We tried different methods, including k-nearest neighbor (k-NN) search of vector embeddings, BM25 with synonyms , and a hybrid of both across fields including API routes, descriptions, and hypothetical questions. Having similar names and synonyms in API routes make this retrieval problem more complex.

To demonstrate this concept, I wrote a short demo in just ten lines of Python code using the k-nearest neighbors algorithm (KNN). argsort()] # Get the top k closest indices closest_k_indices = sorted_distances[:k, 1].astype(int)

For demo purposes, we use approximately 1,600 products. We use the first metadata file in this demo. We use a pretrained ResNet-50 (RN50) model in this demo. We only use the item images and item names in US English. For more details about this dataset, refer to the README. The dataset is hosted in a public S3 bucket.

Testing the Streamlit app in a SageMaker environment is intended for a temporary demo. find_similar_items performs semantic search using the k-nearest neighbors (kNN) algorithm on the input image prompt. In the demo, we use the luxury brand and the fast fashion brand, each with its own preferences and guidelines.
