Artificial neural network
An artificial neural network is an interconnected group of nodes, akin to the vast network of neurons in a brain. Here, each circular node represents an artificial neuron and an arrow represents a connection from the output of one neuron to the input of another. For example, a neural network for handwriting recognition is defined by a set of input neurons which may be activated by the pixels of an input image. After being weighted and transformed by a function (determined by the network's designer), the activations of these neurons are then passed on to other neurons.
Gunk (mereology)
In mereology, an area of philosophical logic, the term gunk applies to any whole whose parts all have further proper parts. That is, a gunky object is not made of indivisible atoms: If something is made of atomless gunk then it divides forever into smaller and smaller parts—it is infinitely divisible. However, a line segment is infinitely divisible, and yet has atomic parts: the points.
Pearltrees releases a new version, without any pearls nor trees
The Paris-based startup founded in 2009 once declared: “We focus on the visual potential of Pearltrees to let people dive deeply into their interests and nearly feel them”. Their product, offering a digital curation tool, was unique because of the visual interface voluntareely original: links and folders symbolized by rounded pearls attached together like the branches of a tree. Today, pearls and trees have disappeared to make room for a brand new and larger organisation tool. Two years ago, everyone wanted to build products around “curation” and “interest graph”. Today the keywords have shifted to “collaborative SaaS tool” and “organizing data”.
Pearltrees 2.0 Launches with a Brand New User Interface
Today Pearltrees officially separated itself from its unique visual interface made of pearls and pearltrees, finally succumbing to the trend of Pinterest-like user experience. It might be more practical for the majority of users to sort and collect content with the new Pearltrees 2.0, however, some people might regret the innovative former interface that allowed to discover related content rapidly by browsing an “ocean” of Pearls. Users still have the possibility to go back to the “pearly” version accessible from the menu in the settings section. Now the Pearltree has been replaced by the “Collection” which is basically a “folder” (or a board) containing various types of content of a topic, for instance, you can collect web pages, images, and notes, just like you can do with Evernote and Pinterest. Unlike Evernote, you are able to browse the public content collected by other users, and if you feel the need to make your content private, the premium version offers the feature.
Pearltrees
Pearltrees refers to itself as "a place for your interests".[8] Functionally the product is a visual and collaborative curation tool[9][10][11][12] that allows users to organize, explore and share any URL they find online as well as to upload personal photos, files and notes.[13] The product features a unique visual interface[14][15] that allows users to drag and organize collected URLs, and other digital objects.[16] that themselves can be further organized into collections and sub-collections,[17] (URLs). Users of the product can also engage in social/collaborative curation using a feature called Pearltrees Teams.[18] Pearltrees was founded by Patrice Lamothe, CEO,[22] Alain Cohen, CTO,[23] Nicolas Cynober, Technical Director,[24] Samuel Tissier, Ergonomy/UI[25] and Francois Rocaboy, CMO.[26] History[edit] Development of Pearltrees began in 2007.
Neural Network Package Torch7
This package provides an easy way to build and train simple or complex neural networks. Each module of a network is composed of Modules and there are several sub-classes of Module available: container classes like Sequential, Parallel and Concat , which can contain simple layers like Linear, Mean, Max and Reshape, as well as convolutional layers, and transfer functions like Tanh. Loss functions are implemented as sub-classes of Criterion. They are helpful to train neural network on classical tasks. Common criterions are the Mean Squared Error criterion implemented in MSECriterion and the cross-entropy criterion implemented in ClassNLLCriterion. Finally, the StochasticGradient class provides a high level way to train the neural network of choice, even though it is easy with a simple for loop to train a neural network yourself.
Controlled Quantum Dynamics Group
Biologists do not take a quantum physics course during their studies because so far they were able to make sense of biological phenomena without using the counterintuitive laws of physics that govern the atomic scale. However, in recent years progress in experimental technology has revealed that quantum phenomena are relevant for fundamental biological processes such as photosynthesis, magneto-reception and olfaction. We have helped to initiate the development of this research field and are now working to discover how nature is harnessing quantum dynamics to optimize biological function. S.F.
The Internet’s Social Libraries: Pinterest and Pearltrees - Nvate
Miranda Moore Social media is something that most people use every day. Whether we’re updating our statuses on Facebook or taking pictures of our food on Instagram, social media is used to keep up with those near and far from us. A popular trend in social media is a sort of webpage described as a “social library.”
Pearltrees: Curation Tool Drops Flash And User Interface For Pintrest-like Format -SVW
Posted by Tom Foremski - May 23, 2014 Pearltrees (a former consulting client) this week introduced the 2.0 version of its popular web page curation tool built completely with HTML 5.0 and with a completely different user interface and metaphor. The tool now represents web pages as a series of rectangles in a "dynamic grid" allowing users to quickly organize and share their web collections. The prior interface was based on circles, or "pearls" connected in a molecular pattern to other "pearls." Sometimes new users thought it looked complicated and the user interface change simplifies people's first impressions. Patrice Lamothe, CEO and co-founder of Pearltrees (above) said the new interface in the latest version makes the tool more powerful and useful because of the drag and drop features, improved sharing, and content discovery technologies.
Pearltrees Develops its New Interface Further with 'Meaning'
Content and file curation and sharing platform Pearltrees has been updated today with new features that include ‘Meaning’, a new organization system. ‘Meaning’ is based on a traditional grid and allows users to drag and drop content into collections that can be shared with others and collaborated on with real-time synchronization. Pearltrees tells us that it hopes the new layout will encourage more collaboration between users.
except that what curators wish to share is the curation not just an rss equivalent in a boîte by mojojuju Nov 24
As the first version wouldn't be available from 1ft of December on, I am leaving Pearltrees for ever. It will lost for me all of its efficience and innovation and would become a waste of time for me. I keep my account just to take back slowly my contents... by le_chene Nov 9
That's pretty bad, because then you even cannot export your stuff to another app / tool. by deuxpont Jun 2
ver #1 used to tell me when someone ad the same pearl as me in their pearltree... this has not happened in #2 yet... is this function there.. or is #2 about collecting a load of boxes noone else wants to sort through with no structure to it??? by healingshores Jun 1
@amsika Also, why were pearltrees replaced with collections? Did you need a more accurate name? by elliottbelardo2 Jun 1
Some features are still missing, and will be implemented soon. As I said, this version 2.0 is a first version, and we'll improve it regularly, with 2.1, 2.2 etc... For the moment we couldn't implement the export feature in Pearltrees 2, that's why you have to go back to PT1 to do it. But be sure that it will be done soon. by amsika May 31
Another really weird thing in the ver#2 version of Pearltrees: The export feature (some people tend to save their data from too aggressive upgrade activities) in the new Pearltrees version is missing. I read the Pearltrees FAQ and learned that I can export my pearls to the HTML format (using them later as Firefox bookmarks for example - works actually; I tried it out) when I open the menu, then choose "settings" - but heck, there's no export feature at all. So I had to get back to "Check back Pearltrees 1" and open the ver#1 settings menu to get that feature. So, amsika, please don't tell me that ver#2 became easier to use! Again, I must say: P#1 thumbs up; P#2 thumbs down. by deuxpont May 31
@deuxponts Just in complement about your "and the really need to enligten the danger of public sharing "pearled" web content". I think HTML5 can help for to progress in that. If you are interested for example (I dont know) in : - what is really the cloud ? - what is really DRM ? Perhaps we can discuss about that after two or three weeks (or months), when enough people expressed their ideas about organization Pearltrees. Keep in touch. by reel May 31
Hello, Yes, the default format is now Pearltrees 2.0, so when you share your collections, they are seen in Pearltrees 2.0. It's very hard to maintain two different versions of Pearltrees. We manage to do it for the members who used to use Pearltrees 1, but we can't maintain it as a default version. Beside, the new format is even more easy to understand for everybody ;) Unfortunately, it's also very complex to manage and maintain two different apps on the App Stores, that's why we can only have one app. by amsika May 31
Well, the copyright problem is not a ver#2 novelty. In ver#1 it was less obvious due to the restriction of collectable items of a single treebranch. So, in any case there's some need of customer information IMO. Regarding the still available ver#1 view option, I have 2 problems: Pearltrees is designed to share content. So, if I want to share my ver#1 content, I also want my fellow pearlers to see a ver#1 tree structure, but they get collections without seeing my tree structure. 2nd problem: Guess I am using 40% of my work via smartphone. So I actually lost the special features of my mind-mapping work after getting the new app. The best thing that I can imagine would be to provide the fantastically working (guess HTML5 programmed) ver#1 app and the new ver#2 app. by deuxpont May 31
Thanks for your feedback deuxponts. Mixing both versions would have made it more complicated for everybody and it wouldn't have help us going toward our initial gaol: democratizing organization and sharing of digital contents. But please remember yet that if you're on a computer you can still access Pt1 from the left menu. Nothing is and will be lost. I'm not sure to understand your point about privacy. Nothing has changed in term of privacy with the new format. Collections has always been public by default. by amsika May 31
Hi healingshores, Creating ( and maintain) another entire site requires a lot of time and work. We' re just a small team of 15 people so we can't do this. But you can still use Pt 1 from the left menu of your account. by amsika May 31
Guess that's not easy. Ver #1 looks as if there's a lot of work and brainpower behind. But there is one thing that I don't understand: They could have left almost everything as it was (well, ver #2 actually has some improved capture/curatory features) and just add a new object class called "collection", having similar features like a "pearltree" plus the ability of containing more than a dozen items and using a grid structure instead of the bubble structure. If so, everybody was able to build ver#2-like collection "trees" or, alternatively ver#1-like trees containing collections as well, plus not leaving a lot of disappointed uses with ruined ver#1-pearltrees. There's a second problem with ver#2: The new concept is designed to share and extend non-professional collections quickly, and all collections are public by default. In Germany (where I live) exists a restrictive copyright law: Passionate pearltree-ver#2-users usually don't think about that and already have one foot in jail or will be forced to pay a lot of money for copyright-infringement by adhortatory chambers. So it is not unlikely that some affected persons might try to hold Pearltrees responsible for enticement of breaking laws. Actually I made my peace with ver#2: That’s why although Pearltrees lost it’s mindmap ability, I did not find a mindmap/curatory app with comparable social features (and pricing). There exist some great curatory apps like keeeb, but eg keeeb lacks in hierarchically organizing information; there exist great mindmap tools likewise, but their pricing structure is awkward: They restrain their social key features to the paid version, hence their social community remains pretty small. So thought it was easier to re-organize my pearltrees, replacing a lot of former text-formatted junctions by collections than recreating that stuff with a combination of a mindmap tool and keeeb. And heck - if I want to visualize my collection structure anyway, I still can use one of these nice’n fully fledged mindmap apps. In brief: After some days of crisis I got back to business. However, I am not happy with Pearltree’s game plan. It is self-destructive; they could have done better - and they really need to enlighten their members about the danger of public sharing “pearled” web contents. by deuxpont May 30
Hello deuxpont ! Let's talk about it by email. We're very interested in your feedback! participation@pearltrees.com Thanks! by amsika May 23
I am not convinced by this pearl-unlike design. Moreover, I'm badly missing the visual structure of pearltrees#1. by deuxpont May 23
