Let's #UnlockStats - Extending #UnlockAI

by Atul Singh / in #UnlockAI, #UnlockStats, Concept, Learning, Machine Learning, ML, Statistics, Stats /

I've been asked so many times how to start with Machine Learning or which course I have to join to learn it? But I have always the same reply - Machine Learning is a journey where you have to travel with a good friend (i.e. - Python, R, Java.....), face some obstacles (i.e. - Mathematical and Statistical Concepts...) and make more new friends there (i.e. lot of other things which you required to understand this ML world - Problem & its Domain, Algorithms, Comparison, tiring testing). So in simple words, ML is not a destination where you have to reach but its a journey which you have to live. Little dramatic... isn't it :-)

Anyway, Starting with very basic stats or statistics which you should be aware of with other ML things. Hoping, you will like it... Please comment if you have any query or request.

Use #UnlockStats to fetch all Stats post and #UnlockAI for all AI/ML posts.

ML-DL model as a Service - MLaaS

by Atul Singh / in #UnlockAI, Deep Learning, DL, Machine Learning, ML, Model, Publish, Rest, Service /

It is not always the case when we have to give or share the ML/DL model or algorithm with Client, sometime we want to allow users to use our model but without sharing the code or without setting up the infrastructure at Client end.

There is a way to achieve this, Convert your model as a Service, Yes, You can do that. You can expose your model as a Rest Service and user can use the method supported by your Service program. Today, we are going to learn the same.
Let's see how -

Tools Required -
Flask - A python web server
and of course Python :-)

ML/DL Model Creation:
For this part, I am picking very basic ML problem - IRIS dataset Classification.
Below code will create a Logistic Regression Classification Model and Save the model as a file.
==

Flask Web Server - REST Service
In below code, we are creating a REST service hosted on local system and having endpoint as "\iris" and Posting the array input to predict the IRIS species
==

How to run Flask Server:

Call ML Service: From Command Line:

Call ML Service: From Postman Client:

Learning Numpy #1

Numpy is a python library used for numerical calculations and this is better performant than pure python. In this notebook, I have shared some basics of Numpy and will share more in next few posts. I hope you find these useful.

My Learning Path for Machine Learning

by Atul Singh / in Analysis, Analytics, Code, data, github, IPython, Learning, Library, Machine, Machine Learning, ML, Pandas, Python, scikit-learn, Tutorial /

I am a Python Lover guy so my way includes lots of Python points. If you dont know the basics of this wonderful language, start it from HERE else you can follow the links which I am going to share.

Learning ML is not only studying ML algorithms, it includes Basic Algebra, Statistics, Algorithms, Programming and lot more. But no need to afraid as such :-) we need to start from somewhere.....

This is my github repo, you can fork it and follow me with these 2 links --

Fork - Fork
Follow - Follow @atulsingh0
I am still updating this list and welcome you to update this as well.

Learning Graphlab - SFrame #2

by Atul Singh / in Code, github, Graphlab, Learning, Machine, Machine Learning, ML, SFrame, Tutorial /

In last post Learning Graphlab - SFrame #1, we have learn basics of SFrame, like how to create, add or delete the columns in SFrame. In this post, we will revise it once again and learn some advance features of SFrame. Have a good learnng !!!

You can view the Jupyter Notebook for the same HERE

Learning Graphlab - SFrame #1

by Atul Singh / in Code, github, Graphlab, Learning, Machine, Machine Learning, ML, SFrame, Tutorial /

Hoping you guys went through the last post (Lnk -> Getting Started with Graphlab), In this post we will do some handson SFrame datatype of Graphlab which is same as dataframe of pandas python library.

i. Reading the CSV file
==
rdCSV

ii. save DataSet
==

iii. load DataSet
==

iv. Check Total Rows and Columns
==
rowNum

v. Check Columns data type and Name
==
colTypes

vi. Add new column
==
addCol

vii. Delete column
==

viii. Rename column
==
renameCol

ix. Column Swapping (location)

Getting Started with Graphlab - A Python library for Machine Learning

by Atul Singh / in Getting Started, Graphlab, Learning, Library, Machine, Machine Learning /

Before Starting with Graphlab, We have to configure our system with some basic tools such as Python, Jupyter Notebook etc. You can find 'How-To' on this link - http://bit.ly/2gvuG95

What is GraphLab ??

GraphLab Create is a Python library, backed by a C++ engine, for quickly building large-scale, high-performance data products. Some key features of GraphLab Create are:

Analyze terabyte scale data at interactive speeds, on your desktop.
A Single platform for tabular data, graphs, text, and images.
State of the art machine learning algorithms including deep learning, boosted trees, and factorization machines.
Run the same code on your laptop or in a distributed system, using a Hadoop Yarn or EC2 cluster.
Focus on tasks or machine learning with the flexible API.
Visualize data for exploration and production monitoring.

After the installation of Graphlab library we can use it as any python library.

Use Jupyter Notebook for starter, Open a Python notebook in Jupyter Notebook and execute below commands to see graphlab working -

a. Importing Graphlab -

==

b. Reading CSV file
This method will parse the input file and convert it into a SFrame variable

==

c. Getting Started with SFrame

i. View content of SFrame variable sf

==

ii. View Head lines (top lines)

==

ii. View Tail lines (last lines)
