Offline Meta-Reinforcement Learning for Industrial Insertion
Zhao, Tony Z., Luo, Jianlan, Sushkov, Oleg, Pevceviciute, Rugile, Heess, Nicolas, Scholz, Jon, Schaal, Stefan, Levine, Sergey
Reinforcement learning (RL) can in principle let robots automatically adapt to new tasks, but current RL methods require a large number of trials to accomplish this. In this paper, we tackle rapid adaptation to new tasks through the framework of meta-learning, which utilizes past tasks to learn to adapt with a specific focus on industrial insertion tasks. Fast adaptation is crucial because prohibitively large number of on-robot trials will potentially damage hardware pieces. Additionally, effective adaptation is also feasible in that experience among different insertion applications can be largely leveraged by each other. In this setting, we address two specific challenges when applying meta-learning. First, conventional meta-RL algorithms require lengthy online meta-training. We show that this can be replaced with appropriately chosen offline data, resulting in an offline meta-RL method that only requires demonstrations and trials from each of the prior tasks, without the need to run costly meta-RL procedures online. Second, meta-RL methods can fail to generalize to new tasks that are too different from those seen at meta-training time, which poses a particular challenge in industrial applications, where high success rates are critical. We address this by combining contextual meta-learning with direct online finetuning: if the new task is similar to those seen in the prior data, then the contextual meta-learner adapts immediately, and if it is too different, it gradually adapts through finetuning. We show that our approach is able to quickly adapt to a variety of different insertion tasks, with a success rate of 100% using only a fraction of the samples needed for learning the tasks from scratch.

Learn TensorFlow for Data Science, ML and AI
TensorFlow is a state-of-the-art, open-source framework that streamlines developing and executing advanced analytics applications. It is powerful and holds the potential for training a model for any system with the help of graphs. It is heavily used by data scientists, developers, and predictive modelers to automate processes, develop new systems and parallel processing applications, such as neural networks. We can train and run deep neural networks for things like image video recognition, word embeddings, handwritten digit classification, etc. One of the tremendous advantages of TensorFlow is its open-source community of data scientists, ml researchers and data engineers who contribute to its repository to make it faster and more effective to develop and train ML and Deep Learning models.

Understanding the Why of Data Science and Machine Learning Is More Useful than Knowing the How
A large number of corporations are moving toward the field of data science and machine learning. There are industries ranging from pharmaceuticals, retail, manufacturing, and automobile industries that are seeking ways to promote their products and services with the use of intelligent systems driven by artificial intelligence. To make things interesting, they are being used in the development of software for self-driving vehicles that are going to take the world by surprise in the next 2โ3 years. In light of this, it is important to learn the most important technologies and innovations taking place, especially in the field of automation. To learn these new technologies and tools, there are a massive number of online courses that teach the fundamentals along with practical use cases.
NeurIPS Competition Instructions and Guide: Causal Insights for Learning Paths in Education
Gong, Wenbo, Smith, Digory, Wang, Zichao, Barton, Craig, Woodhead, Simon, Pawlowski, Nick, Jennings, Joel, Zhang, Cheng
Causal machine learning is a field that focuses on using machine learning method to tackle causality problems. Despite the recent progress of this field, there are still many unresolved challenges including missing data, selection bias, unobserved confounders, etc., which are ubiquitous in the real world. Advances in any of the above areas can greatly reduce the gap between research and real world impact. In this competition, we focus on two fundamental challenges of causal machine learning in the context of education using time-series data. The first is to identify the causal relationships between different constructs, where a construct is defined as the smallest element of learning. The second challenge is to predict the impact of learning one construct on the ability to answer questions on other constructs. Addressing these challenges will not only impact the causal ML community but also enable optimisation of students' knowledge acquisition, which can be deployed in a real edtech solution impacting millions of students. Participants will run these tasks in an idealised environment with synthetic data and a real-world scenario with evaluation data collected from a series of A/B tests. We expect participants to develop novel machine learning methodologies for causal discover between different constructs and the impact estimation of learning one construct on other constructs, which should bring fundamental advances to causal ML.

Gradient Descent for Machine Learning - A Beginners Playbook
Gradient Descent is the most widely used optimization strategy in machine learning and deep learning. Whenever the question comes to train data models, gradient descent is joined with other algorithms and ease to implement and understand. There is a common understanding that whoever wants to work with the machine learning must understand the concepts in detail. This article will also try to curate the information available with us from different sources, as a result, you will learn the basics. This week, I have got a task in my MSc AI course on gradient descent. If you are new to this journal, Open Tech Talks is your weekly sandbox for technology insights, experimentation, and inspiration with the primary objective of learning and sharing.
Distributed Constraint-Coupled Optimization over Lossy Networks
Doostmohammadian, Mohammadreza, Khan, Usman A., Aghasi, Alireza, Charalambous, Themistoklis
This paper considers distributed resource allocation and sum-preserving constrained optimization over lossy networks, where the links are unreliable and subject to packet drops. We define the conditions to ensure convergence under packet drops and link removal by focusing on two main properties of our allocation algorithm: (i) The weight-stochastic condition in typical consensus schemes is reduced to balanced weights, with no need for readjusting the weights to satisfy stochasticity. (ii) The algorithm does not require all-time connectivity but instead uniform connectivity over some non-overlapping finite time intervals. First, we prove that our algorithm provides primal-feasible allocation at every iteration step and converges under the conditions (i)-(ii) and some other mild conditions on the nonlinear iterative dynamics. These nonlinearities address possible practical constraints in real applications due to, for example, saturation or quantization among others. Then, using (i)-(ii) and the notion of bond-percolation theory, we relate the packet drop rate and the network percolation threshold to the (finite) number of iterations ensuring uniform connectivity and, thus, convergence towards the optimum value.
