## What is inverse reinforcement learning?

Inverse reinforcement learning (IRL) is the problem of inferring the reward function of an agent, given its policy or observed behavior. Analogous to RL, IRL is perceived both as a problem and as a class of methods.

**How does a Gaussian process work?**

In probability theory and statistics, a Gaussian process is a stochastic process (a collection of random variables indexed by time or space), such that every finite collection of those random variables has a multivariate normal distribution, i.e. every finite linear combination of them is normally distributed.

### What is Gaussian process classification?

The Gaussian Processes Classifier is a classification machine learning algorithm. Gaussian Processes are a generalization of the Gaussian probability distribution and can be used as the basis for sophisticated non-parametric machine learning algorithms for classification and regression.

**What is inverse optimal control?**

Inverse optimal control, also known as inverse reinforcement learning, is the problem of re- covering an unknown reward function in a Markov decision process from expert demon- strations of the optimal policy. This allows it to learn from exam- ples that are unsuitable for prior methods.

#### What is multi agent reinforcement learning?

Multi-agent reinforcement learning studies how multiple agents interact in a common environment. That is, when these agents interact with the environment and one another, can we observe them collaborate, coordinate, compete, or collectively learn to accomplish a particular task.

**When would you use a Gaussian process?**

Gaussian Process is a machine learning technique. You can use it to do regression, classification, among many other things. Being a Bayesian method, Gaussian Process makes predictions with uncertainty. For example, it will predict that tomorrow’s stock price is $100, with a standard deviation of $30.

## Why use a Gaussian process?

Gaussian processes are a powerful algorithm for both regression and classification. Their greatest practical advantage is that they can give a reliable estimate of their own uncertainty.

**What are the Hyperparameters of Gaussian process?**

The hyperparameters in Gaussian process regression (GPR) model with a specified kernel are often estimated from the data via the maximum marginal likelihood. Due to the non-convexity of marginal likelihood with respect to the hyperparameters, the optimization may not converge to the global maxima.

### Is linear regression a Gaussian process?

In the general case of linear regression, the ϵ term is just assumed to be a white noise, and therefore you cannot call it gaussian process regression.

**What is true about deep reinforcement learning?**

Deep reinforcement learning is a category of machine learning and artificial intelligence where intelligent machines can learn from their actions similar to the way humans learn from experience. Inherent in this type of machine learning is that an agent is rewarded or penalised based on their actions.

#### What is reinforcement machine learning?

Reinforcement learning is an area of Machine Learning. It is about taking suitable action to maximize reward in a particular situation. It is employed by various software and machines to find the best possible behavior or path it should take in a specific situation.

**What is Gaussian process regression used for?**

The Gaussian processes model is a probabilistic supervised machine learning frame- work that has been widely used for regression and classification tasks. A Gaus- sian processes regression (GPR) model can make predictions incorporating prior knowledge (kernels) and provide uncertainty measures over predictions [11].
