Before we get to all the simple Machine Learning projects for beginners, let’s understand what ML really is. Artificial Intelligence and Machine Learning are quite the buzzwords today, especially with the widespread implementation of Big Data solutions (although ML has been around for many years before Big Data).

Machine Learning is a branch, or one form of application, of Artificial Intelligence which enables computational systems to learn from iterations and improve their functioning without any manual intervention.

In all essence, as the word describes, it allows a machine to ‘learn’, and with the vast amounts of data available today, learning can happen fairly quickly!

90% of the world’s current data was generated in the last 2 years!

To understand the concept of Machine Learning better, we can consider the example of one of the oldest and simplest forms of Machine Learning in existence, an email spam filter.

An email provider’s (such as Google) spam filter picks up on keywords embedded within emails that are being marked as spam around the world, in order to automatically mark similar emails as spam for the same and other users around the world.

It learns from users’ behavior to pick on what is spam, and what is not, so the user does not have to do it manually.

You can select simple machine learning projects for beginners, such as the following:

(a) Company level stock price predictor – A program that predicts a company’s price fluctuation for the next 6 months based on past data and quarterly reports.

(b) Error Forecasting – Build a model that studies predicted and actual price volatility to improve predictions, or predict anomalies.

(c) Arbitrage Opportunities – Analyse data of different stocks to group them based on similar price movements, to predict similar results.

As a caveat, do not actually invest real money based on your projects. These are just for study purposes.

The availability of large data sets makes this one the best projects on machine learning.

3. Analyze Social Media Sentiment Using Twitter Dataset

Social Media platforms are a massive array of data that can be mined and analyzed to predict outcomes and make accurate conclusions. One such prediction is social media sentiment. You can analyze different tweets around one topic or keyword to predict the current mood of masses towards that topic.

You can use the Twitter dataset to gather tweets and metadata like hashtags, retweets, locations, users, etc. for analysis. As a beginner project, you can start by classifying a topic into different sentiments: happy, sad, angry, etc. You can build on the same project to predict sentiment for a topic that is just beginning to trend.

4. BigMart Sales Predictor

You can acquire BigMart’s sales data set online (you can get a similar data set for Walmart and other companies to create similar projects on machine learning with them) that consists of data for over a thousand products from over 10 different outlets in different cities.

You can work on a beginner project to build a program that uses regression models to predict the sale of each product across each of the outlets based on historical data that is available.

Such predictive analytics are very much in demand as they help stores like BigMart control their inventory to prevent both shortage and wastage.

5. Healthcare Improvement Program

Machine learning is playing a big role in the healthcare industry today. Programs that help with predictive diagnosis, patient condition monitoring, proactive alerts, etc. are helping healthcare professionals work more efficiently.

You can apply your knowledge to work on the following sample machine learning projects:

(a) Outbreak Prevention – Study past disease outbreak data on a small scale (like a community) level to predict the outbreak of diseases. A simple example is to predict when members of a community are susceptible to the flu based on past data.

(b) Diagnostic Care – Study medical results and automatically classify them based on type.

(c) Insurance Corrections – Study risk factor based on past medical data to accurately adjust insurance premiums per individual.

6. Enron Scandal Analysis

If you have not heard of the Enron Scandal, do give it that article a read! Enron was one of the largest energy companies in America in 2000 when it was exposed to fraud which ultimately led to its bankruptcy and closure.

How the scandal helped ML engineers is that it gave us a rich database of over 500,000 emails between 150 former Enror senior executives.

This data is being used by programmers to build multiple machine learning projects, mainly because the emails are real making projects more challenging and accurate. You can use this data to build the following projects:

(a) Detect Anomalies – Build a program to analyze emails leading up to the scandal to identify anomalies that can be used to predict such instances in the future.

(b) Network Analysis – Build a program to map employe networks to identify the influencers of the scandal.

(c) Natural Learning Processing – Analyze behavior and language to classify emails into different categories, which can be used to predict future scandals.
