How jaydhandhukiya14/nyc_house_types-prediction works
Purpose and Entry Points
Listing-Forecast is a small NYC Airbnb listing prediction project. The runnable backend entry point is main.py; its prediction model is persisted at model/Model_Pipeline.pkl. A separate static browser interface starts from Frontend/index.html and loads client behavior from Frontend/script.js.
Model Training Artifact
The repository ships a prebuilt serialized model pipeline rather than training at runtime. model/Model_Pipeline.pkl is the core inference dependency, likely encapsulating preprocessing and the estimator. Training/exploration appears to be represented by notebook/nyc_airbnb_room_type.ipynb, backed by dataset/AB_NYC_2019.csv.
Backend Inference Layer
main.py is the application control boundary: it should receive listing attributes, load/use the model pipeline, run inference, and return a forecast or classification result. It is the integration point between request-facing behavior and the offline-generated model artifact.
Frontend Client Layer
The frontend is a standalone static UI:
• Frontend/index.html defines the page and input surface.
• Frontend/script.js collects user input and invokes prediction behavior.
• Frontend/style.css supplies presentation.
Its key boundary is communication with the backend in main.py; deployment must make their expected endpoint/origin available together or configure cross-origin access.
Data Flow
1. Historical Airbnb records originate in dataset/AB_NYC_2019.csv.
2. The notebook in notebook/nyc_airbnb_room_type.ipynb explores/trains the model workflow.
3. The trained pipeline is saved as model/Model_Pipeline.pkl.
4. main.py loads the pipeline and applies it to incoming listing data.
5. The frontend renders user inputs and displays the returned prediction.
Runtime and Dependencies
Python is the model-serving runtime, pinned/selected through .python-version and dependency definitions in requirements.txt. Browser execution requires only static HTML/CSS/JavaScript assets under Frontend/. The only identified external data source is the bundled NYC Airbnb CSV; no cloud infrastructure, database, or third-party API is represented in the supplied tree.
