Overview
Intelli ML makes machine learning, and AI more accessible and more performant. Use this software platform for building custom models on the cloud. Enterprises can rapidly deploy instances fully optimized with blazing performance. The Intelli ML platform includes the most popular machine learning frameworks and their dependencies, and it is built for easy and rapid deployment. Users can also learning Machine Learning in the platform itself and become a professional while using the platform to build ML solutions.
Beginner's Guide
Artificial intelligence will shape our future more powerfully than any other innovation this century. Anyone who does not understand it will soon find themselves feeling left behind, waking up in a world full of technology that feels more and more like magic.
Machine Learning (ML) is defined as the use algorithms and computational statistics to learn from data without being explicitly programmed. It is a subsection of the artificial intelligence domain within computer science. While the field of machine learning did not explode until more recently, the term was first coined in 1959 and the most foundational research was done throughout the 70’s and 80's. Machine learning’s rise to prominence today has been enabled by the abundance of data, more efficient data storage, and faster computers.
Terminologies
Training Data : The data you use for training your model. It contains all the information you have collected about the problem statement.
Test Data : The data you use for testing the model. You can make predictions on this data.
Features : These are all the columns in your dataset which you use for training your model.
Class/Label : This is the column which identifies the particular record and the one you want to predict.
Accuracy : This is the percentage of data correctly predicted when you apply the model to your data.
Quickstart
Following : 3 services are provided by Phoenix ML as part of Release 1.2.0.
Classification : Classify entities into binary or multi classes.
Regression : Predict a value from a continuous range.
Feedback : Training a model with new set od data.
Clustering : Cluster your dataset based on yout business needs.
