Using Natural Language Processing for Spam Detection in Emails

#artificialintelligence

Through the above, we have successfully fit a bi-directional LSTM model on our email data, and detected 125 of 1114 emails as spam. Since the percentage of spam in data is often low, Measuring the model's performance by accuracy alone is not recommended. We need to evaluate it using other performance metrics as well, which we'll look at below. Precision and recall are the two most widely used performance metrics for a classification problem to get a better understanding of the problem. Precision is the fraction of the relevant instances from all the retrieved instances.


Deep learning can beat other forecast methods โ€“ Bank of Korea research - Central Banking

#artificialintelligence

Deep learning โ€“ an advanced form of artificial intelligence โ€“ can be more accurate in predicting outcomes, compared with conventional econometric approaches, according to research from Bank of Korea (BoK). The research paper tested predictions of monthly exports from Korea and daily Korean won-US dollar exchange rates. It found that deep learning approaches produced better results even with the sorts of non-granular data sets that are normally used for conventional econometric models.


Creating A Chess AI using Deep Learning

#artificialintelligence

When Gary Kasparov was dethroned by IBM's Deep Blue chess algorithm, the algorithm did not use Machine Learning, or at least in the way that we define Machine Learning today. This article aims to use Neural Networks to create a successful chess AI, by using Neural Networks, a newer form of machine learning algorithms. Using a chess dataset with over 20,000 instances (contact at victorwtsim@gmail.com for dataset), the Neural Network should output a move, when given a chess-board. These libraries are the prerequisites to create the program: os and pandas are to access the dataset, python-chess is an "instant" chess-board to test the neural network. Numpy is necessary to perform matrix manipulation.


Where is AI Going in 2021?

#artificialintelligence

Where is AI going to in 2021? I was asked this question by my friends including Tripp Braden, Danielle Guzman and April Rudin, as well as others. For a definition of AI, Machine Learning and Deep Learning see the article that I authored entitled "An Introduction to AI". Edge Computing refers to on the device closer to where the data is generated at the edge of the network. We'll see AI increasingly inferencing on the devices around us including mobile devices, sensors and smart cameras with Graphical Processing Units (GPUs, or specialised AI chips for sake of simplicity) embedded in the device.

Retired Chess Grandmaster, AlphaZero AI Reinvent Chess

#artificialintelligence

Russian chess grandmaster Vladimir Kramnik is working with DeepMind's chess program, AlphaZero, to analyze new variants in an attempt to reinvent the popular strategy board game. Vladimir Kramnik, Classical World Chess Champion from 2000 to 2006, has proposed nine new chess variants last Wednesday, September 9. He has worked together with the artificial intelligence (AI) laboratory DeepMind, a subsidiary of Google's parent company Alphabet Inc, to evaluate his proposals with the help of the AlphaZero AI. In a report submitted to Cornell University, Nenad Tomaลกev, Ulrich Paquet, and Demis Hassabis from DeepMind worked with grandmaster Vladimir Kramnik to assess game balance in the new variations with help from AlphaZero. It defines AlphaZero as "a reinforcement learning system that can learn near-optimal strategies for any rules set from scratch without any human supervision, and provides an in silico alternative for game balance assessment."


From von Neumann to Memory-Augmented Neural Networks

#artificialintelligence

The traditional von Neumann architecture differentiates between a CPU (Central Processing Unit) and three levels of memory: registers -- very fast, but with storage capability limited to a few values; main memory (e.g. RAM)-- faster, with enough storage to accommodate for instructions and data to run a program, and external memory (e.g. Memory-Augmented Neural Networks (MANNs) are differentiable versions of the von Neumann architecture (more on this in the next section). The bulk of the neural network can be thought of as the CPU. Certain architectures like RNNs (Recurrent Neural Networks) have built-in memory that is analogous to the registers, storing short-term information.


Welcoming new guidelines for AI clinical research

#artificialintelligence

There are currently hundreds of published retrospective reports that fall under the rubric of'clinical trials' of AI, but they are not really trials at all. While essential for laying the groundwork, these are in silico assessments of datasets to determine how well a deep neural network performs a clinical task, compared with a small number of physicians. Such AI reports do not simulate clinical practice but instead work from a cleaned, relatively pristine, annotated dataset. The real world of medicine, in contrast, is messy, with plenty of missing data, lots of it unstructured, and its focus is caring for patients rather than developing an analytical substrate. The stark contrast of a clinical environment versus an in silico one cannot be overemphasized, and hence clinical trials of AI are needed.


Post-Pandemic, Human Interactions Still Power Global Business

#artificialintelligence

Why haven't the powerful AI interventions of our time, like Google's DeepMind, been at the forefront of developing solutions to the current COVID-19 crisis? The highly sophisticated machine learning programs that establish complex neural networks to make connections and reach meanings without relying on pre-defined behavioral algorithms rely on past data patterns. The bigger and richer the base data, the more robust the solution -- and herein lies the challenge: Events like the current pandemic have no precedent in scale and scope and therefore no historical data to draw upon. Unprecedented risks without past data patterns pose the most significant threat globally, as stated in the World Economic Forum's Global Risk Report 2020. Our collective ability to build resilience and rebound from a crisis -- now and in the future -- depends on the distinctly human capability for proactive planning and navigating new, previously unknown risks that pose a serious global threat.
