I've had a number of questions about setting up a machine learning/artificial intelligence environment on an Apple Silicon Mac. So I've tried to write a step by step guide.

Setting up ML and AI tools on Apple Silicon, using home-brew and conda to install and manage compatibility and dependences.

I've also created a .yml file that you can use instead of going through all the steps.

There are a couple of example Jupyter notebooks that give a starting point for trying things out.

I'm very much aware that this is a bit of a moving target at the moment so comments/suggestions are much appreciated.

Combining robotics and Machine Learning for accelerated drug discovery – Dr Tom Fleming (Arctoris)

Abstract: Artificial intelligence has an increasing impact on drug discovery and development, offering opportunities to identify novel targets, hit, and lead-like compounds in accelerated timeframes. However, the success of any AI/ ML model depends on the quality of the input data, and the speed with which in silico predictions can be validated in vitro. The talk will cover laboratory automation and robotics and the benefits they offer in terms of quality and speed of data generation synergise with AI/ ML-powered drug discovery approaches. The talk will cover some of the general trends in the industry, and also highlight successfully implemented case studies that show the how the combination of robotics and AI/ ML lead to accelerated project timelines and superior research outputs.

Bio: Tom Fleming MChem is the COO of biotech platform company Arctoris, which he co-founded in Oxford in 2016. Tom’s background is in cancer research, having worked in academia as well as at leading CROs and pharmaceutical corporations. A chemical biologist by training, he has unique insights into preclinical drug discovery, including the critical steps from target identification and high-throughput screening up to lead optimization. Tom was a Fellow of the Royal Commission of 1851 at the University of Oxford, and is a SME Leader of the Royal Academy of Engineering.

Machine Learning and AI for Drug Design – Professor Ola Engkvist (AstraZeneca & Chalmers University)

Abstract: Artificial Intelligence has become impactful during the last few years in chemistry and the life sciences, pushing the scientific boundaries forward as exemplified by the recent success of AlphaFold2. In this presentation I will provide an overview of how AI have impacted drug design in the last few years, where we are now and what progress we can reasonably expect in the coming years. The presentation will have a focus on deep learning based molecular de novo design, however, also aspects of synthesis prediction, molecular property predictions and chemistry automation will be covered.

Bio: Dr Ola Engkvist is head of Molecular AI in Discovery Sciences, AstraZeneca R&D. He did his PhD in computational chemistry at Lund University followed by a postdoc at Cambridge University. After working for two biotech companies he joined AstraZeneca in 2004. He currently lead the Molecular AI department, where the focus is to develop novel methods for ML/AI in drug design , productionalize the methods and apply the methods to AstraZeneca’s small molecules drug discovery portfolio. His main research interests are deep learning based molecular de novo design, synthetic route prediction and large scale molecular property predictions. He has published over 100 peer-reviewed scientific publications. He is adjunct professor in machine learning and AI for drug design at Chalmers University of Technology and a trustee of Cambridge Crystallographic Data Center.

Accelerating design of organic materials with machine learning and AI – Professor Olexandr Isayev (Carnegie Mellon University)

Abstract: Deep learning is revolutionizing many areas of science and technology, particularly in natural language processing, speech recognition, and computer vision. In this talk, we will provide an overview of the latest developments of machine learning and AI methods and application to the problem of drug discovery and development at Isayev’s Lab at CMU. We identify several areas where existing methods have the potential to accelerate materials research and disrupt more traditional approaches. First we will present a deep learning model that approximates the solution of Schrodinger equation. We introduce the AIMNet-NSE (Neural Spin Equilibration) architecture, which can predict molecular energies for an arbitrary combination of molecular charge and spin multiplicity. The AIMNet-NSE model allows to fully bypass QM calculations and derive the ionization potential, electron affinity, and conceptual Density Functional Theory quantities like electronegativity, hardness, and condensed Fukui functions. We show that these descriptors, along with learned atomic representations, could be used to model chemical reactivity through an example of regioselectivity in electrophilic aromatic substitution reactions. Second, we proposed a novel ML-guided materials discovery platform that combines synergistic innovations in automated flow synthesis and automated machine learning (AutoML) method development. A software-controlled, continuous polymer synthesis platform enables rapid iterative experimental–computational cycles that resulted in the synthesis of hundreds of unique copolymer compositions within a multi-variable compositional space. The non-intuitive design criteria identified by ML, which was accomplished by exploring less than 0.9% of overall compositional space, upended conventional wisdom in the design of 19F MRI agents and led to the identification of >10 copolymer compositions that outperformed state-of-the-art materials.

Bio: Olexandr Isayev is an Assistant Professor at the Department of Chemistry at Carnegie Mellon University. In 2008, Olexandr received his Ph.D. in computational chemistry. He was Postdoctoral Research Fellow at the Case Western Reserve University and a scientist at the government research lab. During 2016-2019 he was a faculty at UNC Eshelman School of Pharmacy, the University of North Carolina at Chapel Hill. Olexandr received the “Emerging Technology Award” from the American Chemical Society (ACS) and the GPU computing award from NVIDIA. The research in his lab focuses on connecting artificial intelligence (AI) with chemical sciences.

Registration is now open for the AI3SD & RSC-CICAG Protein Structure Prediction Conference. This online event looks like it will a brilliant meeting with a fantastic lineup of speakers. June 16 @ 9:45 am - June 17 @ 5:00 pm Free

Registration here Eventbrite Link: https://ai3sd-cicag-protein-structure-prediction.eventbrite.co.uk.

The challenge of protein structure prediction has advanced significantly in recent years, yet translation into impact, particularly in drug discovery, remains open. Furthermore, while we as a community have advanced in predicting protein structures, they offer only static snapshots, and do not yet consider effectively the protein dynamics and conformational change. Bringing together scientists working in this area, and those who work with the resulting data, this conference is intended as a pulse check on the status of the field and where we will start seeing impact and improvements for human benefit. The two days will contain a number of talks from speakers who are key opinion leaders in the field, together with an opportunity to present short talks and posters to a wider audience. Day 1 will finish with an online social event (separate links will be sent out to register for this closer to the time) and Day 2 and will close with a panel discussion by the speakers, which is intended to be provocative.

Current invited speakers include: Professor John Moult (University of Maryland), Dr Chris De Graaf (Sosei Heptares), Professor Debora Marks (Harvard University), Professor Cecilia Clementi (Freie Universität Berlin), Professor Aleksej Zelezniak (Chalmers University of Technology), Dr Oscar Méndez-Lucio (Janssen Pharmaceuticals), Professor Charlotte Deane (University of Oxford), Professor Tudor Oprea (University of New Mexico), Dr Derek Lowe (Novartis), Professor Stephen Burley (RCSB PDB, Rutgers University, USCD).

After creating MolSeeker and iBabel4 I've been investigating the use of Swift and in particular the open-source use.

Swift.org provides a nice introduction and overview, it also highlights the Google Summer of Code Swift projects which are a fabulous way for students to get involved.

The Google Swift for TensorFlow group have been very active, and Tyrolabs have recently posted a detailed summary, including a comparison with other languages.

Two years ago, a small team at Google started working on making Swift the first mainstream language with first-class language-integrated differentiable programming capabilities. The scope and initial results of the project have been remarkable, and general public usability is not very far off.

They have now provided support for Jupyter notebooks https://github.com/google/swift-jupyter

There is also an interesting blog post here fast.ai.

IBM also seem to be using swift https://developer.ibm.com/technologies/swift/ and are highlighting leveraging Watson.

Developers can take advantage of the Watson Developer Cloud’s Swift SDK to easily build Watson-powered applications for iOS or Linux platforms. Leverage the power of Watson’s advanced artificial intelligence, machine learning, and deep learning techniques to understand unstructured data and engage with users in new ways.

Since Swift is a relatively new language it is worth looking at the ongoing evolution.

One of the highlights for me at the recent 2nd RSC-BMCS / RSC-CICAG Artificial Intelligence in Chemistry in Cambridge was the work of Adrian Roitberg and Olexandr Isayev et al on Approaching coupled cluster accuracy with a general-purpose neural network potential through transfer learning DOI.

Here we train a general-purpose neural network potential (ANI- 1ccx) that approaches CCSD(T)/CBS accuracy on benchmarks for reaction thermochemistry, isomerization, and drug-like molecular torsions. This is achieved by training a network to DFT data then using transfer learning techniques to retrain on a dataset of gold standard QM calculations (CCSD(T)/CBS) that optimally spans chemical space. The resulting potential is broadly applicable to materials science, biology, and chemistry, and billions of times faster than CCSD(T)/CBS calculations.

The presentation was really compelling and really looks like an example where AI can be truly transformational. The good news is the code is all freely available on Github https://github.com/isayev/ASE_ANI, the bad news is that it "Works only under Ubuntu variants of Linux with a NVIDIA GPU" and Python binaries built for python 3.6 and CUDA 9.2.

In the past I would have stopped there but with the increasing number of external GPU and a NVIDIA CUDA Installation Guide for Mac OS X I'm wondering if there might be a path forward. I'd be very interested to hear about experiences with external GPU with NVIDIA graphics cards and using the CUDA toolkit on a Mac.

Update

Olexandr emailed me to to mention they have a pure Python version https://github.com/aiqm/torchani this will run on Mac however there is no GPU acceleration.

TorchANI is a pytorch implementation of ANI. It is currently under alpha release, which means, the API is not stable yet. If you find a bug of TorchANI, or have some feature request, feel free to open an issue on GitHub, or send us a pull requests

Also stumbled across the paper

We are already thinking about a possible 3rd meeting, and any feedback would be much appreciated.

 

Since the Fortran on a Mac is one of the most popular pages on the site I thought I'd mention this paper, submitted to ACM SIGPLAN Fortran Forum, I've just come across.

A parallel Fortran framework for neural networks and deep learning DOI.

This paper describes neural-fortran, a parallel Fortran framework for neural networks and deep learning. It features a simple interface to construct feed-forward neural networks of arbitrary structure and size, several activation functions, and stochastic gradient descent as the default optimization algorithm. Neural-fortran also leverages the Fortran 2018 standard collective subroutines to achieve data-based parallelism on shared- or distributed-memory machines. First, I describe the implementation of neural networks with Fortran derived types, whole-array arithmetic, and collective sum and broadcast operations to achieve parallelism. Second, I demonstrate the use of neural-fortran in an example of recognizing hand-written digits from images. Finally, I evaluate the computational performance in both serial and parallel modes. Ease of use and computational performance are similar to an existing popular machine learning framework, making neural-fortran a viable candidate for further development and use in production.

 

I was just looking through the delegate registrations for the 2nd RSC-BMCS / RSC-CICAG Artificial Intelligence in Chemistry Meeting taking place in Cambridge, UK 2nd to 3rd September 2019. We now have significantly more registrations than the first meeting, participants are coming from 16 different countries and whilst the UK and US predominate there are many participants from the rest of Europe and even some from Japan and Korea. There are 90 different organisations represented and I'm delighted to see there are over 20 student attendees, many from overseas. A number of students are presenting posters and the lineup of people taking part in the flash poster session can be found here.

Registration is still open for what looks like what will be another outstanding meeting.

A few people have said they are planning a visit to Cambridge for a holiday around the meeting and have asked for suggestions of things to do. Visit Cambridge is a good place to start.

 

This looks really interesting

TabNine is an autocompleter that helps you write code faster by adding a deep learning model which significantly improves suggestion quality. You can see videos at the link above.

There has been a lot of hype about deep learning in the past few years. Neural networks are state-of-the-art in many academic domains, and they have been deployed in production for tasks such as autonomous driving, speech synthesis, and adding dog ears to human faces. Yet developer tools have been slow to benefit from these advances

Deep TabNine is trained on around 2 million files from GitHub. During training, its goal is to predict each token given the tokens that come before it. To achieve this goal, it learns complex behaviour, such as type inference in dynamically typed languages.

An interesting idea, my only concern is the quality of code in the training set.

 

The 2nd RSC-BMCS / RSC-CICAG Artificial Intelligence in Chemistry meetings is filling up fast, however there are still 6 bursaries unallocated. The closing date for applications is 15 July. The bursaries are available up to a value of £250, to support registration, travel and accommodation costs for PhD and post-doctoral applicants studying at European academic institutions.

When this paper first appeared on the arXiv preprint server "Molecular Transformer - A Model for Uncertainty-Calibrated Chemical Reaction Prediction https://arxiv.org/abs/1811.02633 it generated considerable interest.

Organic synthesis is one of the key stumbling blocks in medicinal chemistry. A necessary yet unsolved step in planning synthesis is solving the forward problem: given reactants and reagents, predict the products. Similar to other work, we treat reaction prediction as a machine translation problem between SMILES strings of reactants-reagents and the products. We show that a multi-head attention Molecular Transformer model outperforms all algorithms in the literature, achieving a top-1 accuracy above 90% on a common benchmark dataset. Our algorithm requires no handcrafted rules, and accurately predicts subtle chemical transformations. Crucially, our model can accurately estimate its own uncertainty, with an uncertainty score that is 89% accurate in terms of classifying whether a prediction is correct. Furthermore, we show that the model is able to handle inputs without reactant-reagent split and including stereochemistry, which makes our method universally applicable.

I just noticed that it had been recently updated.

If you are interested in this exciting area of chemistry you might be interested to know the code is available on GitHub and the trained model is available online https://rxn.res.ibm.com.

One of the authors, Alpha Lee, is speaking at the 2nd Artificial Intelligence in Chemistry Meeting #AIChem19, 2nd to 3rd September 2019, Fitzwilliam College, Cambridge, UK. You can register for the meeting here if you would like to hear first hand about this technology.

The full lineup of speakers are here. Also remember there are bursaries available for the meeting.

I posted a poll on twitter

Looking at abstracts for the AI in Chemistry Meeting … many mine published data. The quality of the public data is obviously critical for good models. Is this something the AI community should be concerned about or get involved with to improve the quality of the literature?

The results are now in and interestingly despite nearly 2.5K impressions only 28 people voted. Of those that voted the overwhelming majority feel that AI scientists should help to improve the quality of the literature.

The comments associated with the tweet are interesting, certainly many machine learning models are robust enough to accommodate some poor data but I think there is a deeper concern.

Elisabeth Bik has regularly flagged questionable publications, unfortunately these are not always detected before their influence has been propagated through the literature.

For a very detailed example look at 5-HTTLPR: A POINTED REVIEW looking at an unusual version of the serotonin transporter gene 5-HTTLPR.

I've heard of many examples of scientists being unable to reproduce literature findings, usually little happens, however Amgen were able to reproduce only 6 out of 53 'landmark' studies and they published their findings.

How many times do scientists assume failure to reproduce published findings is their error?

There have been several studies looking at the possible causes of the failure to reproduce work, in 2011, an evaluation of 246 antibodies used in epigenetic studies found that one-quarter failed tests for specificity, meaning that they often bound to more than one target. Four antibodies were perfectly specific — but to the wrong target Reproducibility crisis: Blame it on the antibodies.

See also "The antibody horror show: an introductory guide for the perplexed" DOI

Colourful as this may appear, the outcomes for the community are uniformly grim, including badly damaged scientific careers, wasted public funding, and contaminated literature.

If you are mining literature data to predict novel drug targets then Caveat emptor.

 

 

I was just sent details of a Special Issue "Machine Learning with Python for the journal Information.

We live in this day and age where quintillions of bytes of data are generated and collected every day. Around the globe, researchers and companies are leveraging these vast amounts of data in countless application areas, ranging from drug discovery to improving transportation with self-driving cars.As we all know, Python evolved into the lingua franca of machine learning and artificial intelligence research over the last couple of years. What makes Python particularly attractive for us researchers is that it gives us access to a cohesive set of tools for scientific computing and is easy to teach and learn. Also, as a language that bridges many different technologies and different fields, Python fosters interdisciplinary collaboration. And besides making us more productive in our research, sharing tools we develop in Python has the potential to reach a wide audience and benefit the broader research community.

This special issue is now open for submission.

 

A Twitter poll can we trust published data and should AI community be involved?

This repository contains TensorFlow models written in Swift.

Swift for TensorFlow is a next-generation platform for machine learning, incorporating the latest research across machine learning, compilers, differentiable programming, systems design, and beyond. This is an early-stage project: it is not feature-complete nor production-ready, but it is ready for pioneers to try in projects, give feedback, and help shape the future!

This is the second public release of Swift for TensorFlow, available across Google Colaboratory, Linux, and macOS.

 

I ran a poll last week asking "In which area is Artificial Intelligence likely to most impact Chemistry?" And we now have the results.

Whilst Molecular Design was the most popular choice it was interesting to see that all options were well supported. This suggests that there are opportunities for artificial intelligence to have an impact in many facets of chemistry. I'm delighted to see this since this was part of the thinking behind the AI in Chemistry meeting and I think the line up of speakers will have something for everyone.

In June 2018 the First RSC-BMCS / RSC-CICAG Artificial Intelligence in Chemistry meeting was held in London. This proved to enormously popular, there were more oral abstracts and poster submissions than we had space for and was so over-subscribed we could have filled a venue double the size.

Planning for the second meeting is now in full swing, and it will be held in Cambridge 2-3 September 2019.

Event : 2nd RSC-BMCS / RSC-CICAG Artificial Intelligence in Chemistry
Dates : Monday-Tuesday, 2nd to 3rd September 2019
Place : Fitzwilliam College, Cambridge, UK
Websites : Event website, and RSC website.

Twitter #AIChem19

Applications for both oral and poster presentations are welcomed. Posters will be displayed throughout the day and applicants are asked if they wished to provide a two-minute flash oral presentation when submitting their abstract. The closing dates for submissions are:

• 31st March for oral and
• 5th July for poster

Full details can be found on the Event website,

 

Comparison of different algorithms is an under researched area, this publication looks like a useful starting point.

GuacaMol: Benchmarking Models for De Novo Molecular Design

De novo design seeks to generate molecules with required property profiles by virtual design-make-test cycles. With the emergence of deep learning and neural generative models in many application areas, models for molecular design based on neural networks appeared recently and show promising results. However, the new models have not been profiled on consistent tasks, and comparative studies to well-established algorithms have only seldom been performed. To standardize the assessment of both classical and neural models for de novo molecular design, we propose an evaluation framework, GuacaMol, based on a suite of standardized benchmarks. The benchmark tasks encompass measuring the fidelity of the models to reproduce the property distribution of the training sets, the ability to generate novel molecules, the exploration and exploitation of chemical space, and a variety of single and multi-objective optimization tasks. The benchmarking framework is available as an open-source Python package.

Source code : https://github.com/BenevolentAI/guacamol.

The easiest way to install guacamol is with pip:

pip install git+https://github.com/BenevolentAI/guacamol.git#egg=guacamol --process-dependency-links

guacamol requires the RDKit library (version 2018.09.1.0 or newer).

An interesting paper uses 1,808,938 reactions from the patent literature as a training set to build a model to predict reactions.

There is an intuitive analogy of an organic chemist's understanding of a compound and a language speaker's understanding of a word. Consequently, it is possible to introduce the basic concepts and analyze potential impacts of linguistic analysis to the world of organic chemistry. In this work, we cast the reaction prediction task as a translation problem by introducing a template-free sequence-to-sequence model, trained end-to-end and fully data-driven. We propose a novel way of tokenization, which is arbitrarily extensible with reaction information. With this approach, we demonstrate results superior to the state-of-the-art solution by a significant margin on the top-1 accuracy. Specifically, our approach achieves an accuracy of 80.1% without relying on auxiliary knowledge such as reaction templates. Also, 66.4% accuracy is reached on a larger and noisier dataset.

There is also a brief video describing the work.
