Difficulty level: Beginner

Duration: 33:03

Speaker: : Krishna Shenoy

Course:

This lesson provides an introduction to the Decision Making course, specifically focusing on hidden states in neural systems.

Difficulty level: Beginner

Duration: 31:30

Speaker: : Sean Escola

Course:

This tutorial introduces the *Sequential Probability Ratio Test *between two hypotheses 𝐻𝐿 and 𝐻𝑅 by running simulations of a *Drift Diffusion Model (DDM)*. As independent and identically distributed (*i.i.d*) samples from the true data-generating distribution coming in, we accumulate our evidence linearly until a certain criterion is met before deciding which hypothesis to accept. Two types of stopping criterion/stopping rule will be implemented: after seeing a fixed amount of data, and after the likelihood ratio passes a pre-defined threshold. Due to the noisy nature of observations, there will be a *drifting* term governed by expected mean output and a *diffusion* term governed by observation noise.

Difficulty level: Beginner

Duration: 4:46

Speaker: : Yicheng Fei

Course:

This tutorial covers how to simulate a Hidden Markov Model (HMM) and observe how changing the transition probability and observation noise impacts what the samples look like. Then we'll look at how uncertainty increases as we make future predictions without evidence (from observations) and how to gain information from the observations.

Speaker: : Maurice Smith

Course:

In this tutorial, you will perform a *Sequential Probability Ratio Test* between two hypotheses *HL* and *HR* by running simulations of a *Drift Diffusion Model (DDM)*.

Difficulty level: Beginner

Speaker: : Zhengwei Wu

Course:

In this tutorial, you will implement a continuous control task: you will design control inputs for a linear dynamical system to reach a target state.

Difficulty level: Beginner

Duration: 10:02

Speaker: : Zhengwei Wu

Course:

This lecture covers the utility of action, including the vigor and neuroeconomics of movement and applications to foraging and the marginal value theorem.

Difficulty level: Beginner

Duration: 28:48

Speaker: : Reza Shadmehr

Course:

This lecture provides an introduction to a variety of topics in reinforcement learning.

Difficulty level: Beginner

Duration: 39:12

Speaker: : Doina Precup

Course:

This tutorial presents how to estimate state-value functions in a classical conditioning paradigm using Temporal Difference (TD) learning and examine TD-errors at the presentation of the conditioned and unconditioned stimulus (CS and US) under different CS-US contingencies. These exercises will provide you with an understanding of both how reward prediction errors (RPEs) behave in classical conditioning and what we should expect to see if dopamine represents a "canonical" model-free RPE.

Difficulty level: Beginner

Duration: 6:57

Speaker: : Eric DeWitt

Course:

In this tutorial, you will use 'bandits' to understand the fundamentals of how a policy interacts with the learning algorithm in reinforcement learning.

Difficulty level: Beginner

Duration: 6:55

Speaker: : Eric DeWitt

Course:

In this tutorial, you will learn how to act in the more realistic setting of sequential decisions, formalized by Markov Decision Processes (MDPs). In a sequential decision problem, the actions executed in one state not only may lead to immediate rewards (as in a bandit problem), but may also affect the states experienced next (unlike a bandit problem). Each individual action may therefore affect affect all future rewards. Thus, making decisions in this setting requires considering each action in terms of their expected **cumulative** future reward.

Difficulty level: Beginner

Duration: 11:16

Speaker: : Marcelo Mattar

Course:

In this tutorial, you will implement one of the simplest model-based reinforcement learning algorithms, Dyna-Q. You will understand what a world model is, how it can improve the agent's policy, and the situations in which model-based algorithms are more advantageous than their model-free counterparts.
