K-Means Algorithm The unsupervised learning looks for previously undetected pattern/insight with minimum supervision in a dataset with no pre-existing labels such as unstructured data.K-means clustering is a type of unsupervised learning. The goal of K-means algorithm is to find groups in data, with the number of groups represent by the variable K.The algorithm works iteratively to…
Unsupervised Machine Learning: Social Network Analysis with Graph Analytics
Unsupervised Learning: Social Network Analysis with Graph Analytics A picture speaks a thousand words is one of the most commonly used phrases. But a graph speaks so much more than that. A visual representation of data, in the form of graph, helps us gain actionable insights and make better data driven decisions based on them.But to…
Unsupervised Machine Learning: Image compression using K-Means Cluster Algorithm
Image compression using K-Means Cluster Algorithm Most of us are used to working with structured data that fits neatly within fixed row and columns in relational database and spreadsheet as the examples. However, more than 90% of data generated today is considered unstructured, and this number will continue to rise with the prominence of Internet…
Supervised Machine Learning: Student Performance analysis using supervised learning algorithm
Python for Data Science: Unsupervised Learning Algorithm
In contrast to supervised learning that usually makes use of labelled data, unsupervised learning looks for previously undetected patterns in a data set with no pre-existing labels and with a minimum of human supervision. There are wide open implementation of unsupervised learning with unstructured big data which includes but not limited to areas such as: …
Python for Data Science: Supervised Learning Algorithm
The two techniques in Supervised Learning algorithms are: 1. Classification The algorithms which can be used in classification techniques include: Use Case: Titanic Data Set We will go through the process of creating Machine Learning model on the Titanic dataset from kaggle.com that predicts which passengers survived the Titanic shipwreck.The model will utilize all Classification Algorithms…
Python for Data Science: Machine Learning
What is Machine Learning? In essence, it is a type of Artificial Intelligence that extract patterns out of raw data by using an algorithm or method. The key focus of Machine Learning is to allow computer system to learn from experience without human intervention or being explicitly programmed.Two categories of Machine Learning are: Supervised Learning…
Race Report: 2019 Ironman Western Sydney
One fine evening in January 2021 and I am recovering from AC joint operation done a couple of weeks ago. No, I am not writing about how I ended up in operation theatre. Rather, I am writing about more colorful experience in Sydney, Australia in November 2019. I am way behind on posting this race report, which…
2019 Ironman 70.3 Asia Pacific Championship, Vietnam
2019 marks the 5th edition of Ironman 70.3 Vietnam and the venue of 2019 Ironman 70.3 Asia Pacific Championship. This year’s event featured special appearances of the Ironman World Champion, Patrick Lange from Germany, the Asia Pacific Champion Mauricio Mendez and the 2018 Ironman 70.3 Vietnam Champion Tim Reed on the starting line. It was truly a…
2017 Ironman 70.3 Bintan
This is my second Ironman 70.3 Bintan race in two consecutive years. I always have mix feelings about 70.3 Bintan race for it is an island paradise in itself providing picturesque beaches where the ocean floor is visible during the swim; a scenic landscape with lush, dense green forest and a few villages in its…
