EmbedDrift

S7 class for context-aware differential node embedding analysis between two graphs. Holds both input graphs, their embeddings, the Procrustes-aligned embedding, and the resulting cosine similarity statistics.

Usage

EmbedDrift(graph_dt_1, graph_dt_2)

Arguments

graph_dt_1

A data.frame with columns from, to, and optionally weight representing the first graph.

graph_dt_2

A data.frame with columns from, to, and optionally weight representing the second graph.

Value

An initialised EmbedDrift object.

Properties

graph_dt_1

A data.frame containing the edges of graph 1. Must have columns from, to, and optionally weight.

graph_dt_2

A data.frame containing the edges of graph 2. Must have columns from, to, and optionally weight.

embd_1

Numeric matrix. Node embedding for graph 1, rows are nodes.

embd_2

Numeric matrix. Node embedding for graph 2, rows are nodes.

aligned_embd

Numeric matrix. Procrustes-aligned embedding of graph 1 onto graph 2, restricted to shared nodes.

stats

A data.frame holding per-node cosine similarity scores and node metadata after running the differential analysis.

params

Named list of parameters used during embedding and alignment.
