Deep neural networks have demonstrated their capability to learn control policies for a variety of tasks. However, these neural network-based policies have been shown to be susceptible to exploitation by adversarial agents. Therefore, there is a need to develop techniques to learn control policies that are robust against adversaries. We introduce Adversarially Robust Control (ARC), which trains the protagonist policy and the adversarial policy end-to-end on the same loss. The aim of the protagonist is to maximise this loss, whilst the adversary is attempting to minimise it. We demonstrate the proposed ARC training in a highway driving scenario, where the protagonist controls the follower vehicle whilst the adversary controls the lead vehicle. By training the protagonist against an ensemble of adversaries, it learns a significantly more robust control policy, which generalises to a variety of adversarial strategies. The approach is shown to reduce the amount of collisions against new adversaries by up to 90.25%, compared to the original policy. Moreover, by utilising an auxiliary distillation loss, we show that the fine-tuned control policy shows no drop in performance across its original training distribution.

Raipur: The All India Institute of Medical Sciences Raipur in Chhattisgarh organized a ''Continuing Medical Education'' (CME) seminar on Artificial Intelligence in healthcare, with 625 delegates taking part, officials said on Sunday. The aim was to find out how AI-based technology could be accommodated in diagnostics and patient management while taking care of accountability, transparency and privacy issues. AIIMS Raipur president Professor George A D''Souza said AI was being used in diagnostics, surgery, patient management, drug discovery and administration as well as fields like dermatology, ophthalmology and radiology. "We have to address several issues and safeguard the interests of different stakeholders while using AI in healthcare. These include privacy, consent of the patient, interpretation of data, accountability and transparency," he said.

Have you ever used the following three lines of code, or some variation of them, in your ML scripts and had no clue what their purpose was? If so, this article should aid in clearing up and simplifying the truth behind these three tremendously important lines of code. Before I dive into the explanation, I want to clarify some prerequisite knowledge that is necessary to understand the contents of this article. Firstly, a working understanding of backpropagation and gradient descent is highly suggested. And by highly suggested, I mean mandatory. I know that both these concepts are taboo for coders who just want to code, but there is a lot of merit in understanding what is going on behind the scenes of your ML scripts.

Gradient descent is an optimization algorithm that follows the negative gradient of an objective function in order to locate the minimum of the function. A limitation of gradient descent is that it uses the same step size (learning rate) for each input variable. This can be a problem on objective functions that have different amounts of curvature in different dimensions, and in turn, may require a different sized step to a new point. Adaptive Gradients, or AdaGrad for short, is an extension of the gradient descent optimization algorithm that allows the step size in each dimension used by the optimization algorithm to be automatically adapted based on the gradients seen for the variable (partial derivatives) seen over the course of the search. In this tutorial, you will discover how to develop the gradient descent with adaptive gradients optimization algorithm from scratch.

Fundamentals of Machine Learning in Finance Fundamentals of Machine Learning in Finance will provide more at-depth view of supervised, unsupervised, and reinforcement learning, and end up in a project on using unsupervised learning for implementing a simple portfolio trading strategy. About this Course 10,198 recent views The course aims at helping students to be able to solve practical ML-amenable problems that they may encounter in real life that include: (1) understanding where the problem one faces lands on a general landscape of available ML methods, (2) understanding which particular ML approach(es) would be most appropriate for resolving the problem, and (3) ability to successfully implement a solution, and assess its performance. A learner with some or no previous knowledge of Machine Learning (ML) will get to know main algorithms of Supervised and Unsupervised Learning, and Reinforcement Learning, and will be able to use ML open source Python packages to design, test, and implement ML algorithms in Finance. Fundamentals of Machine Learning in Finance will provide more at-depth view of supervised, unsupervised, and reinforcement learning, and end up in a project on using unsupervised learning for implementing a simple portfolio trading strategy. The course is designed for three categories of students: Practitioners working at financial institutions such as banks, asset management firms or hedge funds Individuals interested in applications of ML for personal day trading Current full-time students pursuing a degree in Finance, Statistics, Computer Science, Mathematics, Physics, Engineering or other related disciplines who want to learn about practical applications of ML in Finance Experience with Python (including numpy, pandas, and IPython/Jupyter notebooks), linear algebra, basic probability theory and basic calculus is necessary to complete assignments in this course.

In the example ETL pipeline below, three data files are transformed, loaded into a staging table, and finally aggregated into a final table. A common issue for ETL failures is missing data files for the latest day's run. If the data comes from an external source, check with the provider and confirm if the files are running late. If the data is internal such as application events or the company website activity, confirm with the team responsible if there were issues that could've caused delayed or missing data. Once you get the missing data your ETL issue is resolved.

This course introduces fundamentals concepts related to artificial intelligence (AI), and the services in Microsoft Azure that can be used to create AI solutions. The course is not designed to teach students to become professional data scientists or software developers, but rather to build awareness of common AI workloads and the ability to identify Azure services to support them. The course is designed as a blended learning experience that combines instructor-led training with online materials on the Microsoft Learn platform (https://azure.com/learn). The hands-on exercises in the course are based on Learn modules, and students are encouraged to use the content on Learn as reference materials to reinforce what they learn in the class and to explore topics in more depth. The Azure AI Fundamentals course is designed for anyone interested in learning about the types of solution artificial intelligence (AI) makes possible, and the services on Microsoft Azure that you can use to create them.
