【LSM6DSOX's MLC machine learning understanding】--Training data set display gadget
[Copy link]
In [Understanding MLC Machine Learning of LSM6DSOX]--Sharing of Machine Learning Usage Tutorial , I introduced in detail the detailed usage and configuration process of the LSM6DSOX machine learning module.
In [Understanding MLC Machine Learning of LSM6DSOX]--Training Dataset Correction Tool , the usage of the MLC training dataset correction tool is introduced in detail.
After collecting and correcting the motion data, we got the training data set, but in the following use, we want to see if our data is suitable. When configuring parameters, we need to see what the various statistical values of some intervals in the data set are.
Emmmmm…..It’s the same. Unico doesn’t provide us with a convenient way to view data….
So, I wrote another small tool to check the statistical indicators of the corrected data.
Simply and crudely named it " MLC Data Display Tool " it still looks like the following (well, I only have the avatar picture)..
The usage is still simple, and the interaction logic is similar to the MLC data correction tool .
After opening the gadget, you need to wait about 20 seconds for it to unpack, and then a prompt box will appear:
At this point we need to find the dataset folder that has been corrected by the MLC data correction tool , and open any txt file in it:
Then it will enter the full-screen preview state, and the overall interface layout is consistent with the MLC data correction tool .
However, the file directory and file name display area are added to the header to facilitate viewing of which data set the waveform belongs to.
There are two areas on the left and right sides of the chart . Click to switch the waveform of the previous or next data set in the current folder to display. (The unit of acceleration is g, which has been changed in the program )
You can see that there is also a vertical line following the mouse movement. The operation of this vertical line is the same as that of the MLC data correction tool . The first click records the current position as the starting position, and the second click records the end position . Then the tool will calculate according to the interval data you selected to obtain the mean, variance, energy, maximum, minimum, and peak-to-peak data of each axis in this interval, as shown in the figure below:
We can click Yes to save the data in the cal directory under the current dataset directory, which makes it easier for us to compare data from different datasets.
The saved data format is: (the acceleration unit is g, which has been changed in the program)
The exit operation is the same, just double-click the right button anywhere on the chart page.
Still the same little note:
You can exit the tool by double-clicking the right button of the mouse at any position on any chart interface .
In the chart interface, if the prompt box accidentally moves to the background and cannot be clicked, you can press the "F" key to exit the full screen in the English input method , or press the "win" key to display the status bar and continue the operation .
at last:
I hope this gadget can help you~~~
Wish you all a happy Labor Day on May 1st
