T-719-NXAI-2025 READINGS
Make sure to read the required number of papers (first number inside the brackets - the second one is the “minimum recommended”) and make sure to not fall behind on readings (I assign you only a few papers per day for a good reason - so you can get through them in time for the discussion session on that day). Note: We will interweave content from prior sessions in the following ones, so if you fall behind two or more days in a row, you will be significantly challenged to keep up (there are subtleties in the content that is really key to understanding the content and passing the course - you may feel like you're following along the discussion, but there will likely be important things you're missing).
Guidelines for how to read in this course (seriously! - do not skip).

Readings README
Note: DO NOT SKIP READING THE BELOW TEXT
As you read papers from each of the following categories I want you ask yourself a few questions:
- For each paper in each category X, ask yourself:
- What is X?
- How does the human mind do X?
- Do current computers do X?
- …and …
- Do we need (to replicate or capture) what the human mind does to achieve X to create a machine that rivals the ability of humans to do X?
If you can answer them satisfactorily when you're done reading you're good! Even if you can't you'll be fine if you: Write down the discrepancies and bring them to class in the form of questions. There is no such thing as a 'stupid question' when you're learning something new!
