Electronically excited states of molecules are at the heart of photochemistry, photophysics, as well as photobiology and also play a role in material science. Their theoretical description requires highly accurate quantum chemical calculations, which are computationally expensive. In this review, we focus on how machine learning is employed not only to speed up such excited-state simulations but also how this branch of artificial intelligence can be used to advance this exciting research field in all its aspects. Discussed applications of machine learning for excited states include excited-state dynamics simulations, static calculations of absorption spectra, as well as many others. In order to put these studies into context, we discuss the promises and pitfalls of the involved machine learning techniques. Since the latter are mostly based on quantum chemistry calculations, we also provide a short introduction into excited-state electronic structure methods, approaches for nonadiabatic dynamics simulations and describe tricks and problems when using them in machine learning for excited states of molecules.

As machine learning is increasingly deployed in high-stakes contexts affecting people's livelihoods, there have been growing calls to open the black box and to make machine learning algorithms more explainable. Providing useful explanations requires careful consideration of the needs of stakeholders, including end-users, regulators, and domain experts. Despite this need, little work has been done to facilitate inter-stakeholder conversation around explainable machine learning. To help address this gap, we conducted a closed-door, day-long workshop between academics, industry experts, legal scholars, and policymakers to develop a shared language around explainability and to understand the current shortcomings of and potential solutions for deploying explainable machine learning in service of transparency goals. We also asked participants to share case studies in deploying explainable machine learning at scale. In this paper, we provide a short summary of various case studies of explainable machine learning, lessons from those studies, and discuss open challenges.

In this "Azure Cosmos DB for AI Engineers" blog post, you will learn how AI Engineers can use Azure Cosmos DB to support their AI solutions, focusing on storing and analyzing unstructured or semi-structured data. AI Engineers design and implement intelligent apps and agents that simulate human perception using cognitive services, machine learning, and knowledge mining. Typical scenarios are anomaly detection, language understanding, text mining, search, among others. Let's see why Azure Cosmos DB is the perfect database for AI Architectures on Azure. Cognitive Services bring AI within reach of every developer--without requiring machine-learning expertise.

The presence of outliers in a classification or regression dataset can result in a poor fit and lower predictive modeling performance. Identifying and removing outliers is challenging with simple statistical methods for most machine learning datasets given the large number of input variables. Instead, automatic outlier detection methods can be used in the modeling pipeline and compared, just like other data preparation transforms that may be applied to the dataset. In this tutorial, you will discover how to use automatic outlier detection and removal to improve machine learning predictive modeling performance. Discover data cleaning, feature selection, data transforms, dimensionality reduction and much more in my new book, with 30 step-by-step tutorials and full Python source code.

In doubt about what is the best learning rate for your model? This little guy can help you solve it! Based on a function, you can modify this parameter without having to interrupt model training! Let's look at our code. Well, this callback only needs a single function to work; The function itself needs the actual epoch and learning rate as parameters, but don't worry, your callback captures these values directly from the model.fit

You keep hearing about machine learning and artificial intelligence and how they revolutionize the world we live in. You want to learn more. You have basic understanding of Python and you are decent in math. You're going to learn hands-on machine learning with scikit-learn, a Python library for machine learning. Since this is a hands-on course, you will be working your way through with Python and Jupyter notebooks.

It is difficult, perhaps, to link this to neural networks, but the basic intuition of calculus is achieved. If you are looking for a more full treatment of this branch of mathematics, you will want to seek out some more robust learning tools. Here are 3 courses and a textbook to help out, all from MIT's Open Courseware initiative, which will cover everything you need to know about calculus to understand deep learning -- and far beyond.
