Architecture

karura has insights.

Each insight gets the data and judges the necessity of its adoption, and if it needed, execute it.

For example, NAFrequencyCheckInsight watches the amount of the NA in each column, and if it is too high, then drop the column. Of course, you can confirm it to the user.

karura can have many insights, so you can add the insight as you needed.

stack_insights

Insights are adopted according to the InsightIndex order.
And you can create custom insight by inheriting the Insight class.

tornado
cryptography
pymongo (Also needs MongoDB)

As Slackbot

You can communicate with karura on Slack!

When you upload the csv file or tell kintone app name to karura, then interaction starts.You can build your own machine learning model interactively, and also you can get some suggestions about the data treatment from karura.

As Adviser on kintone

You can ask karura to analyze your kintone app!

Select the target app
Select the field that you want to predict and fields that you use to do it
Push Train button

Then, you can get analyzed result!

Setup

Slackbot

Use Dockerfile_slackbot
set below environmental variables
