1. Simplest AI Trick in the Book
Normalised Tunable Sigmoid Function
Dino Dini NHTV University of Applied Sciences
2. Normalized Values Are Useful
For example:
● Utility calculations
● Input management
● Control systems
● Tunable parameters
3. Analog Input
-1 0 1
Abstract away the device dependent positional values
(0 to 255? -1024 to 1024?) and normalise.
Normalised values are much easier to work with.
4. Example:
Analog Input - Left / Right Rotation
Input 1024 1
Normalizer
Device -1024 -1
Movement 5 Rotation
Degrees per
Driver -5 Frame
5. Example:
Analog Input - Left / Right Rotation
Input 1024 1
Normalizer
Device -1024 -1
Movement 5 Rotation
Degrees per
Driver -5 Frame
9. Linear relationship
Degrees rotation per frame
I also want full range
Control input (left - right)
10. Linear relationship
Degrees rotation per frame
Full Range
Greater sensitivity
Control input (left - right)
11. Example:
Analog Input - Left / Right Rotation
Input 1024 1
Normalizer
Device -1024 -1
Sigmoid 1 5 Rotation
Movement
like Degrees per
-1 Driver -5
function Frame
12. Example:
Analog Input - Left / Right Rotation
Input 1024 1
Normalizer
Device -1024 -1
Sigmoid 1 5 Rotation
Movement
like Degrees per
-1 Driver -5
