Artificial intelligence (AI) is the field of computer science dedicated to solving cognitive problems commonly associated with human intelligence such as problem solving, learning and pattern recognition. Machine Learning (ML) and Deep Learning (DL) are both computer science fields that are derived from the discipline of Artificial Intelligence. Machine learning describes the ability of a machine to learn the things such as language, behavior, patterns and habits without having been programmed to do so, or preloaded with that knowledge. Deep learning is designed to imitate the way human brain works. It involves training the artificial neural networks to comprehend data based on certain criteria. Example of machine learning in practice is Image Recognition in which neural networks are able to recognize different data patterns to learn, what, for example, a fish looks like.
AI becomes smarter and learns faster with more data, and businesses worldwide are fueling their growth leveraging machine learning and deep learning solutions.
The ability to build and leverage applications that learn on their own is a powerful idea. The challenges related to building sophisticated AI systems center mostly around scale as the databases are massive, training can be computationally challenging and inferring predictions can be hard.
How Amazon rebuilt itself around AI
Amazon is no stranger to AI Services. It was one of the pioneers to use the technology to drive its product recommendations. Amazon AI is Amazon Web Services (AWS) deeply customizable machine learning and AI platform. It is designed to be scalable to match an enterprise’s specific needs. Amazon AI is structured in three layers at services level.
These are:
- Amazon Rekognition
- Amazon Polly
- Amazon Lex
These APIs are pre-trained and pre-tuned so that these can be used by the developers with little to no AI expertise.
At the platform level, AWS supports deep learning engines such as Apache MXNet, pyTorch, TensorFlow, Caffe/Caffe2 and others.
One layer lower are AI platforms which are:
Amazon Machine Learning: It contains a series of visualization tools to analyze data without the need to learn complex machine learning tools.
Amazon Elastic MapReduce (EMR): It’s a managed Hadoop framework which is designed to perform real-time analytics, log analysis, predictive analytics and other data operations.
Spark: It’s an Apache product that runs inside of Amazon AI as a distributed processing system for big data workloads.
Below that are the AI frameworks, all of which run as part of the Amazon Deep Learning. The AI framework level is a basic Linux environment with the required tools to do AI and machine learning work. It is also the most development intensive of the three frameworks.

Machine learning adding value to predictive analytics
Machine learning helps to improve the efficiency and effectiveness of business processes.
Data analysts are increasingly using machine learning techniques for predictive analytics as they tend to outperform statistical techniques for prediction problems. Potential applications of AI for predictions in business operations are broad and deep. Machine learning produces more accurate results when the behavior you want to predict is rare and the data sets have large number of varying features. ML algorithms tend to scale well with large volumes of data.
With cheap storage solutions, businesses looking to make better use of data can keep the data they used to discard. Machine learning helps the data analysts identify patterns in this data too.
Breadth of functionality
Businesses benefit from the continual evolution, innovation and iteration as they stand to access the newest features and enhancements instantly. They need not upgrade, deploy or mitigate.
Elasticity
Enterprises often overprovision to ensure that they had enough capacity to efficiently handle their business operations at the peak levels of demand. Implementation of artificial intelligence capabilities will allow them to provision the amount of resources that they actually need knowing that they can easily scale up or down as per the demand. This not only helps in reducing costs but also enhances an organization’s ability to meet the demands of its customers instantly.
How to get started with Amazon AI?
Anyone with AWS account can begin using the service after making payment. It’s charged on per-use basis, so costs should be negligible for basic use.
