News Commentary: Will crosswords cross up computers?
Dr. Fill is the creation of Matt Ginsberg, an artificial intelligence scientist and cruciverbalist, what you should fill in if you're ever starting at the clue: "a creator of crossword puzzles. " He set off on the project a little more than a year ago, in part because he felt Watson left the public with a false impression about the nature of artificial intelligence. That, plus improving artificial intelligence, lets us harness computers to solve increasingly complex problems. (more)
News Sebastian Thrun Will Teach You How to Build Your Own Self-Driving Car, For Free
Tweet Last August, Sebastian Thrun, the brains behind Google s self-driving cars and one of the world s top AI experts, offered an online version of Stanford s Introduction to Artificial Intelligence course to absolutely anyone who wanted to take it, for free. It turned out to be just a little bit popular (over 150,000 students enrolled), and now Thrun is offering a new, totally free, seven-week online course called Programming a Robotic Car. You ll need to know a little bit of Python (the programming language, not the reptile), but it s an easy language to learn if you have any sort of programming background, and there are plenty of helpful course materials to check out. I don t know about you, but I m the suspicious type, and when something comes along that sounds too good to be true (like a totally free robotics course taught by some of the smartest guys in the world that s open for anyone to enroll in), I start wondering how they plan to pull that off.

News Is This Code Part of Majel, Android's Future Personal Assistant?
Someone tried to mess around with the FaceUnlock application code from the Android SDK, and stumbled upon this code, which seems to include answers, as if given by a personal assistant or such. Weve heard some rumors a few months back that Google may be working on a personal assistant as part of their Google X projects, and theyve been doing this for years. These rumors came from someone who claimed he was involved with Google X, and he wanted to give a hint about what theyve been working on: This is in total violation of the NDA, but I dont care anymore. The central focus of Google X for the past few years has been a highly advanced artificial intelligence robot that leverages the underlying technology of many popular Google programs. (more)
News Controlling neuroprosthetics with your mind
Neuroscientists have found that the brain is more flexible and trainable than previously thought, opening the door to development of thought-controlled prosthetic devices to help people with spinal cord injuries, amputations and other impairments. The study advances work by researchers who have been studying the brain circuits used in natural movement, to mimic them for the development of prosthetic devices. The insights suggest that learning to control a BMI (brain-machine interface), which is inherently unnatural, may feel completely normal to a person, because this learning is using the brains existing built-in circuits for natural motor control. The rats were fitted with a brain-machine interface that converted EEG brain waves into auditory tones. (more)
News The problem with investing based on pattern recognition
A famous story in artificial intelligence is how the US military developed algorithms to determine whether an image had a tank in it. They used a standard machine learning method: feed the computer a training set of photos, some of which had tanks in them and some of which didnt, and let algorithms identify which features in the photos correlated to tanks being shown. Since the features the computer identified were embedded in complicated mathematical equations, no one could figure out what it was really doing and therefore why it stopped working.Eventually someone realized that in the training set, all of the images with tanks were taken on a cloudy day, and all the images without tanks were taken on a sunny day. In the context of markets, it can cause companies and sectors with the right patterns to be overvalued, and ones with the wrong patterns to be undervalued. (more)
News Skytree Uses Machine Learning To Crunch Big Data

News Have We Met? Tracing Face Blindness to Its Roots
Those with prosopagnosia, also known as face blindness, can see perfectly well, but their brains are unable to piece together the information needed to understand that a collection of features represents an individuals face. One of the keys to understanding face recognition, it seems, is understanding how the brain comes to recognize voices. But by testing for these two conditions simultaneously, researchers at the Max Planck Institute for Human Cognitive and Brain Sciences in Germany recently found evidence that face and voice recognition may be linked in a novel person-recognition system. The researchers found that regions of the brain already associated with facial recognition, like the fusiform face area in the occipital lobe, are directly linked to regions responsible for voice recognition, mostly in the temporal lobe.

News Tinkering with evolution: Ecological implications of modular software networks
Now, researchers in the Department of Ecology and Evolutionary Biology at Princeton University have shown the inverse namely, that network theory, when applied to software systems, provides surprising insights into biology, ecology and evolution. Specifically, they explored evolutionary behavior in complex systems by analyzing how the Debian GNU/Linux operating system utilizes modular code. While Fortuna notes that quantifying the increase of the codes modular structure time was the main insight of their study, he points out that reuse of code and softwares hierarchical structure were suggested by the pioneering work of Ricard V. The idea of using the network of dependencies and conflicts of different releases of the Debian operating system as a case study has facilitated the understanding of how code development evolves over time without the need to go deeper into the details of the code itself.

News Scientists Model Brain to Teach Computers to Recognize
Researchers at the beginning of the computer revolution assumed that teaching a computer to recognize something would be easy. Researchers from Los Alamos National Laboratory, Chatham University, and Emory University created a neural network with a slightly different structure than what is usually used in research. Most neural network research involves wiring artificial neurons from one layer to others in another layer. In this case, the researchers decided to wire some neurons to other neurons in the same layer, creating lateral connections. (more)
News Neural network learns to identify group sizes without knowledge of numbers
After feeding the network 51,800 images, where each was a unique layout of rectangles of various sizes, the researchers found that the new images generated by the system began to demonstrate an awareness of the relative size of different groups without having to perform any counting. Next, to demonstrate, ANS, the team fed the system another program that allowed the system to compare different groups that it had seen during the first run and found, based on new images generated, that the system was able to make educated guesses about which was bigger or smaller; Teaching computer systems to learn to use ANS is but one step towards creating machines that think rather than simply crunch numbers for us, and the hope is that one day, such systems can be put into robots to make them as useful as those weve seen in movies for decades.

News Artificial intelligence: Getting better at the age guessing game
The active learning algorithm is faster and more accurate in guessing the age of an individual than conventional algorithms. They have, for example, developed computer algorithms for facial age classification -- the automated assignment of individuals to predefined age groups based on their facial features as seen on video captures or still images. A person can teach a computer to make better guesses by running its algorithm through a large database of facial images of which the age is known using sets of labeled images, but acquiring such a database can be both time-consuming and expensive. The technology could find use, for example, in digital signage where the machine determines the age group of the viewer and displays targeted advertisements designed for those age groups, or in interactive games where the machine automatically presents different games based on the players' age range.

News How does our brain see Jesus face on a tortilla?
Whether its New Hampshires erstwhile granite Old Man of the Mountain, or a face on Mars, our brains are adept at locating images that look like faces. nonface Sinha and his students set out to investigate how that brain region decides what is and is not a face, particularly in cases where an object greatly resembles a face. To help them do that, the researchers created a continuum of images ranging from those that look nothing like faces to genuine faces. They found images that very closely resemble faces by examining photographs that machine vision systems had falsely tagged as faces. (more)

News Robot reveals the inner workings of brain cells: Automated way to record electrical activity inside neurons in the living brain
Gaining access to the inner workings of a neuron in the living brain offers a wealth of useful information: its patterns of electrical activity, its shape, even a profile of which genes are turned on at a given moment. Using this technique, scientists could classify the thousands of different types of cells in the brain, map how they connect to each other, and figure out how diseased cells differ from normal cells. In all these cases, a molecular description of a cell that is integrated with [its] electrical and circuit properties has remained elusive, says Boyden, who is a member of MIT's Media Lab and McGovern Institute for Brain Research. Kodandaramaiah, Boyden and Forest set out to automate a 30-year-old technique known as whole-cell patch clamping, which involves bringing a tiny hollow glass pipette in contact with the cell membrane of a neuron, then opening up a small pore in the membrane to record the electrical activity within the cell.

News Is Machine Learning v Domain Expertise the wrong question?
About James Taylor: CEO Decision Management Solutions James Taylor is CEO and Principal Consultant at Decision Management Solutions and one of the leading experts in decision management and decisioning technologies. Some decisions are heavily influenced by policy and regulation (deciding if a claim is complete and valid for instance) while others are more heavily influenced by the kind of machine learning insight common in analytics (deciding if the claim is fraudulent might be largely driven by a Neural Network that determines how normal the claim seems to be). We could also ask if there are really any decisions where machine learning or analytics cannot help at all (probably but only because the decision-makers dont have access to data that would help or because they are obliged to follow a precise set of regulations/policies). Or we could ask if there were any decisions that only required know-how that can be derived automatically using machine-learning (probably not, most business decisions involved some policy and regulations that are fixed even if we can replace experience with machine learning).

News Long Term Memory Encoding in the Brain
Researchers may finally have uncovered the brain mechanism for storage of long term memories. The researchers summarize their discoveries this way:"We demonstrate a feasible and robust mechanism for encoding synaptic information into structural and energetic changes of microtubule (MT) lattices by calcium-activated CaMKII phosphorylation. We suggest such encoded information engages in ongoing MT information processes supporting cognition and behavior, possibly by generating scale-free interference patterns via reaction-diffusion or other mechanisms. As MTs and CaMKII are widely distributed in eukaryotic cells, the hexagonal bytes and trytes suggested here may reflect a real-time biomolecular information code akin to the genetic code. (more)

Functional specificity refers to the idea that discrete parts of the brain handle distinct tasks. To determine this, the researchers analyzed each subject individually using fMRI, making sure thatpatterns of activity in one brain would only ever be compared to patterns of activity from that same brain.The researchers spent the first 10 to 15 minutes of each fMRI scan having their subject do a fairly sophisticated language task while tracking brain activity. This way, they established where the language areas lie in that individual subject, so that later, when the subject performed other cognitive tasks, they could compare those activation patterns to the ones elicited by language. The researchers said the results don t imply that every cognitive function has its own dedicated piece of cortex. (more)

Today, Torralba is a tenured associate professor of electrical engineering and computer science at MIT, and an affiliate of the Computer Science and Artificial Intelligence Laboratory (CSAIL), where he develops AI systems that can interpret images to understand what scenes and objects they contain. I wanted to build systems that could put objects into context, to try to understand how different objects relate to each other, he says. So he began developing systems that used information gathered from the entire image to help identify individual objects. If an image contains an object perched on top of a table, for example, that object is unlikely to be anything very large, narrowing down considerably the number of things it could possibly be. (more)
News Artificial intelligence for quantum chemistry
Drawing on a database of quantum chemical results for over 7000 molecules, their program could give the atomisation energies of unfamiliar molecules to within 1% - and in a billionth of the time required for a full approximation. Von Lilienfeld's team trained the algorithm on a subset of molecules in the database, comparing their matrices to find 'distances' between molecules - a measure of the difference between the molecules in terms of their matrices. In the case of finding an unknown molecule's atomisation energy, the distances between the unknown molecule and all the known molecules gave weights for how much each known atomisation energy could contribute to an estimate for the unknown molecule. The researchers found that with a landscape of more than 5000 molecules, the error for predicting atomisation energies of new molecules drops below 10kcal/mol, approaching the 5kcal/mol accuracy of hybrid DFT.

News Secret Formula For Writing A Hit Song
Mathematicians DiscoverThough math is usually used to tell you if a song was a hit based on sales, scientists from the University of Bristol believe they have " The Hit Equation. " A group focused on artificial intelligence developed machine learning algorithms that mined the characteristics of top hits to develop a formula for key musical features that determine whether a song will be a hit. I don't know how Hit Song Science does its magic, but they claim to analyze " fundamental characteristics of all music " including brightness, tempo and changes over time, to identify hit potential in relationship to changing trends.

As a baseball fan, my instinct would be to divide the major leagues into teams that emphasize pitching and those that focus on hitting. (more)
News Facial recognition software spots family resemblance
FACIAL recognition software that's as good as people at spotting family resemblances could help to reunite lost family members - or help the likes of Facebook work out which of your friends are blood relatives. To do this, the team used a database of public figures and their parents or children - such as French president Nicolas Sarkozy and his son Jean - and fed the program 320 pairs each of parent-child matches and mismatches. The software then compared the difference between a test pair of photos with pairs of photos in its database. In tests using 160 pairs - 80 parent-child matches and 80 mismatches - the system had a success rate of 68 per cent. (more)

News Why Allow Customers to Suffer the Consequences from Bad Chat Translations?
SMT, Lionbridge officials explain, has contributed to the growth in machine translation applications in recent years since it can analyze vast amounts of previously translated material, and target-language texts to create what Lionbridge officials say is a real-time translation in a fraction of the time that it takes to produce traditional rules- based translation systems. The way it works, is customer use the Customizer along with customer-supplied translation memories and glossary assets, GeoFluent then translates for each customer by application domain, applying machine-learning methods to analyze your translation memories, glossaries and target- language documents, Lionbridge officials explain, consistent with your terminology and branding.

News Artificial intelligence joins the fossil hunt
Success in finding bones boils down to a lot of luck, says Robert Anemone of Western Michigan University in Kalamazoo, who once blundered into "the best locality we ever found" - a cache of early primate bones from between 40 and 50 million years ago - after making a wrong turn during a trip in the Great Divide basin of south-western Wyoming. So the team began by feeding the software a list of known locations in the 10,000-square-kilometre Great Divide basin, labelling them either as being fossil-rich or belonging to one of four other categories - barren, forest, scrub or wetland. Using only the satellite data, the computer had learned that the area's fossil sites were in sandstone - but not all sandstone has fossils at the surface. It correctly identified 79 per cent of the known fossil sites as likely to contain fossils, and correctly classified 84 per cent of all the other locations, Emerson says. (more)
News Computers found more accurate than doctors in breast-cancer diagnosis
Computer analyses of breast cancer microscopic images were found more accurate than those conducted by humans, computer scientists at the Stanford School of Engineering and pathologists at the Stanford School of Medicine report. Medical science has long used three specific features for evaluating breast cancer cells: what percentage of the tumor is comprised of tube-like cells, the diversity of the nuclei in the outermost (epithelial) cells of the tumor and the frequency with which those cells divide (a process known as mitosis). These three factors are judged by sight with a microscope and scored qualitatively to stratify breast cancer patients into three groups that predict survival rates. In fact, they discovered that the characteristics of the cancer cells and the surrounding cells, known as the stroma, were both important in predicting patient survival. (more)

Video AGIRI 2006 Workshop Keynote Speaker: Dr. Stan Franklin (Dir. Institute for Intelligent Systems, University of Memphis) - A Cognitive Theory of Everything: The LIDA Technology as an Artificial General Intelligence.
"Implementing and fleshing out a number of psychological and neuroscience theories of cognition, the LIDA conceptual model aims at being a cognitive 'theory of everything.' With modules or processes for perception, working memory, episodic memories, 'consciousness,' procedural memory, action selection, perceptual learning, episodic learning, deliberation, volition, and non-routine problem solving, the LIDA model is ideally suited to provide a working ontology that would allow for the discussion, design, and comparison of AGI systems. The LIDA technology is based on the LIDA cognitive cycle, a sort of 'cognitive atom.' The more elementary cognitive modules play a role in each cognitive cycle. Higher-level processes are performed over multiple cycles. This talk will give a quick overview of the LIDA conceptual model, and its underlying computational technology." May 20, 2006. (more)

"Nowadays terrorism is one of the biggest troubles that almost every country faces. It mainly influences the economy and the well being of the citizens and this effect is relatively larger in the developed countries. Since the financial sources of terrorist groups can be regarded as black money, the solutions against the money laundering actions can be expected to identify the transactions of the terrorists. Then, blocking their accounts could slow down their actions if cannot stop. In many countries, the financial institutions are expected to inform compliance regulation bodies about any persons or transactions that they think suspicious. To cope with this necessity, various software packages for anti money laundering (AML) have been developed and are commercially available."
