Keywords

πŸ’‘Fine-tuned model

A fine-tuned model refers to a machine learning model that has been trained on a specific task after being pre-trained on a larger, more general dataset. In the context of the video, the term is used to describe the process of customizing a model for AI image generation, such as style, character, face, or object models, to generate images that fit a particular style or represent specific subjects.

πŸ’‘Illustration style

An illustration style is a distinctive visual art technique or approach that characterizes an artist's work. In the video, the speaker discusses creating a custom illustration style by training a model to generate images that match a preferred visual aesthetic. This is exemplified by the speaker's attempt to train a model to produce black and white illustrations.

πŸ’‘Quantity of images

The term 'quantity of images' refers to the number of images used to train a machine learning model. The video emphasizes the importance of uploading a sufficient number of images, ranging from four to 128, to ensure the model learns effectively. The speaker mentions uploading 70 images to train their model, highlighting the significance of this step.

πŸ’‘Consistency

Consistency in the context of training a model means that the uploaded images should share a common theme or style. This helps the model to understand and replicate the desired style without confusion. The video script mentions the need for consistency to prevent the model from being misled by a diverse range of unrelated images.

πŸ’‘Variety

Variety, in the context of the video, refers to the range of different subjects, poses, and angles included in the training images. The speaker stresses the importance of having a variety of images to teach the model how the desired style should look across different subjects, such as people, animals, and objects. This contributes to a more versatile and adaptable model.

πŸ’‘Model training

Model training is the process of teaching a machine learning model to perform a specific task by feeding it data (in this case, images) and adjusting its parameters based on the results.
