How to Change the Root Device Volume to Persist


By default, the root device volume for an AMI backed by Amazon EBS is deleted when the instance terminates. To change the default behavior, set the DeleteOnTermination flag to false in the instance's block device mapping.

AWS Management Console

To change the root device volume to persist when you launch an instance
  1. Open the Amazon EC2 console at https://console.aws.amazon.com/ec2/.
  2. From the Amazon EC2 console dashboard, click Launch Instance.
  3. On the Choose an Amazon Machine Image (AMI) page, choose the AMI to use and click Select.
  4. Follow the wizard to complete the Choose an Instance Type and Configure Instance Details pages.
  5. On the Add Storage page, deselect the Delete On Termination check box for the Root volume.
  6. Complete the remaining wizard pages, and then click Launch.
You can verify the setting by viewing details for the root device volume on the instance's details pane in the AWS Management Console. Next to Block devices, click the entry for the root device volume. By default, Delete on termination is True. If you change the default behavior, Delete on termination is False.

How are vector databases used?

  Vector Databases Usage: Typically used for vector search use cases such as visual, semantic, and multimodal search. More recently, they are paired with generative AI text models for conversational search experiences. Development Process: Begins with building an embedding model designed to encode a corpus (e.g., product images) into vectors. The data import process is referred to as data hydration. Application Development: Application developers utilize the database to search for similar products. This involves encoding a product image and using the vector to query for similar images. k-Nearest Neighbor (k-NN) Indexes: Within the model, k-nearest neighbor (k-NN) indexes facilitate efficient retrieval of vectors. A distance function like cosine is applied to rank results by similarity.

Feature Engineering - What and Why

Feature engineering is a crucial step in the machine learning pipeline where you create new, meaningful features or transform existing features to improve the performance of your predictive models. It involves selecting, modifying, or creating features from your raw data to make it more suitable for machine learning algorithms. Here's a more detailed overview of feature engineering: Why Feature Engineering? Feature engineering is essential for several reasons: Improving Model Performance: Well-engineered features can significantly boost the predictive power of your machine learning models. Handling Raw Data: Raw data often contains noise, missing values, and irrelevant information. Feature engineering helps in cleaning and preparing the data for analysis. Capturing Domain Knowledge: Domain-specific insights can be incorporated into feature creation to make the model more representative of the problem. Common Techniques and Strategies: 1. Feature Extraction: Transforming raw data
