pybandits.core.smab

-
-
-class pybandits.core.smab.Smab(action_ids, success_priors=None, failure_priors=None, random_seed=None)
-

Bases: object

-

Stochastic Multi-Armed Bandit for Bernoulli bandits with Thompson Sampling.

-
-
Parameters
-
    -

  • action_ids (List[str]) – List of possible actions

    • -

  • success_priors (Dict[str, int]) – Dictionary containing the prior number of positive feedback (successes) for each action. keys are -action IDs and values are successes counts. If None, each action’s prior is set to 1 by default. -Success counts must be integers and > 0.

    • -

  • failure_priors (Dict[str, int]) – Dictionary containing the prior number of negative feedback (failures) for each action. keys are -action IDs and values are failures counts. If None, each action’s prior is set to 1 by default. -Failure counts must be integers and > 0.

    • -

  • random_seed (int) – Seed for random state. If specified, the model outputs deterministic results.

    • -
-
-
-
-
-batch_update(batch)
-

This method updates the SMAB for several action IDs at once, iterating over the batch.

-
-
Parameters
-

batch (List[dict]) – List of dicts in the form [{‘action_id’: <str>, ‘n_successes’: <int>, ‘n_failures’:<int>}]

-
-
-
- -
-
-predict(n_samples=1, forbidden_actions=None)
-

Predict the best actions by randomly drawing samples from a beta distribution for each possible action. -The action with the highest value is recommended to the user as the ‘best action’ considering current -information. The Beta distributions’ alpha and beta parameters for each action are its associated counts -of success and failure, respectively.

-
-
Parameters
-
    -

  • n_samples (int) – Number of samples to predict (default 1).

    • -

  • forbidden_actions (List[str]) – List of forbidden actions. If specified, the model will discard the forbidden_actions and it will only -consider the remaining allowed_actions. By default, the model considers all actions as allowed_actions. -Note that: actions = allowed_actions U forbidden_actions.

    • -
-
-
Returns
-

    -

  • best_actions (list) – The best actions according to the model, i.e. the actions whose distribution gave the greater sample.

    • -

  • probs (list) – The probabilities to get a positive reward for each action.

    • -
-

-
-
-
- -
-
-update(action_id, n_successes, n_failures)
-

This method updates the SMAB with feedbacks for a given action. The action’s associated success (resp. -failure) counter is incremented by the number of successes (resp. failures) received.

-
-
Parameters
-
    -

  • action_id (str) – The ID of the action to update.

    • -

  • n_successes (int) – The number of successes received for action_id.

    • -

  • n_failures (int) – The number of failures received for action_id.

Multi-Armed Bandit Library

-Build Status -Documentation Status -Code coverage -Version -Version -

PyBandits is a Python library for Multi-Armed Bandit (MAB) developed by the Playtika AI lab. We developed this tool in order to provide personalised recommendation. It provides an implementation of stochastic Multi-Armed Bandit (sMAB) and contextual Multi-Armed Bandit (cMAB) based on Thompson sampling.

-

In a bandit problem, a learner recommends an action to a user and observes a reward from the user for the chosen action. Information is then used to improve learner prediction for the next user.

-

For the stochastic multi-armed bandit (sMAB), -we implemented a Bernoulli multi-armed bandit based on Thompson sampling algorithm -(Agrawal and Goyal, 2012). -If user information is available (‘context’), a generalisation of Thompson Sampling for cMAB (Agrawal and Goyal, 2014) has been implemented using PyMC3.

-

PyMC3 is an open source -probabilistic programming framework that allows for automatic Bayesian inference on user-defined probabilistic -models. A major advantage of this package is its flexibility and extensibility that allows -the implementation of a large variety of models for prior and likelihood distributions. Currently the cMAB implements a robust logistic regression for binary rewards (Bernoulli bandit) with Student-t priors. A robust regression -is less sensitive to outliers since Student’s T for prior distributions have wider tails than Normal distributions. -Despite binary reward is very common, the package will be updated in order to extend to other reward definitions. -However, as an open-source package, modification can easily be applied to our functions in order to modify priors -and/or likelihood distributions as described in PyMC3 documentation for the cMAB. -In order to observed bandit behaviours based on different assumptions (sample size, reward probabilities, -number of actions, context dimension …) or validate modifications, a simulation process is available. One can -simulate data using different parameters setting, apply sMAB or cMAB and observe recommendation efficiency.
