Digitalization, Big Data and data collection is the keyword of many companies nowadays. Even museums digitize their artworks. A local museum from Bayreuth photographed 17786 posters showing invitations to exhibitions or advertising for specific events. Our department received this data to find patterns in it. More specifically, one shall order the posters in clusters to sort them logically. Furthermore, if there is a new poster, the clustering should present all posters with similar attributes. Since how to do it was relatively open, I tried four different methods to cluster the posters. First, I used a supervised approach with a neural network and another dataset from WikiArt to perform Transfer Learning. The following two approaches are based on the text printed on the posters. I extracted the text and first performed clustering with the BERT Topic Modeling approach, then with the LDA Topic Modeling approach. Lastly, I focused on the image by extracting the features with a pre-trained neural network and then performing PCA and K-Means to find a pre-defined number of clusters. The three unsupervised approaches produced some output that is workable but is not satisfactory enough.

The dependencies to this project are stored in the file:
- requirements.txt
I use python version 3.7.4
Go into the Code and then Scripts folder The two parameters:
- batch_size (recommended 32-256)
- epochs (recommended more than 50)
python training.py --batchsize 256 --epochs 100
The PyTorch Pipeline will start training based on:
- labels.csv
- train.csv
- test.csv
Train and Test have already been stratified in split in the correct way. Labels defines the 20 most common labels.
jupyter notebook
type this command into your console while being in the right folder, then you can open the jupyter notebooks inside the Notebooks folder.
Important: The .py files in the Scripts folder (e.g. easyocr.py) are designed for the webapp with Streamlit (app.py) and therefore cannot be used alone.

Thanks a lot to Vincent Christlein from the Pattern Recognition Lab for a really good supervising through all my project.
