These are giant NLP models that are usually trained for text generation. https://kasraprime.com/blog/blogposts/paper-localizing-active-objects-from-egocentric-vision/ Thu, 08 Feb 2024 00:00:00 +0000 https://kasraprime.com/blog/blogposts/paper-localizing-active-objects-from-egocentric-vision/ This paper is published in ACL and you can find it using this link. It’s super interesting to see how different research projects are taking advantage of LLMs (GPT) by prompting them to do something and use those results to solve another problem. Summary This paper tackles the problem of grounding (localizing) objects in images using text instructions by focusing on pre- and post-conditions of target objects; they call this active object grounding. https://kasraprime.com/blog/blogposts/semi-live-journal/ Thu, 01 Feb 2024 00:00:00 +0000 https://kasraprime.com/blog/blogposts/semi-live-journal/ This is going to be a live page about all sorts of things that I find beautiful. I intend to update this post at least once a month. For more regular updates check out my telegram channel: Darvishak Let’s get down to business. Yet another text-to-video model <2024-02-01 Thu> LUMIERE is a new text-to-video model by Google Research. Lumiere uses a space-time diffusion model for video generation https://kasraprime.com/blog/blogposts/research-workflow/ Tue, 08 Aug 2023 16:12:23 -0400 https://kasraprime.com/blog/blogposts/research-workflow/ In order to be good at something, you need to have good tools. You need to hone your crafts. Research is no excemption either. The following is a talk I gave at IRAL Lab at UMBC https://kasraprime.com/blog/blogposts/machine-learning-experiment-tracking-with-wandb/ Tue, 08 Aug 2023 16:08:48 -0400 https://kasraprime.com/blog/blogposts/machine-learning-experiment-tracking-with-wandb/ https://kasraprime.com/blog/blogposts/research-skills/ Tue, 08 Aug 2023 15:58:51 -0400 https://kasraprime.com/blog/blogposts/research-skills/ Two of most important reserach skills that are usually not thought are networking and using AI tools. I presented the follwoing talk for the IRAL lab at UMBC. https://kasraprime.com/blog/blogposts/art/ Tue, 08 Aug 2023 00:00:00 +0000 https://kasraprime.com/blog/blogposts/art/ https://kasraprime.com/blog/blogposts/artificial-intelligence/ Tue, 08 Aug 2023 00:00:00 +0000 https://kasraprime.com/blog/blogposts/artificial-intelligence/ A branch of computer science which tries to create Intelligence in machines. https://kasraprime.com/blog/blogposts/chatgpt/ Tue, 08 Aug 2023 00:00:00 +0000 https://kasraprime.com/blog/blogposts/chatgpt/ An Artificial Intelligence chatbot and Nlp model by openAI. https://kasraprime.com/blog/blogposts/classification/ Tue, 08 Aug 2023 00:00:00 +0000 https://kasraprime.com/blog/blogposts/classification/ Why Classification As Gendler states (2011), “classifying objects into groups allows us to proceed effectively in an environment teeming with overwhelming detail.” Random Baseline In order to compute the accuracy of a random baseline for a multi-class classfication you can simply: \[acc = P(y=0) \times P(\hat{y}=0) + P(class is 1) \times P(you guess 1) \] where P(y=1) means the probability that the class is actually 1, and \(P(\hat{y}=1)\) means tne probability that you guess 1. https://kasraprime.com/blog/blogposts/generative-models/ Tue, 08 Aug 2023 00:00:00 +0000 https://kasraprime.com/blog/blogposts/generative-models/ Generative AI models are a broad area in Machine Learning that instead of Classification focus on creating data. Classification is about prediction which is really cool; Nostradamus ;) However, the ability to create is superior; We become Gods, new kind of gods that really exist! Also, if you can create, you can predict. With that introduction, we can jump into the edge of research in this field. This field is growing really fast and has gained a lot of attention from the public and media recently, especially the famous ChatGpt model by OpenAI. https://kasraprime.com/blog/blogposts/god/ Tue, 08 Aug 2023 00:00:00 +0000 https://kasraprime.com/blog/blogposts/god/ https://kasraprime.com/blog/blogposts/intelligence/ Tue, 08 Aug 2023 00:00:00 +0000 https://kasraprime.com/blog/blogposts/intelligence/ It’s hard to define intelligence. I will do it later! https://kasraprime.com/blog/blogposts/machine-learning/ Tue, 08 Aug 2023 00:00:00 +0000 https://kasraprime.com/blog/blogposts/machine-learning/ Teaching Whenever you want to explain machine learning to someone, use the example of Teaching. Machine learning is like taking an exam from students. You compare students’ results (model’s prediction) with the answers (labels) you have.

We have formal languages like programming languages, and natural languages like English. Natural languages are not formally specified, therefore we need statistical models to learn from examples, and approximate the natural lang. the number of times a term occurs in a document is called its term frequency Language modeling is the task of assigning a probability to sentences in a language. The notion of a language model is inherently probabilistic. https://kasraprime.com/blog/blogposts/teaching/ Tue, 08 Aug 2023 00:00:00 +0000 https://kasraprime.com/blog/blogposts/teaching/ Teaching is an Art to me. https://kasraprime.com/blog/blogposts/text-to-video-ai-models/ Fri, 07 Oct 2022 15:13:35 -0400 https://kasraprime.com/blog/blogposts/text-to-video-ai-models/ There has been great hype in multimodal research these past few days because of the release of multiple text-to-video models while text-to-image models are still pretty hype and not perfect yet. Diffusion models such as GLIDE in general and stable diffusion in particular are the state-of-the-art models for text-to-image tasks as of now. However, multiple papers came out recently that tackle the task of generating videos from text prompts or still images. https://kasraprime.com/blog/blogposts/regex/ Sun, 12 Dec 2021 00:00:00 +0000 https://kasraprime.com/blog/blogposts/regex/ Basics Use this website interactively to learn.

Don’t get me wrong, I still write everyday, but for myself, and it’s been a long time that I have not written anything publicly. Well, that’s about to change since I have some ideas to write about frequently. The theme of my frequent writings are the followings: Research Paper Summaries Journals and Diary Book Summaries and Recommendations Research Paper Summaries The papers are going to be mostly in Machine Learning and Artificial Intelligence, but I might write about other fields occasionally; these other areas could be Neuroscience, Cognitive Science, and more. https://kasraprime.com/blog/blogposts/note-taking/ Tue, 10 Aug 2021 00:00:00 +0000 https://kasraprime.com/blog/blogposts/note-taking/ Hey You Perfectionist Don’t spend endless hours contemplating the tools. Follow this rule: As long as you have access to your data and they are palin text, you will be fine. The worst is that you can’t convert your files easily to another plain text format, but even in that case you can search your files and find the data you are looking for. Don’t think about publishing and making it look good, because notes evolve over time and you don’t want the pdfs of them you created two years ago. https://kasraprime.com/blog/blogposts/blogging/ Wed, 03 Mar 2021 23:39:40 -0400 https://kasraprime.com/blog/blogposts/blogging/ Tools Jekyll Edit files in BuildBlog folder.

I am assuming that you are an undergrad or Master’s student and want to apply for Master’s or Ph.D. degree. Before starting to apply for universities, you need to have a reasonable resume, which means you have to learn different skills and have some research experiences in your field of study. https://kasraprime.com/blog/blogposts/editors-war/ Mon, 01 Jan 0001 00:00:00 +0000 https://kasraprime.com/blog/blogposts/editors-war/ https://kasraprime.com/blog/blogposts/obsidian/ Mon, 01 Jan 0001 00:00:00 +0000 https://kasraprime.com/blog/blogposts/obsidian/ https://kasraprime.com/blog/blogposts/second-brain-zettlekasten/ Mon, 01 Jan 0001 00:00:00 +0000 https://kasraprime.com/blog/blogposts/second-brain-zettlekasten/ https://kasraprime.com/blog/blogposts/vim/ Mon, 01 Jan 0001 00:00:00 +0000 https://kasraprime.com/blog/blogposts/vim/ https://kasraprime.com/blog/blogposts/vscode/ Mon, 01 Jan 0001 00:00:00 +0000 https://kasraprime.com/blog/blogposts/vscode/ https://kasraprime.com/blog/blogposts/channelb/ Mon, 01 Jan 0001 00:00:00 +0000 https://kasraprime.com/blog/blogposts/channelb/ Type: #podcast Scientist and the Sea (Episode 60) status: #DONE The story of Tommy Gregory Thompson a scientist who turns to a thief.
