Reinforcement Learning is a feedback-based Machine learning technique in which an agent learns to behave in an environment by performing the actions and seeing the results of actions. For each good action, the agent gets positive feedback, and for each bad action, the agent gets negative feedback or penalty.

In Reinforcement Learning, the agent learns automatically using feedbacks without any labeled data, unlike supervised learning.
Since there is no labeled data, so the agent is bound to learn by its experience only.
RL solves a specific type of problem where decision making is sequential, and the goal is long-term, such as game-playing, robotics, etc.
The agent interacts with the environment and explores it by itself. The primary goal of an agent in reinforcement learning is to improve the performance by getting the maximum positive rewards. terms: 
Agent(): An entity that can perceive/explore the environment and act upon it.
Environment(): A situation in which an agent is present or surrounded by. In RL, we assume the stochastic environment, which means it is random in nature.
Action(): Actions are the moves taken by an agent within the environment.
State(): State is a situation returned by the environment after each action taken by the agent.
Reward(): A feedback returned to the agent from the environment to evaluate the action of the agent.
Policy(): Policy is a strategy applied by the agent for the next action based on the current state.
Value(): It is expected long-term retuned with the discount factor and opposite to the short-term reward.
Q-value(): It is mostly similar to the value, but it takes one additional parameter as a current action (a).

What is communication (and what isn’t it)?
The P21 framework emphasizes effective use of oral, written, and nonverbal communication skills for multiple purposes (e.g., to inform, instruct, motivate, persuade, and share ideas). It also focuses on effective listening, using technology to communicate, and being able to evaluate the effectiveness of communication efforts—all within diverse contexts (adapted from P21). Note that working in partners is a great way to collaborate or build shared understanding but a critical part of communication is sharing with an authentic audience

School interventions should include a team approach across multiple settings, consisting of bothpreventive and intervention strategies. Interventions must be based upon assessment data that includes information about the student’s strengths and needs as well as the environmental conditions in which her characteristics of ADHD occur. Progress monitoring and strategy adjustments are critical to the success of any intervention plan (Wolraich & DuPaul, 2010).

Syntactic analysis or parsing or syntax analysis is the third phase of NLP. The purpose of this phase is to draw exact meaning, or you can say dictionary meaning from the text. Syntax analysis checks the text for meaningfulness comparing to the rules of formal grammar. For example, a sentence like “hot ice-cream” would be rejected by the semantic analyzer.
In this sense, syntactic analysis or parsing may be defined as the process of analyzing the strings of symbols in natural language conforming to the rules of formal grammar. The origin of the word ‘parsing’ is from the Latin word ‘pars’ which means ‘part’.
Concept of Parser
It is used to implement the task of parsing. It may be defined as the software component designed for taking input data (text) and giving a structural representation of the input after checking for correct syntax as per formal grammar. It also builds a data structure generally in the form of a parse tree or abstract syntax tree or other hierarchical structure.

SaaS is also known as "On-Demand Software". It is a software distribution model in which services are hosted by a cloud service provider. These services are available to end-users over the internet so, the end-users do not need to install any software on their devices to access these services.
There are the following services provided by SaaS providers -
Business Services - SaaS Provider provides various business services to start-up the business. The SaaS business services include ERP (Enterprise Resource Planning), CRM (Customer Relationship Management), billing, and sales.
 
Document Management - SaaS document management is a software application offered by a third party (SaaS providers) to create, manage, and track electronic documents.
Example: Slack, Samepage, Box, and Zoho Forms.
Social Networks - As we all know, social networking sites are used by the general public, so social networking service providers use SaaS for their convenience and handle the general public's information.
Mail Services - To handle the unpredictable number of users and load on e-mail services, many e-mail providers offering their services using SaaS.
 

The term cloud refers to a network or the internet. It is a technology that uses remote servers on the internet to store, manage, and access data online rather than local drives. The data can be anything such as files, images, documents, audio, video, and more.
There are the following operations that we can do using cloud computing:

Developing new applications and services
Storage, back up, and recovery of data
Hosting blogs and websites
Delivery of software on demand
Analysis of data
Streaming videos and audios

Virtual Working is on the rise and towards 2020 even more employees will demand flexibility in where and how they work. But which benefits and challenges does this bring to the workplace?

The ISS 2020 Vision: New Ways of Working – the workplace of the future respondents believe that virtual working will have the single greatest influence on office design, and the way we manage workplaces.

Unlike anything else, virtual working allows companies to offer their employees more flexibility and give them more control over their daily schedule. On the flip side of the coin research shows that managers are ill-prepared to manage virtual workers and struggle with coordinating remote employees.
So, is virtual working the right way to go for your business? We’ve listed the most important benefits and challenges associated with Virtual Working in our infographic below.

graphical user interface:
The graphical user interface (GUI  is a form of user interface that allows users to interact with electronic devices through graphical icons and audio indicators such as primary notation, instead of text-based user interfaces, typed command labels, or text navigation. GUIs were introduced in reaction to the perceived steep learning curve of command-line interfaces (CLIs), which require commands to be typed on a computer keyboard.
The actions in a GUI are usually performed through direct manipulation of the graphical elements. Beyond computers, GUIs are used in many handheld mobile devices such as MP3 players, portable media players, gaming devices, smartphones, and smaller household, office, and industrial controls. The term GUI tends not to be applied to other lower-display resolution types of interfaces, such as video games ), or not including flat screens, like volumetric displays.
User interface and interaction design:
Designing the visual composition and temporal behavior of a GUI is an important part of software application programming in the area of human-computer interaction. Its goal is to enhance the efficiency and ease of use for the underlying logical design of a stored program, a design discipline named usability. Methods of user-centered design are used to ensure that the visual language introduced in the design is well-tailored to the tasks.
The visible graphical interface features of an application are sometimes referred to as chrome or GUI (pronounced gooey) Typically, users interact with information by manipulating visual widgets that allow for interactions appropriate to the kind of data they hold. The widgets of a well-designed interface are selected to support the actions necessary to achieve the goals of users.
