== Introduction ==
Intel Data Analytics Acceleration Library, also known as Intel DAAL, is a library created by Intel in 2015 to solve problems associated with Big Dataand Machine Learning.<br/>Intel DAAL It is available for Linux, OS X and Windows platforms and it is available for works with the following programming languages: C++, Python, and Java programming platforms.<br/>Intel DAAL It is also optimized to run on a wide range of devices ranging from home computers to data centers and it uses Vectorization to deliver the best performances.<br/>
Intel DAAL helps speed big data analytics by providing highly optimized algorithmic building blocks for all data analysis stages and by supporting different processing modes.
== How Intel DAAL Works ==
Intel DAAL comes pre-bundled with Intel® Parallel Studio XE and Intel® SystemStudio. It is also available as a stand-alone version and can be installed following these instructions [https://software.intel.com/en-us/get-started-with-daal-for-linux instructions].<br/>
Intel DAAL is a simple and efficient solution to solve problems related to Big Data, Machine Learning, and Deep Learning.<br/>
The reasoning behind that is because it handles all the complex and tedious algorithms for you and software developers only have to worry about feeding the Data and follow the Data Analytics Ecosystem Flow.<br/>
Following, there are some pictures that show how Intel DAAL works in greater detail.

This picture shows the Intel DAAL Model(Data Management, Algorithms, and Services).
This model represents all the functionalities that Intel DAAL offers from grabbing the data to making a final decision.

A very good type of machine learning problem is handwritten digit recognition. Intel DAAL does a good job at solving this problem by providing several relevant application algorithms such as Support Vector Machine (SVM), Principal Component Analysis (PCA), Naïve Bayes, and Neural Networks. Below there is an example that uses SVM to solve this problem.
Recognition is essentially the prediction or inference stage in the machine learning pipeline.In simple words, When given a handwritten digit, the system should be able to recognize or infer what determine which digit was had been written. For In order for a system to be able to predict the output with a given inputset of data, it needs a trained model learned from the training data set that provides would provide the system with the capability to make an inference or a calculated prediction. The first step before constructing a training model is to collect training datafrom the given data within the .csv data set files
