https://github.com/VowpalWabbit/vowpal_wabbit - 9.9.0

This release includes several new reductions including contextual bandits with graph feedback as well as a completely new interaction grounded learning reduction. There are also WASM bindings available for Vowpal Wabbit now.

Contextual Bandits with Graph Feedback

Contextual Bandits (CB) with graph feedback can be used for scenarios where some actions, when taken, reveal information other actions (not taken), or maybe don't reveal any information at all. If there exists prior knowledge of this relationship between actions then that knowledge can be used to make exploration and learning more efficient.

See here for more details.

Contextual Bandits with interaction grounded learning

Interaction grounded learning (IGL) can be used for the scenario where user doesn't have a reward function. It will automatically learn a personalized reward function from user's feedback and optimize directly for the latent user satisfaction

See here for more details

Vowpal Wabbit package in npm

Now that WASM bindings are available, Vowpal Wabbit can be used in JavaScript and TypeScript applications via the npm package. For more details, see here

Eigen Memory Tree

An Eigen Memory Tree (EMT) is a memory based learning reduction. EMTs will remember previous training examples and use this memory to assign labels to future requested predictions. For more information, see the EMT wiki page

Robust confidence sequence estimator

https://github.com/VowpalWabbit/vowpal_wabbit/pull/4297

Cubic config oracle in automl

We are now able to search over cubic interactions on top of quadratic interactions in automl . Automl

Vector CPU instructions

Vector CPU instructions for faster computation in the CB with Large Action Space reduction. LAS

Predict only models

Ability to save predict only models from some reductions (automl, epsilon-decay).  this removes the reductions from the reduction stack and allows older versions of VW to predict.

Enforce minimum probability for SquareCB

SquareCB

Support for probabilities for PLT

Added support for probabilities output for the PLT reduction + fix it in version 9+.

Target rate added to explore eval

The goal of explore eval is to evaluate different exploration algorithms using the data from a logged policy. Explore Eval

VW refactors

• Improved finish_example in all reductions
• Parsers for different formats moved into their own libraries
• Namespacing of library fixed - all things under VW

Large Action Spaces

This introduces the Large Actions Spaces (LAS) feature. LAS is an algorithm that lets exploration happen efficiently when there are a large number of actions in a contextual bandit dataset. The main idea behind it is to eliminate actions that are similar and explore only over the most diverse actions in the dataset. For more information, see the LAS wiki page.

Style Changes

This release introduces additional style changes to make VW code formatting more consistent. Variable and type names are snake_case, constants and macros are UPPERCASE, and the VW::details namespace is used to hide implementation details.

Faster Compile Times

Through @jackgerrits's changes to some header files, VW now builds much faster! On one machine, compile times went from around 30 seconds to 17.

Style Changes

This release includes some improvements to the style and naming conventions in VW. This includes using snake_case for all variable and class names, and converting most structs to classes. These style changes will be standardized and enforced in later releases.

Confidence Sequence Estimator

Confidence sequences have become the default estimators when evaluating policies in multi-model reductions such as AutoML and Epsilon Decay.

https://github.com/VowpalWabbit/vowpal_wabbit - 9.4.0

We tagged 9.4.0 a few weeks ago but a few delays caused the rest of the release to only be completed now. The contents of these release notes and all associated artifacts correspond to the 9.4.0 tag on September 15.

DotNet Core

DotNet core support is here! It works if you manually import dependencies, but it will become automatic in the upcoming 9.4.1.

Native CSV Parser

As part of RLOS Fest this year @HollowMan6 implemented Native CSV parsing support. It is currently disabled by default but is available using a CMake option (VW_BUILD_CSV). This feature makes it possible to download CSV datasets and process them without any extra steps. @HollowMan6 also created a tutorial to explain how to use the feature on the well known iris dataset. Thanks for all of your hard work!

https://github.com/VowpalWabbit/vowpal_wabbit - 8.7.0

• The repo has moved to the VowpalWabbit organization
• The group of core maintainers has been growing with steady improvements

Changes

As always, lots of bug fixes.

Build System

The build system for VW has been overhauled to use CMake. This means, easier dependency resolution, faster build times and easier consumption as a dependency. The old automake + make systems have been replaced by this and eventually the .sln file will be replaced too. (#1624)

Reductions/Learning Algorithms

• Coin betting (#1903)
• Contextual Memory Tree (#1799)
• Warm start for cbify (#1534)
• Softmax learner for cbadf (#1839)
• cbify: --cbifyldf for multiline (csoaaldf input datasets (#1681))

Other Improvements

• The parser has moved to using std types for concurency and has a clearer data production model. You’ll slowly notice more RAII types in VW. (#1731) (#1777)
• A clang format file was added and the codebase reformatted. This is to keep things more consistent and easy to read. (#1701)
• The Python bindings can now use JSON as the input format, as long as the VW instance you’re using is configured to be parsing input as JSON (#1809)
• A new --strict_parse option was added to throw instead of warn for malformed examples (#1906)
• Bare Java JNI Bindings optimized for Apache Spark (#1798)
• Add multiclass support for hyperopt utl (#1682)

The internal version number now matches the tag number

https://github.com/VowpalWabbit/vowpal_wabbit - 8.6.0

This version has many bug fixes of course. In addition, (1) There are many improvements to the contextual bandit code thanks to Alberto Bietti (https://arxiv.org/abs/1802.04064 ). (2) There are significant improvements to save_resume due to @denik.

Internally, (a) The argument parsing code has been rewritten to be more consistent throughout the code base via parser_helper.h. (b) There are significant improvements in the way that multiline examples are handled thanks to @rajan-chari

Note that unlike previous release versions, I've left the "Makefile" build system in place rather than using Automake. Automake is still available if desired, but you'll need to run it manually if you want to use it.

8.5.0 has further improvements, including fully working sparse model support, empirically optimized exploration algorithms, a new cost-sensitive active learning algorithm (https://arxiv.org/abs/1703.01014), and baseline prediction support.

There aren’t many new features since 8.3.0 (better JSON language support, better offline eval, sparse parameter support), so this version simply addresses a number of issues that have shown up over time

Many things added including more sophisticated contextual bandits, the recall tree, and OjaNewton.
