    ## How to Get Started with the Model Use the code below to get started with the model. ```python from transformers import AutoModelForSeq2SeqLM, AutoTokenizer model = AutoModelForSeq2SeqLM.from_pretrained("smartcat/T5-GenQ-T-v1") tokenizer = AutoTokenizer.from_pretrained("smartcat/T5-GenQ-T-v1") description = "Silver-colored cuff with embossed braid pattern. Made of brass, flexible to fit wrist." inputs = tokenizer(description, return_tensors="pt", padding=True, truncation=True) generated_ids = model.generate(inputs["input_ids"], max_length=30, num_beams=4, early_stopping=True) generated_text = tokenizer.decode(generated_ids[0], skip_special_tokens=True) ``` ## Training Details ### Training Data The model was trained on the [smartcat/Amazon-2023-GenQ](https://huggingface.co/datasets/smartcat/Amazon-2023-GenQ) dataset, which consists of user-like queries generated from product descriptions. The dataset was created using Claude Haiku 3, incorporating key product attributes such as the title, description, and images to ensure relevant and realistic queries. For more information, read the Dataset Card. 😊 ### Preprocessing - Trained on only the product titles - Tokenized using T5’s default tokenizer with truncation to handle long text. ### Training Hyperparameters ### Train time: 2.43 hrs ### Hardware A6000 GPU: - Memory Size: 48 GB - Memory Type: GDDR6 - CUDA: 8.6 ### Metrics **[ROUGE](https://en.wikipedia.org/wiki/ROUGE_(metric))**, or **R**ecall-**O**riented **U**nderstudy for **G**isting **E**valuation, is a set of metrics used for evaluating automatic summarization and machine translation in NLP. The metrics compare an automatically produced summary or translation against a reference or a set of references (human-produced) summary or translation. ROUGE metrics range between 0 and 1, with higher scores indicating higher similarity between the automatically produced summary and the reference. In our evaluation, ROUGE scores are scaled to resemble percentages for better interpretability. The metric used in the training was ROUGE-L.

    ### Model Analysis
    Average scores by model
    image The checkpoint-29995 (T5-GenQ-T-v1) model outperforms query-gen-msmarco-t5-base-v1 across all ROUGE metrics. The largest performance gap is in ROUGE2, where checkpoint-29995 achieves 52.27, whereas query-gen-msmarco-t5-base-v1 scores 19.52. ROUGE1, ROUGEL, and ROUGELSUM scores are very similar in both trends, with checkpoint-29995 consistently scoring above 72, while query-gen-msmarco-t5-base-v1 stays below 41.
    Density comparison
    image ```T5-GenQ-T-v1``` - Higher concentration of high ROUGE scores, especially near 100%, indicating strong text overlap with references. ```query-gen-msmarco-t5-base-v1``` – more spread-out distribution, with multiple peaks at 10-40%, suggesting greater variability but lower precision. ROUGE-1 & ROUGE-L: ```T5-GenQ-T-v1``` peaks at 100%, while ```query-gen-msmarco-t5-base-v1``` has lower, broader peaks. ROUGE-2: ```query-gen-msmarco-t5-base-v1``` has a high density at 0%, indicating many low-overlap outputs.
    Histogram comparison
    image ```T5-GenQ-T-v1``` – higher concentration of high ROUGE scores, especially near 100%, indicating strong text overlap with references. ```query-gen-msmarco-t5-base-v1``` – more spread-out distribution, with peaks in the 10-40% range, suggesting greater variability but lower precision. ROUGE-1 & ROUGE-L: ```T5-GenQ-T-v1``` shows a rising trend towards higher scores, while ```query-gen-msmarco-t5-base-v1``` has multiple peaks at lower scores. ROUGE-2: ```query-gen-msmarco-t5-base-v1``` has a high concentration of low-score outputs, whereas ```T5-GenQ-T-v1``` achieves more high-scoring outputs.
    Scores by generated query length
    image This visualization analyzes average ROUGE scores and score differences across different query sizes. High ROUGE Scores for Most Sizes (3-9 words). ROUGE-1, ROUGE-2, ROUGE-L, and ROUGE-LSUM scores remain consistently high across most word sizes. Sharp Spike at Size 2: A large positive score difference at 2 words, suggesting strong alignment for very short phrases. Stable Score Differences (Sizes 3-9): After the initial spike at size 2, score differences stay close to zero, indicating consistent performance across phrase lengths.
    Semantic similarity distribution
    image This histogram visualizes the distribution of cosine similarity scores, which measure the semantic similarity between paired texts. The majority of similarity scores cluster near 1.0, indicating that most text pairs are highly similar. A gradual increase in frequency is observed as similarity scores rise, with a sharp peak at 1.0. Lower similarity scores (0.0–0.4) are rare, suggesting fewer instances of dissimilar text pairs.
    Semantic similarity score against ROUGE scores
    image This scatter plot matrix compares semantic similarity (cosine similarity) with ROUGE scores, showing their correlation. Higher similarity → Higher ROUGE scores, indicating strong n-gram overlap in semantically similar texts. ROUGE-1 & ROUGE-L show the strongest correlation, while ROUGE-2 has more variability. Low-similarity outliers exist, where texts share words but differ semantically.
