Top 10 Data Mining Algorithms, Demystified
Once you know what they are, how they work, what they do and where you can find them, my hope is you’ll have this blog post as a springboard to learn even more about data mining.
What are we waiting for? Let’s get started!
Here are the algorithms:
1. C4.5
2. k-means
3. Support vector machines
4. Apriori
5. EM
6. PageRank
7. AdaBoost
8. kNN
9. Naive Bayes
10. CART
Interesting Resources
Now it’s your turn…
1. C4.5
What does it do?
C4.5 constructs a classifier in the form of a decision tree. In order to do this, C4.5 is given a set of data representing things that are already classified.
Wait, what’s a classifier?
A classifier is a tool in data mining that takes a bunch of data representing things we want to classify and attempts to predict which class the new data belongs to.
What’s an example of this?
Sure, suppose a dataset contains a bunch of patients. We know various things about each patient like age, pulse, blood pressure, VO2max, family history, etc. These are called attributes.
Now:
Given these attributes, we want to predict whether the patient will get cancer. The patient can ...

Come analizzare la Voce umana con uno Spettrogramma
Aggiornamento post 10.06.11 Nuova versione v.4
Uno dei campi di applicazione più importanti degli spettrogrammi è l'analisi della voce umana, in particolare l'utilizzo piú frequente é quello relativo al riconoscimento e alla comparazione di voci umane per svariate finalità.
La bocca, le cavità nasali e il complesso della struttura timbrica vocale, determina un mix unico di frequenze che compongono ciascuna singola voce umana, esattamente come fosse una impronta vocale digitale.
Sonogram è un sofisticato programma disponibile anche in versione di prova gratuita, originariamente sviluppato presso il Centro di Ricerca per l'Intelligenza Artificiale Tedesco ( Deutsches Forschungszentrum für künstliche Intelligenz DFKI ) e attualmente reso open source dallo sviluppatore Christoph Lauer.
Sviluppato interamente in Java, Sonogram é disponibile per Windows, Linux, SUN / Solaris e Macintosh OSX, e dispone di una serie di interfacce grafiche anche 3D per effettuare sofisticate analisi e visualizzazioni di segnali vocali e sonori utilizzando i seguenti sei protocolli :
1. Fast Fourier Transformation (FFT)
2 - Linear Predictive Coding (LPC)
3 - Wavelet Transformation
4 - Cepstral Analysis
5 - Autokorrelation
6 - Pitch Detection
Guarda un filmato con una panoramica di schermate e menu del programma in funzione :
L'utilizzo di Sonogram presuppone un minimo di conoscenza di programmi di visualizzazione audio come Audacity, é comunque presente all'interno del programma una completa sezione Help con tanto di file audio campione per effettuare i primi test di analisi vocale.

Microsoft Partners With 18 More Vendors To Pre-Install Apps On Android Tablets
Today Microsoft announced partnerships with 18 device manufacturers to pre-install apps such as Office, OneDrive, and Skype on future Android tablets. Microsoft already has existing deals in place with companies like Dell, Samsung, and Pegatron, and we've seen the results of those agreements on devices like the Venue 8 7840 and the Galaxy S6. Today's announcement focuses more on tablets, which is a natural area of focus for Microsoft as their suite of Office applications are made for Android tablets.
Microsoft's list of partnered companies mostly consists of regional manufacturers that serve a specific country. However, both LG and Sony appear on the list, which means that Microsoft's apps will be shipping on future devices to countries all over the world. The press release specifically states that Sony's Xperia Z4 tablet will begin shipping with the apps within 90 days, and states that a future tablet from LG will include them as well.
Microsoft's partnerships represent a new direction for a company that once used their suite of Office apps as a way to lead users to Windows devices. You can view the entire list of new partner companies in the source below.

Need Timing Diagrams? Try Wavedrom
When working with anything digital, you’re going to end up reading or writing a timing diagram before long. For us, that’s meant keeping (text) notes, drawing something on a napkin, or using a tool like Inkscape. None of these are ideal.
An afternoon’s search for a better tool ended up with Wavedrom.
Just so you know where we’re coming from, here’s our list of desiderata for a timing diagram drawing solution:
- Diagrams have a text-based representation, so their generation can be easily scripted and the results versioned and tracked throughout project development
- Command-line rendering of images, because we like to

Finally, VR For Four Eyes
In the next few years, VR headsets will be everywhere, and everyone will slowly recede into their own little reality that is presented on high-resolution displays right in front of their eyes. One specific group will be left out: eyeglass wearers. VR just doesn’t work with eyeglasses, and a few people in Germany are fixing this problem. They’re creating custom prescription lenses for Google Cardboard, giving anyone with glasses the opportunity to look just a little more hipster.
The folks behind this Indiegogo already run a specialty optics shop in Germany. They have the tools to make custom lenses for …read more

Tessel 2, A $35 Linux Computer That’s Truly Open Source
We’ve seen the first version of the Tessel a few years ago, and it’s still an interesting board: an ARM Cortex-M3 running at 180MHz, WiFi, 32 Megs of both Flash and RAM, and something that can be programmed entirely in JavaScript or Node.js. Since then, the company behind Tessel, Technical Machines, has started work on the Tessel 2, a board that’s continuing in the long tradition of taking chips from WiFi routers and making a dev board out of them. The Tessel 2 features a MediaTek MT7620 running Linux built on OpenWRT, Ethernet, 802.11bgn WiFi, an Atmel SAMD21 serving as …read more

Algorithm removes reflections from photos
Posted By: RobertoOrtiz

Text:
"At the Computer Vision and Pattern Recognition conference in June, MIT researchers will present a new algorithm that, in a broad range of cases, can automatically remove reflections from digital photos. The algorithm exploits the fact that photos taken through windows often feature two nearly identical reflections, slightly offset from each other."

Using Big Data Analytics to Improve IT Operations
To deliver high-performance and stable IT operations, staffs end up taking shortcuts, bypassing automated and manual processes. Eventually, it leads to applicaton defects and infrastructure failures. Nevertheless, IT departments need to be able to control their environments, diagnose and pre-empt problems and incidents. Unfortunately, most of existing IT tools don't collect adequate data and don't do a robust job of handling the data they collect. Activity dashboards are cluttered, and have too many alerts that users end up ignoring them.
Making Big Data Analytics Actionable for IT
An organization's IT environment typically generates Terabytes of data about system metrics, change logs, event logs and other operational data. It is possible to obtain extremely granular data about the history and current state of your IT environment. The key is to make this data actionable. However, the challenge ...

“Bricking” Microcontrollers in LEGO Motivates Young Programmers
Back when he was about seven years old, [Ytai] learned to program on an Atari 800XL. Now he has a seven-year-old of his own and wants to spark his interest in programming, so he created these programmable LEGO bricks with tiny embedded microcontrollers. This is probably one of the few times that “bricking” a microcontroller is a good thing!
The core of the project is the Espruino Pico microcontroller which has the interesting feature of running a Java stack in a very tiny package. The Blocky IDE is very simple as well, and doesn’t bog users down in syntax (which …read more

Architects Design Wooden Bicycle Frame to Explore Structural Engineering
Bike manufacturer AERO created this prototype bicycle frame from layers of birch to test wooden structural techniques that can be applied to architectural projects. The bicycle was conceived by Martino Hutz, Atanas Zhelev and Mariya Korolova whilst working on a wooden structural design for a London house, during their studies at the University of Applied Arts Vienna. The bike frame is composed of lamellas—millimeter-thick sheets of birch wood glued together into strips that splay out at the points where the crank and peddle are fixed, as well as below the seat. A beautiful bike...(Read...)
