+# TAT-LLM: A Specialized Language Model for Discrete Reasoning over Tabular and Textual Data
+
+Paper: https://arxiv.org/abs/2401.13223
+
+Code: https://github.com/fengbinzhu/TAT-LLM
+
+
+## Introduction
+
+We present TAT-LLM, a specialized language model crafted through the innovative Step-wise Pipeline approach, focusing on the nuanced realm of tabular and textual question answering (QA). This model is the fruit of rigorously fine-tuning the LLaMA 2 architecture with a novel dataset, autonomously generated from expertly annotated resources. TAT-LLM stands at the intersection of tabular comprehension and textual analysis, engineered to excel by embodying three fundamental phases: Extraction, Reasoning, and Execution. Our empirical findings illuminate TAT-LLM's remarkable capability to eclipse traditional benchmarks, surmounting even the most advanced models and colossal language models such as GPT-4 across a suite of demanding QA tasks like FinQA, TAT-QA, and TAT-DQA. This endeavor not only sets a new standard for task-specific language models but also paves the way for future explorations in optimizing smaller models for highly specialized functions.
+
+| Model | Size | FINQA | TATQA | TATDQA |
+| ---   | ---  | ---   | ---   | ---    |
+| GPT-3.5-Turbo | - | 58.00 | 59.47 | 52.74 |
+| GPT-4 | - | 63.91 | 71.92 | 64.46 |
+| TAT-LLM-7B | 7B | 65.13 | 76.49 | 71.38 |
+| TAT-LLM-13B | 13B | 71.93 | 77.51 | 72.22 |
+| TAT-LLM-70B | 70B | **76.81** | **81.42** | **76.55** |
+
+
+## Training
+
+We train our TAT-LLM model in various sizes, including 7B, 13B, and 70B, by fine-tuning LLaMA 2 using Low-Rank Adaptation (LoRa) on a combination of the train sets from FinQA, TAT-QA and TAT-DQA datasets. To refine accuracy, we introduce an External Executor, enhancing the model by processing intermediate outputs to derive conclusive answers.
