IBM announces cloud service to help businesses detect and mitigate AI bias | Industry
Breaking Tech Industry news from the top sources
Bias is a serious problem in artificial intelligence (AI). Research shows that popular smart speakers are 30 percent less likely to understand non-American accents, for example, and that facial recognition systems such as those from Cognitec perform demonstrably worse on African Americans. In fact, according to a recent study comissioned by IBM, two-thirds of businesses are wary of adopting AI because of the potential liability issues.
In an effort to help enterprises address the problem, IBM today announced the launch of a cloud-based, fully automated service that “continually provides [insights]” into how AI systems are making their decisions. It additionally scans for signs of prejudice and recommends adjustments — such as algorithmic tweaks or counterbalancing data — that might lessen their impact.
The service’s explanations show which factors influenced a given machine learning model’s decision, plus its overall accuracy, performance, fairness, and lineage. In addition, it lays bare the confidence in its bias-mitigating recommendations and any factors contributing to that confidence.
IBM said it works with popular machine learning frameworks and AI build environments, including IBM Watson, Tensorflow, SparkML, AWS SageMaker, and AzureML, and that it can be tailored to individual enterprises’ workflows.
“IBM led the industry in establishing trust and transparency principles for the development of new AI technologies,” David Kenny, SVP of cognitive solutions at IBM, said. “It’s time to translate principles into practice. We are giving new transparency and control to the businesses who use AI and face the most potential risk from any flawed decision making.”
Alongside the announcement, IBM launched in open source a toolkit — the AI Fairness 360 toolkit — containing a library of algorithms, code, and tutorials that demonstrate ways to implement bias detection in models.
IBM’s moves come a month after the publication of a white paper in which several of its researchers proposed “factsheets” for AI systems. The voluntary factsheets — formally called “Supplier’s Declaration of Conformity” (DoC) — would answer questions ranging from system operation and training data to underlying algorithms, test setups and results. More granular topics might include governance strategies used to track the AI service’s data workflow, the methodologies used in testing, and bias mitigations performed on the dataset.
“Like nutrition labels for foods or information sheets for appliances, factsheets for AI services would provide information about the product’s important characteristics,” Aleksandra Mojsilovic, head of AI foundations at IBM Research and codirector of the AI Science for Social Good program, wrote in a blog post introducing the paper. “The issue of trust in AI is top of mind for IBM and many other technology developers and providers. AI-powered systems hold enormous potential to transform the way we live and work but also exhibit some vulnerabilities, such as exposure to bias, lack of explainability, and susceptibility to adversarial attacks. These issues must be addressed in order for AI services to be trusted.”
IBM’s not the only one developing platforms to mitigate algorithmic prejudice. At its F8 developer conference in May, Facebook announced Fairness Flow, an automated bias-catching service for data scientists. Microsoft and Accenture have released similar tools.
