Visualizing Cross-validation Code

Visualizing Cross-validation Code  #MachineLearning #dataviz

  • Let us say, you are writing a nice and clean Machine Learning code (e.g. Linear Regression).
  • As the name of the suggests, cross-validation is the next fun thing after learning Linear Regression because it helps to improve your prediction using the K-Fold strategy.
  • But we divide the dataset into equal K parts (K-Folds or cv).
  • Then train the model on the bigger dataset and test on the smaller dataset.
  • This graph represents the k- folds Cross Validation for the Boston dataset with Linear Regression model.


Cross-validation helps to improve your prediction using the K-Fold strategy. What is K-Fold you asked? Check out this post for a visualized explanation.

Blockchains are a data buffet for AIs – Fred Ehrsam – Medium

  • And while many of the tech giants working on AI like Google and Facebook have open sourced some of their algorithms, they hold back most of their data.In contrast, blockchains represent and even incent open data.
  • For example: creating a decentralized Uber requires a relatively open dataset of riders and drivers available to coordinate the network.The network effects and economic incentives around these open systems and their data can be more powerful than current centralized companies because they are open standards that anyone can build on in the same way the protocols of the internet like TCP/IP, HTML, and SMTP have achieved far greater scale than any company that sits atop them.
  • And oracle systems (a fancy way of saying getting people all over the world to report real world information to the blockchain in a way we can trust) like Augur will inject more data.This open data has the potential to commoditize the data silos most tech companies like Google, Facebook, Uber, LinkedIn, and Amazon are built on and extract rent from.
  • AIs trained on open data are more likely to be neutral and trustworthy instead of biased by the interests of the corporation who created and trained them.Since blockchains allow us to explicitly program incentive structures, they may make the incentives of AI more transparent.Simplified, AI is driven by 3 things: tools, compute power, and training data.
  • My guess is they shift to 1) creating blockchain protocols and their native tokens and 2) AIs that leverage the open, global data layer of the blockchain.

Sam Altman recently wrote that we are entering an era of hyperscale technology companies. These companies own massive troves of data with strong network effects around them and they are only getting…

Tech billionaires donate $20m to fund set up to protect society from AI

Tech billionaires donate $20m to the Ethics and Governance of Artificial Intelligence Fund

  • ‘There’s an urgency to ensure that AI benefits society and minimises harm,’ said LinkedIn founder Hoffman.
  • LinkedIn and eBay founders Reid Hoffman and Pierre Omidyar donate $10m each to the Ethics and Governance of Artificial Intelligence Fund
  • The fund is one of many new bodies aimed at shaping the future of AI in a positive – or, at least, thoughtful – direction.
  • The founders of LinkedIn and eBay are donating a combined $20m (£16.4m) to fund academic research aimed at ensuring the safety of artificial intelligences.
  • LinkedIn’s founder Reid Hoffman and the Omidyar network, the philanthropic investment firm set up by eBay founder Pierre Omidyar, are donating $10m each to the Ethics and Governance of Artificial Intelligence Fund, which will distribute money to researchers working on the tough ethical problems raised by AI.
