Doodling, or creating spontaneous drawings, has caught the eye of neural networks. We’ll look into doodling and see if neural networks can learn to recognize these doodles. This mix of art and tech shows the potential of neural networks in recognizing doodles.
Over time, doodling has grown from a simple hobby to a big deal. Games like Google’s “Quick, Draw!” and Icons8’s doodling game have drawn in millions, creating thousands of doodles1. This gives researchers and engineers a lot to study, like patterns and techniques, which neural networks can use.
Researchers have studied doodles, like those of elephants, to understand them better. They found that people often switch to right-brain mode when drawing elephants, making their drawings very accurate1. Elephants were copied more often than other animals, showing a special interest in their unique look.
Knowing about animals affects how people doodle. Animals like turtles, cats, dogs, and horses are often drawn based on what people think they know about them1. The more someone knows about an animal, the more likely they are to stick to certain drawing styles.
Feelings also show up in doodles, especially when drawing animals like pigs, cats, dogs, and horses in left-brain mode. These drawings have more emotional and sudden lines, showing a deep connection to these animals1. Horses were found to be particularly hard to draw, with many giving up easily, showing the challenge in capturing their true nature1.

Get ready for an exciting look at how art and AI come together.
Deep learning models have changed how we analyze doodle images. They help us understand and sort through the huge amounts of data in the Kaggle doodle dataset2. These models use convolutional neural networks (CNNs) to make image recognition and classification better and faster.
In the Kaggle doodle dataset, with over 1 billion drawings and 340 labels, deep learning models classify doodles very well. They use networks like MobileNet and ResNet to spot differences and find patterns in doodles2.
Deep learning models are great at handling lots of data and finding important features on their own. They can have hundreds of hidden layers, which lets them learn in a more complex way3. This helps them see the small details in doodles, making them better at classifying them.
Deep Learning Models and the Black Box Conundrum
Even though deep learning models work really well, they’re often seen as “black boxes” because they have so many parameters2. They learn complex things from the data but it’s hard to understand how they make their predictions.
But, researchers are working on making these models more transparent. They’re using methods like spatial fractal analysis and principal component analysis to understand what the models are doing2.
The Success and Limitations of Deep Learning Models in Doodle Recognition
Deep learning models are really good at putting doodles into different categories2. But, they’re not always easy to understand. Their complex design and many parameters make it hard to see why they make certain predictions.
Despite this, deep learning is leading to more research and better models. People are working to make these models easier to understand without losing their ability to process doodles well. Finding the right balance between understanding and performance is key in deep learning.
Problem Introduction
Artificial intelligence has made huge strides in many areas, including doodling recognition. Doodling means drawing simple sketches for fun or without thinking. These doodles can tell us a lot when analyzed with neural networks.
Quick, Draw! is a game by Google Creative Lab and Data Arts Team that shows how AI works. Players draw pictures and a smart model tries to guess what they drew. This game has created the biggest doodling dataset ever.
Creating models that can correctly label doodles is a big challenge. It’s not just about recognizing shapes. Neural networks, like the human brain, help us understand doodles better.

Data Cleaning
Working with big datasets in image recognition is key to getting the best results. It’s important to clean the data well to deal with RAM and GPU limits, and to make data processing faster. Let’s look at how to do this:
RAM Restrictions
Big datasets and limited memory mean we need special strategies. Shuffling and splitting the data into smaller parts helps manage it better. Using Numpy arrays for matrix operations also speeds things up8.
GPU Restrictions
Using GPUs to process big datasets quickly is crucial. To get past GPU limits, we can use NVIDIA CUDA-X AI for faster data processing. This boosts model training and inference, making the image recognition system work better9.
Data Processing Techniques
For image recognition to work well, we need to process the data right. Cleaning the dataset means doing several things, like:
Standardizing Images: There are different ways to make images the same size for neural networks. This makes sure the data fits the model9.
Data Augmentation: This makes the model more accurate and prevents it from getting too specific. It creates new images by changing them in different ways. This makes the dataset more varied, helping the model learn from more examples9.
Using these techniques and solving RAM and GPU issues improves data cleaning. This leads to better model performance and accuracy. By optimizing how we process data, image recognition systems can handle big datasets better89.
Predictive Modeling
We looked into different modeling techniques for our doodle recognition system. We used a simple Convolutional Neural Network (CNN)10. Choosing the right number of epochs and step sizes was key to get accurate and efficient results.
The simple CNN model had about 1.1 million parameters and hit an accuracy rate of 70%10. We also tried reducing the learning rate and saving model weights to boost our doodle recognition system’s performance. These steps led to great results.
We didn’t stop at the simple CNN model. We also tested ResNet and MobileNet to see what they could do. The MobileNet model was as accurate as the simple CNN but ran faster10.
To make our modeling efficient, we started training on a part of the full dataset10. This cut down the training time without hurting the model’s performance. Then, we made all strokes in the dataset the same size, from 0 to 1, to train the network better10.
Our model had Convolutional Layers, Recurrent Layers (LSTM), and Dense Layers. These layers worked together to make our system better and more accurate10. This design was crucial for our doodle recognition system’s success.
To test the model, we made the drawing points simpler, removed extra padding, and scaled the images for better predictions10. These steps helped our predictive modeling work well.
Our work led to a doodle recognition system that was very accurate. It could predict doodles with great precision, like a 1-player Pictionary game10. This shows how powerful Convolutional Neural Networks can be in recognizing doodles.
Our Journey with Sketch Recognition
We are a team of Pei-Hsin Ho, Gina Huh, Shayna Patel, Matt Viteri, Kai-Ju Yu, and Tianyi Zhang. We started an exciting journey into the world of sketch recognition.
The Google Quick, Draw! dataset was our starting point. It has over 50 million drawings in 340 categories. We dove deep into this treasure trove of art, learning a lot about human doodling.
We tried different classifier models to understand their strengths and weaknesses. We looked at classic methods and advanced models like the Multi-Layer Perceptron (MLP). This helped us grasp how to recognize and classify doodles.
We built a simple Convolutional Neural Network (CNN) model. It had nine layers, including convolutional and max-pooling layers. This model was our first step into deep learning for sketch recognition.
We trained our CNN on 16,200 samples and tested it on 1,800. This model became key to our exploration of sketch recognition.
We also looked at the MobileNet model, which is smaller and faster. It was trained on the same data as our CNN model. MobileNet showed us how to make models faster and more accurate.
With our training, we got better at predicting what sketches would be. We used cross-validation to check our models. Around epoch 8 or 9, we saw our models get better at recognizing sketches without overfitting.
Our work in sketch recognition opened up new ideas and challenges. We found research on Sketch-a-Net, a program that recognized sketches better than humans. It was 74.5% accurate, beating human levels.
Sketch-a-Net was especially good at recognizing certain things like “seagull.” It showed how AI can capture details that humans miss.
The team used a huge dataset of 31,000,000 sketches to train Sketch-a-Net. This helped it learn to recognize many different strokes. This dataset showed us the huge potential of sketch recognition.
Sketch-a-Net was different because it worked with sketches drawn stroke by stroke. This approach changed how we see sketch recognition.
The team tweaked each image to help Sketch-a-Net recognize sketches better. This creative process taught us about the power of image augmentation.
