Top 8 Machine Learning Algorithms

Data Science Dojo

Support Vector Machines (SVM): This algorithm finds a hyperplane that best separates data points of different classes in high-dimensional space. Anomaly Detection Anomaly detection, like noticing a misspelled word in an essay, equips machine learning models to identify data points that deviate significantly from the norm.

Classification vs. Clustering

Pickl AI

ML algorithms fall into various categories which can be generally characterised as Regression, Clustering, and Classification. While Classification is an example of directed Machine Learning technique, Clustering is an unsupervised Machine Learning algorithm. What is Classification? Hence, the assumption causes a problem.

Use mobility data to derive insights using Amazon SageMaker geospatial capabilities

AWS Machine Learning Blog

It can represent a geographical area as a whole or it can represent an event associated with a geographical area. We can analyze activities by identifying stops made by the user or mobile device by clustering pings using ML models in Amazon SageMaker. Manually managing a DIY compute cluster is slow and expensive.

Anomaly detection in machine learning: Finding outliers for optimization of business functions

IBM Journey to AI blog

As organizations collect larger data sets with potential insights into business activity, detecting anomalous data, or outliers in these data sets, is essential in discovering inefficiencies, rare events, the root cause of issues, or opportunities for operational improvements. But what is an anomaly and why is detecting it important?
