![APPLICATIONS
Machine learning enables organisations to
analyze complex data automatically at scale and
with tremendous accuracy. It gives organisations
the insight they need to make data-driven
decisions about their operations.
However, machine learning algorithms need to be
taught and trained[AC1] to deliver this insight.
For example, when exposed to a large data set,
the machine can detect patterns and use historical
and real-time data to determine the best course of
action or procedure that will deliver the
best result in the shortest possible time.](https://image.slidesharecdn.com/machinelearning-190321014409/85/Machine-learning-6-320.jpg)

It focuses primarily on the study and construction of algorithms that can learn and make predictions based on data, as well as overcome program limitations and make data- driven decisions. The term ‘machine learning’ was initially coined by Arthur Samuel in 1959 and is defined as a “computer’s ability to learn without being explicitly programmed”. Machine learning has grown in popularity since then – and we have arrived at the point where it is profitable and possible for businesses to utilise machine learning to improve efficiency. Machine learning was born from pattern recognition and the notion that computers can learn without being programmed to perform specific tasks. In helping machines to learn without being programmed to do so, the machine can adapt and improve over time. By using algorithms, machines can learn – and different algorithms learn in different ways. As machine learning algorithms are exposed to new data sets they adapt over time and increase their ‘intelligence’. WHAT IS MACHINE LEARNING?
- 3. WHY MACHINE LEARNING? Machine learning is an application of artificial intelligence (AI) that provides systems the ability to automatically learn and improve from experience without being explicitly programmed. Machine learning focuses on the development of computer programs that can access data and use it learn for themselves. The process of learning begins with observations or data, such as examples, direct experience, or instruction, in order to look for patterns in data and make better decisions in the future based on the examples that we provide. The primary aim is to allow the computers learn automatically without human intervention or assistance and adjust actions accordingly.
- 4. Machine learning uses two types of techniques: supervised learning, which trains a model on known input and output data so that it can predict future outputs, and unsupervised learning, which finds hidden patterns or intrinsic structures in input data. HOW MACHINE LEARNING WORKS? Supervised Learning: It builds a model that makes predictions based on evidence in the presence of uncertainty. A supervised learning algorithm takes a known set of input data and known responses to the data (output) and trains a model to generate reasonable predictions for the response to new data. Use supervised learning if you have known data for the output you are trying to predict. Supervised learning uses classification and regression techniques to develop predictive models.
- 5. Unsupervised learning :It finds hidden patterns or intrinsic structures in data. It is used to draw inferences from datasets consisting of input data without labeled responses. Clustering is the most common unsupervised learning technique. It is used for exploratory data analysis to find hidden patterns or groupings in data. Applications for cluster analysis include gene sequence analysis, market research, and object recognition. For example, if a cell phone company wants optimize the locations where they build cell phone towers, they can use machine learning to estimate the number of clusters of people relying on their towers. A phone can only talk to one tower at a time, so the team uses clustering algorithms to design the best placement of cell towers to optimize signal reception for groups, or clusters, of their customers.
