Interpolation can be used to impute missing data. Let’s see the formula and how to implement in Python. But, you need to be careful with this technique and try to really understand whether or not this is a valid choice for your data. Often, interpolation is applicable when the data is in a sequence or …

Machine Learning works on the idea of garbage in – garbage out. If you put in useless junk data to the machine learning algorithm, the results will also be, well, ‘junk’. The quality and consistency of results depend on the data provided. Missing values in data degrade the quality. Why clean the data before training …

Exploratory Data Analysis, simply referred to as EDA, is the step where you understand the data in detail. You understand each variable individually by calculating frequency counts, visualizing the distributions, etc. Also the relationships between the various combinations of the predictor and response variables by creating scatterplots, correlations, etc. EDA is typically part of every …
ML modeling is the step where machine learning is used to find patterns in data and use that learned knowledge to predict an outcome. The type of ML modeling we are going to solve in this problem is called ‘Churn Modeling’. Let’s first understand the Churn modeling problem statement and then go over the data …

Adaboost is one of the earliest implementations of the boosting algorithm. It forms the base of other boosting algorithms, like gradient boosting and XGBoost. This tutorial will take you through the math behind implementing this algorithm and also a practical example of using the scikit-learn Adaboost API. Contents: What is boosting? What is Adaboost? Algorithm …
Let’s understand how to define and formulate the machine learning problem (for predictive modeling) from a business problem. This structured approach should help you apply the process to most other types of predictive modeling problems at work. Introduction Often in ML teams, you will hear from the business/company departments about the problems and issues they …
Let’s build your first machine learning project with Python from scratch. “But I am a complete beginner, I am not ready yet!..” – Your mind voice. If you have been looking to get started in ML, but can’t really figure out how and where to start, then this one is for you. Just read on.. …
Python is the most popular programming language used for AI and machine learning. Let’s see how to setup python environment for ML using anaconda. How to install Python? Simply visit Python.org, go to downloads section, download latest version that shows there and install it like you do for any other software. To do machine learning …
The train-test split technique is a way of evaluating the performance of machine learning models. Whenever you build machine learning models, you will be training the model on a specific dataset (X and y). Once trained, you want to ensure the trained model is capable of performing well on the unseen test data as well. …
Today, I discuss the Data Science Roadmap, the missing guide to self study machine learning. I’ll discuss what exactly you need to know and do in order to self study Data science / ML / AI / Stats. I will provide you with some of the best resources for each topic, why you need to …

The use cases of machine learning to real world problems keeps growing as ML/AI sees increased adoption across industries. However, there are certain core use cases that add lot of value for organizations and you’ll often find them being implemented in banks, healthcare, manufacturing, product companies or by consulting organizations as well. Let’s tour of …
Not all Data Science projects that get kicked-off see the light of day. While this is true for any project, there are common reasons specific to Data Science projects, which can be avoided. These can either be prevented if you are aware and not commit these mistakes. Or if you see these problems, consider avoiding …
Let’s understand the formula for the linear regression coefficients. That is the formula for both alpha and the beta. Now, if you have simple linear regression that does, you have just 1x variable in your data, you will be able to compute the values of alpha and beta using this formula. Let’s suppose you …
Nebullvm is an open-source library that takes a deep learning model as input and outputs an optimized version that runs 5-20 times faster on your machine. Nebullvm tests multiple deep learning compilers to identify the best possible way to execute your model on your specific hardware, without impacting the accuracy of your model (GitHub link). …
Using ARIMA model, you can forecast a time series using the series past values. In this post, we build an optimal ARIMA model from scratch and extend it to Seasonal ARIMA (SARIMA) and SARIMAX models. You will also see how to build autoarima models in python ARIMA Model – Time Series Forecasting. Photo by Cerquiera …
