Do you know? Initially the calculus of physics engines in video games was delegated to detecting collisions between in-game objects (such as player characters, rocks, and dust particles) and enacting appropriate responses. Similarly, Calculus is another important part of programming. Calculus problems show up practically all the time in machine learning. In any machine learning problem, the ultimate goal is to optimize the cost function.

As the technology is developing and seeing new inventions in various fields including machine learning, artificial intelligence, internet of things (IOT) and so on, there is an increase in the expectations in the consumer point of view. With the fast moving lives, the consumers absolutely have no time to stand in long queues in order to get their work done.
In this video, we can learn how to develop an Auto Billing Manager using, Tkinter; a standard GUI Library for Python. The App has also got automated teller system so as to automatically bill the products put into them and the final bill is sent to a printer for printout.
Automation, leveraging artificial intelligence (AI) and other technologies, has opened up new possibilities. The pace of adoption has been rapid. Institutions of all sizes globally are leveraging automation to drive value. Based on Statistics and Research, 57% of 1,300 institutions have already started on this journey, with another 18% planning to kick off something within the next phase.
When it comes to AI programming languages, Python leads the pack with its unparalleled community support and pre-built libraries (like Tkinter, NumPy, Pandas, Pybrain, and SciPy) that help expedite AI development
Artificial Intelligence is a way of making a computer, a computer-controlled robot, or a software think intelligently, in the similar manner the intelligent humans think.
The programming language is used globally to design and build 2D imaging software like Inkscape, GIMP, Paint Shop Pro, and Scribus. Also, Python is used in several 3D animation packages such as Blender, Houdini, 3ds Max, Maya, Cinema 4D, and Lightwave, to name a few.

mapping digital songs to authors/genres/song name,
mapping MRI scan data to medical diagnoses,
mapping Question’s answers to subjects/categories,
mapping internet clicks to advert suggestions.
Consequently, machine learning is now used also to find better representation of the input itself (this is called representation learning).

Teaching and learning and many opportunities for its application have yet to be explored. Spreadsheet software is one of the most-used technologies for collecting, computing, and displaying data. Spreadsheets contain a rectangular array of cells in rows and columns that can hold data. Users can create business models, graphs and charts, and reports for financial, statistical, or other data. Most spreadsheet software allows a user to access real-time data from Web sites and to collaborate across teams and workgroups.

Do you know? Sequence models are the machine learning models that input or output sequences of data. Sequential data includes text streams, audio clips, video clips, time-series data and etc. Recurrent Neural Networks (RNNs) is a popular algorithm used in sequence models. Applications of Sequence Models
Sequences are the main logical structure of algorithms or programs. When creating algorithms or programs, the instructions are presented in a specific correct order.
A sequence can contain any number of instructions but each instruction must be run in the order they are presented. For example, the interest portions of monthly payments made to pay off an automobile or home loan, and the list of maximum daily temperatures in one area for a month are sequences. Electronic and Electrical Engineers use the Fourier series to represent the properties of electrical signals

Do you know? Meteorologist uses Vectors to map out Weather Patterns….
Vectors are primarily used within the programming context of most programming languages and serve as data structure containers.
Being a data structure, vectors are used for storing objects and collections of objects in an organized structure.
Vectors can be used in softball to measure hits as well as pitches. When a ball is hit to the outfield, it has direction, speed, and distance.
The speed and direction of pitches can also be measured using vectors.

Do you know? Kinematics is used in astrophysics to describe the motion of celestial bodies and systems; and in mechanical engineering, robotics and biomechanics to describe the motion of systems composed of joined parts (such as an engine, a robotic arm, or the skeleton of the human body).
Motion of wheel, gears, motors, etc is rotational motion.
Motion of the blades of the helicopter is also rotatory motion.
Doors, swiveling on its hinges as you open or close it.
A spinning top, motion of a Ferris wheel in an amusement park
Understanding the kinematics of human movement is of both a basic and an applied value in medicine and biology.
Kinematic knowledge is also essential for proper diagnosis and surgical treatment of joint disease and the design of prosthetic devices to restore function.

Coding education and robotic applications are integrated or being integrated into education system for students at early ages all around the world. Consequently, the importance of coding education and robotic applications for achieving 21st-century and millennial goals cannot be over emphasized. A growing number of countries, in Europe and beyond, have established clear policies and frameworks for introducing computational thinking (CT) and computer programming to young children
Now, there is a need for students to acquire skills for producing solutions to problems, develop new ideas in an area of profession, human sciences and social sciences by using computer sciences and applications beginning from early childhood education. Middle school students playing video games are hardly news. But when the students are playing games they’ve built from “Scratch,” the story takes a turn.
