Evolution Of Learning Is Key To Better Artificial Intelligence

#artificialintelligence

Since "2001: A Space Odyssey," people have wondered: could machines like HAL 9000 eventually exist that can process information with human-like intelligence? Researchers at Michigan State University say that true, human-level intelligence remains a long way off, but their new paper published in The American Naturalist explores how computers could begin to evolve learning in the same way as natural organisms did โ€“ with implications for many fields, including artificial intelligence. "We know that all organisms are capable of some form of learning, we just weren't sure how those abilities first evolved. Now we can watch these major evolutionary events unfold before us in a virtual world," said Anselmo Pontes, MSU computer science researcher and lead author. "Understanding how learning behavior evolved helps us figure out how it works and provides insights to other fields such as neuroscience, education, psychology, animal behavior, and even AI. It also supplies clues to how our brains work and could even lead to robots that learn from experiences as effectively as humans do."


Its (Almost) the End of the World As We Know It

#artificialintelligence

To be fully transparent, I started writing this post in late 2018 in an attempt to detail my own "Things you should be focused on as an investor/consumer in 2019," but the year got ahead of me as interesting projects materialized and so too did my resolution to write more! Some of these projects have already progressed further than I had imagined - I have been fortunate enough to have spent the last two years working, researching & exploring areas that I find most pivotal to improving our quality of life, and we seem to be at an interesting inflection point among all. There are countless applications of Artificial Intelligence either already deployed or in development, with many more envisioned every day. I am most excited for AI that will automate and assist the best interests of the individual: personalized recommendations. I believe said recommendations, those pesky things that currently inundate our platforms with little explanation, should be more transparent and easier to understand.


Machine learning python

#artificialintelligence

With modern technology, such questions are no longer bound to creative conjecture. You have just found Keras. Today i will give a brief introduction over this topic which created headache for me when i was learning this. All video and text tutorials are free. I use Anaconda package that almost wraps up all the Python packages including Jupyter notebook.


This new airplane model will know when you've unbuckled your seatbelt

#artificialintelligence

Travelers know there is very little privacy when it comes to air travel. Before passengers are even allowed to board an aircraft, they have to shed their jackets, take off their shoes, and walk through an X-ray contraption that scans their entire bodies. As flyers settle into their (usually rigid and uncomfortable) seats, the active surveillance seems to end there. But in a few years, Airbus's latest "connected cabin" aircraft experience might change that. The innovation, which was revealed in September, will let flight attendants survey the cabin more closely by employing sensors in the lavatory and cabin, Time reported.


Startup Bay Labs Uses AI for Heart Disease Diagnosis NVIDIA Blog

#artificialintelligence

And humans need health screenings, especially for the heart. That's because heart disease is the leading cause of death worldwide. With deep learning, heart disease diagnosis is becoming easier and more accessible -- which in turn can improve treatment and patient outcomes. Echocardiograms -- ultrasound tests that generate images of the heart -- are used to detect and manage heart disease cases. An echo, as it's commonly called, is also used as an assessment tool for specific populations, such as chemotherapy patients, because of their increased risk of heart failure.

This course is not part of my deep learning series, so there are no mathematical prerequisites - just straight up coding in Python. You'll start by preparing your environment for NLP and then quickly learn about language structure and how we can break sentences down to extract information and uncover the underlying meaning.


Why buying and selling a house could soon be as simple as trading stocks

#artificialintelligence

On a recent weeknight, Dahlia and Adam Brown came home to their spacious Colonial on a quiet cul-de-sac in Marietta, Ga. The Browns both work demanding jobs and have two young sons. They bought the house in June using Knock, a company that's trying to revolutionize the real-estate industry with a "home trade-in platform" making it easier to buy and sell at once. That solution was ideal for the Browns, who are just as busy as most couples but more introverted, making the idea of prospective buyers tramping through their private space seem excruciating. Across town, Martha Seay was overseeing movers in a rambling brown ranch-style house nestled among tall hickory trees. The day before, she had closed on the sale of the house, where she and her husband had raised their family, to the real-estate company Zillow.


Avoidable blindness: making global sight loss a thing of the past

#artificialintelligence

Sight, the precious sense that brings us perspective and wonder, is under unprecedented attack. Despite huge clinical and technological advances, record numbers of people are suffering from avoidable blindness. The economic burden of sight loss has been estimated at ยฃ28.1 billion a year in the UK, yet more than 50 per cent of blindness is avoidable. These stark statistics are made even more disturbing by the fact that, while health and longevity profiles across all disabilities are improving, sight loss is becoming worse. Research projects are bringing us bionic eyes, stem cell regrowth and artificial intelligence (AI) that can combat the ravages of eye disease. But they are ranged against formidable harbingers of darkness in obesity, outmoded systems, poor funding and ageing populations.


Verified Uncertainty Calibration

arXiv.org Machine Learning

Applications such as weather forecasting and personalized medicine demand models that output calibrated probability estimates - those representative of the true likelihood of a prediction. Most models are not calibrated out of the box but are recalibrated by post-processing model outputs. We find in this work that popular recalibration methods like Platt scaling and temperature scaling, are (i) less calibrated than reported and (ii) current techniques cannot estimate how miscalibrated they are. An alternative method, histogram binning, has measurable calibration error but is sample inefficient - it requires $O(B/\epsilon^2)$ samples, compared to $O(1/\epsilon^2)$ for scaling methods, where $B$ is the number of distinct probabilities the model can output. To get the best of both worlds, we introduce the scaling-binning calibrator, which first fits a parametric function that acts like a baseline for variance reduction and then bins the function values to actually ensure calibration. This requires only $O(1/\epsilon^2 + B)$ samples. We then show that methods used to estimate calibration error are suboptimal - we prove that an alternative estimator introduced in the meteorological community requires fewer samples - samples proportional to $\sqrt{B}$ instead of $B$. We validate our approach with multiclass calibration experiments on CIFAR-10 and ImageNet, where we obtain a 35% lower calibration error than histogram binning and, unlike scaling methods, guarantees on true calibration.


Machine Learning Optimization Algorithms & Portfolio Allocation

arXiv.org Machine Learning

Portfolio optimization emerged with the seminal paper of Markowitz (1952). The original mean-variance framework is appealing because it is very efficient from a computational point of view. However, it also has one well-established failing since it can lead to portfolios that are not optimal from a financial point of view. Nevertheless, very few models have succeeded in providing a real alternative solution to the Markowitz model. The main reason lies in the fact that most academic portfolio optimization models are intractable in real life although they present solid theoretical properties. By intractable we mean that they can be implemented for an investment universe with a small number of assets using a lot of computational resources and skills, but they are unable to manage a universe with dozens or hundreds of assets. However, the emergence and the rapid development of robo-advisors means that we need to rethink portfolio optimization and go beyond the traditional mean-variance optimization approach. Another industry has faced similar issues concerning large-scale optimization problems. Machine learning has long been associated with linear and logistic regression models. Again, the reason was the inability of optimization algorithms to solve high-dimensional industrial problems. Nevertheless, the end of the 1990s marked an important turning point with the development and the rediscovery of several methods that have since produced impressive results. The goal of this paper is to show how portfolio allocation can benefit from the development of these large-scale optimization algorithms. Not all of these algorithms are useful in our case, but four of them are essential when solving complex portfolio optimization problems. These four algorithms are the coordinate descent, the alternating direction method of multipliers, the proximal gradient method and the Dykstra's algorithm.
