The Process Behind Beginning to Work on a Machine Learning Project
You want to start working on a machine learning project-but what processes do you need to remember and how you will manage the data are the two crucial stages to begin working on any machine learning project. Choose a dataset and understand it to decipher as to which machine learning algorithm class or type can address the business problem in the best possible manner.
For machine learning beginners, our experts suggest that they start with a modest sized dataset that has been well studied before by experts. There are multiple libraries of data sources that have high-quality datasets such as – UCI ML Repository and Kaggle. Your goal before you begin any ML project should be to have an in-depth understanding of the problem that the data represents, the structure of the dataset and what all machine learning algorithms are best suited to solve the problem at hand. When studying the dataset , always use a statistical environment so that your focus remains on the questions you are looking to answer about the dataset instead of being distracted from a given technique and learning how to implement it in code. Some tips and tricks that can be of great help when studying and working with a machine learning dataset –
- Have a clear and in-depth understanding of the problem that the dataset represents.
- Always summarize the machine learning dataset using descriptive statistics.
- Make a note of the structures you observe in the data and put forward all the relationships observed in the data.
- Quickly test a couple of top machine learning algorithms on the dataset and find out which general class of algorithms has a better performance.
- Tune the algorithms to identify the algorithm that performs well for a given data problem and tune it accordingly.

Top 10 Machine Learning Projects for Beginners
We recommend these ten machine learning projects for professionals beginning their career in machine learning as they are a perfect blend of various types of challenges one may come across when working as a machine learning engineer or data scientist.
1) Iris Flowers Classification ML Project– Learn about Supervised Machine Learning Algorithms
Iris flowers dataset is one of the best dataset in classification literature. The classification of iris flowers machine learning project is often referred to as the “Hello World” of machine learning. The dataset has numeric attributes and beginners need to figure out on how to load and handle data. The iris dataset is small which easily fits into the memory and does not require any special transformations or scaling to begin with.
Iris Dataset can be downloaded from UCI ML Repository – Download Iris Flowers Dataset
The goal of this machine learning project is to classify the flowers into among the three species – virginica, setosa, or versicolor based on length and width of petals and sepals.
2) BigMart Sales Prediction ML Project – Learn about Unsupervised Machine Learning Algorithms
BigMart sales dataset consists of 2013 sales data for 1559 products across 10 different outlets in different cities. The goal of the BigMart sales prediction ML project is to build a regression model to predict the sales of each of 1559 products for the following year in each of the 10 different BigMart outlets. The BigMart sales dataset also consists of certain attributes for each product and store. This model helps BigMart understand the properties of products and stores that play an important role in increasing their overall sales.

3) Social Media Sentiment Analysis using Twitter Dataset
Social media platforms like Twitter, Facebook, YouTube, Reddit generate huge amounts of big data that can be mined in various ways to understand trends, public sentiments and opinions. Social media data today has become relevant for branding, marketing, and business as a whole. A sentiment analyser learns about various sentiments behind a “content piece” (could be IM, email, tweet or any other social media post) through machine learning and predicts the same using AI.Twitter data is considered as a definitive entry point for beginners to practice sentiment analysis machine learning problems. Using Twitter dataset, one can get captivating blend of tweet contents and other related metadata such as hashtags, retweets, location, users and more which pave way for insightful analysis. Twitter dataset consists of 31,962 tweets and is 3MB in size. Using Twitter data you can find out what the world is saying about a topic whether it is movies, sentiments about US elections or any other trending topic like predicting who would win the FIFA world cup 2018.Working with the twitter dataset will help you understand the challenges associated with social media data mining and also learn about classifiers in depth. The foremost problem that you can start working on as a beginner is to build a model to classify tweets as positive or negative.
4) Sales Forecasting using Walmart Dataset
Walmart dataset has sales data for 98 products across 45 outlets. The dataset contains sales per store, per department on weekly basis. The goal of this machine learning project is to forecast sales for each department in each outlet to help them make better data driven decisions for channel optimization and inventory planning. The challenging aspect of working with Walmart dataset is that it contains selected markdown events which affect sales and should be taken into consideration.

5) Learn to build Recommender Systems with Movielens Dataset
From Netflix to Hulu, the need to build an efficient movie recommender system has gain importance over time with increasing demand from modern consumers for customized content. One of the most popular dataset available on the web for beginners to learn building recommender systems is the Movielens Dataset which contains approximately 1,000,209 movie ratings of 3,900 movies made by 6,040 Movielens users. You can get started working with this dataset by building a world-cloud visualization of movie titles to build a movie recommender system.
6) Stock Prices Predictor
This is another interesting machine learning project idea for data scientists/machine learning engineers working or planning to work with finance domain. Stock prices predictor is a system that learns about the performance of a company and predicts future stock prices. The challenges associated in working with stock prices data is that it is very granular, and moreover there are different types of data like volatility indices, prices, global macroeconomic indicators, fundamental indicators , and more. One good thing about working with stock market data is that the financial markets have shorter feedback cycles making it easier for data experts to validate their predictions on new data. To begin working with stock market data, you can pick up a simple machine learning problem like predicting 6 month price movements based on fundamental indicators from an organizations’ quarterly report.You can download Stock Market datasets from Quandl.com or Quantopian.com.
7) Predicting Wine Quality using Wine Quality Dataset
I love everything that’s old, — old friends, old times, old manners, old books, old wine. — Oliver Goldsmith
It’s a known fact that older the wine, better the taste.
