This lecture is part of the Neuromatch Academy (NMA), a massive, interactive online summer school held in 2020 that provided participants with experiences spanning from hands-on modeling experience to meta-science interpretation skills across just about everything that could reasonably be included in the label "computational neuroscience".

This lecture on model types introduces the advantages of modeling, provide examples of different model types, and explain what modeling is all about. This lecture contains links to 3 tutorials, lecture/tutorial slides, suggested reading list, and 3 recorded question and answer sessions.

This tutorial covers Generalized Linear Models (GLMs), which are a fundamental framework for supervised learning. In this tutorial, the objective is to model a retinal ganglion cell spike train by fitting a temporal receptive field: first with a Linear-Gaussian GLM (also known as ordinary least-squares regression model) and then with a Poisson GLM (aka "Linear-Nonlinear-Poisson" model). This tutorial also covers a special case of GLMs, logistic regression, and learn how to ensure good model performance. This tutorial is designed to run with retinal ganglion cell spike train data from Uzzell & Chichilnisky 2004.

This tutorial covers multivariate data can be represented in different orthonormal bases.

Overview of this tutorial:

- Generate correlated multivariate data
- Define an arbitrary orthonormal basis

This tutorial covers how to perform principal component analysis (PCA) by projecting the data onto the eigenvectors of its covariance matrix.

Overview of this tutorial:

- Calculate the eigenvectors of the sample covariance matrix.
- Perform PCA by projecting data onto the eigenvectors of the covariance matrix.
- Plot and explore the eigenvalues.

To quickly refresh your knowledge of eigenvalues and eigenvectors, you can watch this short video (4 minutes) for a geometrical explanation. For a deeper understanding, this in-depth video (17 minutes) provides an excellent basis and is beautifully illustrated.

Course:

This tutorial covers how to apply principal component analysis (PCA) for dimensionality reduction, using a classic dataset that is often used to benchmark machine learning algorithms: MNIST. We'll also learn how to use PCA for reconstruction and denoising.

Overview of this tutorial:

- Perform PCA on MNIST
- Calculate the variance explained
- Reconstruct data with different numbers of PCs
- (Bonus) Examine denoising using PCA

You can learn more about MNIST dataset here.

Course:

This tutorial covers how dimensionality reduction can be useful for visualizing and inferring structure in your data. To do this, we will compare principal component analysis (PCA) with t-SNE, a nonlinear dimensionality reduction method.

Overview of the tutorial:

- Visualize MNIST in 2D using PCA
- Visualize MNIST in 2D using t-SNE

Neuromatch Academy aims to introduce traditional and emerging tools of computational neuroscience to trainees. It is appropriate for student population ranging from undergraduates to faculty in academic settings and also includes industry professionals. In addition to teaching the technical details of computational methods, Neuromatch Academy also provide a curriculum centered on modern neuroscience concepts taught by leading professors along with explicit instruction on how and why to apply models.

This lecture introduces the concept of Bayesian statistics and explains why Bayesian statistics are relevant to studying the brain.

Difficulty level: Beginner

Duration: 31:38

Speaker: : Paul Schrater

Course:

This tutorial provides an introduction to Bayesian statistics and covers developing a Bayesian model for localizing sounds based on audio and visual cues. This model will combine **prior** information about where sounds generally originate with sensory information about the **likelihood** that a specific sound came from a particular location. The resulting **posterior distribution** not only allows us to make optimal decision about the sound's origin, but also lets us quantify how uncertain that decision is. Bayesian techniques are therefore useful **normative models**: the behavior of human or animal subjects can be compared against these models to determine how efficiently they make use of information.

Overview of this tutorial

- Implement a Gaussian distribution
- Use Bayes' Theorem to find the posterior from a Gaussian-distributed prior and likelihood.
- Change the likelihood mean and variance and observe how posterior changes.
- Advanced (
*optional*): Observe what happens if the prior is a mixture of two gaussians?
