HSVI

One-Liner

“impact of approximation decreases as steps from the root node”

Novelty

• combined alpha-vector and forward heuristics to guide search of belief states before backup
• 100x times faster in PBVI
• scales to huge environments

Goal: minimize “regret” (difference until optimal policy)

Novelty HSVI 2

• Projected the upper bound onto a convex hull (HSVI2: via approximate convex hull projection)
• uses blind lower bound

Social Learning is the property of learning with other agents in your environment.

• learning from feedback
• human ai coordination
• social learning
• adversarial training

A Social Network is a scheme for studying the relationships and interactions amongst groups of people.

• people: \(V\)
• relationship: \(E\)
• system: a network \(G(V,E)\)

Importantly, the “labels” of \(E\) often do not matter as we frequently want to study only the graphical structure of the Social Network.

degree (node)

The degree of a node is the number of edges that are touching that node (whether in or out, or undirected).

The in-degree and out-degree are the number of edges touching that node (going in or out) respectively.
