Discuss the differences between dimensionality reduction based on aggregation and dimensionality reduction based on techniques such as PCA and SVD.

Following are the difference to this question can be defined as follows:

Explanation:

In terms of projections of information into a reduced dimension group, we can consider the dimension structure of PCA and SVD technologies.  In cases of a change in the length, based on consolidation, there's also a unit with dimensions. When we consider that the days have been aggregated by days or the trade of a commodity can be aggregated to both the area of the dimension, accumulation can be seen with a variance of dimension.

I’d say platform as a service (paas) or application platform as a service (apaas) or platform base service is a category of cloud computing services that provides a platform allowing customers to develop, run, and manage applications without the complexity of building and maintaining the infrastructure typically associated with developing and launching an app.

There’s also the option of making a new one
