Introduction to SQL - Part 7 - SQL Operator

SQL Operator

An SQL operator is a special word or character used to perform tasks. These tasks can be anything from complex comparisons, to basic arithmetic operations. Think of an SQL operator as similar to how the different buttons on a calculator function.

SQL operators are primarily used within the WHERE clause of an SQL statement. This is the part of the statement that is used to filter data by a specific condition or conditions.

There are six types of SQL operators that we are going to cover: Arithmetic, Bitwise, Comparison, Compound, Logical and String.

Prompt Engineering Fundamentals

Introduction Generative AI is a transformative technology capable of producing text, images, audio, and code in response to user prompts. This capability is powered by Large Language Models (LLMs) like OpenAI's GPT series, which are trained to understand and generate natural language. Interacting with these models via prompts allows users to harness their potential without needing technical expertise. This chapter explores the essentials of prompt engineering, a field dedicated to optimizing prompt design for consistent and high-quality responses. Learning Goals By the end of this lesson, you will be able to: Explain what prompt engineering is and why it matters. Describe the components of a prompt and how they are used. Learn best practices and techniques for prompt engineering. Apply learned techniques to real examples using an OpenAI endpoint. Learning Sandbox Prompt engineering is more art than science, requiring practice and iterative refinement. This lesson includes a Jupyt...

AWS Cloud Containers

Amazon Web Services (AWS) offers a variety of services for deploying and managing applications in the cloud. One of these services is called Amazon Elastic Container Service (ECS), which allows you to run and manage Docker containers on AWS. Here is a brief overview of how Amazon ECS works: You package your application into a Docker container image and push it to a registry, such as Amazon Elastic Container Registry (ECR) or Docker Hub. You create an Amazon ECS task definition, which is a blueprint for your containerized application. The task definition specifies things like the Docker image to use, the CPU and memory requirements, and the environment variables to pass to the container. You create an Amazon ECS cluster, which is a group of Amazon EC2 instances that are running the Amazon ECS container agent. The cluster is where your tasks are placed and run. You create an Amazon ECS service, which is a long-running task that is hosted on your cluster. The service ensures that a speci...

Identified COVID-19 in X-ray images with deep learning.

Project structure : Our coronavirus (COVID-19) chest X-ray data is in the dataset/ directory where our two classes of data are separated into covid/ and normal/ I have created train_covid19.py file to train the model. Three command line arguments (parameters) required to run this file : --dataset: The path to our input dataset of chest X-ray images. --plot: An optional path to an output training history plot. By default the plot is named plot.png unless otherwise specified via the command line. --model: The optional path to our output COVID-19 model; by default it will be named covid19.model. To load our data, we grab all paths to images in in the --dataset directory. Then, for each imagePath, we: · Extract the class label (either covid or normal) from the path. · Load the image, and preprocess it by convertin...
