This suggests that it's likely the model's capacity is nowhere close to being reached.</p><p>This also serves as a demo of an extremely inefficient style transfer method: train the characters, and then train on lots of unrelated styled images.</p><h2>Usage</h2><p>This Hadamard Product LoRA requires installing <a target="_blank" rel="ugc" href="https://github.com/KohakuBlueleaf/a1111-sd-webui-locon"><strong><u>an extra extension</u></strong></a> to be used in the Web UI.</p><p>The style itself doesn't have a trigger word. For the characters, below are the character tags and respective top 20 related tags.</p><pre><code>Sakuragi Mano,
