Introduction to Machine Learning

Machine learning provides guidelines to computers to try to what comes naturally to humans, animals and provides instructions to find out from experience. Machine learning algorithms are used to learn the data and process it using computational methods. These algorithms are responsible to increase the performance of sample methods required for learning the computers.

Machine learning algorithms are responsible for finding natural patterns in data that generate insight and it will help you make better decisions and predictions. They are used a day to form critical decisions in diagnosis, stock trading, and energy load forecasting, and more.

Machine learning comes in 3 types:

Supervised learning- this is a basic type of machine learning. This algorithm is based on labeled data. This is the task-driven type of learning. The data must be labeled accurately for this method to work, this learning is very effective and powerful when used in the right conditions.

In this type of learning, a small part of bigger data is provided to Machine learning to work, called the training dataset. This training dataset gives an idea of learning to the algorithm.

Unsupervised machine learning- This algorithm can work on unlabeled data. This means that human labor isn't required to form the dataset machine-readable, allowing much larger datasets to be worked on by the program.

In supervised learning, the labels allow the algorithm to seek out the precise nature of the connection between any two data points. However, unsupervised learning doesn't have labels to figure off of, leading to the creation of hidden structures. Relationships between data points are perceived by the algorithm abstractly, with no input required from citizenry.

The creation of those hidden structures is what makes unsupervised learning algorithms versatile. Instead of an outlined and set problem statement, unsupervised learning algorithms can adapt to the info by dynamically changing hidden structures.

Reinforcement learning- directly takes inspiration from how citizenry learn from data in their lives. It features an algorithm that improves upon itself and learns from new situations employing a trial-and-error method. Favorable outputs are encouraged or ‘reinforced’, and non-favorable outputs are discouraged or ‘punished’.

Based on the psychological concept of conditioning, reinforcement learning works by putting the algorithm during a work environment with an interpreter and a gift system. In every iteration of the algorithm, the output result's given to the interpreter, which decides whether the result is favorable or not.

Applications of ML in today’s era:

* Computational finance

* Image processing and computer vision

* Computational biology

* Energy production

* Natural language processing

Railway Engineering: A Beginner’s Perspective – Introduction

Image
  The need of transportation was felt since the start of primitive civilization and with the human beings began shifting goods and people from one place to another. However this cumbersome task was done either as a head loads or in carts drawn by men or animals. However the advancement of civilization and progress in modern science and technology added new elements in the transportation systems such as steam powered engines followed by diesel or petrol and then electric powered engines. These stepwise new additions in to railway systems revolutionized transportation sector, which not only enhanced ease with which shifting of goods is done but also the volume of goods to be transported at longer distances within shorter times. Hence this system found superior to any other transpiration systems available. A rail system has proved to be a real vehicle for civilizational transformation and assimilation. Needless to say that one must learn more about the rail systems and its components. W

The Barsi Light Railway

Image
      The Barsi Light Railway between Latur and Miraj in Maharashtra was a pre-independence private company.) And set up a private company with a share capital of Rs. 7,014,477. The company's office was permanently located at Winchester House, Broad street, London. The Narrow-Gauge Railway, 2 feet 6 inches wide, was started on March 1, 1897, just 9 feet wide along Kurduwadi Barshi Road. The company's India office was initially located in Barshi and later in Kurduwadi. A. L. Alexander was appointed chief manager and agent. The duo of Alexander and Calthrop brought BLR a golden day by night. His salary was 2200 and 1500 rupees per month. Initially built only for Barshi Road (Kurduwadi) to Barshi, it grew to 323 km from Latur to Miraj in 1927, becoming the largest private narrow gauge railway in India. Due to the Warakaris going to Pandharpur, this vehicle was called the vehicle of God. Even on Ashadi Ekadashi, people used to sit not only on the train tracks but also in front of t

Indian Railways Toilet System

  Indian Railways serve 7,000 stations and 22 million passengers daily. Indian Railways commits to provide clients with safe and trustworthy train services, as well as clean and hygienic surroundings on trains and in stations. There are only 1600 long-distance trains. Suburban trains cover an average of 42 km. The remaining 4700 trains are estimated to be 3100 passenger trains traveling 50 to 250 km and 1600 mail/express trains operating 300 to 2400 km. Mail and fast trains are filthy. Both must be addressed. Even if we haven't done so, it would be fascinating to look at the train profile's duration and time (two or more nights or one night and arriving early in the morning) in terms of biological functioning and cultural norms. In the early days of the IR, lower-class train coaches had no bathrooms. On July 2, 1909, Babu Okhil Chandra Sen complained to Sahibganj [1]. Here's the letter Later, all lower-class trains traveling over 50 kilometers were expected to have ba
