ALICE is an Artificial Intelligence project initiated by Microsoft Research, known as Automated Learning and Intelligence for Causation and Economics. The project focuses on leveraging state-of-the-art machine learning techniques combined with econometrics to enhance economic decision-making processes. [1]
The primary goal of ALICE is to measure causation in economic systems, which is crucial for making informed policy decisions. This involves understanding the reasons behind the movements within complex economies. The project builds on Microsoft's long history of integrating Economics and Computer Science, bringing together researchers from various fields such as Social Science, AI, and Machine Learning. The ALICE team aims to scale up the adaptation of existing ML technologies for economic applications and develop new deep learning architectures for causal inference. [1] Their research addresses practical policy-relevant applications, including demand estimation, price optimization, effectiveness of advertising, sales strategies, and designing incentives for desirable healthcare and education outcomes. This endeavor aims to democratize economic research using AI, while simultaneously advancing the frontier of AI through economic theory. [2]
One notable aspect of the ALICE project is the collaboration with TripAdvisor. A case study between Microsoft Research and TripAdvisor explored the use of causal AI for customer segmentation, [3] This partnership emerged from a chance encounter between data scientists from both organizations, leading to a joint effort in understanding the impact of a membership model on user engagement. By leveraging an A/B test, the ALICE team developed a new statistical method to measure the direct effects of membership on engagement. This approach, which builds upon traditional instrumental variables techniques, revealed significant variation in user engagement based on the platform used and pages visited by the user. [3]
The collaboration resulted in valuable insights for TripAdvisor. The ALICE team found that membership positively affects user engagement, with significant variation among users. The major drivers of this variation included the platform from which the user accessed TripAdvisor and the pages they visited before the experiment. The key innovation was developing an ML-based method for estimating heterogeneous causal effects in A/B tests with non-compliance, which allows for complex individual-level differences in both compliance and the intervention's effect. [3]
The methodology has been implemented in the EconML software package, an open-source Python library developed by the ALICE team. EconML applies machine learning techniques to estimate individualized causal responses from observational or experimental data. [2]
Principal Economist Eleanor Dillon currently leads the ALICE project at the Microsoft Research Lab - New England. [1]
A chatbot is a software application or web interface that is designed to mimic human conversation through text or voice interactions. Modern chatbots are typically online and use generative artificial intelligence systems that are capable of maintaining a conversation with a user in natural language and simulating the way a human would behave as a conversational partner. Such chatbots often use deep learning and natural language processing, but simpler chatbots have existed for decades.
A CAPTCHA is a type of challenge–response test used in computing to determine whether the user is human in order to deter bot attacks and spam.

Artificial intelligence (AI) has been used in applications throughout industry and academia. Similar to electricity or computers, AI serves as a general-purpose technology that has numerous applications. Its applications span language translation, image recognition, decision-making, credit scoring, e-commerce and various other domains. AI which accommodates such technologies as machines being equipped perceive, understand, act and learning a scientific discipline.

Endpoint security or endpoint protection is an approach to the protection of computer networks that are remotely bridged to client devices. The connection of endpoint devices such as laptops, tablets, mobile phones, and other wireless devices to corporate networks creates attack paths for security threats. Endpoint security attempts to ensure that such devices follow compliance to standards.
Semantic Scholar is a research tool for scientific literature powered by artificial intelligence. It is developed at the Allen Institute for AI and was publicly released in November 2015. Semantic Scholar uses modern techniques in natural language processing to support the research process, for example by providing automatically generated summaries of scholarly papers. The Semantic Scholar team is actively researching the use of artificial intelligence in natural language processing, machine learning, human–computer interaction, and information retrieval.
Lawbots are a broad class of customer-facing legal AI applications that are used to automate specific legal tasks, such as document automation and legal research. The terms robot lawyer and lawyer bot are used as synonyms to lawbot. A robot lawyer or a robo-lawyer refers to a legal AI application that can perform tasks that are typically done by paralegals or young associates at law firms. However, there is some debate on the correctness of the term. Some commentators say that legal AI is technically speaking neither a lawyer nor a robot and should not be referred to as such. Other commentators believe that the term can be misleading and note that the robot lawyer of the future won't be one all-encompassing application but a collection of specialized bots for various tasks.
Explainable AI (XAI), often overlapping with interpretable AI, or explainable machine learning (XML), either refers to an artificial intelligence (AI) system over which it is possible for humans to retain intellectual oversight, or refers to the methods to achieve this. The main focus is usually on the reasoning behind the decisions or predictions made by the AI which are made more understandable and transparent. XAI counters the "black box" tendency of machine learning, where even the AI's designers cannot explain why it arrived at a specific decision.
ML.NET is a free software machine learning library for the C# and F# programming languages. It also supports Python models when used together with NimbusML. The preview release of ML.NET included transforms for feature engineering like n-gram creation, and learners to handle binary classification, multi-class classification, and regression tasks. Additional ML tasks like anomaly detection and recommendation systems have since been added, and other approaches like deep learning will be included in future versions.
Automated Artificial Intelligence (AutoAI) is a variation of the automated machine learning or AutoML technology, which extends the automation of model building towards automation of the full life cycle of a machine learning model. It applies intelligent automation to the task of building predictive machine learning models by preparing data for training and identifying the best type of model for the given data. then choosing the features or columns of data that best support the problem the model is solving. Finally, automation evaluates a variety of tuning options to reach the best result as it generates, then ranks, model-candidate pipelines. The best performing pipelines can be put into production to process new data, and deliver predictions based on the model training. Automated artificial intelligence can also be applied to making sure the model doesn't have inherent bias and automating the tasks for continuous improvement of the model. Managing an AutoAI model requires frequent monitoring and updating, managed by a process known as model operations or ModelOps.
