sseide	001b147450	Documentation fixes (linting and broken links) (#5563 ) # Lint sphinx documentation and fix broken links This PR lints multiple warnings shown in generation of the project documentation (using "make docs_linkcheck" and "make docs_build"). Additionally documentation internal links to (now?) non-existent files are modified to point to existing documents as it seemed the new correct target. The documentation is not updated content wise. There are no source code changes. Fixes # (issue) - broken documentation links to other files within the project - sphinx formatting (linting) ## Before submitting No source code changes, so no new tests added. --------- Co-authored-by: Dev 2049 <dev.dev2049@gmail.com>	1 year ago

Initially, the `MaxMarginalRelevanceExampleSelector` class is used as an `example_selector` argument to the `FewShotPromptTemplate` class. Then, according to the text, a comparison is made to regular similarity search. However, the `FewShotPromptTemplate` still uses the `MaxMarginalRelevanceExampleSelector` class, so the output is the same. To fix it, I added an instantiation of the `SemanticSimilarityExampleSelector` class, because this seems to be what is intended. ## Who can review? @hwchase17	1 year ago

Martin Holecek	44b48d9518	Fix update_document function, add test and documentation. (#5359 ) # Fix for `update_document` Function in Chroma ## Summary This pull request addresses an issue with the `update_document` function in the Chroma class, as described in [#5031](https://github.com/hwchase17/langchain/issues/5031#issuecomment-1562577947). The issue was identified as an `AttributeError` raised when calling `update_document` due to a missing corresponding method in the `Collection` object. This fix refactors the `update_document` method in `Chroma` to correctly interact with the `Collection` object. ## Changes 1. Fixed the `update_document` method in the `Chroma` class to correctly call methods on the `Collection` object. 2. Added the corresponding test `test_chroma_update_document` in `tests/integration_tests/vectorstores/test_chroma.py` to reflect the updated method call. 3. Added an example and explanation of how to use the `update_document` function in the Jupyter notebook tutorial for Chroma. ## Test Plan All existing tests pass after this change. In addition, the `test_chroma_update_document` test case now correctly checks the functionality of `update_document`, ensuring that the function works as expected and updates the content of documents correctly. ## Reviewers @dev2049 This fix will ensure that users are able to use the `update_document` function as expected, without encountering the previous `AttributeError`. This will enhance the usability and reliability of the Chroma class for all users. Thank you for considering this pull request. I look forward to your feedback and suggestions.	1 year ago
Janos Tolgyesi	5f4552391f	Add SKLearnVectorStore (#5305 ) # Add SKLearnVectorStore This PR adds SKLearnVectorStore, a simply vector store based on NearestNeighbors implementations in the scikit-learn package. This provides a simple drop-in vector store implementation with minimal dependencies (scikit-learn is typically installed in a data scientist / ml engineer environment). The vector store can be persisted and loaded from json, bson and parquet format. SKLearnVectorStore has soft (dynamic) dependency on the scikit-learn, numpy and pandas packages. Persisting to bson requires the bson package, persisting to parquet requires the pyarrow package. ## Before submitting Integration tests are provided under `tests/integration_tests/vectorstores/test_sklearn.py` Sample usage notebook is provided under `docs/modules/indexes/vectorstores/examples/sklear.ipynb` Co-authored-by: Dev 2049 <dev.dev2049@gmail.com>	1 year ago

Davis Chase	3be9ba14f3	OpenSearch top k parameter fix (#5216 ) For most queries it's the `size` parameter that determines final number of documents to return. Since our abstractions refer to this as `k`, set this to be `k` everywhere instead of expecting a separate param. Would be great to have someone more familiar with OpenSearch validate that this is reasonable (e.g. that having `size` and what OpenSearch calls `k` be the same won't lead to any strange behavior). cc @naveentatikonda Closes #5212	1 year ago

Jeff Vestal	0b542a9706	Add ElasticsearchEmbeddings class for generating embeddings using Elasticsearch models (#3401 ) This PR introduces a new module, `elasticsearch_embeddings.py`, which provides a wrapper around Elasticsearch embedding models. The new ElasticsearchEmbeddings class allows users to generate embeddings for documents and query texts using a [model deployed in an Elasticsearch cluster](https://www.elastic.co/guide/en/machine-learning/current/ml-nlp-model-ref.html#ml-nlp-model-ref-text-embedding). ### Main features: 1. The ElasticsearchEmbeddings class initializes with an Elasticsearch connection object and a model_id, providing an interface to interact with the Elasticsearch ML client through [infer_trained_model](https://elasticsearch-py.readthedocs.io/en/v8.7.0/api.html?highlight=trained%20model%20infer#elasticsearch.client.MlClient.infer_trained_model) . 2. The `embed_documents()` method generates embeddings for a list of documents, and the `embed_query()` method generates an embedding for a single query text. 3. The class supports custom input text field names in case the deployed model expects a different field name than the default `text_field`. 4. The implementation is compatible with any model deployed in Elasticsearch that generates embeddings as output. ### Benefits: 1. Simplifies the process of generating embeddings using Elasticsearch models. 2. Provides a clean and intuitive interface to interact with the Elasticsearch ML client. 3. Allows users to easily integrate Elasticsearch-generated embeddings.
