Data science is a way to try and discover hidden patterns in raw data. To achieve this goal, it makes use of several algorithms, machine learning(ML) principles, and scientific methods. The insights it retrieves from data lie in forms structured and unstructured. So in a way, this is like data mining. Data science encompasses all- data analysis, statistics, and machine learning. With more practices being labelled into data science. Text Analysis Statistical Analysis Diagnostic Analysis Predictive Analysis Prescriptive Analysis TEXT ANALYSIS:- Text Analysis is also referred to as Data Mining. It is a method to discover a pattern in large data sets using databases or data mining tools. It used to transform raw data into business information. Business Intelligence tools are present in the market which is used to take strategic business decisions. Overall it offers a way to extract and examine data and deriving patterns and finally interpretation of the data. Statistical Analysis It is use...

 What is Machine Learning? Machine learning is a growing technology which enables computers to learn automatically from past data. Machine learning uses various algorithms for building mathematical models and making predictions using historical data or information. Currently, it is being used for various tasks such as image recognition, speech recognition, email filtering, Facebook auto-tagging, recommender system, and many more. In the real world, we are surrounded by humans who can learn everything from their experiences with their learning capability, and we have computers or machines which work on our instructions. But can a machine also learn from experiences or past data like a human does? So here comes the role of  Machine Learning . How ML work with AI? Machine Learning is said as a subset of  artificial intelligence  that is mainly concerned with the development of algorithms which allow a computer to learn from the data and past experiences on their own. Th...

Scipy is the special library of python which is used to perform an advanced mathematical operation using the different predefined methods. It is the top layer of NumPy because NumPy is used to perform the basic mathematical operation , scipy mostly focus on l inear algebra and other a dvanced mathematical function . SCIPY was written as a SIGH PY word. How do we install scipy in the machine? if you want to install scipy with a core python or python shell then you can use the command python -m pip install scipy. pip install scipy Q)Create Script to write File in Matlab format and load it using scipy library? Matlab is a programming language that is a specialist in scientific programming. If we want to convert application data to Matlab format or Matlab format data to the application means we want to implement read and write operation then we can scipy library io module. 1) savemat():-  It is used to write application data to Matlab format 2) loadmat():-  It is used to read a...

Which programming language is best, after lockdown:- Corona is measure natural disasters in a world, we already know that our software development work is depended on the USA, Australia, Britain Country. We all know the USA share is about 80% in IT Industry hence Software development field will be definitely affected by COVID-19. It is 100% true. But you should never be feared with your career in IT, IT demands will be increased because now 70% of users will prefer online work for everything, it can be a new opportunity for IT students, learners, and Jobseeker. You should learn technologies in-depth only basic knowledge is not enough. Computer degree Btech ,  MCA is not enough for you .  You  should have good technical skills and expertise in any programming language . Many students satisfy with the current time and they are enjoyed ,  misused this time . it can harmful to your career ,  Enjoyment is best for happiness but if you want to groom in your career the...

  At a broad level, machine learning can be classified into three types: 1.   Supervised learning 2.   Unsupervised learning 3.   Reinforcement learning 1) Supervised Learning Supervised learning is a type of machine learning method in which we provide sample labeled data to the machine learning system in order to train it, and on that basis, it predicts the output. The system creates a model using labeled data to understand the datasets and learn about each data, once the training and processing are done then we test the model by providing a sample data to check whether it is predicting the exact output or not. The goal of supervised learning is to map input data with the output data. The supervised learning is based on supervision, and it is the same as when a student learns things in the supervision of the teacher. The example of supervised learning is  spam filtering . Supervised learning can be grouped further in two categories of algorithms...

Python is a high-level script-based language that contains the only interpreter to execute a python script. Script-based language means the language that will be executed by the  Interpreter. The interpreter will execute  the code line by lin e, Script-based language does not contain any separate compiler to convert the code. the compiler will be in-built under the interpreter. PHP,  PYTHON,  RUBY,  JS,  JQUERY,  ANGULAR,  NODE,  REACT all are script-based languages. Initially, a Python script was developed to create a device driver-based software system for the different operating systems. But now  Python is complete technology or platform which contain multiple library , framework, and support to create application softwar e. using Python script We can create the following application. 1 Desktop Application:-    This type of application will be installed separately on each machine. without using the internet this type ...
