Revolutionizing Language Models: Overcoming Distraction Issues with Focused Transformers and the Launch of LONGLLAMAs

As Seen On

Advancements in Artificial Intelligence have found incredible use-cases in the realm of language models. However, turning these theories into practical knowledge comes with its own set of challenges. Traditional methods of reinforcing and fine-tuning these models often bump into a wall when it comes to dealing with distractions. Enter the world of Focused Transformers (FOT) that nudge us onto a more promising path.

One of the glaring problems afflicting language models has been the pervasive issue of distraction. With an increasing number of documents, overlaps inevitably occur between keys relating to irrelevant and relevant values. This complicated affair hampers the model’s efficiency, as it begins to lose its primary goal – understanding and interpreting the essence of a language.

The innovative approach of the Focused Transformer aims to tackle this prevalent challenge effectively. This novel method steps into the forefront as an extension to the models’ context length, targeting the distraction issue at its root. The magic of FOT lies in its mechanism that enables a portion of attention layers to tap into an external memory of (key, value) pairs, leveraging the power of the kNN algorithm.

Training FOT models is a game-changer in itself. Drawing inspiration from contrastive learning, the FOT method enhances the language model’s sensitivity to structure. It accomplishes this feat by teaching the model to discriminate between keys attached to different value structures. A rerun of this approach boosts their structural comprehension, leading to a more robust language model.

The most recent manifestation of the FOT technique in action is the fine-tuned OpenLLaMA models known as LONGLLAMAs. These powerhouses are designed explicitly for tasks that rely heavily on extensive context modeling, such as passkey retrieval. As a result, tasks that formerly appeared as challenges are now a quick operation for these models.

As we dwell on the remarkable strides made in this field, some key research contributions stand out. Overcoming the distraction dilemma, the FOT model’s development, and the simple implementation techniques incorporated into the pre-existing models are milestones we owe to these brilliant minds. The outcome of these contributions, like the LONGLLAMAs, have revolutionized tasks that enjoy the benefits of extensive context.

Summarizing the journey thus far, the FOT technique has proved to be a boon for managing the distraction issue and has emerged as a tool to extend context length in language models significantly. The training advancements also underline the importance of extensive context modeling.

Finally, this is just the tip of the iceberg. The complete research paper provides a profound dive into the intricacies of these concepts.

Up until working with Casey, we had only had poor to mediocre experiences outsourcing work to agencies. Casey & the team at CJ&CO are the exception to the rule.

Communication was beyond great, his understanding of our vision was phenomenal, and instead of needing babysitting like the other agencies we worked with, he was not only completely dependable but also gave us sound suggestions on how to get better results, at the risk of us not needing him for the initial job we requested (absolute gem).

This has truly been the first time we worked with someone outside of our business that quickly grasped our vision, and that I could completely forget about and would still deliver above expectations.

I honestly can't wait to work in many more projects together!
