Algorithm of Principal Component Analysis (PCA)

The algorithm of Principal Component Analysis (PCA) is based on a few mathematical ideas namely Variance, Convariance, Eigen Vectors and Eigen values. The algorithm is of eight simple steps including preparing the data set, calculating the covariance matrix, eigen vectors and values, new feature set

Basic Ideas of Principal component analysis

Principal component analysis (PCA) is a technique to bring out strong patterns in a dataset by supressing variations. It is used to clean data sets to make it easy to explore and analyse. We have demonstrated an example of 17 dimensions and given the basic intuition of PCA

Popular Datasets in Machine Learning

Data sets are important in Machine learning as the more better data we have, the better the model. The various popular data sets available for machine learning are ImageNet, MNIST, NIST, CIFAR-10 and YouTube 8M.

Key ideas in TensorFlow

TensorFlow is a popular Deep Learning library that is used to build Deep Learning models and is backed by Google. A few key ideas of TensorFlow are tensor, distributed computing, kernel abstraction, operation abstraction, computational graph, automatic gradient computation and others

Differences between Torch and PyTorch deep learning libraries

We have explored some of the differences between two popular frameworks namely Torch and PyTorch from the view of common origin, current development status, source code and implementation, usage, performance and ONNX support. As development of Torch has been paused, you should go with PyTorch

OpenMP clauses: firstprivate, lastprivate, ordered

There are three basic OpenMP clauses namely firstprivate, lastprivate and ordered. firstprivate clause is used to initialize a variable from the serial part of the code and private clause doesn't initialize the variable

Basic OpenMP functions

There are 3 basic functions in OpenMP namely omp_get_thread_num, omp_set_num_threads (nthreads) and omp_get_num_threads. We have given a basic C/ C++ example to demonstrate the use of the function and the observation of the output as well

When to use OpenMP directives?

If some section of your code can be parallelized and you have more than one processor, you should definitely speed up the execution of your program using OpenMP directives. We have demonstrated how to use Amdahl's law to calculate the expected speed up and profiling to find which section takes time

Introduction to OpenMP

OpenMP is an open source library which is used for multi-threaded parallel processing and shared-memory multi-processor (core) computers. In OpenMP, part of program is a single thread and part is multi-threaded We have given advantages, disadvantages, industry use example, approach of OpenMP library
