Hello, happy to see you here. Today let's dive into some popular topics which are often discussed in machine learning interviews. Without further ado, presenting to you the next cheat sheet. But what exactly do we do when we already have data? We will stop on each task separately in detail in next articles.

One model may make a wrong prediction. But if you combine the predictions of several models into one, you can make better predictions. This concept is called ensemble learning. Ensembles are methods that combine multiple models to build more powerful models. Ensemble methods have gained huge popularity during the last decade.

K Nearest Neighbors (KNN) is one useful supervised ML algorithm, generally used for classification problems but can be used for regression problems too. It is non-parametric algorithm, meaning the algorithm does no make any particular assumption about the kind of mapping function or the underlying data. For now, let us assume we are working on a binary classification problem and each observation in the data set (2-D) belongs to either positive class or negative class The main purpose of classification is given a point'xq', we have to predict the output value'yq'. Please note: There are various types of methods to calculate the distance between two points. I will try to cover them in a separate article later.

Are you a data scientist looking to develop a machine learning model? Use scikit learn to start creating your design today! Machine learning (ML), an application of Artificial Intelligence (AI), is rapidly growing at a faster rate. Almost every sector in today's world is adopting machine learning models as it brings value and improved customer experience resulting in higher Return on Investments (ROI). While many programming languages can help you get started with machine and deep learning, it is imperative to choose a programming language that is flexible and user-friendly.

This is Day 30 of the #100DaysOfPython challenge. This post will continue on from part one and break down the basics of linear regression and also explain how we can take the work that we did and expand upon that to apply a train-test split to our dataset. The packages required will be available in our conda environment. If you are unsure on how to activate the conda virtual environment, please look to the prerequisites or resources section for links on conda fundamentals. At this stage, the file docs/linear_regression.ipynb already exists and we can work off this material.

Today we will look at the parameters for AutoML for Scikit Learn and what each one means. This article could help you with deciding what to tune whenever you're using Auto ML for Scikit Learn.

Description This course introduces machine learning covering the three main techniques used in industry: regression, classification, and clustering. It is designed to be self-contained, easy to approach, and fast to assimilate.

This tutorial is on the basics of applying logistic regression, using a little bit of Python. It is also a continuation of the post "What is Linear Regression?", which can be found here. It is a little counterintuitive, but Logistic Regression is typically used as a classifier. In fact, Logistic Regression is one of the most used and well-known classification methods Data Scientists use. The idea behind this classification method is that the output will be between 0 and 1. Essentially returning the probability that the data you gave to the model, belongs to a certain group or class.

This course introduces machine learning covering the three main techniques used in industry: regression, classification, and clustering. It is designed to be self-contained, easy to approach, and fast to assimilate. The course is designed to maximize the learning experience for everyone and includes 50% theory and 50% hands-on practice. It includes labs with hands-on exercises and solutions. You can run the code on Google CoLab and get started right away.
