📝 Introduction

The ‘Patches Are All You Need’ paper introduces the ConvMixer architecture, an innovative approach that has outperformed traditional CNN and Transformer based architectures. In this video, we will explore the architecture and its implementation in PyTorch.

🏞️ Architecture Overview

The ConvMixer architecture leverages patch embedding and con mixer layers to learn a powerful image representation. This approach involves dividing the input image into non-overlapping patches and applying a convolutional kernel to each patch. The resulting representations are then passed through the con mixer layers and a global average pooling operator, preparing them for classification.

🛠️ Patch Embedding and Con Mixer Layer

In the patch embedding layer, the input image is divided into non-overlapping patches, and each patch is embedded using convolutional kernels and a nonlinear activation function. This process aims to map each patch to an embedding vector, allowing for the extraction of essential image features.

In the con mixer layer, the extracted embeddings are further processed by applying the con mixer layers. This architecture utilizes local mixing of different tokens through convolutional operations, providing an efficient and effective approach for image representation learning.

🔗 Model Implementation in PyTorch

The model implementation in PyTorch involves defining the patch embedding layer, nonlinear activation functions, batch normalization, con mixer layers, global average pooling, and the classification head. These components collectively form the ConvMixer architecture, which can then be instantiated and trained using appropriate loss functions and optimizers.

🧪 Training and Evaluation

In the training process, the model is trained for a specified number of epochs, with the performance evaluated on both the train and test sets. The accuracy of the ConvMixer model on the test set is observed to be around 71%, indicating its effectiveness in image classification tasks.
