Neural Networks – Placement of categorization and semantic mapping on a mobile robot

I am currently working on a project where I have to create a semantic map of the environment through which my robot moves. An RGB-D camera is mounted on the robot. So, as it moves through the environment, it can perceive a continuous stream of images, each directed through a CNN trained to identify various locations such as kitchen, elevator, corridor, door, etc., and the result the location classification is then iterated through a Bayesian filter to create an occupancy grid map of the environment that is labeled with different location categories (colors corresponding to different locations) as described in this document. An example is shown below:

Enter image description here

Now the problem is here, if you look at yourself Point X Although the robot is in the corridor at this time, the camera already recognizes an office (orange) and therefore identifies part of the corridor as an office.

I am looking for a solution to circumvent this and segment the map as accurately as possible in real time as the robot moves through the environment. This can also be done iteratively, z. For example, to refine the result when the robot crosses point X again sometime in the future.

P.S. The robot is also equipped with two laser rangefinders to create the occupancy map. Maybe I can somehow combine the laser range point cloud with the depth point cloud of the RGB D camera.

To create a semantic / accessible list using the Load More button

Here is a simple example of what I would like to do:


  • Item 1
  • Item 2
  • Item 3


// Pseudo code

Logically, it's a bit simple and it would work well with the keyboard. I'm not sure how to make this feature more accessible to screen readers, so I'll be alerted when new items are added to the list.

Does anyone have an option / kickstart how to do that?

I did not find anything in my search. Maybe I'm looking for the wrong keyword.

Thanks a lot!

seo – Semantic Markup itemprop Name / Description on multilingual website

I'd like to set up a semantic markup for products such as a language stay on a site that's available in fr, en, and it languages.

I wonder if I can have the name of the product and its description in its three languages! Example:

The page in French:


The same page in English:


Is it possible to have the name and description of a product in multiple languages ​​because they have the same unique itemprop / mpn code? Is it good for SEO or not recommended?

Thank you for your advice,

Semantic Versioning – How Does a Software Developer Perform Two Minor Updates Simultaneously?

In a web application I'm just creating, two smaller functions might be running at the same time: implementing a new web page and implementing the notification bar. After merging both in Master on GitHub and resolving existing conflicts, I'll release them.

My current version is v0.9.1

When I release it again, there are two new minor changes. Would it be 0.11.0, 0.10.0? The seems to give no insight into this scenario.

Note: I would ask this on webapps SE, but the semantic versioning does not have its own tag. It seemed more likely to get an answer on this page.

Semantic Web – When should the "mentions" property of be used for what kind of references?

The mentions Property can be used on Creative workSo everyone items and website, The value for this property is thing,

This gives the webmasters very comprehensive possibilities. In theory mentions should be used very often, but it is not really. Why? Do I misunderstand the definition of

Indicates that CreativeWork has a reference to a concept but does not necessarily refer to it.

Anytime the content of a web page contains a link to another web site or digital document on my server that can serve as a "reference" I can use it mentions Property, could not I? For example, I mention some references for my work on my aboutme page, may be a digital document (.jpg, .pdf, etc.) of my last course or an article about me on a website of the authority ect.

is mentions really the all-purpose weapon that I take or use better Quote Property for my purposes?

Version Control – Categorize configuration changes in semantic commit messages

I'm trying to switch to semantic commit messages for the project. Although the idea is good, sometimes I find it difficult to properly categorize changes like a configuration value change.

Which type is appropriate when I commit a change to a database password or increase the size of a worker pool? Is it a bothersome. fix or a Refactor? Should I determine the type based on the changes, or why was the change required?

Web Development – Why Create CSS Classes That Match a Specific Style? (not semantic class names)

There are a number of CSS frameworks that have a one-to-one correspondence between many classes and a single style. For example, in bass, ".inline-block" is called "display: inline-block;" Are defined.

What is the use of creating a class that matches a particular style?

The use of such classes could be replaced by an inline style, and there would be no difference in maintainability.

Is not this incompatible with the point of a "class" (ie classification which is a "systematic arrangement in groups or categories")? Yes, you can form a group of numbers that are number 3 … but that rarely makes sense.

Just to be clear, not all classes in bootstrap and basscss are semantically significant. For example, "rounded" in Basscss describes a style (border radius: 3px;) that can be globally changed to accommodate new designs (for example, 4px).

Is this just to reduce the input (in case of "mb0" for "margin-bottom: 0") or to reduce the file size at the expense of clarity?

HTML 5 Semantic Mark-Up

Hello everybody,

There are so many great tutorials on the Web that teach HTML / HTML 5 from Basic to Advanced. However, most of these tutorials just show you what the tags are basically.

I have not found a resource that will teach you to tag content with semantic meaning. I know it's not rocket science, but I'm worried about how to balance semantic markups, keeping SEO principles in mind.

Does anyone have any good sharing / webpage resources, or could he explain some examples below and share your thoughts? Thank you in advance!

Would this example be semantically correct? If not why? and how does the content come into the picture?

Matthew West

Matthew Joseph West[1] (Born April 25, 1977) is an American contemporary Christian musician, singer-songwriter and actor. He has released five studio albums and is known for his songs "More", "You Are Everything" and "The Motions". He was nominated for five Dove Awards in 2005, two of which were for his major label debut album Happy. West was honored in 2013 with the American Music Award for Best Contemporary Artist.[2]

He began as an independent musician in the late 1990s and released three independent albums before signing with Universal South Records. With the release of his Dove Award-winning debut album Happy, released in 2003, his first radio single, "More," remained # 1 in Christian Adult Contemporary's charts for nine weeks and received two nominations for the Dove Award. On his second album, History, followed in 2006, the re-release of the originally independent album Sellout.

In addition to his solo career, West has worked as a songwriter for many Christian musicians and groups such as Point of Grace, Mandisa, Natalie Grant and Casting Crowns as well as for mainstream country acts such as Rascal Flatts, Billy Ray Cyrus and Vince Gill.

Early life

Matthew West was born on April 25, 1977, in Downers Grove, Illinois.[5][6] As a kid, he was a fan of his hometown baseball team, the Chicago Cubs, and eventually wanted to have a career in baseball.

West wrote most of his first songs in the sanctuary of his father's church while he was at home during college breaks.[7] According to a statement by West at Winter Jam 2013 (March 23, 2013): At a 1997 Steven Curtis Chapman concert in the Aula in Champaign, Urbana, West said he had cried violently and asked his friends what it is wrong.

Shortly before graduating from Millikin University in 1999, someone from College West recommended attending GMA Music in the Rockies for prospective musicians. Although West was not initially interested, he took part after learning that others had registered and paid his entry fee.

Musical career

On the 26th of July 2002[8] Just a week or two before signing a record deal with Universal South Records, West had a left arm injury that threatened his musical career and guitar playing. He says, "I locked myself out of my house, but I had done that before, and I had a chance to break in through a window, but this time I had a hard time opening the window.

I started to push myself against the window and my hand broke through the glass. Blood was spilling out of my left arm everywhere and I ran down the street screaming for help. After seeing so much blood, I got a shock and turned black in the middle of the road.


Web Application – Semantic URL Attack Mitigation

updateprofile.php? i can change uid = 1

updateprofile.php? uid = 2

If you can change the uid parameter and then customize other people's profiles, the backend application will not have a check to see if a user has permission to take action.

This attack can be a combination or one of the following (incorrect session management, url manipulation, indirect object reference, parameter manipulation)

How can I prevent this type of attack? By using session variables?
Do you encrypt the data via the URL?

Yes, SESSIONS in combination with logical checks are the way to solve such attacks.

I'm sure sessions are vulnerable to XSS or session hijacking attacks.

SESSIONS have nothing to do with XSS.

What is the best approach for this? Coding approach etc.

The coding approach is to use SESSION tokens to uniquely identify a user. Then, server-side checks are performed to determine if a user is authorized to perform an action, such as editing a profile.
