#artificialintelligence

We are a community of Machine Learning Researchers and Engineers, working to help Twitter leverage ML through a range of systems such as recommendations, safety, abuse, content understanding, ads and more. We operate at scale whilst ensuring fair and ethical use of our models and data. We work collaboratively, often embedding among product teams, looking to apply the expertise of the individuals to improve our products and unlock new capabilities. We encourage publishing papers, but they are not the end goal, rather a by-product of us doing interesting work - the aim is to make a real-world impact! The Learning Methods Research Team, part of Cortex Applied Research, enables ML applications across our platform (e.g.


Summit: Benchmarking Machine Learning Methods for Reaction Optimisation

#artificialintelligence

In the fine chemicals industry, reaction screening and optimisation are essential to development of new products. However, this screening can be extremely time and labor intensive, especially when intuition is used. Machine learning offers a solution through iterative suggestions of new experiments based on past experimental data, but knowing which machine learning strategy to apply in a particular case is still difficult. Here, we develop chemically-motivated virtual benchmarks for reaction optimisation and compare several strategies on these benchmarks. The benchmarks and strategies are encompassed in an open source framework named Summit.


Comparative Assessment of Snowfall Retrieval from Microwave Humidity Sounders using Machine Learning Methods

#artificialintelligence

Accurate quantification of snowfall rate from space is important, but has remained difficult. Four years (2007‐2010) of NOAA‐18 Microwave Humidity Sounder (MHS) data are trained and tested with snowfall estimates from coincident CloudSat Cloud Profiling Radar (CPR) observations using several machine learning methods. Among the studied methods, random forest using MHS (RF‐MHS) is found the best for both detection and estimation of global snowfall. The RF‐MHS estimates are tested using independent years of coincident CPR snowfall estimates and compared with snowfall rates from Modern‐Era Retrospective analysis for Research and Applications Version 2 (MERRA‐2), Atmospheric Infrared Sounder (AIRS), and MHS Goddard Profiling Algorithm (GPROF). It was found that RF‐MHS algorithm can detect global snowfall with approximately 90% accuracy and a Heidke skill score of 0.48 compared to independent CloudSat samples. The surface wet bulb temperatures, brightness temperatures at 190 GHz, and 157 GHz channels are found to be the most important features to delineate snowfall areas.


Glia Integrates Boost.ai to Offer AI-Powered Self-Learning Virtual Agents

#artificialintelligence

Glia Customers Can Use Boost.ai's Boost.ai, a global leader in artificial intelligence for Fortune 1000 companies, has announced a partnership with Glia, a leading provider of Digital Customer Service, to integrate Boost.ai's The integration means Glia customers can build AI-powered self-learning virtual agents using Boost.ai's "Self-learning AI from Boost.ai makes it possible for Glia's customers to create specially developed and finely tuned virtual agents that are even more valuable when coordinated by the Glia platform throughout the course of a customer engagement," said Henry Iversen, co-founder and CCO at Boost.ai. "This might involve filling out a loan application or opening a new bank account, where seamless transition between channels including social, SMS, webchat, and voice is assistive to both customers and agents alike."


What Is Deep Active Learning: Challenges and Applications

#artificialintelligence

According to NVIDIA, if humans were to label the data for a 100-car fleet driving for eight hours a day, they would require more than 1 million labellers. It takes autonomous vehicles nearly 11 billion miles of driving to perform just 20% better than a human. Real-world problems that machine learning models encounter come with uncertainties and deficiencies. So, keeping the model updated, in other words, making the model smarter even with incoming unknown data is a challenge. This is where Active learning (AL) comes into the picture.


Using AI to predict student performance!

#artificialintelligence

Let's see if we can forecast Timmy's math grade using a Random Decision Forest… From virtual teaching assistants named Jill Watson and Happy Numbers to essay grading software like Gradescope, artificial intelligence has started seeping into schools, colleges, and universities. Although it's interesting to learn about the benefits and detriments of this development, I'm more fascinated with the following question: how can we use artificial intelligence and machine learning to improve student success? My first stab at this broad question was seeing if we could predict student performance based on student/parent participation. From my experience, teachers often encourage students to participate in class discussions, activities, and projects. In addition, schools usually encourage parents to take part in their child's education through parent teacher conferences, surveys, and meetings.


Central University of Technology introduces Artificial Intelligence university programme in partnership with Microsoft, Free State Government, Gijima

#artificialintelligence

Central University of Technology, South Africa, is introducing an Artificial Intelligence university programme powered by Microsoft. To firstly skill employees with the in-demand skill and secondly address the demand for the skill in the province and South Africa in general. The Artificial Intelligence university programme is developed by Microsoft and will be delivered by Microsoft Partner Gijima. The initiative is also in partnership with the Free State Provincial Government. It will comprise of a 12-month blended learning model of self-study, online learning, classroom instructor-led training and a flipped classroom.


[D] Utilizing Uncertainty Estimation to increase Auto-Label efficiency for Active Learning

#artificialintelligence

I approved this post because even if you ignore the "Superb AI"-specific aspects, I think this post has value in providing an overview of uncertainty estimation methods. In other words, if you remove section 5, would this still be an interesting article? I do agree that it's somewhat disappointing that this blog post is structured as "here are the existing methods, which suck. Pay us to use our method instead!". However, I think that's reflected simply in the upvotes and general reaction. If the blog was instead, "here are the existing methods.


A Survey of Deep Active Learning

#artificialintelligence

Active learning (AL) attempts to maximize the performance gain of the model by marking the fewest samples. Deep learning (DL) is greedy for data and requires a large amount of data supply to optimize massive parameters, so that the model learns how to extract high-quality features. In recent years, due to the rapid development of internet technology, we are in an era of information torrents and we have massive amounts of data. In this way, DL has aroused strong interest of researchers and has been rapidly developed. Compared with DL, researchers have relatively low interest in AL. This is mainly because before the rise of DL, traditional machine learning requires relatively few labeled samples.


13 Algorithms and 4 Learning Methods of Machine Learning

#artificialintelligence

According to the similarity of the function and form of the algorithm, we can classify the algorithm, such as tree-based algorithm, neural network-based algorithm, and so on. Of course, the scope of machine learning is very large, and it is difficult for some algorithms to be clearly classified into a certain category. Regression algorithm is a type of algorithm that tries to explore the relationship between variables by using a measure of error. Regression algorithm is a powerful tool for statistical machine learning. In the field of machine learning, when people talk about regression, sometimes they refer to a type of problem and sometimes a type of algorithm.
