Introduction to Machine Learning in R

#artificialintelligence

This course material is aimed at people who are already familiar with ... What you'll learn This course is about the fundamental concepts of machine learning, facusing on neural networks. This topic is getting very hot nowadays because these learning algorithms can be used in several fields from software engineering to investment banking. Learning algorithms can recognize patterns which can help detect cancer for example. We may construct algorithms that can have a very good guess about stock prices movement in the market.


8 Clustering Algorithms in Machine Learning that All Data Scientists Should Know

#artificialintelligence

There are three different approaches to machine learning, depending on the data you have. You can go with supervised learning, semi-supervised learning, or unsupervised learning. In supervised learning you have labeled data, so you have outputs that you know for sure are the correct values for your inputs. That's like knowing car prices based on features like make, model, style, drivetrain, and other attributes. With semi-supervised learning, you have a large data set where some of the data is labeled but most of it isn't. This covers a large amount of real world data because it can be expensive to get an expert to label every data point.


12 Cool Data Science Projects Ideas for Beginners and Experts

Chatbots play a pivotal role for businesses as they can effortlessly handle a barrage of customer queries and messages without any slowdown. They have single-handedly reduced the customer service workload for us by automating a majority of the process. They do this by utilizing techniques backed with Artificial Intelligence, Machine Learning, and Data Science. Chatbots work by analyzing the input from the customer and replying with an appropriate mapped response. To train the chatbot, you can use Recurrent Neural Networks with the intents JSON dataset while the implementation can be handled using Python.


Image Segmentation Using Python Libraries and K-Means.

#artificialintelligence

We all are well aware of the capability of python libraries in machine learning, but you can also manipulate the image properties with the help of the matplotlib library. We will see how we can easily transform and manipulate image properties. We have imported the required libraries, Also cv2 is used to read and manipulate the image. Make sure that the image you want to manipulate lies in the same folder. As we know, image properties are generally in 3-dimension, it is very clear with the output we got (350, 525, 3).


Machine_Learning_with_Spark

#artificialintelligence

This is a comprehensive tutorial on using the Spark distributed machine learning framework to build a scalable ML data pipeline. I will cover the basic machine learning algorithms implemented in Spark MLlib library and through this tutorial, I will use the PySpark in python environment. Machine learning is getting popular in solving real-world problems in almost every business domain. It helps solve the problems using the data which is often unstructured, noisy, and in huge size. With the increase in data sizes and various sources of data, solving machine learning problems using standard techniques pose a big challenge.


Top 5 Clustering Algorithms Data Scientists should know

#artificialintelligence

Clustering Algorithms are essential aspects of Data Science and every data scientist must be aware of its concepts. Before discussing the top 5 clustering algorithms, we shall briefly see what clustering is and how it helps in Data Science. Clustering is a Machine Learning technique involving the grouping of data points. It is an unsupervised learning method and a famous technique for statistical data analysis. For a given set of data points, you can use clustering algorithms to classify these into specific groups.


KMeans clustering basics

#artificialintelligence

Clustering is part of an unsupervised algorithm in machine learning. Unlike supervised algorithms like linear regression, logistic regression, etc, clustering works with unlabeled data or data without target variables. The task of clustering is to group similar data points. Clustering comes under the data mining topic and there is a lot of research going on in this field and there exist many clustering algorithms. The following are the main types of clustering algorithms.


10 Machine Learning Algorithms You Need to Know

#artificialintelligence

If you've just started to explore the ways that machine learning can impact your business, the first questions you're likely to come across are what are all of the different types of machine learning algorithms, what are they good for, and which one should I choose for my project? This post will help you answer those questions. There are a few different ways to categorize machine learning algorithms. One way is based on what the training data looks like. Another way to classify algorithms--and one that's more practical from a business perspective--is to categorize them based on how they work and what kinds of problems they can solve, which is what we'll do here.


Top 5 Machine Learning Algorithms used by Data Scientists with Python: Part-1

#artificialintelligence

Machine learning is an important Artificial Intelligence technique that can perform a task effectively by learning through experience. According to Forbes, machine learning will replace 25% of the jobs within the next 10 years. One of the most popular real-world applications of Machine Learning is classification. It corresponds to a task that occurs commonly in everyday life. For example, a hospital may want to classify medical patients into those who are at high, medium or low risk of acquiring a certain illness, an opinion polling company may wish to classify people interviewed into those who are likely to vote for each of several political parties or are undecided, or we may wish to classify a student project as distinction, merit, pass or fail.


What is the KMeans Clustering Algorithm and How is it Used to Analyze Data? - DATAVERSITY

Click to learn more about author Kartik Patel. This article provides a brief explanation of the KMeans Clustering algorithm. The KMeans Clustering algorithm is a process by which objects are classified into number of groups so that they are as much dissimilar as possible from one group to another, and as much similar as possible within each group. KMeans Clustering is a grouping of similar things or data. For example, objects within group 1 (cluster 1) shown in image below should be as similar as possible.
