Train and serve learning over graphs

Follow graph representation, neighborhood sampling, message passing, partitions, and update paths while testing leakage and stale-neighbor effects.

  1. 01

    Store graph neighborhoods with explicit CSR and CSC orientation

    Connect pointer arrays, edge multiplicity, degree counts and feature access patterns.

    24 min
  2. 02

    Budget sampled neighborhoods without losing estimator semantics

    Track occurrence growth, unique nodes and probability weights separately.

    24 min
  3. 03

    Specify message direction, normalization and nonlinear placement

    Distinguish sums, means, GCN normalization and attention rather than treating them as interchangeable averages.

    24 min
  4. 04

    Compact minibatches while preserving global node identity

    Share feature rows without accidentally merging messages, layers or time contexts.

    24 min
  5. 05

    Balance partitions using the communication the model actually performs

    Relate edge cuts, boundary-node reuse and per-layer traffic under explicit assumptions.

    24 min
  6. 06

    Own, cache and update distributed embedding rows explicitly

    Separate trainable ID tables from feature-based embedding generation and account for optimizer state.

    24 min
  7. 07

    Build graph state from information available at prediction time

    Separate event time, arrival time, tie policy and state-update order.

    24 min
  8. 08

    Define what a negative edge means before sampling it

    Control false negatives, information boundaries and candidate distributions in link prediction.

    24 min
  9. 09

    Serve graph features and representations with a coherent freshness policy

    Trace dependencies, stale publications and model-compatible cache versions.

    24 min
  10. 10

    Match graph evaluation splits to the claimed generalization

    Separate transductive visibility, unseen-node encoding and temporal prediction protocols.
