Meme Generator

This is an automated AI meme generator. On selecting a particular meme template a relating caption to that meme template gets generated. Here, the mechanism is similar to a captioning model but no images were used for training. This is a fun project I created to test the sarcasm levels of a trained model. The application has then been deployed on AWS.

Idea

I was tired of working on projects for industry level with use cases. Sometimes there are times when you need to take a step back and relax, when you need to look back on why you chose this particular field. This was a different idea. Although it might not be something that has a use case but it is definitely something that you can look at and chuckle with you friends. It was fun creating this project and sometimes you do need to work on silly projects as well.

Sample Results

Here is a clip of realtime clip of the working of the application.

Some Other Examples

Here are some other memes generated by AI. I have to give it to it's sense of humour.

Meme	My take
	Fair Point
	First World Problems
	Seems like I gave the model way too much data
	Oops, no comment
	No comments here as well
	I have no clue to it's reference
	Spittin' Facts
	Uff burn
	Third world country kid meme
	Relatable, hence making AI do so.

Dataset

This project used ImgFlip scraped dataset.

Setup

Clone the repository : git clone https://github.com/Shreyz-max/Memes-Generator.git

Video Caption Generator: cd Memes-Generator

Create environment: conda create -n meme_generator python=3.8

Activate environment: conda activate meme_generator

Install requirements: pip install -r requirements.txt

Usage

To use the models that have already been trained. Download the models from here and place them in models folder. Change the model_weights_path in config file.

Run python3 app.py

If you want to train from scratch, you can run the following scripts in the sequence.

First we will clone the dataset library. git clone https://github.com/schesa/ImgFlip575K_Dataset.git Here you can either scrape from scratch. The script for scraping from scratch is present in the repo itself. I used the already existing dataset. I used the individual json files in dataset folder. So the first step is to convert this into dataset for training.

Hence, run the code python3 preprocess.py

This is followed by python3 preprocess_captions.py

Now, for the training, run python3 train.py

Model

DistillGPT2 is finetuned to generate captions. In here, the way this model is trained is such that, for each meme template a token has been assigned. You can check out the tokens in special_tokens.py. Now, the inference works just like any other transormer model. Given the category token it has to predict the remaining words hence generating a caption. It also has two other tokens. One signifies the end of the sentence and other signifies the end of the box. End of the box tells us the upper and lower caption on the meme template. This generated text along with the category is passed to ImgFlip Api to generate the meme. I added a bit of front end to make it look a bit more interactive. This is then deployed to AWS. The link to try this by yourself is here .

Future Development

• Using other transformers more advanced transformers
• Working on a larger dataset
