How to Frame the Hypothesis for a Research Study?


How to Frame the Hypothesis for a Research Study?

Research hypothesis is a specific, clear and testable proposition or Hypothesis is basically possible assumption on the study result that can be obtained only on the completion of the study.

 
 
 
 

A research hypothesis is a proposed possible outcome of a research study which is written in the form of a testable predictive statement.This assumed stated outcome of the scientific research study is based on the attribute or variable of the population measuring the differences either between population and sample; two samples or relationships between variables.

 
A hypothesis stems from the research questions framed based on the research problem formulated. It focuses on relation between the set of variables of the study and therefore clarity on dependent and independent variable is crucial in hypothesis formulation.

Google Chrome 94’s Idle Detection


Google Chrome 94’s Idle Detection

Google has released Chrome 94 for desktop and Android and the browser comes a new controversial feature: the Idle Detection API.

 
 
 
 
 
As the name suggests, the “Idle Detection” API can detect user inactivity. The term Idle refers to the user who has not interacted with the device or its associated hardware, like the keyboard or the mouse, or through system events such as launching a screensaver or locking the system.

 

What is the Idle Detection API?

 
The Idle Detection API notifies developers when a user is idle indicating lack of interaction with the keyboard, mouse, screen, activation of a screensaver, locking of the screen, or switching to another screen. The notification is triggered based on user defined threshold.

The Idle detection API allows a Web application

River for Online Machine Learning in Python


River for Online Machine Learning in Python

River is a Python library for online machine learning. The library lets you train machine learning models on streaming data.

 
 
 
 
 

Introduction

 
All the traditional machine learning algorithms whether it is as simple as linear regression or strong learner algorithms like xgboost, all the algorithms process the data in batches. This means that these algorithms look at the complete dataset and fit the model. In case, there is new data available, it requires model fitting from scratch considering both; the new and old data.
 
There can be many challenges in re-training the model. Sometimes, it requires lot of memory to hold all the data which can affect training adversely and can make the process slower. In some other cases, it can be limited to the data

How to activate Compact OS feature in windows?

Compact OS lets you install the operating system files on your machine as compressed files. Compact OS is supported on both types of devices whether it is UEFI-based or BIOS-based.

 
 
 
 

Introduction

SSDs bring many advantages, not least a quicker startup, but rather their expense per gigabyte is as yet far higher than their hard drive partners. Subsequently, numerous people nowadays run Windows 10 from a little SSD or even MicroSD, leaving them barely adequate room to squeeze by. For the individuals who are truly battling, Compact OS can let loose space in Windows 10 without significant disadvantages.

Windows 10 and 11 comes along with features to save your disk space and optimize your image.

  • Compact OS allows you to run the operating system from compressed files.
  • Single-instancing
