Construct AI & ML models with JSON using Typescript & Tensorflow
npm install @jsonstack/jsonmJSONM is a module that creates Tensorflow models with JSON.
JSONM is designed so software engineers and machine learning engineers can quickly build, train, save, and load Tensorflow based AI & ML Models. The JSONM Library includes a JSONM UMD module with batteries included so you can use JSONM in the browser without transpilers or any additional setup/configuration. The JSONM UMD is ideal for JAMstack Applications.
The idea behind JSONM is to enable rapid model development. JSONM attempts to automate the data pre-processing and feature engineering needed for most modeling tasks.
Data Scientists who are more comfortable finely tuning hyperparameters and controlling pre-processing, scaling and normalization of datasets can also configure JSONM to meet specific model requirements.

$ npm i @jsonstack/jsonm
