| Description | To train neural networks, |
...
you must collect and submit to AxxonSoft |
...
videos and images from your actual cameras taken in the same resolution and |
...
in the same conditions as in your future application. For example, if you need your neural network |
...
to work outdoors, videos must contain all |
...
weather conditions (sun, rain, snow, fog, |
...
and so on) at different times of day ( |
...
...
evening, and night). If the collection requirements for the data submitted for training the neural network model are met, and if you operate the neural network in conditions that are as similar as possible to the conditions in which the data was collected, we guarantee the overall accuracy (training in operating conditions) of neural network analytics from 90% to 97% and the percentage of false positives of 5-7%. For standard neural networks (training wasn't performed in operating conditions), we guarantee the overall accuracy of 80-95% and the percentage of false positives of 5-20%. The standard neural networks are located in the C:\Program Files\Common Files\AxxonSoft\DetectorPack\NeuroSDK directory. The requirements can be changed or added to at any time |
| General requirements for collected data |

- data, specific requirements for object images, scene, angle,

Example. It is necessary to detect a person in the surveillance area at night and during the day. - Data collected correctly:
|
...
- videos of the surveillance area, each five minutes long are submitted for training;
- the object of interest appears in the frame in each video
|
...
...
...
- nighttime conditions, two—in daytime conditions.
- Data collected incorrectly:
|
...
- videos of the surveillance area, each five minutes long are submitted for training;
- the object of interest appears in the frame in each video
|
...
...
...
- nighttime conditions, one—in daytime conditions

If the above requirements for the collection of data transmitted for training the neural network model are met, and if the neural network is operated in the conditions that are as similar as possible to the conditions in which the material for its training was collected, then the overall accuracy** of neural network analytics is guaranteed from 90% to 97% and the percentage of false positives is 5-7%. For general neural networks***, an overall accuracy of 80-95% and a false positive rate of 5-20% are guaranteed.
