Atlas: Joint Retriever-Reader Pre-Training Beats 540B-Parameter LLMs with 11B Parameters
Atlas (JMLR 2023) achieves 42.4% accuracy on Natural Questions with only 64 training examples—beating PaLM 540B by 3 points using 11B parameters—by jointly pre-training a Contriever-based dense retriever with a T5 Fusion-in-Decoder reader. Analysis covers retrieval accuracy limits, 587GB index infrastructure costs, and implications for Beancount ledger QA systems.
LLMs Are Not Useful for Time Series Forecasting: What NeurIPS 2024 Means for Finance AI
A NeurIPS 2024 Spotlight paper ablates three LLM-based time series forecasting methods — OneFitsAll, Time-LLM, and CALF — and finds that removing the language model improves accuracy in most cases, with up to a 1,383× training speedup. For finance AI applications like Beancount balance prediction, lightweight purpose-built models consistently beat repurposed LLMs.
TAT-LLM: Ge-fined-tunde LLaMA 2 voor discreet redeneren over financiële tabellen en tekst
TAT-LLM fine-tunt LLaMA 2 7B met LoRA op financiële tabel-tekst QA-benchmarks en behaalt 64,60% EM op FinQA — waarmee het de 63,91% van GPT-4 verslaat — door redenering te ontleden in deterministische Extraheer-Redeneer-Voer-uit stappen die rekenkundige fouten elimineren.
IRCoT: Interleaving Retrieval with Chain-of-Thought for Multi-Step QA
IRCoT interleaves BM25 retrieval with each step of a chain-of-thought reasoning loop, achieving +11.3 retrieval recall and +7.1 F1 on HotpotQA over one-step RAG — and shows a 3B model can beat GPT-3 175B when retrieval strategy is right.
FLARE: Active Retrieval Augmented Generation
FLARE (EMNLP 2023) improves on standard RAG by triggering retrieval mid-generation using token-probability confidence thresholds, reaching 51.0 EM on 2WikiMultihopQA versus 39.4 for single-retrieval — but calibration failures in instruction-tuned chat models limit its reliability for production finance agents.
MultiHiertt: Benchmarking Numerical Reasoning Over Multi-Hierarchical Financial Tables
MultiHiertt (ACL 2022) introduces 10,440 QA pairs from real financial reports averaging 3.89 hierarchical tables each; state-of-the-art models score 38% F1 versus 87% for humans, with a 15-point penalty for cross-table questions — quantifying the retrieval gap finance AI must close.
ConvFinQA: Multi-Turn Financial QA and the 21-Point Gap Between Models and Human Experts
ConvFinQA (EMNLP 2022) extends FinQA into multi-turn conversation over S&P 500 earnings reports, finding that the best fine-tuned model achieves 68.9% execution accuracy versus 89.4% for human experts—and drops to 52.4% on hybrid multi-aspect conversations where models must carry numerical context across different financial topics.
TAT-QA: Hybrid Table-Text QA Benchmark for Financial Annual Report Reasoning
TAT-QA is a 16,552-question benchmark over hybrid table-plus-text financial report contexts that showed evidence grounding — not arithmetic — is the core bottleneck in finance AI; by 2024, fine-tuned 7B LLMs reached 83% F1, closing most of the gap against a 91% human ceiling.
FinQA: The Benchmark Measuring AI Numerical Reasoning on Financial Reports
FinQA (EMNLP 2021) built 8,281 QA pairs from S&P 500 earnings reports requiring multi-step arithmetic programs. Neural models scored 61% at release versus 91% for human experts; accuracy collapses to 22% on three-or-more-step programs. The failure modes — domain constants, cross-modality grounding, chain length — map directly to the challenges Beancount agents face today.
DSPy: Replacing Brittle Prompt Engineering with Compiled LLM Pipelines
DSPy replaces hand-crafted prompt strings with declarative signatures and a metric-driven compiler—boosting Llama2-13b from 9.4% to 46.9% on GSM8K math reasoning and offering a more maintainable path for production finance AI pipelines.
Self-RAG: Adaptive Retrieval and Self-Critique for LLMs
Self-RAG (ICLR 2024 Oral) trains a language model to decide when to retrieve and then grade its own results using four reflection tokens — reaching 55.8% on PopQA and 80.2 FactScore on biographies while outperforming ChatGPT on five benchmarks. Analysis covers the mechanism, ablation results, reproducibility limits, and implications for finance AI agents over Beancount ledgers.
HippoRAG: Neurobiologically Inspired Long-Term Memory for LLMs
HippoRAG (NeurIPS 2024) builds a knowledge graph from OpenIE triples and applies Personalized PageRank at query time, reaching 89.1% Recall@5 on 2WikiMultiHopQA versus 68.2% for ColBERTv2—with direct implications for querying complex financial ledgers across multi-year transaction histories.
