Types of Machine Learning

                            Machine Learning 

  • Machine Learning is an application of artificial intelligence where a computer/machine learns from the past experiences (input data) and makes future predictions. It finds the pattern in the data , based on the pattern it gives the future predictions from the unseen data.
  •  It is a way to understand the data and find the patterns in that.

Types of Machine Learning

 


 
 

 Supervised Machine Learning

  • An algorithm learns from example data and associated target responses that can consist of numeric values or string labels. 
  • Generally the algorithm should find the pattern how input and output is mapped

        Two types of Supervised Learning:

  • Regression: 
    • The problem is regression type when the output variable is real or continuous.
    • Example : 
      • Predicting salary of person based on past experience of person. 
      • Predicting house price based on house details. 
  • Classification:
    • A classification problem is when the output variable is a categorical. 
    • Example: 
      • Predicting incoming mail is spam or not spam. 
      • predicting whether loan should be accept or reject based on credit score of incoming loan application. 
  • Algorithms:
    • Linear Regression 
    • Logistic Regression 
    • k-Nearest Neighbor 
    • Support vector Machine
    • Decision Tress 
    • Ensemble Learning 
    • Naive Bayes Algorithm


Unsupervised Machine Learning

  • ML learns from unlabeled data set then it is unsupervised ML. 
  • The data set contain only inputs and no associated target responses. 
  • Algorithms: 
    • Clustering Algorithms 
    • Association clustering


Reinforcement Learning

  • Reinforcement learning is an area of Machine Learning. It is about taking suitable action to maximize reward in a particular situation. Reinforcement learning differs from the supervised learning in a way that in supervised learning the training data has the answer key with it so the model is trained with the correct answer itself whereas in reinforcement learning, there is no answer but the reinforcement agent decides what to do to perform the given task. In the absence of a training dataset, it is bound to learn from its experience.

Python Introduction

 Introduction  Python is developed by Guido Van Rossum and released in 1991. Python is high level, interpreted, general purpose programming language. It is one of the top five most used languages in the world. Currently there are 8.2 million developers who code in Python. Python is one of the most preferred languages in the field of Data Science and Artificial Intelligence. Key Features Python is an interpreted language, unlike compiled languages like Java, C, C++, C#, Go etc., Python codes are executed directly even before compiling.  Python is Dynamically typed, no need to mention type of variable before assigning. Python handles it without raising any error. Python codes can be executed on different software or operating systems without changing it. Python supports both Functional and Object oriented programming as it supports creating classes and objects. Python has high number of modules and frameworks support. Python is free and Open Source, which means it is availa...

Basic Concepts in time and work

                               Time and Work Time and Work is a another important concepts in aptitude. Pipes and cistern is an application of time and work. Time and Work is directly proportional , where if work increases, time also increases. Work and person is directly proportional, where if  work increases , persons also increases. Time and Person is inversely proportional , where if person increases ,time decreases. Formulas : If `A` completes work in `n` days , then the work completed in one day is 1/n th part of work. If `A` completes 1/n th work in one day, then total work completed in `n` days. Let us assume `A` completes the work in `n` days and `B` completes the work in `m` days .Let us take work as only one unit, the amount of work done in one day by `A` is 1/n similarly for `B` is 1/m. So in how many days the work is completed if they work together then ,A + B = 1/n + 1/m. Problem...

Importance of data preprocessing in machine learning

                          Data  Preprocessing Data Preprocessing is a technique that is used to convert the raw data into a clean data set. In other words, whenever the data is gathered from different sources it is collected in raw format which is not feasible for the analysis. Need of Data Preprocessing Inaccurate data There are many reasons for missing data such as data is not continuously collected, a mistake in data entry, technical problems with bio-metrics and much more. The presence of noisy data The reasons for the existence of noisy data could be a technological problem of gadget that gathers data, a human mistake during data entry and much more. Inconsistent data  The   presence of inconsistencies are due to the reasons such that existence of duplication within data, human data entry, containing mistakes in codes or names, i.e., violation of data constraints and much more. Steps Involved ...
