Talos radically changes the ordinary Keras workflow by fully automating hyperparameter tuning and model evaluation. Talos exposes Keras functionality entirely and there is no new syntax or templates to learn.

Talos

TL;DR

Talos radically transforms ordinary Keras workflows without taking away any of Keras.

• works with ANY Keras model
• takes minutes to implement
• no new syntax to learn
• adds zero new overhead to your workflow

Talos is made for data scientists and data engineers that want to remain in complete control of their Keras models, but are tired of mindless parameter hopping and confusing optimization solutions that add complexity instead of reducing it. Within minutes, without learning any new syntax, Talos allows you to configure, perform, and evaluate hyperparameter optimization experiments that yield state-of-the-art results across a wide range of prediction tasks. Talos provides the simplest and yet most powerful available method for hyperparameter optimization with Keras.

🔧 Key Features

Based on what no doubt constitutes a "biased" review (being our own) of more than ~30 hyperparameter tuning and optimization solutions, Talos comes on top in terms of intuitive, easy-to-learn, highly permissive access to critical hyperparameter optimization capabilities. Key features include:

• Single-line optimize-to-predict pipeline talos.Scan(x, y, model, params).predict(x_test, y_test)
• Automated hyperparameter optimization
• Model generalization evaluator
• Experiment analytics
• Pseudo, Quasi, and Quantum Random search options
• Grid search
• Probabilistic optimizers
• Single file custom optimization strategies
• Dynamically change optimization strategy during experiment
• Support for man-machine cooperative optimization strategy
• Model candidate generality evaluation
• Live training monitor
• Experiment analytics

Talos works on Linux, Mac OSX, and Windows systems and can be operated cpu, gpu, and multi-gpu systems.
