Vector Database as a Big Data Analysis Tool for AI Agents

Workflows from the webinar ["Build production-ready AI Agents with Qdrant and n8n"](https://www.youtube.com/watch?v=BQTnXpuH-E).

This series of workflows shows how to build big data analysis tools for production-ready AI agents with the help of vector databases. These pipelines are adaptable to any dataset of images, hence, many production use cases.

1. [Uploading (image) datasets to Qdrant](https://n8n.io/workflows/2654-uploading-image-datasets-to-qdrant-13-anomaly12-knn/) 2. [Set up meta-variables for anomaly detection in Qdrant](https://n8n.io/workflows/2655-set-up-cluster-centresandthresholds-for-anomaly-detection-23-anomaly/) 3. [Anomaly detection tool](https://n8n.io/workflows/2656-anomaly-images-detection-tool-33-anomaly/) 4. [KNN classifier tool](https://n8n.io/workflows/2657-knn-images-classifier-tool-22-knn/)

For anomaly detection 1. This is the first pipeline to upload an image dataset to Qdrant. 2. The second pipeline is to set up cluster (class) centres & cluster (class) threshold scores needed for anomaly detection. 3. The third is the anomaly detection tool, which takes any image as input and uses all preparatory work done with Qdrant to detect if it's an anomaly to the uploaded dataset.

For KNN (k nearest neighbours) classification 1. This is the first pipeline to upload an image dataset to Qdrant. 2. The second is the KNN classifier tool, which takes any image as input and classifies it on the uploaded to Qdrant dataset.

To recreate both You'll have to upload [crops](https://www.kaggle.com/datasets/mdwaquarazam/agricultural-crops-image-classification) and [lands](https://www.kaggle.com/datasets/apollo2506/landuse-scene-classification) datasets from Kaggle to your own Google Storage bucket, and re-create APIs/connections to [Qdrant Cloud](https://qdrant.tech/documentation/quickstart-cloud/) (you can use [Free Tier](https://cloud.qdrant.io/login) cluster), [Voyage AI API](https://www.voyageai.com/) & Google Cloud Storage.

[This workflow] Batch Uploading Images Dataset to Qdrant This template imports dataset images from Google Could Storage, creates Voyage AI embeddings for them in batches, and uploads them to Qdrant, also in batches. In this particular template, we work with [crops dataset](https://www.kaggle.com/datasets/mdwaquarazam/agricultural-crops-image-classification). However, it's analogous to uploading [lands dataset](https://www.kaggle.com/datasets/apollo2506/landuse-scene-classification), and in general, it's adaptable to any dataset consisting of image URLs (as the following pipelines are).
