked 2020-Jul-16 at 12:47

I am doing error analysis of predictive models and I need to calculate global error, this is, I need to calculate the resultant error from propagation of indirect measurements errors. My data "df" looks like something similar to this

Where 'x' and 'y' are the measured variables, and 'x_se' and 'y_se' the standard errors of these measurements

I have used function 'propagate' from package 'qpcR' for the first row

This is one possible solution to obtain the res$summary for each row of your dataframe.

You first create a custom function my_fun that does what you were trying to do for a single row of the dataframe. Then, you apply this function to each row of your dataframe. The end result would be a list with as many elements as your dataframe rows.

QUESTION

Text extraction for FITS similar to NetCDF?

Asked 2019-Dec-18 at 15:39

I'm working with NetCDF and FITS files and I have Tika working for extracting the header text in NetCDF files but I can only get basic file metadata for FITS files. Does header text extraction not work on FITS files?

Followed this for FITS: https://wiki.apache.org/tika/TikaGDAL And am only seeing the basic file metadata not the actual text from the header.

This is what I'm using for NetCDF files (also used tika --gui to see the header text): curl -X -PUT --data-binary @age4_timeseries.nc http://localhost:9998/tika --header "Content-type: text/-t" curl -T age4_timeseries.nc http://localhost:9998/tika --header "Accept: text/plain"

I've looked through the Tika Jira and found a reference from 2012: https://issues.apache.org/jira/browse/TIKA-874

But this does not appear to have been added to Tika.

Got it working! Key nugget to know, you have to have the CFITSIO library installed before building GDAL. CFITSIO library info: https://heasarc.gsfc.nasa.gov/docs/software/fitsio/fitsio.html

Download GDAL from here: http://download.osgeo.org/gdal/CURRENT/

gunzip

tar xvf

./configure --with-cfitsio

make

make install

Run Tika as usual. Now it works like a champ!

I'd advise the following documentation: Chapter 14. View technologies, see section "14.7.4. Working with Sub-Reports":

JasperReports provides support for embedded sub-reports within your master report files. There are a wide variety of mechanisms for including sub-reports in your report files. The easiest way is to hard code the report path and the SQL query for the sub report into your design files. The drawback of this approach is obvious - the values are hard-coded into your report files reducing reusability and making it harder to modify and update report designs. To overcome this you can configure sub-reports declaratively and you can include additional data for these sub-reports directly from your controllers.

To control which sub-report files are included in a master report using Spring, your report file must be configured to accept sub-reports from an external source. To do this you declare a parameter in your report file like so:

Mongoose consider the collection name by making plural of first parameter of your model creation. So in the above case it converts Equip to Equips and looks for a collection with this name which actually does not exists. To avoid this gotcha what you can do is pass the collection name as the third parameter in you model implementation. Your model generation code will look like:

Yes there is a way. Investigate using xarray. It handles higher dimension data manipulation with ease. Filtering on one dimension is fairly trivial and then there is a .to_dataframe() method which will put your entire dataset into a pandas dataframe with multi-index.

Have a look here for an example of xarray being used with weather data.

Scanning Addresses on Windows 10 IOT on Raspberry Pi 3 takes 30 Seconds

Asked 2018-Nov-16 at 17:10

Scanning Addresses in I2C

I've been trying to scan addresses 1-128 on the ports of Raspberry Pi 3 that exist when using I2C. Note that we have 1 GB RAM, and our software always maxes it out especially during this process (actually, it is about 900K, really).

The Platform

Our Operating System: Windows 10 Iot Core Build 17744. Atlas Scientific has sensors for pH, CO2, Temperature, Conductivity and Oxidation/reduction potential (ORP). https://www.atlas-scientific.com/product_pages/circuits/ezo_orp.html Let's assume we are using the Whitebox' Labs Tentacle 3 (we are) to host 3 circuits and sensors and their associated sensors. https://www.atlas-scientific.com/product_pages/components/tentacle-t3.html

Iterating through 1-128 takes 35 seconds, which is impermissible. Also, Python on Raspian doesn't take as long. (I'm going to validate that right now).

What We've Tried

1)I noticed the scanning loop was in a static class. I thought "using" would ensure that garbage collection would clear the situation. It didn't.

1a) I rewrote it without "using", but Dispose. Same result;

2) Next I tried the IOT Lightning DMAP driver. https://docs.microsoft.com/en-us/windows/iot-core/develop-your-app/lightningproviders This had no effect on the time either.

Help Me Obi-Wan Kenobi, you're my only hope I've cross posted this to the Windows 10 IOT Support Board. Is it time to try C++?

Note

I've just tried this, but it doesn't seem to work either GetDeviceSelector()..

This result in so much time due to the exception throw then the address "SlaveAddressNotAcknowledged", the time cost depends on the number of the addresses you scan.

To solve this issue you can use WritePartial instead of Write. WritePartial can't result in an exception thrown but report the status code in the return result: I2cTransferResult, I2cTransferStatus. So save the time. Iterating through 1-105 takes about 1.2 seconds.

QUESTION

Keras - NN prediction of error in metrological measurement.

Asked 2018-Oct-31 at 13:43

I have example data which contain coordinates of points on the x-y plane (for example 2.0000 , 4.0000), next using monte carlo method, a small random error is added to those coordinates to simulate a set of points measured by a metrological machine.

This may sound trivial, but Im not really sure what to do next with this data, Im trying to build a model which predicts the error in measurement, but I have problem in visualizing the whole concept, ie. should the input layer of the network have neurons which receive real coordinates of the points and simulated coordinates, or simulated ones only? Or maybe I should estimate measurement error for each simulated point and and use it with coordinates of those points in the input layer? Also, how many neurons the network should have on the output layer and how should I interpret that data? I know this probably isnt the best description of the problem, but I am a complete begginner in this field, so any theoretical help or practical examples will be greatly appreciated.

...

ANSWER

Answered 2018-Oct-31 at 13:43

I'm not even sure if this is possible except the points are always integers in which case you can do this without neural networks. But, nonetheless, here are the answers to your question:

You should put the simulated coordinates only to the input of the model.

The output should have 2 neurons, 1 will output the estimated error of dimension x, and the other of dimension y.

The process of training is as following: you put the simulated points to the network input layer, let the network predict the error for x and y axis and then you compare the predicted results with the real (correct) ones. If the predicted ones are correct, you move on to the next sample (pair of coordinates) and if they are not the same, you update weights with backpropagation and SGD. You repeat this process for desired number of epochs, depending on your data (fine-tune number of epochs so it's not too low and not too high).

I hope this clears up things for you :)

QUESTION

"Split" an application on an embedded system

Asked 2018-Oct-05 at 11:15

Actually I'm working on an embedded project which does electrical metering. One requirement is, to split the application in two different parts:

metrological part (gets certiefied and "frozen")
user application part (for in-/output tasks; will be updated from time to time to meet future requirements)

The whole application has to reside in the internal FLASH of the controller. Another requirement is, that each part has it's own checksum that must be displayed.

This requirements are given by the authorities - the technical solution is my challenge.

Does there exist a "best pratice" for such a task?

...

ANSWER

Answered 2018-Oct-05 at 10:52

Easiest is just to ensure that you have a MCU with several flash banks. Store the certified part in one bank, and the rest elsewhere. If you are lucky, you can then have the flash programmer or similar tool generate the checksum and burn them into the same flash bank. This way you could program the "frozen" part separately from the application part, and even update the application without touching the "frozen".

I think the above would be the best practice. Otherwise, it gets much trickier, if you have to calculate the checksums on-chip. You'll have to write the CRC code and a flash burner driver etc.

So check what flash banks there are on your MCU to see if this is possible. Then check with the flash programmer tool vendor how they can help with generating a CRC, probably some CRC-32.

The file generated by MetroLog are created in the app's appdata folder, which is C:\Users\\AppData\Local\Packages\\LocalState.

When expanding the path in Windows Explorer, note that the AppData folder under C:\Users\ is hidden so you need to check "Show hidden files" in Explorer.
