The regression can give the possibility for example in metals for a phase to be martensite, which can be 20%, and compared to the other potential phase, when the algorithm is fixed to assign values < 50% to 0, then from regression the algorithm performs classification (the output is that the phase is not classifies as martensite). |

| Comment | The function that describes the real geometry of the tip, and more specifically the tip's area, is called Tip Area Function. In order for the nanomechanical properties to be calculated correctly, a calibration in order to obtain the Tip-Area-Function must be contacted prior to every set of measurements. |

| Elucidation | The distance the indenter tip moves away from the sample surface before the indentation starts and after every single indent within a single nanoindentation measurement. |
| Comment | Typically and empirically the move back value minimum possible threshold that a user could use is ten times smaller than the interindent spacing, however most of times the value is set to a higher number because the samples are not always perfectly flat or might be tilted, which can set up a risk of the indenter tip crushing on the sample surface while moving into the nanoindenter chamber between the current and the next nanoindent location (which has distance the interindent distance) within a single nanoindentation measurement. |

| Example | When the trigger force it is exceeded and a displacement controlled protocols is selected with specific target depth, then after that trigger force the indenter will start to count the displacement for reaching the target depth threshold and stop the measurement. In case the trigger force is relatively high, then the indentation tip will already have penetrated the sample surface in a couple of nanometers, thus technically the final nanoindentation depth will exceed the threshold of target depth control parameter. |
