| ## 1. Project Description |
|
|
| This project implements a **multimodal product classification system** for Best Buy products. The core objective is to categorize products using both their text descriptions and images. The system was trained on a dataset of **almost 50,000** items. |
|
|
| The entire system is deployed as a lightweight, web application using **Gradio**. The app allows users to: |
|
|
| - Use both text and an image for the most accurate prediction. |
| - Run predictions using only text or only an image to understand the contribution of each data modality. |
|
|
| This project showcases the power of combining different data types to build a more robust and intelligent classification system. |

| ## 2. Methodology & Key Features |
|
|
| - **Core Task:** Multimodal Product Classification on a Best Buy dataset. |
|
|
| - **Pipeline:** |
|
|
| - **Data:** A dataset of \~50,000 products, each with a text description and an image. |
| - **Feature Extraction:** Pre-trained models are used to convert raw text and image data into high-dimensional embedding vectors. |
| - **Classification:** A custom-trained **Multilayer Perceptron (MLP)** model performs the final classification based on the embeddings. |
|
|
| - **Key Features:** |
|
|
| - **Multimodal:** Combines text and image data for a more accurate prediction. |
| - **Single-Service Deployment:** The entire application runs as a single, deployable Gradio app. |
| - **Flexible Inputs:** The app supports multimodal, text-only, and image-only prediction modes. |
|
|
| ## 3. Technology Stack |
|
|
| This project was built using the following technologies: |
|
|
| **Deployment & Hosting:** |
|
|
| - [Gradio](https://gradio.app/) – interactive web app frontend. |
| - [Hugging Face Spaces](https://huggingface.co/docs/hub/spaces) – for cost-effective deployment. |
|
|
| **Modeling & Training:** |
|
|
| - [TensorFlow / Keras](https://www.tensorflow.org/) – used to train the final MLP classification model. |
| - [Sentence-Transformers](https://www.sbert.net/) – for generating text embeddings. |
| - [Hugging Face Transformers](https://huggingface.co/docs/transformers/index) – for the image feature extractor (`TFConvNextV2Model`). |
|
|
| **Development Tools:** |
|
|
| - [Ruff](https://github.com/charliermarsh/ruff) – Python linter and formatter. |
| - [uv](https://github.com/astral-sh/uv) – fast Python package installer and resolver. |
|
|
| ## 4. Model Details |
|
|
| The final classification is performed by a custom-trained **Multilayer Perceptron (MLP)** model that takes the extracted embeddings as input. |
|
|
| - **Text Embedding Model:** `SentenceTransformer` (`all-MiniLM-L6-v2`) |
| - **Image Embedding Model:** `TFConvNextV2Model` (`convnextv2-tiny-22k-224`) |
| - **Classifier:** A custom MLP model trained on top of the embeddings. |
| - **Classes:** The model classifies products into a set of specific Best Buy product categories. |

| | Random Forest | Combined | 0.89 | 0.79 | 0.89 | |
| | Logistic Regression | Combined | 0.89 | 0.83 | 0.89 | |
| | **MLP** | **Image** | **0.84** | **0.77** | **0.84** | |
| | **MLP** | **Text** | **0.92** | **0.87** | **0.92** | |
| | **MLP** | **Combined** | **0.92** | **0.85** | **0.92** | |
|
|
| > [!TIP] |
| > |
| > Based on the evaluation on the test set, the Multimodal MLP model achieved an excellent **92% accuracy** and a **92% weighted F1-score**, confirming its superior performance by leveraging both text and image data. |
