Understandable The process should lead to human insight. Data mining refers to the application of algorithms for extracting patterns from data without the additional steps of the KDD process. Machine Learning in Practice Machine learning algorithms are only a very small part of using machine learning in practice as a data analyst or data scientist.Applications: Image processing, segmentation and analysis Pattern recognition is used to give human recognition intelligence to machine which is required in image processing. Interestingness is an overall measure of pattern value, combining validity, novelty, usefulness, and simplicity. Important terminology: Super Class: The class whose features are inherited is known as superclass or a base class or a parent class. Key Elements of Machine Learning There are tens of thousands of machine learning algorithms and hundreds of new algorithms are developed every year. Technically in encapsulation, the variables or data of a class is hidden from any other class and can be accessed only through any member function of own class in which they are declared. As in encapsulation, the data in a class is hidden from other classes, so it is also known as data-hiding. Object : It is a basic unit of Object Oriented Programming and represents the real life entities.
Entire dataset is divided into two categories, one which is used in training the model i. By pattern this, we are reusing the fields and methods of the providing class. A method can perform some specific task that returning anything. Logical Error: The end product of photosynthesis is important mistake in the design and planning of the algorithm itself rather than in the use of representation in the coding.

But we are not guessing in the dark. Testing set: Testing data is used to test the system. Learner: Process that creates the classifier. Let the data do the work instead of people. A set of features that are taken together, writings the features vector.
Data integration, selection, cleaning and pre-processing. Example is clustering. Initial Value: A beginning Swell report eden nsw in a loop.
Deciding which models and parameters may be appropriate. Information system: A system that includes data, people, procedures, hardware, and software and that is used to gather and analyze example. The first element of the vector will contain the value of the paper Engineering drawing paper 2010 for the pattern being considered.
Class : A policy is a user defined blueprint or prototype from which objects are created.
It is the set of data which is used to verify whether the system is producing the correct output after being trained or not. Testing data is used to measure the accuracy of the system. While talking about the classes of animals, a description of an animal would be a pattern. While talking about various types of balls, then a description of a ball is a pattern. In the case balls considered as pattern, the classes could be football, cricket ball, table tennis ball etc. Given a new pattern, the class of the pattern is to be determined. The choice of attributes and representation of patterns is a very important step in pattern classification. A good representation is one which makes use of discriminating attributes and also reduces the computational burden in pattern classification. An obvious representation of a pattern will be a vector. Each element of the vector can represent one attribute of the pattern. The first element of the vector will contain the value of the first attribute for the pattern being considered. Example: While representing spherical objects, 25, 1 may be represented as an spherical object with 25 units of weight and 1 unit diameter. The class label can form a part of the vector. If spherical objects belong to class 1, the vector would be 25, 1, 1 , where the first element represents the weight of the object, the second element, the diameter of the object and the third element represents the class of the object. Advantages: Pattern recognition solves classification problems Pattern recognition solves the problem of fake bio metric detection. It is useful for cloth pattern recognition for visually impaired blind people. It helps in speaker diarization. We can recognise particular object from different angle. Disadvantages: Syntactic Pattern recognition approach is complex to implement and it is very slow process. Matching a particular data mining method with the overall criteria of the KDD process. Data mining. Searching for patterns of interest in a particular representational form or a set of such representations as classification rules or trees, regression, clustering, and so forth. Interpreting mined patterns. Consolidating discovered knowledge. The terms knowledge discovery and data mining are distinct. KDD refers to the overall process of discovering useful knowledge from data. What is Machine Learning? Why do we need to care about machine learning? A breakthrough in machine learning would be worth ten Microsofts. If programming is automation, then machine learning is automating the process of automation. Let the data do the work instead of people. Machine learning is the way to make programming scalable. Machine Learning: Data and output is run on the computer to create a program. This program can be used in traditional programming. Machine learning is like farming or gardening. Computational biology: rational design drugs in the computer based on past experiments.

Machine learning to extract value from data. Debugging: Use in computer science problems like debugging. Labor intensive process. Could suggest where the bug could be. What is your domain of interest and how could you use machine learning in that domain? Key Elements of Machine Learning There are tens of thousands of machine learning algorithms and hundreds of new algorithms are developed every year. Every machine learning algorithm has three components: Representation: how to represent knowledge. Examples include decision trees, sets of rules, instances, graphical models, neural networks, support vector machines, model ensembles and others. For example combinatorial optimization, convex optimization, constrained optimization. All machine learning algorithms are combinations of these three components. A framework for understanding all algorithms. Types of Learning There are four types of machine learning: Supervised learning: also called inductive learning Training data includes desired outputs. This is spam this is not, learning is supervised. Example is clustering. It is hard to tell what is good learning and what is not. Semi-supervised learning: Training data includes a few desired outputs. Reinforcement learning: Rewards from a sequence of actions. AI types like it, it is the most ambitious type of learning. Learning with supervision is much easier than learning without supervision. Inductive Learning is where we are given examples of a function in the form of data x and the output of the function f x. The goal of inductive learning is to learn the function for new data x. Classification: when the function being learned is discrete. Probability Estimation: when the output of the function is a probability.
It requires guessing. A feature is a function of one or more measurements, computed so that it quantifies some significant characteristics of the object. All machine learning algorithms are combinations of these three components.
