### Advanced Usage
_All examples were created using the DreamShaper 7 model (https://huggingface.co/Lykon/DreamShaper/tree/main)._
#### Min. strength
Adjusting the minimum feedback strength controls how much feedback is incorporated during the passive phase, outside of the feedback schedule (i.e. when FABRIC is "inactive", before `feedback start` and after `feedback end`). This allows emphasizing the feedback during certain phases (feature scales) of the generation but still incorporating at least some of it from beginning to end. By default this is 0, so feedback is only incorporated during the active phase.

#### Negative weight
The negative weight controls how much negative feedback is incorporated relative the the positive feedback. We have found that it's generally preferrable to have lower feedback strenth for negative images, which is why by default this value is `0.5`. Increasing this increases the influence of negative feedback (without changin the influence of positive feedback).
#### ToMe settings
These settings are quite technical and understanding them is not strictly necessary for using them. Merge ratio controls the ratio of tokens that get merged: higher merge ratio -> fewer tokens -> more speed and less memory, but lower quality. Max. tokens limits the number of feedback tokens: fewer tokens -> more speed, less memory, but lower quality. The seed controls which tokens have a chance of being merged and is mainly there for reproducibility purposes. Changing the seed can alter the outcome quite significantly depending on how aggressive the other ToMe settings are.
