RESTful AI Demo

Introduction

RESTful AI Demo (RAID) is a simple set of APIs for learning machine learning (ML) and deep learning (DL). It is written in Java Spring Boot and consists of two components:

Zoo Chatbot (ML): enquires about a zoo, based on Apache OpenNLP natural language processing (NLP).
Handwriting Recogniser (DL): recognition of handwritten digits, based on Deep Java Library (DJL) image recognition.

Definitions of machine learning and deep learning

ML is a subset of AI and DL is a subset of ML:

Machine learning

Typically involves providing an algorithm with example input and corresponding output data, then letting the algorithm run iteratively to learn the nature of these mappings
Iteratively adjusts its parameters and compares its calculated output, derived from the input, to the defined output
Once the model is trained in this manner it can predict the classification of relevant input

Deep learning

Similar to ML in that it also learns through an iterative algorithm
Typically uses much more input data and stores its calculations in a neural network structure
The data and relationships of data are stored as nodes and weighted vectors
Powerful enough to learn on its own, without provision of example output
