 # Model Card for LoRI-D_code_llama3_rank_64
 
 This model is part of [LoRI: Reducing Cross-Task Interference in Multi-Task Low-Rank Adaptation](https://arxiv.org/abs/2504.07448).
 
-<!-- Provide a quick summary of what the model is/does. -->
-
+**LoRI** (LoRA with Reduced Interference) is a simple yet effective approach that freezes the projection matrices $A$ as random projections and sparsifies the matrices $B$ using task-specific masks. This design substantially reduces the number of trainable parameters while maintaining strong task performance. Moreover, LoRI minimizes cross-task interference in adapter merging by leveraging the orthogonality between adapter subspaces, and supports continual learning by using sparsity to mitigate catastrophic forgetting.

+LoRI-D_code_llama3_rank_64 is an adapter for the `meta-llama/Meta-Llama-3-8B` base model, fine-tuned using the LoRI (LoRA with Reduced Interference) framework specifically for code generation tasks. LoRI is a parameter-efficient fine-tuning (PEFT) method designed to address overhead and parameter interference in multi-task scenarios when using traditional LoRA. It achieves this by freezing projection matrices `A` as random projections and sparsifying matrices `B` with task-specific masks, significantly reducing trainable parameters while maintaining strong performance. This model utilizes a rank of 64 for its LoRA adaptations.

-
 ### Direct Use
 
-<!-- This section is for the model use without fine-tuning or plugging into a larger ecosystem/app. -->
-
-[More Information Needed]
-
-### Downstream Use [optional]
+This model is intended to be loaded as a PEFT adapter on top of the `meta-llama/Meta-Llama-3-8B` base model to enhance its performance on code generation tasks. It provides an efficient way to fine-tune large language models with significantly fewer trainable parameters.
 
-<!-- This section is for the model use when fine-tuned for a task, or when plugged into a larger ecosystem/app -->
+### Downstream Use
 
-[More Information Needed]
+LoRI adapters facilitate effective adapter merging and continual learning across various tasks, including natural language understanding, mathematical reasoning, code generation, and safety alignment. This makes them suitable for multi-task learning environments and adaptive model deployments.
 
 ### Out-of-Scope Use
 
-<!-- This section addresses misuse, malicious use, and uses that the model will not work well for. -->
-
-[More Information Needed]
+This model is not intended for generating harmful, biased, or unethical content. Users should exercise caution and implement appropriate safeguards when deploying it in real-world applications, especially in sensitive domains.
 
 ## Bias, Risks, and Limitations
 
-<!-- This section is meant to convey both technical and sociotechnical limitations. -->
-
-[More Information Needed]
+As an adaptation method built upon pre-trained Large Language Models, LoRI models inherit biases and risks present in their base models (e.g., Meta-Llama-3-8B) and the datasets they were fine-tuned on. Users should be aware of potential issues related to fairness, toxicity, and factual accuracy. Specific limitations include:
+-   Performance might vary depending on the chosen base model and the sparsity level.
+-   While LoRI significantly reduces cross-task interference, perfect isolation of knowledge across tasks is not guaranteed during adapter merging.
 
 ### Recommendations
 
-<!-- This section is meant to convey recommendations with respect to the bias, risk, and technical limitations. -->
-
-Users (both direct and downstream) should be made aware of the risks, biases and limitations of the model. More information needed for further recommendations.
+Users (both direct and downstream) should refer to the original `meta-llama/Meta-Llama-3-8B` model card for inherent biases and risks. It is recommended to perform task-specific evaluations and careful validation when deploying models fine-tuned with LoRI in sensitive applications.

+### Training Procedure
 
-#### Speeds, Sizes, Times [optional]
+LoRI is implemented using Fully Sharded Data Parallel (FSDP) and supports multi-GPU training environments. The training process involves two main stages:

+2.  **LoRI-S (Sparsity):** Continued training with the learned sparse masks (e.g., 90% sparsity) applied to matrices `B`, further reducing parameters and promoting orthogonality.

+Extensive experiments demonstrated that LoRI outperforms full fine-tuning and existing PEFT methods while using up to 95% fewer trainable parameters than standard LoRA. For code generation, performance was evaluated on the HumanEval benchmark. In multi-task experiments, LoRI enabled effective adapter merging and continual learning with reduced cross-task interference. Detailed evaluation results and comparisons can be found in the accompanying paper.
