In the self-supervised learning area, we saw new methodologies coming out. It worked on the issue of sequential decision making by introducing several baseline RL agents. This method was used to train and evaluate RL agents with a specific commonsense knowledge about objects, their attributes, and affordances. It released the text-based gaming environment called TextWorld Commonsense (TWC) to work on the problem of infusing RL agents with commonsense knowledge. IBM, too, has been active in the reinforcement learning segment in 2021. Such a method will see usage in systems where large-scale training use cases are involved. It is built as an extension of PyTorch and can work in both supervised and unsupervised situations with compatibility options with multiple CPUs and GPUs. In order to simplify such a process, social media giant Facebook (now Meta) came out with “ SaLinA” just a month back. The implementation of sequential decision processes is crucial for those working in reinforcement learning. The learning pipeline was divided into three stages- training in simulation by using an off-the-shelf RL algorithm, training a new policy simulation with only realistic observations, and lastly, collecting data using this policy on real robots and bringing out an improved policy from this. The diversity of objects used and the number of empirical evaluations performed made this reinforcement learning-based project unique. Here, DeepMind used reinforcement learning to train a robotic arm to balance and stack objects of different shapes. It released RGB-stacking as a benchmark for vision-based robotic manipulation. They also help robots to learn new tasks more quickly.Ī leader in the reinforcement learning space, DeepMind gave us some unique innovations this year. While the first one is a multi-task RL system for automated data collection and multi-task RL training, the latter is a data collection mechanism to collect episodes of various tasks on real robots and demonstrates a successful application of multi-task RL. To work on this issue, Google came out with MT-Opt and Actionable Models.

But, even training for one task using offline reinforcement learning will take a massive amount of time and huge computational expenditure. Robotics Simplifiedįor robots to be useful to mankind, they need to perform a variety of tasks. Think of any big name in tech- be it Facebook, Google, DeepMind, Amazon, or Microsoft, they are all investing significant time, money and effort in bringing out innovations in RL. Understanding its importance, the last few years have seen an accelerated pace in understanding and improving RL.

It learns through trial and error like human beings. What makes reinforcement learning (RL) different from other kinds of algorithms is that it does not depend on historical data sets.
Its application is found in a diverse set of sectors like data processing, robotics, manufacturing, recommender systems, energy, and games, among others. One of the most exciting areas in machine learning right now is reinforcement learning.
