3 main types of memory used in AI systems. I’ve explained it in a simple way below. 1. 𝗘𝗽𝗶𝘀𝗼𝗱𝗶𝗰 𝗠𝗲𝗺𝗼𝗿𝘆 Episodic Memory is about 𝗿𝗲𝗺𝗲𝗺𝗯𝗲𝗿𝗶𝗻𝗴 𝗽𝗮𝘀𝘁 𝗶𝗻𝘁𝗲𝗿𝗮𝗰𝘁𝗶𝗼𝗻𝘀 𝗮𝗻𝗱 𝗲𝘅𝗽𝗲𝗿𝗶𝗲𝗻𝗰𝗲𝘀. • 𝗡𝗼𝘁𝗶𝗰𝗲 𝗲𝘃𝗲𝗻𝘁: Detect when a new interaction happens (Eg: A user sends a message) • 𝗖𝗼𝗹𝗹𝗲𝗰𝘁 𝗰𝗼𝗻𝘁𝗲𝘅𝘁: Capture details like time, user, and situation • 𝗥𝗲𝗰𝗼𝗿𝗱 𝗮𝗰𝘁𝗶𝗼𝗻: Save what the AI did in response • 𝗦𝗮𝘃𝗲 𝗼𝘂𝘁𝗰𝗼𝗺𝗲: Store the result of the interaction • 𝗖𝗿𝗲𝗮𝘁𝗲 𝗿𝗲𝗰𝗼𝗿𝗱: Turn the event into a memory entry • 𝗥𝗲𝘁𝗿𝗶𝗲𝘃𝗲 𝗿𝗲𝗰𝗼𝗿𝗱𝘀: Pull past memories when needed • 𝗖𝗼𝗺𝗽𝗮𝗿𝗲 𝗵𝗶𝘀𝘁𝗼𝗿𝘆: Match new requests with past events • 𝗢𝗿𝗴𝗮𝗻𝗶𝘇𝗲 𝗱𝗮𝘁𝗮: Structure memories for easy access • 𝗦𝘁𝘂𝗱𝘆 𝗽𝗮𝘁𝘁𝗲𝗿𝗻𝘀: Detect repeated behaviors • 𝗚𝘂𝗶𝗱𝗲 𝗱𝗲𝗰𝗶𝘀𝗶𝗼𝗻: Use past experience to improve responses • 𝗟𝗼𝗴 𝗻𝗲𝘄 𝗿𝗲𝗰𝗼𝗿𝗱: Store the latest interaction • 𝗘𝘅𝗽𝗮𝗻𝗱 𝗺𝗲𝗺𝗼𝗿𝘆: Continuously grow memory over time ____________________ 2. 𝗦𝗲𝗺𝗮𝗻𝘁𝗶𝗰 𝗠𝗲𝗺𝗼𝗿𝘆 Semantic Memory is about 𝗸𝗻𝗼𝘄𝗹𝗲𝗱𝗴𝗲, 𝗳𝗮𝗰𝘁𝘀, 𝗮𝗻𝗱 𝘂𝗻𝗱𝗲𝗿𝘀𝘁𝗮𝗻𝗱𝗶𝗻𝗴. • 𝗚𝗲𝘁 𝗾𝘂𝗲𝗿𝘆: Receive the user’s question • 𝗜𝗱𝗲𝗻𝘁𝗶𝗳𝘆 𝗶𝗻𝘁𝗲𝗻𝘁: Understand what the user really means • 𝗦𝗲𝗮𝗿𝗰𝗵 𝗸𝗻𝗼𝘄𝗹𝗲𝗱𝗴𝗲: Look for relevant information • 𝗟𝗶𝗻𝗸 𝗰𝗼𝗻𝗰𝗲𝗽𝘁𝘀: Connect related ideas together • 𝗣𝘂𝗹𝗹 𝗳𝗮𝗰𝘁𝘀: Gather accurate information • 𝗖𝗼𝗹𝗹𝗲𝗰𝘁 𝗿𝗲𝗹𝗮𝘁𝗶𝗼𝗻𝘀: Add supporting context • 𝗙𝗼𝗿𝗺𝗮𝘁 𝗿𝗲𝗽𝗹𝘆: Structure the response clearly • 𝗥𝗲𝗳𝗲𝗿𝗲𝗻𝗰𝗲 𝘀𝗼𝘂𝗿𝗰𝗲𝘀: Use supporting knowledge if needed • 𝗦𝗲𝗻𝗱 𝗼𝘂𝘁𝗽𝘂𝘁: Deliver the final answer • 𝗠𝗮𝗿𝗸 𝗳𝗶𝘅𝗲𝘀: Learn from corrections • 𝗨𝗽𝗱𝗮𝘁𝗲 𝗸𝗻𝗼𝘄𝗹𝗲𝗱𝗴𝗲: Improve knowledge over time ____________________ 3. 𝗣𝗿𝗼𝗰𝗲𝗱𝘂𝗿𝗮𝗹 𝗠𝗲𝗺𝗼𝗿𝘆 Procedural Memory is about 𝗵𝗼𝘄 𝗔𝗜 𝗽𝗲𝗿𝗳𝗼𝗿𝗺𝘀 𝘁𝗮𝘀𝗸𝘀 𝗮𝗻𝗱 𝘄𝗼𝗿𝗸𝗳𝗹𝗼𝘄𝘀. • 𝗚𝗲𝘁 𝘁𝗮𝘀𝗸: Receive a task to complete (Eg: Write an email) • 𝗜𝗱𝗲𝗻𝘁𝗶𝗳𝘆 𝘁𝘆𝗽𝗲: Understand the type of task • 𝗠𝗮𝘁𝗰𝗵 𝘁𝗼 𝗳𝗹𝗼𝘄: Select the correct workflow • 𝗟𝗼𝗮𝗱 𝗽𝗿𝗼𝗰𝗲𝘀𝘀: Prepare step-by-step instructions • 𝗔𝗱𝗱 𝗶𝗻𝗽𝘂𝘁𝘀: Use user data and parameters • 𝗘𝘅𝗲𝗰𝘂𝘁𝗲 𝘀𝘁𝗲𝗽𝘀: Perform actions one by one • 𝗦𝗮𝘃𝗲 𝗽𝗿𝗼𝗴𝗿𝗲𝘀𝘀: Track progress during execution • 𝗟𝗼𝗴 𝗼𝘂𝘁𝗰𝗼𝗺𝗲: Record results of the task • 𝗦𝗲𝗻𝗱 𝗿𝗲𝘀𝘂𝗹𝘁: Deliver final output • 𝗛𝗮𝗻𝗱𝗹𝗲 𝗰𝗼𝗻𝗱𝗶𝘁𝗶𝗼𝗻𝘀: Manage errors or special cases • 𝗖𝗼𝗻𝘁𝗶𝗻𝘂𝗲 𝗽𝗿𝗼𝗰𝗲𝘀𝘀: Improve workflow for next time ✅ 𝗜𝗻 𝗦𝗵𝗼𝗿𝘁: • Episodic → remembers events & experiences • Semantic → understands knowledge & meaning • Procedural → knows how to perform tasks Very important for people to understand who are building AI systems and processes. ✅ Repost for others so they can understand different memory types in AI.
