Review latest investments to AWS' machine learning platform

#artificialintelligence

AWS is always adding services and features, but it's been particularly active with its AI services of late. For example, AWS rolled out 13 machine learning products at re:Invent 2018 alone. AWS' massive investment in product development is good for users, but this pace of change makes it difficult for IT professionals to keep up. The Deep Learning AMIs and Containers target developers who build sophisticated custom models with the AWS machine learning platform and DevOps teams charged with deploying them on cloud infrastructure. In contrast, the managed services, which join similar products for image recognition, speech transcription and interactive chatbots, are designed for data scientists and non-specialists who want to analyze large and complicated data sets using techniques that are more advanced than standard statistical analysis.


Key Time Steps Selection for CFD Data based on Deep Metric Learning

#artificialintelligence

As one of the main technologies of flow visualization, key time steps selection plays a key role in solving storage limit and has been intensively studied. In this paper, we introduce Deep Metric Learning (DML) into key time steps selection for Computational Fluid Dynamics (CFD) data and propose a local selection method based on DML. In specific, the proposed method samples small patches from CFD data, trains a Siamese deep neural network which has a symmetry structure with two Convolutional Neural Networks (CNN), and then selects the key time steps according to the similarities between consecutive time steps which are assessed by the networks. Compared with one of the existing local selection methods, the Myers's method, our method has advantages in accuracy, precision and recall, and the selection results are better. Experimental results also demonstrate the good generalization of the proposed method on CFD datasets.

This work used the XStream computational resource, which is supported by the National Science Foundation Major Research Instrumentation program (ACI-1429830). This work used the shared FACS facility, which is supported by NIH S10 Shared Instrument Grant (S10RR027431-01). We thank the NIH Tetramer Facility for providing recombinant HLA-DR monomers for the peptide binding experiment. We thank M. Nielsen for providing insights regarding implementation of the NetMHCIIpan algorithm.


Comparing Neural Network Architectures

#artificialintelligence

After reading François Chollet's wonderful book Deep Learning with Python I became curious about the different neural network architectures and which one is the best for various tasks. I had already thought of getting some practice with word data so I decided to take on the project of classifying the language that a word is written in. The first direction that I think of when working with words is to use recurrent neural networks. Chollet's book also suggests that a series of 1D convolutions could be appropriate. Finally, I found a nice blog post that achieved a similar task using a simple fully connected network. This was the best opportunity to try each of these nice networks on the same project!


Useful Comparison Tables for AI, Data Science, IoT & Cloud

#artificialintelligence

Comparison tables can be handy when it comes to getting a quick overview of a specific topic. Below are eight comparison tables from the areas of AI, Data Science, IoT, and Cloud Computing. Machine learning explores the study and construction of algorithms that can learn from and make predictions on data. Such algorithms operate by building a model from an example training set of input observations in order to make data-driven predictions or decisions expressed as outputs, rather than following strictly static program instructions. The Internet of Things (IoT) is a system of interrelated computing devices, mechanical and digital machines, objects, animals or people that are provided with unique identifiers (UIDs) and the ability to transfer data over a network without requiring human-to-human or human-to-computer interaction.


[Webinar] Machine Learning Interpretability and Explainable AI with SHAP

#artificialintelligence

Machine learning interpretability and explainable AI concepts are so popular nowadays in data world. Accuracy and interpretability are inversely proportional. Algorithms show high accuracy such as deep learning or gradient boosting machine would have low interpretability. They were totally black boxes. Some industries such as banking have regulations that enforcing you to be explainable.


Deep Learning for Survival Analysis

#artificialintelligence

A pivotal point to be noted is that we are not dealing with a usually labeled dataset. Data for survival analysis is different from standard regression or classification problem. In survival analysis, we are dealing with censored data. Censoring is a form of missing data problem. Whenever we deal with survival analysis, we will get the training data within a study period.


Why is my validation loss lower than my training loss? - PyImageSearch

#artificialintelligence

In this tutorial, you will learn the three primary reasons your validation loss may be lower than your training loss when training your own custom deep neural networks. I first became interested in studying machine learning and neural networks in late high school. Back then there weren't many accessible machine learning libraries -- and there certainly was no scikit-learn. Every school day at 2:35 PM I would leave high school, hop on the bus home, and within 15 minutes I would be in front of my laptop, studying machine learning, and attempting to implement various algorithms by hand. I rarely stopped for a break, more than occasionally skipping dinner just so I could keep working and studying late into the night.


Python Machine Learning: Machine Learning and Deep Learning with Python, scikit-learn, and TensorFlow, 2nd Edition: Amazon.co.uk: Sebastian Raschka, Vahid Mirjalili: 9781787125933: Books

#artificialintelligence

I bought the first version of this book, and now also the second. The new version is very comprehensive. If you are using Python - it's almost a reference. I also like the emphasis on neural networks (and TensorFlow) - which (in my view) is where the Python community is heading. I am also planning to use this book in my teaching at Oxford University. The data pre-processing sections are also good. I found the sequence flow slightly unusual - but for an expert level audience, it's not a major issue.


Heroes of Machine Learning - Top Experts & researchers you should follow

#artificialintelligence

What a time this is to be working in the machine learning field! The last few years have been a dream run for anyone associated with machine learning as there have been a slew of developments and breakthroughs at an unprecedented pace. There's just one thing to keep in mind here – these breakthroughs did not happen overnight. It took years and in some cases, decades, of hard work and persistence. We are used to working with established machine learning algorithms like neural networks and random forest (and so on). We tend to lose sight of the effort it took to make these algorithms mainstream. To actually create them from scratch. The people who lay the groundwork for us – those are the true heroes of machine learning.
