Overview

Canso is a Managed Data and Feature Platform for operationalizing Machine Learning initiatives. The goal of Canso is to enable ML Teams (Data Engineers, Data Scientists, ML Engineers) to define their requirements in a declarative and standardized manner via a concise DSL without having to focus on writing custom code for Features, DAGs etc and managing infrastructure. This enables ML teams to

• Iterate fast i.e. move from development to production in hours/days as opposed to weeks
• Promote Reliability i.e build standardized ML pipelines

Canso's core focus is on user experience and speed of iteration, without compromising on reliability -

• Define data sources where features can be created and computed.
• Specify data sinks where processed data is stored after a successful ML pipeline run.
• Define Machine Learning features in a standardized manner on top of existing Datasources and deploy them. These features can be used while Model training as well as for Model inference. Canso supports Raw, Derived and Streaming features currently.
• Register and deploy features to execute the ML pipeline.

User Experience

Getting Started

1. Install Gru Package

For installing gru package will need to username and PAT as password.

• A Personal Access Token (PAT) is a kind of key that authenticates a user across all applications they have access to.

pip3 install git+https://github.com/Yugen-ai/gru.git

2. Create Yugen client

yugen_client = YugenClient(access_token=access_token, config_path="./gru/config.yaml")
