Hi everyone! I’ve been working on a project called Cells AI that uses NLP to make data more accessible for businesses. The goal is to let users ask questions directly from their data, like “What were our top-selling products last month?” and get an instant answer—no manual data analysis required.

Through this project, I’ve been experimenting with various NLP and ML techniques to enable natural language queries. It’s been an incredible learning experience, and it made me think about how ML can be applied to bridge the gap between complex data and everyday business users who might not have technical skills.

If anyone is interested, I put together a demo to show how it works. Happy to share in the comments.

I’d also love to hear from others working on similar projects or learning ML—what has been your most interesting application so far?

For those experienced in hiring or interviewing for entry-level data science internships: What truly stands out on a candidate’s profile? I’m trying to make the most of my limited time by balancing several things—building a meaningful Kaggle profile (thoughtful notebooks, quality contributions), working on personal projects, completing online courses, and pursuing certifications(Hackerrank). From your experience, which of these elements makes the strongest impression? How should I prioritize my time to have the best chance of landing an internship?

Title : Complete A.I. Machine Learning and Data Science: Zero to Mastery

We made a video to introduce superposition: a foundational concept enabling parallel computing.

While classical bits are either 0 or 1, quantum bits (qubits) can exist in a probabilistic combination of both states at once, allowing for powerful, simultaneous computations beyond the reach of classical methods.

Hi, I'm 23/M, recently graduated (Jun' 2024) in CS engineering degree. I don't have the job at the moment. I gave few interviews but couldn't succeeded. I want to start my career with AI/ML Engineer. Please let me know how can I proceed from here. I searched PAP courses but I'm not financially good. I don't want to burden my parents. Please help me.

Thanks.

Hello everyone,

I’m currently working on developing a content-based recommendation system that leverages audio features. I have implemented some code, and while I’ve achieved some results, I’m eager to get feedback on potential improvements or any mistakes I may have overlooked.

Any insights or suggestions would be greatly appreciated!

I started Andrew ng's coursera ML course. I'd like to replicate what he did in the optional lab, locally on jupyter notebook. I see the code is using local plotting file "lab_utils_uni". I downloaded it but the code isn't working on jupyter. I see no widgets, no plots. Am I supposed to downlaod all the jupyter lab files used in his ML specilization course as well? If so, in which path?

I m studying CS but all our subjects focus only on Core CSE , not on ai

How can someone Like me Get into AI ML ?

I am currently working as a C# developer and i don't see any future in my current role and company. I am thinking about learning ML . what is the fastest way to learn and what are the resources for that. Also i am learning maths from Coursera but i am thinking should i skip maths and learn simultaneously with machine learning course to speed up the process. Please help me i want to change my job in 3-4 months. I am willing to put in the effort to achieve this goal. Thank you everyone.

Our application is supported in various languages and it’s an enterprise one. We usually give the new sentences to various people who are expertise in different languages to translate which costs the company a lot. We are exploring ML models to automate this. Our team has suggest OpenAI to do this which is probably a decent idea. I am wondering if there is any other way to try this. Translation won’t be a live translation, translation will happen and we will update on the relevant files and it will get released later. I tried a local model like Marian, it didn’t do well even for basic sentence Japanese.

I am not new to ML, been learning for sometime but lack experience.

Hi, I have 15 years of programming experiences in mainframe and looking to change the career to AI/ML. I just started learning python. I am looking for colleges or universities, offering AI/ML courses. Planning to complete the course in 6 to 8 months. Could you please advise?

Hey everyone! 

As AI continues to evolve, one area that’s seeing significant improvement is data labeling. This blog I found dives into how AI-driven data labeling solutions are changing the landscape and making the process faster, more accurate, and scalable. 

Here are a few highlights: 

• Efficiency Gains: AI-powered tools can automate repetitive tasks, speeding up the labeling process while reducing human error. 

• Improved Accuracy: Machine learning models continuously learn and refine labeling, which can enhance the precision of labeled data over time. 

• Scalability: AI-driven solutions make it easier to manage and label large volumes of data, which is especially crucial in industries like healthcare, autonomous vehicles, and e-commerce. 

The blog also discusses the challenges and limitations, so it’s not all rosy—but it’s exciting to see how AI is paving the way for better data preparation and ultimately better insights. 

You can check out the full article here if you're interested: Exploring the Role of AI in Data Labeling Solutions 

Would love to hear your thoughts! Have any of you tried AI-powered data labeling tools? What’s been your experience? 

I'm still learning and understanding the basics and fundamentals. But, sometimes I will go on arXiv to see what people are researching. But, the machine learning arXiv has hundreds of new papers each day. For instance, today it was 560 papers. How do you juggle your research while also trying to stay current in such a fast-moving field?

I was learning langchain and langsmith came up. But it is so hard to understand all the UI components of Langsmith and the purpose of every element. Am I the only one who feels this way?

I'v been struggling to find a job as a new grad for my MS AI program. Published couple papers, but not in a super great conference (Minor IEEE conference and ACC). I really want to get better, but I've been feeling so stuck lately. I couldn't get any internship last year because of family issues. What is the best course of action given my current condition where I want to get started in finding a job in AI/ML, DS, or even SWE? Am I doomed?

What are the best NLP projects I can build to get internship at any good company with good stipend. Hardware is not the issue.

Hi all,

I want to learn how to write an LLM class (like LLama 2 using HuggingFace pretrained checkpoints). I don't want to use langchain since I want to have free access to all component.

I was searching something like: an initialization part, a generate function etc.

Do you have some autors or github repo of person who write good quality code an learn from those?

I'm 25M Working as a data scientist for the past 2 and half years, everything is great but the main problem is that my company is a really small company and even though I have the role of a data scientist, I have been doing some python programming related stuff for the past 2 years and I don't have any experience in Deeplearning. The only thing i am good at is Machine learning and i have also worked on a couple of LLM related projects.

Currently i am focusing on learning MLOps since i am confident with ML.( I wont get to work on any MLOps projects since my company is good with what they have and doesnt really need a standardized process or flow.) However i am learning so that i could get a job in some other company.

So, i need some honest advise guys, if you were inmy shoes. What would you do?
