Decoding the Essence of Text Inversion Training

The core aim of Text Inversion training within the realm of the Diffusion model is to fine-tune it in such a way that a specific embedding yields outputs closely resembling the input image.

This section is dedicated to demystifying the foundational logic of Text Inversion, spotlighting the pivotal role of embedding and elucidating the fundamental steps entailed in the training process.

The Pivotal Role of Embedding

  • Understanding Embedding: In artificial intelligence and machine learning, an embedding is a sophisticated method used to translate discrete variables (like words) into vectors of continuous values. These vectors, residing in a sprawling high-dimensional space, can encapsulate and reflect various relationships among variables, including semantic similarities.
  • Distinguishing Name from Prompt: In the Text Inversion paradigm, the term we assign (for instance, “ajaj”) functions more as a prompt rather than just a name. It signifies the embedding of specific image features we aim to replicate. Initially, this embedding is virtually blank, devoid of sufficient data to steer the Diffusion model towards generating the target image.

The Training Process Unveiled

text inversion
  1. Transforming Noise into Image: The training kicks off with Stable Diffusion transforming the chosen training image (take, for example, a photograph of Angelina Jolie) from a mere array of pixels or “noise” into a structured image. Embedding acts as the beacon throughout this transformation, guiding the noise towards forming coherent images.
  2. Image Synthesis and Evaluation: The Diffusion model endeavors to craft a preliminary image rendition by eliminating randomness from the noise, guided by the current state of embedding. It then benchmarks this nascent version against the original training image to discern discrepancies.
  3. Calculating Loss: The disparity between the crafted image and the training image is quantified as a loss value, serving as a metric of difference. A diminished loss value signifies a closer resemblance between the generated image and the training image.
  4. Iterative Refinement: Anchored by the loss value, Stable Diffusion persistently tweaks the embedding. Through this iterative cycle, it steadily narrows the gap between the generated and training images until an optimal congruence is achieved. At this juncture, the embedding effectively instructs the model to produce images that mirror the training image with high fidelity.

Through this exposition, it becomes evident that Text Inversion training is an iterative endeavor focused on refining the embedding. This process seeks to optimize the Diffusion model’s ability to generate images that not only echo but closely align with the training image.

It delves into a profound understanding of the training image and iteratively modulates and enhances the embedding. This meticulous adjustment is aimed at elevating the quality and likeness of the generated images, ensuring they bear a striking resemblance to the original training image.

Launching Text Inversion Training: A Comprehensive Guide to Setup and Fine-Tuning

Strategic Learning Rate Adjustments

A seasoned practitioner from Reddit has shared a learning rate strategy that has proven effective across various datasets:

  • Initial Phase: From step 1 to 10, a higher learning rate of 0.05 kickstarts the capture of fundamental features.
  • Mid-Stage Tuning: The learning rate is then tapered to 0.02 for steps 10-20 and further to 0.01 for steps 20-60, facilitating gradual refinement.
  • Late Fine-Tuning: At step 3000 onwards, the learning rate is minutely reduced to 0.0005 for precision fine-tuning until training’s end.

Implementing the Strategy

  • Default Learning Rate: While a fixed learning rate, say 0.05, might suffice generally, adopting a dynamic adjustment strategy could yield more nuanced control and superior outcomes.
  • Dataset-Specific Trials: Experiment with various learning rate strategies on your specific dataset to discern the most effective settings for your project.

This staged learning rate adjustment strategy ensures the model is fine-tuned at different phases, promoting swift convergence and minimizing overfitting, thus paving the way for satisfactory outcomes. Remember, the learning rate should be flexibly adapted based on the model’s feedback and training progress for optimal results.

Additional Considerations for Optimization

  • Batch Size and Gradient Accumulation Steps: The balance between batch size, affecting training speed and memory demand, and gradient accumulation steps, required for maintaining training stability, is delicate. Default settings are recommended unless specific speed improvements are sought.
  • Dataset and Log Directories: Accurately setting the dataset directory ensures model access to training images, while the logs directory should be set for convenient training progress tracking.

Prompt Template Selection and Customization

Within A1111, a plethora of templates awaits, offering a rich foundation for training customization. These templates are neatly housed in the ‘textual_inversion_templates’ folder within the A1111 root directory.

Max Steps

The term “max steps” delves into the heart of the training process, signifying the upper limit of iterations the model undergoes. Throughout these iterations, the model embarks on a meticulous journey to minimize the disparity between the generated imagery and the intended target image.

While the system might default to an ambitious ceiling of 100,000 iterations, practical experience suggests a more moderate benchmark—around 3,000 steps—usually suffices to achieve commendable training outcomes.

Exorbitantly high iteration counts risk overfitting the model, potentially leading to exaggerated representation of specific features. However, an elevated iteration limit shouldn’t cause undue concern. The training framework is designed with flexibility in mind, allowing for the training to be paused or concluded at any juncture.

Optimizing Image and Embedding Save Intervals

  • Save an image to log directory every N steps: This functionality instructs the model to archive the generated image at specified intervals, depositing it into the log directory. This archival process is instrumental in visualizing the model’s evolution and its proficiency in capturing the desired imagery. Tailoring this setting to a smaller value enhances visibility into the training’s immediate impacts, allowing for real-time adjustments and insights.
  • Save a copy of embedding to log directory every N steps: Echoing the principles of image saving, this parameter schedules periodic saves of the model’s embedding state throughout the training journey. This systematic preservation is crucial for evaluating the model’s alignment with the training objectives over time. By opting for more frequent saves, you avail a broader spectrum of embedding iterations to scrutinize. This granularity enables a meticulous selection process, identifying the most effective embedding that encapsulates the essence of the desired output.

Training Speed Optimization Options

  • Use PNG alpha channel as loss weight: This innovative approach proposes leveraging the PNG alpha channel to dictate loss weight, potentially accelerating the training process. However, it’s accompanied by the need for meticulous dataset preprocessing and parameter adjustments. Given its complexity and the requisite fine-tuning, it’s prudent to proceed with caution, considering this option only when you’re equipped to manage its intricacies.

Harnessing Extra Features for Enhanced Training

  • Save images with embedding in PNG chunks: Activating this feature will incorporate embedding details directly within PNG images generated during training. This serves as a valuable tool for monitoring and managing the training progression, offering a transparent view of the embedding’s evolution and its influence on image generation.
  • Shuffle tags by ‘,’when creating prompts: The strategic shuffling of tags within the prompt, achieved by randomizing their order, stands as a method to dilute the dominance of any single term. This harmonization ensures a more equitable representation of attributes in the generated images, potentially elevating the model’s output quality.

Deliberate Sampling Method Selection

  • Balancing Random and Deterministic Sampling: The default endorsement of random sampling underlines its utility in fostering diversity and exploration within generated images. However, the pivot towards deterministic sampling by a segment of the community underscores its value in enhancing the stability and reproducibility of training outcomes. This methodical approach to sampling can be particularly beneficial in scenarios where consistency and predictability of results are paramount.

Launching the Training

Once all the parameters are set, click the “Train embedding” button to start the training process. The training can be paused and restarted at any time, and such interruptions will not affect the quality of the training, as the state of the training is saved periodically. This design ensures flexibility and control of the training, allowing the researcher to make necessary adjustments during the training process to obtain optimal results.

After starting training, scroll up. The preview area on the right allows us to monitor the training process and progress.

text inversion training setting 3

At first it may not look much like Angelina. Later on it will look more and more like Angelina. The preview image may not look very good, and sometimes there are chipped hands and feet. This is because it’s generated using a base model, and the prompt doesn’t have quality boosting words in it, like “best quality”, etc. There’s also no negative prompt to diminish things like “best quality”. There are no negative prompts to minimize problems such as broken hands and feet. When we use the trained embedding and other models, such as realistic vision, to generate Angelina’s image, the results will be much better. When we pause the training, or when the training has finished, we can check the effect of the generated embedding.Stable Diffusion will place the training data by date in the ‘text_inversion’ folder.

The date folder organizes the files by the name of the embedding. The trained embedding is placed in this ’embeddings’ folder. I’ve set it to generate one embedding every N steps, so here you can see that many embeddings have been generated, and the number in the name of these embeddings represents the number of steps. I’m using a server here, so the format is not quite the same as on a local computer, but the folder structure is the same.


With so many embedding, how do we know which one works best? You can copy the test embedding to the embeddings folder in the A1111 root directory. Then, you can generate a comparison chart of these embeddings in A1111 to compare their actual effects.

In fact, I’ve already shown a couple of comparison charts that were generated using the method I’m about to describe.
