H&M Personalized Fashion Recommendations - Enhanced Dataset

Dataset Description

This dataset is a processed and enhanced version of the H&M Personalized Fashion Recommendations Kaggle competition dataset. The original dataset has been cleaned and augmented with pre-computed embeddings and accessible image URLs to facilitate fashion recommendation research and multimodal retrieval applications.

Dataset Summary

The H&M dataset contains rich product metadata, customer information, and transaction history from H&M's e-commerce platform. This enhanced version includes:

• ~106,000 fashion products with detailed metadata
• ~1.37 million customers with demographic information
• Historical transaction data for recommendation modeling
• Product images accessible via S3 URLs
• Pre-computed dense embeddings (BGE-small-en-1.5)
• Pre-computed sparse embeddings (SPLADEv1)

Languages

• English (product descriptions and metadata)

Enhancements Over Original Dataset

This processed version includes the following improvements:

1. Data Cleaning: Removed all null values for improved data quality
2. Image Accessibility: All product images uploaded to S3 with direct URL access via image_url field
3. Dense Embeddings: Pre-computed BGE-small-en-1.5 embeddings for efficient semantic search
4. Sparse Embeddings: Pre-computed SPLADEv1 embeddings for keyword-based retrieval

Dataset Creation

Source Data

The original dataset was created by H&M Group for a Kaggle competition aimed at developing personalized fashion recommendation systems. The data represents real customer transactions and product catalog information.

Processing Pipeline

1. Data Loading: Original CSV files from Kaggle competition
2. Null Removal: Filtered out records with missing critical fields
3. Image Upload: Product images uploaded to S3 for reliable access
4. Embedding Generation:
   • BGE-small-en-1.5: Dense embeddings generated from product descriptions and metadata
   • SPLADEv1: Sparse embeddings for efficient lexical matching
5. Quality Validation: Verified embedding dimensions and data integrity

Embedding Models

BGE-small-en-1.5

• Model: BAAI/bge-small-en-v1.5
• Dimension: 384
• Use Case: Dense semantic retrieval, similarity search
• Input: Product descriptions and relevant metadata fields

SPLADEv1

• Model: SPLADE (Sparse Lexical and Expansion Model)
• Type: Learned sparse representation
• Use Case: Keyword-based retrieval, interpretable search

Uses

Direct Use

This dataset is ideal for:

• Fashion recommendation systems: Product-to-product and user-to-product recommendations
• Multimodal retrieval: Combining text and image features for search
• Embedding evaluation: Benchmarking dense and sparse retrieval methods
• Fashion trend analysis: Understanding product categorization and customer preferences
• Vector database applications: Testing and demonstrating retrieval systems (e.g., with Qdrant, Pinecone, Weaviate)

Use Cases

from datasets import load_dataset

# Load the dataset
dataset = load_dataset("your-username/hm-fashion-enhanced")

# Example 1: Semantic search using BGE embeddings
query_embedding = model.encode("casual summer dress")
# Use embeddings for similarity search in your vector database

# Example 2: Hybrid search combining dense and sparse
# Combine BGE dense embeddings with SPLADE sparse for best results

# Example 3: Fashion recommendation
# Use transaction history + embeddings for personalized recommendations

Considerations for Using the Data

Social Impact

Fashion recommendation systems can influence purchasing decisions and consumer behavior. Consider:

• Diversity: Ensure recommendations don't reinforce narrow beauty standards
• Inclusivity: Product recommendations should serve diverse customer demographics
• Sustainability: Consider environmental impact of fast fashion recommendations

Limitations

• Temporal Scope: Data covers 2018-2020; fashion trends evolve rapidly
• Geographic Bias: Primarily represents European H&M markets
• Demographic Representation: Customer demographics may not represent global population
• Cold Start: Limited data for new products and customers
• Null Removal: Some products excluded due to missing data

Privacy

• Customer data has been anonymized
• No personally identifiable information (PII) included
• Transaction history anonymized with customer IDs
