Welcome students! Today, weβre starting with the concept of bias in machine learning. Can anyone explain what we mean by bias?
Bias refers to systematic prejudice that can lead to unfair outcomes in AI systems.
Exactly! Bias often reflects societal inequalities. Now, can anyone name some sources of bias in ML?
Historical bias from data is one source.
Also, measurement bias from how data is collected can distort results.
Great points! Remember the acronym HAIL: Historical, Algorithmic, Interpretative, and Labeling bias. Each of these can affect our models significantly.
What about ways to detect bias?
Good question! Techniques like disparate impact analysis can help. Can anyone explain what that involves?
It compares model outputs across different demographic groups.
Right! Let's summarize: weβve learned about bias sources and some detection methodologies. Excellent engagement!

Moving on, let's explore the pillars of ethical AI. Why do you think accountability is essential in AI?
It helps ensure developers are responsible for the outcomes of their systems.
Exactly! And what does transparency entail?
It means making how the AI system works clear to users and stakeholders.
Great! Now, what about privacy? Why is it a critical concern?
To protect individuals' data and avoid misuse or breaches.
Absolutely! Remember the acronym TAP: Transparency, Accountability, Privacy. It's a quick way to recall these important concepts.
What are some strategies to ensure privacy in AI?
Techniques like differential privacy and federated learning are important! In conclusion, these principles need to be interwoven throughout the AI project lifecycle.
Explainable AI (XAI)

Now let's discuss Explainable AI, or XAI. Who can tell me why XAI is necessary?
It helps users understand how AI models make decisions.
Exactly! Can anyone name a method used in XAI?
LIME is one. It explains predictions by approximating a local model.
That's correct! And what about SHAP?
SHAP assigns an importance value to each feature to explain its impact on predictions.
Well done, everyone! To remember these techniques, think of the story of two friends: LIME focuses on specific situations, while SHAP gives a broader view across many situations.
What should we keep in mind while implementing these techniques?
Always ensure that the explanations don't oversimplify complex models. Excellent participation today, everyone!
