Differential privacy, an easy case

Accuracy and Privacy • 1 HN point • 02 Jan 19
🕹 Technology Privacy Statistics Data Collection Data processing
  1. Differential privacy is a mathematical definition of privacy specifically designed for protecting personal data in a world of big data and computation.
  2. Privacy protection in differential privacy comes from adding randomness or noise to data before publishing, where more noise equals greater privacy protection.
  3. There is a tradeoff between accuracy and privacy in differential privacy, as the level of uncertainty introduced for privacy protection can impact the accuracy of conclusions drawn from the data.

To Infinity and Beyond: Scaling Stream Processing

Bytewax • 0 implied HN points • 03 Oct 23
🕹 Technology Data processing Scaling System Design
  1. Bytewax has rescaling capabilities since version 0.17, allowing you to change the number of workers contributing to a dataflow cluster without losing data.
  2. Horizontal rescaling involves adding or removing workers from a cluster-based system to adjust computational resources.
  3. Bytewax utilizes state snapshots, primary assignment systems, and consistent routing to enable start-stop rescaling for streaming dataflows.

Comparing Stateful Stream Processing and Streaming Databases

Tributary Data • 0 implied HN points • 29 Sep 22
🕹 Technology Data processing Streaming Querying
  1. Stateful stream processors and streaming databases have different approaches in handling data ingestion and state persistence.
  2. Stream processors require knowing and embedding state manipulation logic in advance, while streaming databases offer ad-hoc manipulation by consumers.
  3. Stream processors are ideal for automated, machine-driven decision-making, while streaming databases cater to human decision-makers needing fast, ad-hoc data access.

Notes from a Lost Future of AI Art

Cybernetic Forests • 0 implied HN points • 13 Nov 22
🕹 Technology AI Art Image Generation Model Training Data processing Creative Process
  1. Generative adversarial networks (GANs) were used in AI art and photography to understand the fundamentals of AI image generation, before being largely replaced by Diffusion models.
  2. To be an AI photographer, learn what the AI requires to work efficiently, take numerous photographs (500-1500), and capture the space around interesting elements to create patterns.
  3. After obtaining a dataset of images, cropping, rotating, and reversing them can significantly increase the dataset size, leading to different outcomes when training a model, which can be done efficiently using tools like RunwayML.
