EU adaptation policy The EU strategy on adaptation to climate change aims at making Europe more climate-resilient. Taking a coherent approach by complementing the activities of States, it promotes adaptation action across the EU, ensuring that adaptation considerations are addressed in all EU policies (mainstreaming), promoting greater coordination, coherence and information-sharing.
26/02/2021 · Policy Adaptation. A naïve way to adapt a policy to new environments is by fine-tuning parameters using a reward signal. In real-world deployments, however, obtaining a reward signal often requires human feedback or careful engineering, neither of which are scalable solutions.
Adaptation Policy - an overview ScienceDirect Topics
As discussed in our introduction, policy adaptation can be defined in two ways: (a) adaptation by changing policy parameters to match situational demands (Lotlikar and Mohania, 2006) and (b) adaptation by checking non-conformance behavior against an alternative policy derived from the original policy (Lewis et al., 2010).
adaptation vary by sector and policy area. This section identifies the challenges and opportunities for adaptation in areas that are fundamental for the achievement of the SDGs: infrastructure, gender, health and agriculture. Action across these policy areas can be underpinned by coherent.

For autonomous driving, we may for example want our policy to be robust to changes in lighting, weather, and road conditions, as well as car models, nearby buildings, different city layouts, and so forth. It is therefore natural to ask: rather than learning a policy robust to all conceivable environmental changes, can we instead adapt a pre-trained policy to the new environment through interaction? Left : training in a fixed environment. Right : training with domain randomization. In real-world deployments, however, obtaining a reward signal often requires human feedback or careful engineering, neither of which are scalable solutions.
In recent work from our lab, we show that it is possible to adapt a pre-trained policy to unseen environments, without any reward signal or human supervision. A key insight is that, in the context of many deployments of RL, the fundamental goal of the task remains the same, even though there may be a mismatch in both visuals and underlying dynamics compared to the training environment, e.
When training a policy in simulation and deploying it in the real world sim2real , there are often differences in dynamics due to imperfections in the simulation, and visual inputs captured by a camera are likely to differ from renderings of the simulation.
Illustration of our framework for adaptation. Left : training before deployment. The RL objective is optimized together with a self-supervised objective.
Right : adaptation during deployment. We optimize only the self-supervised objective, using observations collected through interaction with the environment. We propose PAD , a general framework for adaptation of policies during deployment , by using self-supervision as a proxy for the absent reward signal.
During training, we optimize a self-supervised objective jointly together with the RL task, where the two tasks share part of a neural network. During deployment, we can no longer assume access to a reward signal and are unable to optimize the RL objective.
However, we can still continue to optimize the self-supervised objective using observations collected through interaction with the new environment. Assuming that gradients of the self-supervised objective are sufficiently correlated with those of the RL objective, any adaptation in the self-supervised task may also influence and correct errors in the perception and decision-making of the policy.
Because an inverse dynamics model connects observations directly to actions, the policy can be adjusted for disparities both in visuals and dynamics e. We demonstrate the effectiveness of self-supervised policy adaptation PAD by training policies for robotic manipulation tasks in simulation and adapting them to the real world during deployment on a physical robot, taking observations directly from an uncalibrated camera.
In the demonstration below, we consider a Soft Actor-Critic SAC agent trained with an Inverse Dynamics Model IDM , with and without the PAD adaptation mechanism. Transferring a policy from simulation to the real world.
PAD adapts to changes in both visuals and dynamics, and nearly recovers the original success rate of the simulated environment. Policy adaptation is especially effective when the test environment differs from the training environment in multiple ways, e. Because it is often difficult to formally specify the elements that vary between a simulation and the real world, policy adaptation may be a promising alternative to domain randomization techniques in such settings.
Together with PAD, we release DMControl Generalization Benchmark , a new benchmark for generalization in RL based on the DeepMind Control Suite , a popular benchmark for continuous control from images. In the DMControl Generalization Benchmark, agents are trained in a fixed environment and deployed in new environments with e. We consider an SAC agent trained with an IDM, with and without adaptation, and compare to CURL, a contrastive method discussed in a previous post. Millions of lives and the safety of communities around the world are already at stake.
The recent report from the IPCC warned a major worsening of climate impacts is coming a decade earlier than previously anticipated with unprecedented and irreversible changes. It highlighted that certain impacts, such as extreme heat spells, would double in scale over the next decade, demanding unprecedented acceleration and investment in adaptation and resilience to counteract the growing climate emergency. It has been exactly the framework we needed, if only it could be lived up to.
He said countries are ready for new ambition on adaptation, and they are ready for much scaled up financing for adaptation too. Ban Ki-moon noted that the Africa Adaptation Acceleration Program, created by GCA in partnership with the African Development Bank and backed by the African Union, serves as a template for the ambition and approach that needs to be scaled across all regions of the world.
President of the Democratic Republic of Congo and Chair of the African Union, Felix-Antoine Tshisekedi said at the peak of the corona pandemic, there was a collective political will, by all countries, to address the crisis. The event, jointly organised by the African Union, GCA and the African Development Bank, will catalyse the acceleration of action, financing and partnership necessary to achieve a transformative shift in adaptation on the ground in Africa.
During the closed-door Dialogue, the global leaders present confirmed the imperatives for COP Adaptation ambition must be fully aligned with science and the realities of the climate emergency and must be constantly raised year on year in a pathway that COP26 can establish.
Kristalina Georgieva, managing director of the International Monetary Fund, who chaired the meeting, spoke about how finance is integral to adaptation ambition. Amina Mohammed, deputy secretary-general of the United Nations said they need massively scaled-up investment in adaptation and resilience. Yet, only 21 per cent of climate finance is channelled to adaptation efforts. Putin set for fourth term with 74 per cent of vote: exit poll. Istanbul nightclub massacre kills
