“New tools and skills are needed to help organisations identify these and other potential sources of bias, build more trust in using AI models, and reduce corporate brand and reputation risk,” saidJim Hare, research vice president at Gartner. “More and more data and analytics leaders and chief data officers (CDOs) are hiring ML forensic and ethics investigators.”
Increasingly, sectors like finance and technology are deploying combinations of AI governance and risk management tools and techniques to manage reputation and security risks. In addition, organizations such as Facebook, Google, Bank of America, MassMutual and NASA are hiring or have already appointed AI behaviour forensic specialists who primarily focus on uncovering undesired bias in AI models before they are deployed.
These specialists are validating models during the development phase and continue to monitor them once they are released into production, as unexpected bias can be introduced because of the divergence between training and real-world data.
“While the number of organisations hiring ML forensic and ethics investigators remains small today, that number will accelerate in the next five years,” added Mr Hare.
On one hand, consulting service providers will launch new services to audit and certify that the ML models are explainable and meet specific standards before models are moved into production. On the other, open-source and commercial toolsspecifically designed to help ML investigators identify and reduce bias are emerging.
Some organisations have launched dedicated AI explainability tools to help their customers identify and fix bias in AI algorithms. Commercial AI and ML platform vendors are adding capabilities to automatically generate model explanations in natural language. There are also open-source technologies such as Local Interpretable Model-Agnostic Explanations (LIME) that can look for unintended discrimination before it gets baked into models.
These and other tools can help ML investigators examine the “data influence” of sensitive variables — such as age, gender or race — on other variables in a model. “They can measure how much of a correlation the variables have with each other to see whether they are skewing the model and its outcomes,” said Mr Hare.Data and analytics leaders and CDOs are not immune to issues related to lack of governance and AI missteps. “They must make ethics and governance part of AI initiatives and build a culture of responsible use, trust and transparency. Promoting diversity in AI teams, data and algorithms, and promoting people skills is a great start,” said Mr Hare. “Data and analytics leaders must also establish accountability for determining and implementing the levels of trust and transparency of data, algorithms and output for each use case. It is necessary that they include an assessment of AI explainability features when assessing analytics, business intelligence, data science and ML platforms.”
