While solving the classification problem statements using Deep Learning, we may come up with mainly the following two types of classification tasks:

Multi-Class Classification

Multi-Label Classification

As a short introduction, In multi-class classification, each input will have only one output class, but in multi-label classification, each input can have multi-output classes.

But these terms i.e, Multi-class and Multi-label classification can confuse even the intermediate developer. So, In this article, I have tried to give you a clear and easy intuition with examples of these terms in a detailed manner. If you are a Data Science Enthusiast, then read this article completely and accelerate your Data Science Journey.

What is Binary Classification?

In binary classification problem statements, any of the samples from the dataset takes only one label out of two classes.

For example, Let’s see an example of small data taken from amazon reviews data set.

                                                       Image Source: Link

If we carefully look into the table, we will see that we can only classify the review as either positive or negative i.e, only two possible target outcomes. So, this is an example of a binary classification problem statement.

What is Multi-Class Classification?

To understand multi-class classification, firstly we will understand what is meant by multi-class, and find the difference between multi-class and binary-class.

Multi-class vs. binary-class is the issue of the number of classes your classifier will be modeling. Theoretically, a binary classifier is much less complicated than a multi-class classifier, so it is essential to make this distinction.

For example, the Support Vector Machine (SVM) trivially can learn one hyperplane to split two classes, but 3 or more classes make it complex. In neural networks, we usually use the Sigmoid Activation Function for binary classification tasks while on the other hand, we use the Softmax activation function for multi-class as the last layer of the model.

For multi-class classification, we need the output of the deep learning model to always give exactly one class as the output class.

For example, If we are making an animal classifier that classifies between Dog, Rabbit, Cat, and Tiger, it makes sense only for one of these classes to be selected each time.

                                                       Image Source: Link

To ensure only one class is selected each time, we apply the Softmax Activation Function at the last layer and we use log loss to train the model.

Therefore, for a given dataset, any of the samples that come from the dataset takes only one label out of the number of classes. Let’s see an example of small data taken from the movies reviews dataset.

                                                     Image Source: Link    

If we carefully look into the table, we will see that we can only classify the movie rating from 2 to 5 i.e, each movie will have only one label (2, 3, 4, or 5). This means samples can have more than two possible target outcomes. So, this is an example of a multi-class classification problem statement.

What is Multi-Label Classification?

Multi-label vs. single-label is the matter of how many classes an object or example can belong to. In neural networks, when single-label is required, we use a single softmax layer as the last layer, learning a single probability distribution that ranges over all classes. In the case where multi-label classification is needed, we use multiple sigmoids on the last layer and thus learn a separate distribution for each class.

In certain problems, each input can have multiple, or even none, of the designated output classes. In these cases, we go for the multi-label classification problem approach.

For example, If we are building a model which predicts all the clothing articles a person is wearing, we can use a multi-label classification model since there can be more than one possible option at once.

                                                       Image Source: Link

Therefore, for a given dataset, any of the samples that come from the dataset takes more than one label out of the number of available classes. Let’s see a toy example.

Table Showing an Example of Multi-Label Classification Problem Statement

                                                 Image Source: Link

If we carefully look into the table, we will see that the movie may take more than one genre i.e, the movie could be comedy and Fantasy at the same time. This means samples can have more than two possible labels. So, this is an example of a multi-label classification problem statement.

Real-Life Example to Understand the Difference between Multi-Class and Multi-Label Classification

                                                 Image Source: Link

As you can know the general information that for any movie, the organization named Central Board of Film Certification, issues a certificate depending on the contents of the movie.

For example, if you look in the above image, then you may see that this movie has been rated as ‘U/A’ (meaning ‘Parental Guidance for children below the age of 12 years) certificate. This is not the only type of certificate but there are other types of certificates classes such as,

‘A’ (Restricted to adults), or

‘U’ (Unrestricted Public Exhibition),

but while categorizing the movies based on this, it is sure that each movie can only be categorized with only one out of those three types of certificates. In short, there are multiple categories (i.e, multiple certificates assigned to the movie) but each instance is assigned only one (i.e, each movie is assigned with only one certificate at once), therefore such problems are categorized under the multi-class classification problem statement.

Again, if you see carefully the image, then this movie has been categorized into the comedy and romance genres. But this time there is a difference that each of the movies can fall into one or more different sets of categories (i.e, have more than one genre). Therefore, each instance can be assigned with multiple categories (i.,e multiple genres), so these types of problems are categorized under the multi-label classification problem statement, where we have a set of target labels for each of the samples.

Great! after understanding this example properly, now you can easily distinguish between multi-label and multi-class problem statements. Congratulations on this! 😊

The Difference Between Learners And Students

As academic standards shift, as technology evolves, and as student habits change, schools are being forced to consider new ways of framing curriculum and engaging students in the classroom. Project-based learning is among the most successful and powerful of these possibilities.

As both a planning and a learning tool, PBL challenges teachers to make new decisions about how they plan student learning experiences, while simultaneously empowering students to take a more active role in the learning process.

In this context of trying to make sense of exactly what progressive learning was, in 2009 I sketched out a graphic that visualized 9 Characteristics of 21st Century Learning, and recently created a follow-up framework, the Inside-Out Learning Model.

The four primary goals of this model of learning are:

Authentic self-knowledge

Diverse local and global interdependence

Adaptive critical thinking

New media literacies

Secondary goals include: purposefully leveraging the diversity of digital media, evolving the traditional definition of project-based learning, the role of play in learning, curiosity, and individualized learning pathways that are digitally curated and transparent to all direct and indirect stakeholders.

In the Inside-Out Learning Model, the idea is personalized learning by new actuators, the elimination of passivity, and full integration with responsive and authentic communities — not coincidentally, these are also elements of PBL.

The Background

While watching all the ed reform trends come and go, one visual that has often intrigued me is a school that’s literally been turned inside out.

This thought first occurred to me as a second-year teacher in rural Kentucky, struggling to clarify to the parents how their son or daughter was performing in the classroom. I found the letter grades incredibly misleading. Learners that were really making strong progress and “learning a lot” would often bring home Cs, while many “A students” would be doing just enough for that A.

And even then, these alphanumeric icons were simply describing trends and compliance, and expressed very little about understanding even as I shifted towards standards-based grading. With letter grades, an A represents complete and total mastery of content, while a B represents above-average understanding, and/or near mastery of content. C means average, and the idea of being “average” was jarring to students, but more so to parents.

C was a death knell, and many times even students with a B had some ‘splainin to do, and few seemed to notice this as a problem. There was a need for parents in the classroom, while students needed to be out in the community.

Learners vs. Students

So then, we come to this idea about the difference between learners and students — there definitely seems to be one.

Students hopefully learn, but the word “student” connotes compliance and external form more than anything intrinsic or enduring.

You might notice the “C students” silently piecing together the learning process for themselves — internalizing it, throwing out what didn’t work, struggling in spots, but all the while becoming learners. They’d rarely question grades or ask, “What can I do for an A?” Instead, they’d focus on the interaction between themselves and the content.

This startling contrast was nearly impossible to clarify for parents when they wanted to know “what was going on.” As a teacher, I wanted a class full of learners, but the grading process was giving me a lot of students who were learning to play the game. The problem, however, was not as much about letter grades and traditional academia as it was about the “form” of the school.

What do I mean by the “form” of the school?

Its physical layout

Its tone, from extracurricular programs to academic reputation, certificates, credits, and downright monstrous notions of “achievement”

The relative lack of diversity of its sources for academic and instructional content

The internal audiences for school projects

And most of all, the need for real interdependence between that school and the community it was funded by and built to serve

To move from students to learners — well, there are probably dozens of ways to make a move like this, but somewhere on that list is using technology, project-based learning, and place-based education to truly turn a school inside-out.

The Difference Between Revenue And Income

A company’s revenue is the total amount of money it receives from sales over a set time period. Income is how much of that revenue is left after you deduct the business’s expenses. Subtract income from revenue and you’ll get the company’s cost of doing business over the time period measured.

Business owners need to understand the difference between net income and revenue (and measure both) because it helps them understand their expenses, including inventory costs, overhead and other outlays. It’s also important because businesses are valued differently using one number versus the other, and because only net income is taxable.

Editor’s note: Looking for the right accounting software for your business? Fill out the below questionnaire to have our vendor partners contact you about your needs.

What is income?

Income is the number reflected at the bottom of a cash flow statement. It represents the amount left over after a business accounts for revenue and expenses over the same period (i.e., all the money flowing into and out of the company). Income could be negative if a company’s expenses exceeded its revenue during the period in question. In that case, the company has operated at a loss.

Measuring a business’s net income starts with looking at its revenue – how much money the company brought in over a set time period. Then the company makes adjustments for all expenses incurred over the same period. Those expenses could include the following:

Cost of goods sold

Labor costs

Rent and utilities

Fixed overhead

Marketing costs

Legal fees

Office expenses

Salaries for office personnel

Employee benefit costs


Business licensing fees

Software subscription fees

While these are ordinary small business expenses, they don’t all apply to all companies. Applicable expenses for your business depend on its size, your company type, the industry you operate in, and your specific accounting practices.

Did You Know?

A company’s revenue can be negative, but only when returns exceed sales. So, while it’s theoretically possible, it’s improbable.

Examples of income vs. revenue

Different businesses use different measurements for both revenue and net income. Each figure includes varying factors and has a different level of relevance for a particular company based on its industry and how it operates.

Gross revenue is much more straightforward than net income. It’s the total amount of money that a business takes in over a specific time period. Here are some examples of gross revenue:

Total sales (this can be all goods sold in a quarter)

Total billable hours for an attorney or consultant

Gross licensing fees received

Total commissions received

Net income – the amount of money a company made or lost over a period of time after you offset expenses against revenue – is provided separately on accounting statements. It may appear on financial statements as any of the following:

Net operating revenue

Net income

Taxable income

Earnings before interest and taxes (EBIT)

Earnings before interest, taxes, depreciation and amortization (EBITDA)

Like revenue, a company’s net income is also easy to calculate using small business accounting software, but it’s more involved. A manager needs to generate a report that includes revenue and expenses, particularly those relevant to its specific operations. (Report generation is a typical accounting software feature.)

Once a manager produces a report reflecting some measure of net income (usually a profit and loss statement, or P&L), they still need to know which metric to use and how to use it. That’s one of the challenges of business accounting: Software can provide a lot of information, but it doesn’t tell business owners how to use these insights.

Importance of revenue vs. income in accounting

While a business’s net income includes more information about the overall state of its finances, both revenue and income are essential for small business owners to know, measure and track. These metrics are used for different things, but here are some of the common uses for both revenue and income:

Valuing a business

Raising capital

Getting a business loan

Calculating profit margin

Making important operational decisions

Both revenue and income are provided regularly in company financial reports to shareholders. Depending on a business’s type and size, these figures may also be included in reports filed with regulators such as the U.S. Securities and Exchange Commission.

Revenue and income are also prominent fixtures in tax forms filed with the IRS, as well as in company strategies for minimizing tax liability incurred from year to year.                        

Difference Between Blog And Website

Key Difference between Blog and Website

The main differences between Blog and Website are:

The Blog is usually informal, informative, and educated in nature, whereas A business website is formal and professional.

Blogs are dynamic in nature as the content keeps on regularly updating, while Websites are relatively static as changes only occur when some business strategy changes.

The basic unit of a blog is a post, whereas The basic unit of a website is content.

Blog vs Website

What is a Blog?

A Blog is an informational web page or a website published on the World Wide Web, consisting of independent and informative textual content on a particular subject. The information published on a blog is displayed in reverse chronological order so that the latest posts are displayed first. A blog is a platform where people share their views and have a discussion over a particular subject.

Blogging platforms are online publishing tools that are best for authors to publish articles, product reviews, and opinions. You can also share your blog post using stand-alone websites, social network feed syndication systems, and social networks.

What is a Website?

A website is a collection of webpages and multimedia content available under one domain on the World Wide Web. Websites are mostly hosted over web hosting services. It allows the web pages and the website’s content to be accessed over the World Wide Web. It is an internal site accessed through a secure local area network.

Websites are used for different purposes, like a business, personal blog, and even government agencies for information purposes. However, there is a broad range of applications. One main objective of creating a website is to provide information to visitors for a company or an organization.

Difference between Blog and Website

Here are some important differences between Blog and Website:

Subscription It allows you to subscribe to the blog’s RSS feed. On the website, no subscription is available to the RSS feed.

Brief History of Blogs

The term web blog was first introduced in the late 90s, which was also called ‘weblog,’ then ‘we blog,’ and nowadays, it is just ‘blog’.

Later on, because of the increasing number of web pages, various tools started to appear, which made it easier for users to build online blogs/articles or journals. These tools helped in easy blogging and made the technology easily accessible for even non-technical users.

In 1999, the first blogging platform chúng tôi launched its first separate blogging platform, which was later obtained by Google in February 2003. In that year, WordPress also released its first version as a blogging platform.

Brief history of Websites

Websites have been around for 25+ years, and it has come an exceptionally long way since its invention. CERN developed the first website in 1991, which was a complete text-based website.

However, with the first search engine development, ALIWEB, and the first landing page MTV, WWW became better and better. Later on, further enhancements of JavaScript for pop-ups and Flash for web animations were introduced. After that, people began to build more creative websites.

The first online eCommerce website was Amazon, which was developed in the year 1994. This opened the door for highly engaging and feature-rich websites. Today you will find thousands of eCommerce stores functioning over the Internet.

Difference Between Ddr2 And Ddr3

DDR stands for Double Data Rate. The DDR RAM is capable of transferring data on both edges, i.e. falling edge and rising edge of the clock pulse. Thus, it doubles the data transfer rate, hence it named so. The DDR RAM also comes in several versions (or generations), such as DDR, DDR2, DDR3, DDR4, etc. Each version/generation of the DDR RAM offers enhanced performance in terms of speed, storage capacity, energy efficiency, etc.

In this article, we will discuss the two generations, i.e., DDR2 and DDR3 of the DDR RAM, and the important differences between them.

What is DDR2?

DDR2, Double Data Rate 2, is a version of DDR RAM. DDR2 is basically an improved version of its predecessor, i.e. DDR. Therefore, DDR2 offers higher data transfer speeds (typically 400 to 800 Mbps) and enhanced performance. DDR2 version of DDR RAM was first introduced in the year of 2003. At that time, this was very commonly used in most desktops and laptops.

DDR2 RAM has a higher storage capacity and it consumes less power. Another improvement made in DDR2 in comparison to DDR RAM is its clock speed, which means DDR2 RAM operates at a relatively faster clock speed than DDR RAM.

These days, DDR2 RAM is not used or rarely used. However, this can be found in older computer systems only.

What is DDR3?

DDR3, Double Data Rate 3, is an enhanced version of the DDR2 RAM. DDR3 RAM offer more enhanced performance in terms of data transfer rates, power consumption, storage capacity, clock speeds, etc.

DDR3 RAM provides a higher data transfer rate than DDR2 RAM, typically 800 to 1600 Mbps, which is almost double of the DDR2 version. Also, it consumes less power than DDR2. Although, in terms performance, it is not better as the DDR2.

Being a new generation DDR RAM, DDR3 RAMs are most widely used in modern desktops and laptops.

Difference between DDR2 and DDR3

The following table highlights all the important differences between DDR2 and DDR3:





DDR2 stands for Double Data Rate Version 2.

DDR3 stands for Double Data Rate Version 3.


DDR2 is cheaper than DDR3.

DDR3 is costlier.

Data Transfer Rate

DDR2 provides 4 knowledge transfer per cycle.

DDR3 provides 8 knowledge transfer per cycle.

Supply Voltage

Supply voltage required is 1.8 volts.

Supply voltage required is 1.5 volts.

Memory Reset

No memory reset option is provided in DDR2.

Memory reset option is available in DDR3 RAM.

Clock Speed

Clock Speed ranges between 400 MHz to 800 MHz.

Clock Speed ranges between 800 MHz to 1600 MHz.

Power Efficiency

DDR2 consumes more power than DDR3. Hence, it is less power efficient.

DDR3 RAM is more power efficient, hence it consumes less power.

Heat Generation

DDR2 RAM generates more heat, hence it requires cooling to increase system stability.

DDR3 RAM generates less heat, reducing the requirement of cooling


DDR2 has narrower bandwidth due to its slower clock speed.

DDR3 RAM has wider bandwidth than DDR2 RAM.

Per Module Storage Capacity

DDR2 has lower per module storage capacity.

DDR3 RAM has per module storage capacity higher than DDR2 RAM.


DDR2 RAM offers better performance as compared to DDR3.

DDR3 RAM offers average performance.


DDR2 RAM can have latencies between 3 and 9 cycles.

DDR3 RAM has a latency of 9 or 10 cycles.

Launching Year

DDR2 RAM was launched in 2003.

DDR3 RAM was launched in 2007.


DDR2 RAM was used in older computer systems.

DDR3 RAM is used in modern computer systems.


Both DDR2 and DDR3 are the versions of DDR RAM used in personal computers and laptops. The most significant difference between DDR2 RAM and DDR3 RAM is in their data transfer speed. DDR2 RAM provides a slower data transfer speed, typically between 400 to 800 Mbps; while DDR3 RAM provides a faster data transfer speed which is about 800 to 1600 Mbps. However, DDR3 is more expensive than DDR2 RAM.

Difference Between Host And Hostess

One of the significant discussions that have been on the rise is whether the terms host and hostess can be used in place of each other. The word Jody generally has varied applications and makes distinguishing them challenging.

One example we can see here is event management, considered a professional work genre. Among the other delegates, the hosts play an essential role in the success of both big and small events. The host’s professionalism depends on the parties, and there are special training schools to establish oneself as the host or hostess.

However, when we take a deeper look at each of the applications, they may shed light on what each stands for, and the difference between the host and the hostess is not just limited to gender.

Who is a Host?

The word host is said to be an umbrella term that includes all activities that are attributed to the person hosting an event. Although the word host sub-categorization is male and female, a host is commonly attributed to a male person who indulges himself in hosting different activities. A good personality always acts as a plus point to a suitable host; the host is chosen based on skills like the entertaining nature, reliability of the content spoken, etc.

A host might be the guest at some parties, and vice versa. This interchangeability of the roles plays a vital role in maintaining a rapport and initiating friendly relations. The word host, when used as a verb, indicates the act of managing the party when the guests arrive. When used as a noun, the word host refers to a male host only who is expected to drive the events based on the agenda.

The term host has subjective interpretations as well, and it can take on different definitions based on the application like −

A host is someone who receives the guest and entertains them for commercial and other official purposes or socially.

A host might also be someone who facilitates a function or an event and provides facilitates for the same.
