Monthly Report April 2019

[Updated May 13, 2019]


  • Added Reward details to the uncle block in our blockchain browser to provide more detailed information.

  • Developed and deployed Ledger dashboard for each ledger to better monitor the reward, tasks and AI workers.
  • Upgraded Orion API to improve the user experience and performance.
  • Fixed link in our blockchain browser


Open Source Codes

In the end of April, we released several open source code, including AI worker version 1.0, NBAI blockchain and node, blockchain browser, Orion Convertor. A set of AI testing models were also released for testing the usability and compatibility of Orion cloud platform. We’ve been collecting and using feedbacks to continually improve the performance of the platform.

Keras: A popular deep learning framework written in Python. It takes the built in MNIST dataset for training handwritten digit recognition.

Mnist: A computer vision dataset widely used for training and testing in the field of machine learning.We use the MNIST dataset to train the generator and discriminator for GAN.

Word2Vec: One of the most popular technique to learn word embeddings using shallow neural network, a sample script for testing AI Worker, also a default script offered when you sign up as an AI User.

Orion-translator: This is a testing code base on Pytorch framework. The model trains a neural network to translate from French to English.

KMeans: One of the most classic algorithms in data mining. This code aims to find the 66 optimized fire stations locations based on the fire intervention data.

Orion-image-encoder-decoder: Using CF-10 image dataset to train encoder and decoder for reducing image noises.
