1. Latitude
Latitude is an open-source platform designed to bring domain experts and engineers together to tackle bias in AI systems. Instead of separating technical teams from subject matter experts, it provides a collaborative space where both can work side by side, ensuring a more integrated approach to bias reduction.
Collaboration Capabilities
Latitude shines in fostering teamwork across developers, product managers, and domain experts. Why is this crucial? Because domain experts often have the contextual knowledge needed to spot subtle biases that technical teams might miss. By combining these perspectives, the platform helps create more balanced and fair AI systems.
Its Prompt Manager and Playground allow real-time collaboration, where experts and engineers can design, test, and refine prompts together. The platform supports advanced features like variables, conditionals, and loops through PromptL, giving domain experts the tools to work directly with prompts while engineers handle the technical complexities in the background.
Latitude also plays a key role in auditing datasets to identify gaps and ensure diversity. For industries like hiring or finance, where biases can have serious consequences, this process helps reduce risks and improve fairness. The platform’s shared communication and project management tools further streamline collaboration, making it easier for teams to stay aligned.
Bias Mitigation Effectiveness
Latitude’s approach to bias mitigation is rooted in thorough evaluation and monitoring. Its Evaluations feature helps teams measure prompt performance using a mix of methods: LLM-as-judge techniques, programmatic rules, and human review. By tracking performance metrics, teams can quickly identify and address potential issues. Automated logs also provide an audit trail, which is essential for maintaining quality and accountability.
Considering that 40% of consumers believe companies using generative AI aren’t doing enough to protect against bias and misinformation, Latitude’s structured approach offers organizations a way to build trust. Its evaluation tools and monitoring systems scale seamlessly as language models grow more complex, ensuring that bias detection remains effective.
Scalability and Maintenance
As language models become more intricate and data sources expand, Latitude is built to scale with these challenges. The platform offers a full lifecycle management system for prompts, ensuring bias reduction strategies evolve alongside the models. Its Datasets feature helps teams manage test data for batch evaluations and regression testing, making it easier to ensure that previously fixed biases don’t resurface.
Latitude also emphasizes structured, automated testing, which is key to efficient deployments. Manual checks become less practical as applications grow in size and complexity, so automation helps maintain bias reduction without slowing down progress. And since Latitude is open-source, it encourages a community-driven exchange of techniques, enabling teams to share and refine strategies for promoting fairness across AI systems.
2. Expert-Led Data Curation
Expert-led data curation offers a hands-on approach to reducing bias in AI systems, building on the collaborative framework established by Latitude. Unlike automated methods, this strategy relies on domain specialists to carefully select and refine training data for large language models (LLMs). By leveraging human expertise, it helps identify subtle biases and ensures a more inclusive representation of diverse groups and contexts.
Jason Corso, Professor of Robotics, Electrical Engineering, and Computer Science at the University of Michigan and Co-Founder/Chief Science Officer of Voxel51, highlights the importance of data in AI development:
"For a given problem, you can choose any one of N model architectures off the shelf, but your ultimate performance is going to come from the data you marry with that model architecture".
Collaboration Capabilities
Expert-led curation thrives on collaboration between data scientists and domain experts, addressing a critical gap often seen in traditional AI development. Technical teams, while skilled, may lack the contextual knowledge needed to detect biases tied to cultural, demographic, or industry-specific factors.
In this process, experts align data with specific guidelines. Human curators excel in tasks like natural language understanding and contextual analysis, areas where automated systems often fall short. Instead of attempting to harmonize entire datasets at once, teams focus on individual attributes, creating summary representations for each element. This systematic approach ensures that expert insights are applied thoroughly across the dataset, enhancing the detection and correction of biases.
Bias Mitigation Effectiveness
The strength of expert-led curation lies in its ability to address both data and algorithmic bias through meticulous human oversight. A 2024 MIT study auditing 1,800 public text datasets revealed that over 70% lacked proper source documentation, potentially hiding problematic content. Expert curation directly tackles this issue by ensuring transparent annotation processes and conducting regular audits.
Human curators are particularly adept at recognizing context and resolving ambiguities that automated systems might overlook, such as cultural nuances or historical and industry-specific considerations. For instance, an AI lab initially aimed to collect 100,000 human-labeled examples to improve a large language model but fell short of performance benchmarks. A data strategy team stepped in, identifying weaknesses and curating a targeted dataset of just 4,000 examples. This smaller, focused dataset boosted the model's performance by an impressive 97%, using only 4% of the originally planned data volume.
This approach also integrates ethical considerations, ensuring that the curation process accounts for the potential impact of biases on different groups. Regular audits create a continuous improvement loop, something automated systems struggle to replicate.
Scalability and Maintenance
While expert-led curation excels at identifying and mitigating bias, scaling this approach comes with its own set of challenges. As data volumes grow, maintaining quality, ensuring consistent interpretations across experts, and keeping datasets updated become increasingly complex.
To address these challenges, modern implementations often combine human oversight with automated processes. For example, large language models can assist with manual tasks like synonym generation or numeric transformations, but human experts are still needed to validate accuracy. This hybrid approach balances the speed of automation with the precision of human expertise.
Jason Corso emphasizes the importance of continuous refinement:
"The success of any ML/AI project hinges on the effective continuous refinement of both the data and the model".
To scale effectively, teams can break large tasks into smaller, manageable steps. Tools like external APIs or mini-programs can handle repetitive tasks, freeing experts to focus on higher-level analysis. For unstructured text, clear instructions and targeted document preparation help maintain consistency across large datasets.
Ultimately, data curation cannot be fully automated or outsourced because it requires deep domain knowledge and contextual understanding that vary by industry and use case. Organizations can build sustainable expert-led processes by establishing clear guidelines, training domain experts, and creating feedback loops to capture and refine institutional knowledge over time.
This investment in expert-led curation is particularly crucial when considering the high failure rates of AI projects. Gartner estimates that up to 85% of AI projects fail, while the Wall Street Journal suggests the failure rate for generative AI projects may be as high as 90%, often due to unrealistic expectations of data. By prioritizing human expertise in data curation, organizations can significantly improve their chances of developing robust and unbiased AI systems.
