I'm curious about how modern systems generate memes. What algorithms do they use to understand the context of an image and pair it with text to create a funny combination? Do they rely on machine learning, neural networks, or simple templates? How does the humor evaluation work, and what metrics are used to determine a meme's success? Share your experiences and thoughts, folks.
What is meme generation and how does the meme creation algorithm work?

I've been experimenting with meme generation by combining CLIP for image analysis and GPT-2 for caption generation—the model first identifies what's in the image, then crafts text that I filter based on my friends' reactions. My humor assessment is simple: how many likes and laughs the meme gets, though research uses more complex metrics like human rating scales and BLEU-like scores.
Meme generation is a task where a system has to come up with a text caption that matches the content of an image and delivers a comedic effect. In practice, most modern approaches combine three levels: (1) extracting visual context, (2) generating text options, and (3) evaluating "humor quality."
For image analysis, pre-trained convolutional networks (ResNet, EfficientNet) or Vision Transformers are commonly used to extract image embeddings. These embeddings are then fed into multimodal models like CLIP, where visual and textual representations are jointly trained. Based on the extracted context, captions are generated: simple templates work quickly (e.g., "When…," "This is me after…"), but more flexible solutions use GPT-2/3-like language models fine-tuned on real meme corpora. During fine-tuning, a special token indicating "meme style" is often added to help the model better capture the humorous tone.
Evaluating meme quality remains the most challenging part. Two main approaches are typically used: (a) a "funny/not funny" classifier trained on user like data (Reddit, Instagram), and (b) metrics like BLEU/ROUGE that compare generated memes to real ones, though these only indirectly reflect humor. Some research incorporates "engagement ratings" (number of shares, comments) as an objective function and uses reinforcement learning (RLHF), where the reward is the collective audience response.
In summary, modern meme generation typically relies on a combination of vision-language models, large language generators, and RL optimization based on user metrics. Simple templates are still relevant for quick prototypes, while more advanced solutions allow adapting the style to specific subcultures.
