Model Overview

This model, myyycroft/Gemma-4-E2B-AmbigQA-full-member-1, is an ensemble member (seed 1051) of a larger training run, fine-tuned from the google/gemma-4-E2B-it base model. It features 5.1 billion parameters and was specifically adapted using the AmbigQA dataset to handle ambiguous question answering scenarios. The training involved 3 epochs with a learning rate of 2.0e-05 and a maximum sequence length of 512.

Key Characteristics

  • Base Model: Fine-tuned from google/gemma-4-E2B-it.
  • Dataset: Utilizes the sewon/ambig_qa dataset, configured for 'light' processing.
  • Ensemble Member: Represents one of five ensemble members, trained with a specific seed (1051).
  • Training Details: Trained for 3 epochs, completing 1620 steps, with bf16 precision and gradient checkpointing enabled.

Evaluation Metrics (on small subsets)

Evaluation was conducted on small, fixed subsets, not full benchmarks. For this specific member (seed 1051) at the final training step:

  • AmbigQA (128) Accuracy: 0.0859
  • AmbigQA (128) AlignScore: 0.1729
  • IFEval (64) Prompt-level Strict Accuracy: 0.5781
  • MMLU (228) Accuracy: 0.5526

Use Cases

This model is primarily suited for research and development in question answering, particularly for tasks that involve resolving or responding to ambiguous queries. Its fine-tuning on AmbigQA suggests a specialization in understanding and processing questions that may have multiple interpretations or require clarification.
