Mitigating AI Risks

• AI provides benefits (innovation, efficiency) but also introduces risks

Main Risks:

• Lack of transparency → AI decisions are difficult to understand

• Bias and harmful outcomes → unfair decisions, privacy issues

Risk Mitigation:

• Governance frameworks → establish rules and policies for AI use

• Transparency → ensure AI systems are explainable

• Human oversight → humans monitor and guide AI decisions

Responsible AI:

• Approach to building AI that is safe, ethical, and trustworthy

• Focus on:

  • Fairness

  • Reliability

  • Transparency

• Keep people at the center of design and decision-making

Microsoft and GitHub’s Six Principles of Responsible AI

• Six principles guide responsible AI development and use

Principles:

1. Fairness

   • AI should treat all people equally

   • Avoid bias and unfair outcomes

   • Use balanced data and test across different groups

2. Reliability and Safety

   • AI must work consistently and as expected

   • Handle unexpected situations safely

   • Minimize physical, emotional, and financial harm

3. Privacy and Security

   • Protect user data and ensure confidentiality

   • Collect only necessary data with user consent

   • Use anonymization and encryption

   • Restrict and monitor access to sensitive data

4. Inclusiveness

   • AI should be accessible and usable by everyone

   • Work across diverse populations and regions

   • Support people with disabilities and different languages

   • Ensure no group is excluded

5. Transparency

   • AI systems should be understandable and explainable

   • Clearly communicate how they work and their limitations

   • Enable auditing, logging, and monitoring

6. Accountability

   • Humans are responsible for AI systems

   • Monitor performance and manage risks

   • Organizations must take ownership of AI outcomes
