Data Sets and Their Role in AI: Data sets play a crucial role in AI by defining problems and providing fuel for algorithms. In the business world, data sets are tools used to meet customer needs, especially human-centered ones. Unintended consequences, such as bias, may arise from data sets, so it’s essential to mitigate these issues.
Mitigating Bias in AI: Raising awareness about the unintended consequences of technology, particularly bias in data and algorithms, is crucial. Embedding ethics education into computer science curricula to create a generation of tech-savvy and ethically-minded technologists. Investing in algorithm and data development technologies to de-bias or avoid bias. Advocating for interdisciplinary inclusion of ethicists and philosophers in algorithm design. Establishing governance mechanisms for data and algorithm oversight, including legal and policy frameworks.
North Stars in AI Research: AI research has become diverse and offers many opportunities, making it challenging to identify specific North Stars. Large language models in natural language processing have made remarkable progress, highlighting the field’s dynamism. Embodied intelligence and immersion in the visual world are becoming increasingly important areas of research in computer vision. Understanding intelligence as a tool for survival, seeking food, avoiding predators, communicating, and socializing is crucial for advancing AI research.
00:28:37 Embodied Intelligence and Dynamic Human-Algorithm Learning
Fei-Fei Li’s Research Interests: Transition from passive visual intelligence to an embodied and active approach. Excited by the interaction between robotics and vision.
