Dear all, we hope you all are doing well and that you enjoyed the long weekend.
Here's just a quick reminder that this coming Thursday (May 23) and next Thursday (May 30) we will use the time 215pm-4pm for project work and discussions only. These will be our last two sessions of organized activity this semester.
Don't hesitate to contact us and best wishes to you all,

Dear all, this is the last week of lectures and due to a Machine Learning workshop starting Tuesday (see https://sites.google.com/view/physmlworkshop24/program if you are interested) we decided to move Tuesday's lecture to Monday at 1015am-12pm.

Same place as before and for those who cannot attend in person, zoom is an option. And the last session will also be recorded.

We will also have lab on Thursday and throughout May for those interested. We will keep our labs at Thursdays.

On Monday the plan is to give a summary of what we have covered this semester. This year we have covered

We have covered

  1. Discriminative methods

       a. With a review of neural networks

       b. CNNs and RNNs

Dear all, welcome back to our second last session this semester. Note the following: the lecture this Tuesday is digital (zoom) only since I (Morten)  am in the US May 5-11 for a short research stay.

Furthermore, since our original time 1015am-12pm means 315am-5am in the night for me, I would like to ask if we can move the live zoom session to 1.15pm-3pm Oslo time. I hope this works, if not, you can always watch the recording which I will upload right afterwards.

The plan for this week is to wrap up our discussions of Generative models. The emphasis is on

  1. Finalizing discussion of Generative Adversarial Networks

  2. Mathematics of diffusion models and selected examples. 

Reading on diffusion models.

  1. A central paper is the one by Sohl-Dickstein et al, Deep Unsupervised Learning using Non-e...

Dear all, this week we continue our discussion of variational autoencoders (VAEs), their mathematics and programming implementations. We will discuss again possible paths for project 2, see for example https://github.com/CompPhysics/AdvancedMachineLearning/blob/main/doc/Projects/2024/Project2/pdf/Project2.pdf

Note that we have moved the deadline to June 7.  

Two excellent articles summarize VAEs and diffusion models and our lecture this coming Tuesday follows these articles. They are

Dear all, we hope you had an enjoyable Easter break and have been able to properly recharge your batteries. 

This week we will start with generative models and the aim is to give you an overview of

1) Generative models in general and mathematics of generative models

2)  Our first generative model, the restricted Boltzmann machine (a so-called energy model). 

Most of the material we will cover is described by chapter 16 of Goodfellow et al, seehttps://www.deeplearningbook.org/contents/graphical_models.html.   If we get time

we will also discuss chapters 18.1 and 182. If you are not familiar with Markov chains and Monte Carlo methods, we recommend reading chapter 17 of the same authors.  The lecture notes this week will be upgraded and wil...

Dear all, we hope you all had an enjoyable weekend. And welcome back to FYS5429. This is our last session before the Easter break. From April 2 and till the end of the semester our focus will be on generative models only.

The plans for this week are 

  • Finalize our discussion on Autoencoders (AEs) and Principal Component Analysis (PCA)
  • Implement Autoencoders with TensorFlow/Keras and PyTorch
  • Start discussion of generative models and possible paths for project 2 if we get time

 

The Reading recommendations  are

  • Goodfellow et al chapter 14 on AEs and chapter 16 for start generative models
  • Rashcka et al. Their chapter 17 contains a brief introduction only.

Dear all, welcome back to a new week! We obviously hope that you've passed a great weekend.

This week we will discuss autoencoders (AEs) and this will be our final topic before the Easter break. The motivation behind the discussion of AEs is that they will allow us to catch at least two birds with one stone;

1) link with the principal component analysis and dimensionality reduction methods in general

2) prepare the ground for generative models, which will be the main topic after the Easter break.

We will dedicate the lecture on this coming Tuesday (March 12) and March 19 to the analysis of AEs. 

The more detailed plans for this week are

  • Discussion of Autoencoders (AEs)
  • Links between Principal Component Analysis (PCA) and AE. The lecture material has a larger focus on the PCA, which is an important unsupervised method as well as an important dimensionali...

Dear all and welcome back to FYS5429. We hope you've had a great weekend.

Two important messages first. Since I (=Morten)  am  away in the US for a short research stay Feb 4-14, the lectures tomorrow (Tuesday Feb 6) and next Tuesday (Feb 13) will be via zoom only.  The plan this week is to wrap up ( I have been slow here) the discussion on the mathematics of neural networks and links with automatic differentiation.  We will discuss code examples as well. The jupyter-notebook at https://github.com/CompPhysics/AdvancedMachineLearning/blob/main/doc/pub/week4/ipynb/week4.ipynb contains most of the information.

There will be some minor code additions during the day today (note all code examples are yet ready).

The hope is to get started with the basics of CNNs as well and use more...

Dear all, we hope you've had a great weekend. Here are our plans for this week

Discussion of possible projects

Review of neural networks and automatic differentiation

Discussion of codes

Please do send to Morten (mhjensen@uio.no) by the end of Monday (January 29) whether you wish to present a tentative project description (1-3 slides, 5-10 mins presentations and discussions) during the first hour. 

As of now only two groups have responded that they would like to present their tentative projects.  We are planning to discuss various projects and in case you have not yet decided what you want to work on, this may be a good opportunity to get inspired and/or even join  a specific group.

Else, much of the material this week is similar to last week and we will discuss and review (for those of you who have written a neural network code) the basics of neural networks, with the back propag...
