A.I. - Give it a go, it won't bite

If you haven’t had a go before – try it, get your hands (digitally) dirty. You can play without breaking anything (or in some cases even without installing anything). It can help you understand what’s possible. It can help at work, in your AI studies or across the rest of your life. Thankfully these days you don’t have to be a coding supremo to take those first steps. Much of the AI world is moving towards ‘low-code’ or even ‘no-code’, so you can do some pretty impressive AI stuff without leaving the comfort of a friendly app, whether that be on your phone or laptop. Below are a few cool places where you can start exploring the art-of-the-possible – hopefully it will inspire you and be fun, enjoy!

AI Experiments with Google Beginner 
Machine Learning Experiments with GitHub Beginner to Intermediate 
Anaconda, incl. Orange (no code),
Jupyter, Spyder (Python)

Hands-on A.I. exercises

A hurdle for many wanting to gain hands-on experience with AI is setting up a development environment - hours of frustration trying to install Python on Windows, we have all been there! Google's CoLab provides an online Jupyter-like environment with FREE GPU resources where you can experiment to your heart's content. Whilst Google has already provided a number of data science tutorials, one of the great benefits of CoLab is it is possible to open any .ipynb file. Whether you are looking at csv files, images or jumping right into manipulating segy data, there are hundreds of geoscience-specific examples sitting in open GitHub repositories. Here are three notebooks to get you started:

Resources Level 
Analysing thin section compositions Beginner 
An image segmentation example from the
TGS salt detection Kaggle competition
Seismic inversion on the Volve dataset Advanced 
Deep Learning for A.I.

Drastic improvements in hardware performance (GPU) enabled wide spread use of Deep Neural Networks (DNN). Combined with the Convolutional Neural Network (CNN) approach, they complement seismic workflows very well; fault detection, time lapse, inversion seismic-log integration, etc.
In application, careful consideration is advised: non transparency (black box), dependence on training data, outcomes being approximations, sometimes artefacts.
However, because of the multilayered architecture, Deep Learning has proven ‘unreasonably effective’, and improved understanding through research (MIT) will enable novel breakthroughs.

Understanding the U-net

Understanding what happens in images in crucial in the field of machine vision. This problem is broken up into separate but similar topics, such as classification, localization, object detection, semantic segmentation and image segmentation. Without realizing it, geoscientists face similar challenges. Think first break picking or salt interpretation. One of the workhorses for image segmentation problems is the U-net and to get ahead in the field, or simply grasp what your colleagues have developed for you now, one should really
have a basic understanding of this algorithm. Here are three useful links:

Convolutional Networks for Biomedical Image Segmentation (video) Beginner

Deep Learning for A.I. (2)

There is plenty of online training material on Deep Learning. This week we recommend three sources that are very useful for illustrating the practicalities of Deep Learning. They are real fun to use!

TensorFlow playground (already discussed in a different context) provides simple two-dimensional examples of feed-forward neural networks, mostly for classification, and displays the results in a very useful way for somebody who is new to neural networks.

3D Visualization of a Convolutional Neural Network shows the details of the structure and performance of a simple convolutional neural network applied to the classical MNIST dataset.

GAN Lab explains Generative Adversarial Networks, and it really helps understand the interaction between the Generator and the Discriminator.

A.I. Challenges
Historically, the Imagenet Challenge has allowed researchers to develop ground-breaking machine learning methods on open data, enabling reproducible, comparable progress in computer vision.
In geoscience, efforts such as the SEG contest on facies prediction have inspired geoscientists to engage in the field of AI and serve as an excellent entry point for machine learning in geoscience.
Currently ongoing, the FORCE machine learning contest on wells and seismic provides a labeled dataset for facies prediction from wireline logs and a seismic dataset for fault detection.
These and other collaborative challenges will help to inspire future geoscientists and breakthrough technologies in applied machine learning for geoscience.
Explainable A.I.
Explainable Artificial Intelligence (XAI) tries to open the black box of Machine Learning models such that their behavior can be understood by humans. Google Cloud's A.I. Explanations provide a set of tools and frameworks to explain how much each feature in your model contributed to the predicted results for classification and regression tasks. More specifically, SHAP (SHapley Additive exPlanations) is a popular XAI tool based on a solution in cooperative game theory. It can explain the output of any machine learning model with rich visualizations that are friendly for end users.
Quick and easy A.I.
Its' great to try simple examples to see what A.I. can do. There are multiple sites where you can try examples for free and see the results. In the examples below you can upload images and see how ML systems perform classifications and extractions and what data they return.

Google – Image classification

Microsoft – Image classification

When you want to step into run your own more domain specific data (e.g. timeseries or multiple attribute data) then many of the ‘AI Platforms’, like Dataiku and DataRobot allow you to register and run free versions. These systems can run ‘code free’, so if you can use excel then should be able to run those.

These are great ways to explore quickly what A.I. can do and see if it might be relevant for you and your data challenges.
The use of Neural Networks
An exciting area in the deep learning space is the use of neural networks for solving PDEs, equations which dictate the majority of geophysical phenomena. Through tailoring of the cost function, physics-informed neural networks (PINNs) have recently been shown to accurately solve a variety of PDEs. Early attempts in geophysics have been published for solving both the Eikonal and the wave equation. Whilst it is still unclear whether PINNs will reach the precision of our waveform modeling procedures, they are likely to be a fierce competitor with respect to compute time.

The underlying principles of PINNs are detailed in this page.

An example of such a network being to solve the wave equation is illustrated by this paper.

And, for those ready to get your hands dirty, checkout the DeepXDE python library.
Interpretable Machine Learning
Essential for business confidence and in critical decisions is the ability not just to provide accuracy with Machine Learning but also the why and how.

In short, interpretability means to determine a representation in terms of human understanding of the results; with few parameters (i.e. linear regression) this is straightforward. At the other end, Deep Neural Networks (DNN) are effective in finding subtle relationships among many features but are hard to interpret.

Recently developed methods to analyze DNN include LIME (Local Interpretable Model-Agnostic Explanations) and DeepLIFT (Deep Learning Important Features)

With using alternatives to DNN, the common belief is that interpretability goes at the expense of accuracy, on which assertion some disagree with.
