clustering and association in unsupervised learning

Here in this article, we are going to look at Unsupervised Learning with respect to clustering. It aims to form clusters or groups using the data points in a dataset in such a way that there is high intra-cluster similarity and low inter-cluster similarity. Unsupervised learning is very important in the processing of multimedia content as clustering or partitioning of data in the absence of class labels is often a requirement. In some pattern recognition problems, the training data consists of a set of input vectors x without any corresponding target values. Clustering, Dimensionality Reduction, and Association Rule. Mining association rules between sets of items in large databases. So, what is Clustering exactly? Association rule learning is a method for discovering interesting relations between variables in large databases. In K-means clustering, data is grouped in terms of characteristics and similarities. Clustering. Grouping of simil a r data together is called as Clustering. There are three case in Unsupervised Learning. 1993. It mainly deals with finding a structure or pattern in a collection of uncategorized data. Proceedings of the 1993 ACM-SIGMOD International Conference on Management of Data, Washington, USA, 207–216 Google Scholar So both, clustering and association rule mining (ARM), are in the field of unsupervised machine learning. Source: Wikipedia. Clustering : grouping data based on similarity patterns. The main types of clustering in unsupervised machine learning include K-means, hierarchical clustering, Density-Based Spatial Clustering of Applications with Noise (DBSCAN), and Gaussian Mixtures Model (GMM). Unsupervised Learning: Clustering • Given: – Data Set D (training set) – Similarity/distance metet c/ o at oric/information • Find: – P titi i f d tPartitioning of data – Groups of similar/close items 2. In association rule learning, the algorithm will deep dive into large amounts of data and find some interesting relationships between attributes. Clustering Algorithms : K-means clustering algorithm – It is the simplest unsupervised learning algorithm that solves clustering problem.K-means algorithm partition n observations into k clusters where each observation belongs to the cluster with the nearest mean serving as a prototype of the cluster . Unsupervised learning problems further grouped into clustering and association problems. Types of Unsupervised Machine Learning Techniques. Clustering is an important concept when it comes to unsupervised learning. The main applications of unsupervised learning include clustering, visualization, dimensionality reduction, finding association rules, and anomaly detection. There are methods or algorithms that can be used in case clustering : K-Means Clustering, Affinity Propagation, Mean Shift, Spectral Clustering, Hierarchical Clustering, DBSCAN, ect.
