Built an AI tool that cleans datasets, fills missing values, and predicts unknown fields [P]

Our take

Introducing an innovative AI tool designed to streamline your data analysis process. Built using Streamlit, this tool intelligently fills missing values with machine learning models, predicts unknown columns using existing data, and detects anomalies. Additionally, it highlights correlations and feature importance, providing valuable insights for informed decision-making. Users can easily download the updated datasets for further exploration. I invite feedback on the model approach, accuracy, and potential improvements to enhance its effectiveness. Explore the tool on GitHub and share your thoughts!

Built an AI tool that cleans datasets, fills missing values, and predicts unknown fields [P]

I built a Streamlit-based AI data analysis tool that:

• Fills missing values using ML models (not just mean/median)

• Predicts any missing column using n-1 inputs

• Detects anomalies

• Shows correlations and feature importance

• Lets you download the updated dataset (Attached images show the UI and before vs after CSV file with a sample CSV available on the GitHub page, as well as an image showing the achieved performance metrics)

I wanted to test how well it works on real-world incomplete datasets.

Would love feedback on:

- model approach

- accuracy issues

- any improvements I should make

I built a tool that lets you skip Excel formulas (would love your feedbacks)Hey everyone, If you work with Excel a lot, you probably spend way too much time figuring out formulas and structuring data before you can actually get insights. I’ve been building a web app called Neural Sheet to simplify that workflow. Instead of writing formulas manually, you can just upload your Excel file, describe what you want in plain language, and it generates the result for you. You can then download everything back as a normal Excel file with full control. It’s still early, but most core features are already there, and I’d really value honest feedback from people who actually use spreadsheets daily. You get 30 free edits to try it out. If you hit the limit and want more, just DM me and I’ll top you up. Would love to hear what works, what doesn’t, and what feels missing. submitted by /u/NeuralSheet [link] [comments]
