A cooking video followed by a travel vlog tells a different story than the same two clips in reverse. That ordering is exactly the signal that sequential recommenders are built to exploit.</p> <p>Compare two friends recommending shows. The first knows your favourite genres but never asks what you watched last week. The second says, <em>&ldquo;You just finished three sci-fi thrillers in a row — try this one.&rdquo;</em> Traditional collaborative filtering is friend one. Sequential recommendation is friend two.</p>
