"We will upload the data to [Weights & Biases](http://wandb.ai) and use an [Embedding Projector](https://docs.wandb.ai/ref/app/features/panels/weave/embedding-projector) to visualize the embeddings using common dimension reduction algorithms like PCA, UMAP, and t-SNE. The dataset is created in the [Get_embeddings_from_dataset Notebook](Get_embeddings_from_dataset.ipynb)."

"[Weights & Biases](http://wandb.ai) is a machine learning platform used by OpenAI and other ML teams to build better models faster. They use it to quickly track experiments, evaluate model performance, reproduce models, visualize results, and share findings with colleagues."
