General Directions for Using the Observation Forms The Parent-Individual Child Form Select a week period to observe your child in a wide range of routines, activities, and settings. Use the space provided to write notes about what you see your child doing in each domain as you observe throughout daily routines and activities. Observe the child in a variety of settings and activities, including meals, dressing, playtime with friends, and family and community activities.

Success depends on the mastery of several core visuo-motor skills: To make matters more complicated, these skills must be applied in the right sequence. Control tasks, like tidying up a table or stacking objects, require an agent to determine how, when and where to coordinate the nine joints of its simulated arms and fingers to move Observation children playing on playground and achieve its objective.

The sheer number of possible combinations of movements at any given time, along with the need to carry out a long sequence of correct actions constitute a serious exploration problem—making this a particularly interesting area for reinforcement learning research.

Techniques like reward shaping, apprenticeship learning or learning from demonstrations can help with the exploration problem. However, these methods rely on a considerable amount of knowledge about the task—the problem of learning complex control problems from scratch with minimal prior knowledge is still an open challenge.

SAC-X is based on the idea that to learn complex tasks from scratch, an agent has to learn to explore and master a set of basic skills first. Just as a baby must develop coordination and balance before she crawls or walks—providing an agent with internal auxiliary goals corresponding to simple skills increases the chance it can understand and perform more complicated tasks.

The auxiliary tasks we define follow a general principle: For example, activating a touch sensor in its fingers, sensing a force in its wrist, maximising a joint angle in its proprioceptive sensors or forcing a movement of an object in its visual camera sensors. Each task is associated with a simple reward of one if the goal is achieved, and zero otherwise.

This might be an auxiliary task or an externally defined target task. Crucially, the agent can detect and learn from reward signals for all other tasks that it is not currently following by making extensive use of replay-based off-policy learning.

Because a sequence of simple tasks can lead to the observation of a rare external reward, the ability to schedule intentions is crucial. It can create a personalised learning curriculum based on all the tangential knowledge it has collected.

This turns out to be an effective way to exploit knowledge in such a large domain, and is particularly useful when there are only few external reward signals available. Our agent decides which intention to follow via a scheduling module. The scheduler is improved during training via a meta-learning algorithm that attempts to maximise progress on the main task, which results in significantly improved data-efficiency.

Our evaluations show that SAC-X is able to solve all the tasks we set it from scratch—using the same underlying set of auxiliary tasks.

Excitingly, SAC-X is also able to successfully learn a pick-up and a placing task from scratch directly on a real robot arm in our lab.

In the past this has been particularly challenging because learning on robots in a real-world setup requires data-efficiency, so a popular approach is to pre-train an agent in simulation and then transfer the agent to the real robot arm.

We consider SAC-X as an important step towards learning control tasks from scratch, when only the overall goal is specified. SAC-X allows you to define auxiliary tasks arbitrarily: In that respect, SAC-X is a general RL method that is broadly applicable in general sparse reinforcement learning settings beyond control and robotics.

Read the paper here.As a part of routine health supervision by a primary health care provider, children should be evaluated for nutrition-related medical problems, such as failure to thrive, overweight, obesity, food allergy, reflux disease, and iron-deficiency anemia (1).

Published: Mon, 5 Dec Method of observation. The method of observation that I will be using is time sampling, the reason is that it allows me to point out many important information in an exact time and it is useful because it gives a wider picture of the child.

Playground Observations. September 10 I have witnessed adults without children sit down and watch kids playing and it gives me the creeps! I’m not trying to stereotype these individuals, but it seems rather bizarre. I know he is fast and doesn’t recognize danger.

On our last playground visit, there was a group of three women so. Additionally, no differences were observed between children with complete data (i.e. observation data at 3 time points) and partial data (1–2 time points) on these descriptive variables at .

Observation Children Playing On Playground. Introduction I observed three children of the age of 5 to 6 years old at the water play area in a private kindergarten. The indoor water play is located in the basement. Their names are Anna, Dean and Amy. The water play area had a huge container of water.
