Artificial Intelligence 08 | Exact Inference through variable Elimination | DA | GATE Crash Course

Strengthen your Artificial Intelligence preparation for GATE DA with this focused session on Exact Inference through Variable Elimination, a core topic in probabilistic reasoning and Bayesian Networks. In this lecture, we explain the concept of exact inference, factor representation, variable elimination steps, ordering of variables, and computational complexity with clear examples. You will learn how probability queries are efficiently solved using factor multiplication and marginalization, along with insights into why variable elimination is preferred over brute-force methods. This session is fully aligned with the GATE AI syllabus and helps you confidently tackle PYQs and conceptual questions from probabilistic models. 📕 𝐁𝐚𝐭𝐜𝐡/𝐂𝐨𝐮𝐫𝐬𝐞 𝐋𝐢𝐧𝐤𝐬:- Mission 100 GATE CSE 2026 Batch Link - https://www.geeksforgeeks.org/courses/mission-100-gate-cse-2026 Mission 100 GATE CSE 2026 Batch Link - https://www.geeksforgeeks.org/courses/mission-100-gate-da-2026 GATE GURUKUL Course Link - https://www.geeksforgeeks.org/courses/gate-premium All courses - https://www.geeksforgeeks.org/courses/category/gate?utm_source=youtube&utm_medium=livestreams&utm_campaign=gatelivesessions GATE 2026 CS & IT Test Series Link - https://www.geeksforgeeks.org/courses/gate-cse-it-test-series-2026 GATE 2026 DA Test Series Link - https://www.geeksforgeeks.org/courses/gate-da-testseries-2026 GATE CSE Weekday / Weekend (2027) - https://www.geeksforgeeks.org/courses/category/gate#cse (2028) - https://www.geeksforgeeks.org/courses/category/gate#cse (2029) - https://www.geeksforgeeks.org/courses/category/gate#cse GATE DA Weekday / Weekend (2027) - https://www.geeksforgeeks.org/courses/category/gate#da (2028) - https://www.geeksforgeeks.org/courses/category/gate#da ( 2029 ) - https://www.geeksforgeeks.org/courses/category/gate#da GATE Combo CS / DA Weekday / Weekend ( 2027 ) - https://www.geeksforgeeks.org/courses/category/gate#csit-da ( 2028 ) - https://www.geeksforgeeks.org/courses/category/gate#csit-da ( 2029 ) - https://www.geeksforgeeks.org/courses/category/gate#csit-da GATE CSIT With Placement Preparation Complete Course (2027) - https://www.geeksforgeeks.org/courses/gate-2027-placement-csit?utm_source=youtube&utm_medium=livestreams&utm_campaign=gatelivesessions (2028) - https://www.geeksforgeeks.org/courses/gate-2028-placement-csit?utm_source=youtube&utm_medium=livestreams&utm_campaign=gatelivesessions GATE SPL.
