Manifold UserModeling Benchmark (Belief WIP)

This repository mirrors the Polymarket benchmark layout and currently focuses on Belief-layer data preparation.

Folder Layout

  • dataset/Belief/source/
  • dataset/Belief/splits/
  • dataset/Belief/support_set/
  • benchmark/Belief/{direct,profile,retrieval}/ (placeholders for next stage)
  • metadata/

1) Source Tables (dataset/Belief/source/)

data.csv

User-market final belief master table (one row per userId*marketId).

Key columns:

  • userId, marketId
  • options_n
  • dominant_option, dominant_net, dominant_share
  • candidate_options_json
  • candidate_net_json
  • candidate_bets_json

Use this table as the primary supervised target source for Belief tasks.

option_accumulate.csv

Candidate-level accumulate table (one row per userId*marketId*option).

Key columns:

  • option_key (ANS:<answerId> for multi-choice, SIDE:YES/NO for binary-like)
  • accumulate_net_amount
  • bets_count

Use this when you need per-candidate decomposition rather than only the dominant option.


2) Query Splits (dataset/Belief/splits/)

train.csv, validation.csv, test.csv

Rows are query userId*marketId samples split by per-user market last-bet time chronology.

split_summary.txt

Split counts summary.

wallet_ids_experiment_2000.csv

The sampled query user pool (2000 users, bucketed by markets_per_user).


3) Support Set (dataset/Belief/support_set/)

support_users.csv

Support user list and user-level stats.

support_belief_final.csv

Support users' final user*market belief summary (dominant/candidate aggregate view).

support_belief_option_accumulate.csv

Support users' candidate-level accumulate records.

support_user_bets_chrono.csv

Support users' deduplicated bet events, sorted by:

  1. userId
  2. createdTime
  3. betId

Key columns include:

  • userId, createdTime, betId, marketId
  • outcome, answerId, amount, shares
  • probBefore, probAfter, isApi

support_user_bets_index.csv

Per-user row-range index into support_user_bets_chrono.csv for fast retrieval.

Columns:

  • userId
  • start_row_in_events_csv_1based_excluding_header
  • end_row_in_events_csv_1based_excluding_header
  • num_bets

How to Use (Current Stage)

Belief supervised training

  • Use dataset/Belief/splits/{train,validation,test}.csv as query samples.
  • Use dominant_option (or candidate distribution fields) from source as labels.

Retrieval-style setup

  • Query side: split files (train/val/test).
  • Support side:
    • User-level belief memory: support_belief_final.csv
    • Event-level memory: support_user_bets_chrono.csv + support_user_bets_index.csv

Notes

  • Current files are CSV for transparency and easier inspection.
  • Next stage will generate benchmark/Belief/direct, profile, and retrieval artifacts aligned with Polymarket format.
