Dimensionality Reduction Technique - Spark By {Examples}
In the field of machine learning, it is useful to apply a process called dimensionality reduction to highly dimensional data. The purpose of this process is to reduce the number of features under consideration, where each feature is a dimension that partly represents the objects. Why is dimensionality reduction … See more Machine learning is a type of artificial intelligence that enables computers to detect patterns and establish baseline behavior using algorithms that learn through training or observation. It can process and analyze … See more Clustering is the assignment of objects to homogeneous groups (called clusters) while making sure that objects in different groups are not … See more The strength of a successful algorithm based on data analysis lays in the combination of three building blocks. The first is the data itself, the second is data preparation—cleaning … See more A recent Hacker Intelligence Initiative (HII) research report from the Imperva Defense Center describes a new innovative approach to file security. This approach uses unsupervised machine learning to dynamically learn … See more WebWe do not always do or need dimensionality reduction prior clustering.

WebFirst, let’s talk about dimensionality reduction — which is not the same as quantization. Let’s say we have a high-dimensional vector, it has a dimensionality of 128. These values are 32-bit floats in the range of 0.0 -> 157.0 (our scope S). Through dimensionality reduction, we aim to produce another, lower-dimensionality vector.
