R Memory^3 : Language Modeling with Explicit Memory

TL;DR who needs plain text knowledge database when you can use memory?

Paper: https://arxiv.org/pdf/2407.01178

Abstract:

>The training and inference of large language models (LLMs) are together a costly process that transports knowledge from raw data to meaningful computation. Inspired by the memory hierarchy of the human brain, we reduce this cost by equipping LLMs with explicit memory, a memory format cheaper than model parameters and text retrieval-augmented generation (RAG). Conceptually, with most of its knowledge externalized to explicit memories, the LLM can enjoy a smaller parameter size, training cost, and inference cost, all proportional to the amount of remaining "abstract knowledge". As a preliminary proof of concept, we train from scratch a 2.4B LLM, which achieves better performance than much larger LLMs as well as RAG models, and maintains higher decoding speed than RAG. The model is named Memory^(3), since explicit memory is the third form of memory in LLMs after implicit memory (model parameters) and working memory (context key-values). We introduce a memory circuitry theory to support the externalization of knowledge, and present novel techniques including a memory sparsification mechanism that makes storage tractable and a two-stage pretraining scheme that facilitates memory formation.

I've created a celebrity trivia game in Flask that uses information from their Wiki page as clues

I wrote this game a couple of years ago, and I've just ported it to a Flask app on my website.

Site: https://jimmyrustles.pythonanywhere.com/celebritytrivia

Github: https://github.com/sgriffin53/celebritytriviaapp

What My Project Does

It gives you clues from the celebrity's Wikipedia page, and you have to guess the celebrity.

Here's an example game:

(born June 22, 1973) is an American television host, radio personality, producer, and television personality.

Clue 1: had a small role on Dave Chappelle's show Chappelle's Show..

Clue 2: The Download with , syndicated (2013– ).

Clue 3: At the end of the summer of 1997, MTV hired as a permanent VJ, a position which required to relocate to New York.

Clue 4: In March 2000, Tara Reid met on the set of Total Request Live, and they began dating.

Clue 5: When social media correspondent Christina Milian departed the show in 2013, became the sole host.

The answer for this would be Jennifer Love Hewitt.

You can request as many clues as you like and it'll give you 5 random clues from the Wiki page with each request. There

Is there a way to auto update apache server webpage when changes to code are made?

Before when my files were stored on apache the website seemed to auto update but now that I've migrated to an application server like flask, it doesn't seem to do this. Someone had told me that the html code might not auto update since its static type or cached but the python code should.

Command mode on iPad browsers does not work

Hey, I have been trying to use JupyterLab remotely with my ipad. I have no trouble being able to connect to the host and display everything in safari. However, my issue comes when im editing a notebook. When im editing a cell and i go back to command mode (using esc key on keyboard) the commands do not work. Also, Im unable to go back to edit mode using the keyboard, i can only go back by clicking inside the cell (which is annoying because i have to reach out to the screen or to my mouse every time). I have tried JupyterNotebook, JupyterLab and different iPad browsers. I dont get this issue on PC browsers.

Is there any fix to this?

Why choose Django?

I am learning front-end web development and I think it is time to choose a back-end framework. I want to use Django, but others are recommending the MERN stack. What should I choose? I don't care about the difficulty level or other factors; I only care about job demand.

What's the best and most modern e-commerce framework for Django?

I'm looking to build a shop with Django, but not sure the best way to go. I'd rather not have to build it from scratch or go with something ghastly like Woocommerce, so I'm looking for a framework that's relatively quick to set up, is easy to customise and has a good range of features.

From what I've found already:

Saleor seems the most fully featured but it also looks very complex, perhaps more than one person can set up in a reasonable amount of time. Can't be bothered with GraphQL/React etc. for a fairly basic shop.
Longclaw seems interesting, especially as it integrates with Wagtail, but it looks unmaintained and doesn't work with recent Django versions.
Django Oscar seems well maintained but it's hard to gauge what it's like as the demo site is down and the showcase sites have either been replaced or are not reachable.
Satchless was archived a while back and Plata, Cartridge/Mezzanine and LFS haven't been updated in years.

What do you do for e-commerce? Are there other approaches I've missed?

How to create PDFs with formatting requirements & dynamic content?

Hello,

TLDR: How do I (or generally speaking) generate PDFs with a specific formatting requirement using dynamic content?

I am attempting to build a web app (using Flask) for a local non-profit who hosts judged shows throughout the year. Part of their process is to print out place cards to put next to each entry (with the corresponding information). These place cards are usually printed on a standard 8.5 x 11 piece of paper. However, the paper is pre-perforated so that it is easier to just rip them apart.

So, what I am attempting to do is to use an HTML to PDF conversion tool (pdfkit) to convert an HTML page that has been separated into quadrants into a PDF document. Which I then send the client as a download.

However, every time I try this the PDF just doesnt work. Specifically, it does not keep the quadrant formatting. Rather, the page shows the quadrants as rows at the top of the page.

My question is: How does one use Flask and corresponding libraries to generate these type of dynamic content PDFs? Or, more generally, how do web apps generate PDFs in the wild?


Here is the HTML &

Is pytorch faster than numpy on a single CPU?

A while ago I had benchmarked pytorch against numpy for fairly basic matrix operations (broadcast, multiplication, inversion). I didn't run the benchmark for a variety of sizes though. It seemed that pytorch was markedly faster than numpy, possibly it was using more than one core (the hardware had a dozen of cores). Is that a general rule even if constraining pytorch to a single core?

What's the best deployment for a Django startup business? AWS? Heroku?

Hi All,

I’m a front end developer and I’m pretty close to wrapping up a side hustle project which is a Django e-commerce application locally on my machine and I would like to deploy this onto either AWS or Heroku. 

What would you guys suggest would be the best recommendation? 

I was looking into: 

 - Lightsail which is $7 a month for an instance of Django 4.2.13. 

 - Elastic Beanstalk with a free tier RDS. That would be $15/month.

 - Heroku (I have William Vincent’s books on Django and that’s what he uses so I was thinking of doing the same.)

Currently, I have both an AWS and Heroku account. 

Also, I have a domain name purchased for my side project in AWS. 

I’ve been messing around with Elastic Beanstalk this week and successfully was able to get their sample application out so I can get used to AWS. 

Ideally I would like to have a total of 2 environments (Staging and Production).

I’m also thinking about if this application gets lots of traffic in the future what would be the best out of the two. 

Heroku seems more straight forward with someone that has limited experience doing devops and deployments, but I’m not sure. AWS seems like I can screw something

First python project

I have been studying python for about 1 to 2 weeks and I have been really enjoying the language, I just wanted to show off what I made as my first big program/project.

What My Project Does
Its a very basic investing game I made to attempt to teach an investing motto that I think is very important, time in the market beats timing the market. It is completely console based so to be honest its pretty boring and it takes too long to play, but I am proud of it.
Target Audience
No target audience, just a project I did
Comparison
I can't really give it any comparisons, I just made it based off of an idea i had
