Tutorial J	Demystifying Machine Learning and Artificial Intelligence: From unsupervised learning through deep learning, explainable AI and ChatGPT
Fees	$250 USD each
Date	Monday – February 26, 2024
Time	1:00 PM – 4:30 PM PT
Overview	Last year’s GSAW tutorial on Demystifying Machine Learning was very well received. The students were engaged and very interested in the topics and methodology covered. We presented details on applications of Machine Learning and Deep Learning and the students were clearly interested in learning more about this subject since they are beginning to encounter it regularly in their work. This year, we plan to expound on these topics and present more information on the different aspects of Machine Learning, especially Deep Learning, Neural Networks and Explainable AI, which is becoming more popular but equally misunderstood. We have found that there is a lot of misconceptions surrounding these topics so we want to further demystify it for folks that are new to the field as well as for those who may have explored areas of these technologies. The determination of features in the data is critically important to successfully building a model, and we present ways to determine the most useful features and how to measure the performance and accuracy of the chosen approaches. Machine Learning, Deep Learning and Artificial Intelligence are all hot topics due to their potential to extract actionable information from the data. However, biases in the data can lead to incorrect models and results, so we present ways to be aware of these potential problems and how to mitigate them. With the need to build trust in the results of an AI model, we spend time on how to implement Explainable AI to understand the results of the models.

She has led CRADs/IRADs in cognitive systems and machine learning/AI. She received her B.S, M.S, and Ph.D. all in Electrical Engineering from Rensselaer Polytechnic Institute.
Description of Intended Audience and Recommended Prerequisites	Tutorial is designed for a non-technical as well as a technical audience. Tutorial is for those interested in learning more about different aspects of Machine Learning and Artificial intelligence, especially as it can apply to ground system and satellite applications. Students should have a desire to learn the details of how Artificial Intelligence can be implemented for data exploitation and the benefits and pitfalls of the different approaches. This year there will be an added emphasis on how to build trust in the models. No prerequisites are needed.
