We detail the steps to use an Amazon Titan Multimodal Embeddings model to encode images and text into embeddings, ingest embeddings into an OpenSearch Service index, and query the index using the OpenSearch Service k-nearest neighbors (k-NN) functionality. These steps are completed prior to the user interaction steps.

We use OpenSearch Serverless as a vector database for storing embeddings generated by the Titan Multimodal Embeddings model. In the user interaction phase, a question from the user is converted into embeddings and a similarity search is run on the vector database to find a slide that could potentially contain answers to user question.

Let us first understand the meaning of bias and variance in detail: Bias: It is a kind of error in a machine learning model when an ML Algorithm is oversimplified. It is introduced into an ML Model when an ML algorithm is made highly complex. In such types of questions, we first need to ask what ML model we have to train.
