Scaling Up Optuna: P2P Distributed Hyperparameters Optimization
Concurrency Computation Practice and ExperienceABSTRACT In machine learning (ML), hyperparameter optimization (HPO) is the process of choosing a tuple of values that ensures an efficient deployment and training of an AI model. In practice, HPO not only applies to ML tuning but can also be used to tune complex numerical simulations.

OLGBM: Optuna Optimized Light Gradient Boosting Machine for Intrusion Detection
2021 International Conference on Computer, Communication, Chemical, Materials and Electronic Engineering (IC4ME2), 2021Network technology has been evolved exponentially in the past few decades. At the same time, gazillions of network intrusion incidents are continuously forming cyberspace a shocking vulnerable domain to explore for the personnel from armature to the professionals. Consequently, networks mostly become botnet when there are no Intrusion Detection Systems

We can now create an efficient model using the techniques that were discussed in the previous chapters. Bayesian optimization goes a long way in finding hyperparameters. This chapter provides an overview of the Optuna framework and discusses further the role of hyperparameter optimization in automated machine learning.
