Comparative analysis of deep learning architectures
May 17, 2023 pm 04:34 PM
The concept of deep learning originates from the research of artificial neural networks. A multi-layer perceptron containing multiple hidden layers is a deep learning structure. Deep learning combines low-level features to form more abstract high-level representations to represent categories or characteristics of data. It is able to discover distributed feature representations of data. Deep learning is a type of machine learning, and machine learning is the only way to achieve artificial intelligence. So, what are the differences between various deep learning system architectures? 1. Fully Connected Network (FCN) A fully connected network (FCN) consists of a series of fully connected layers, with every neuron in each layer connected to every neuron in another layer. Its main advantage is that it is "structure agnostic", i.e. no special assumptions about the input are required. Although this structural agnostic makes the complete
This 'mistake' is not really a mistake: start with four classic papers to understand what is 'wrong' with the Transformer architecture diagram
Jun 14, 2023 pm 01:43 PM
Some time ago, a tweet pointing out the inconsistency between the Transformer architecture diagram and the code in the Google Brain team's paper "AttentionIsAllYouNeed" triggered a lot of discussion. Some people think that Sebastian's discovery was an unintentional mistake, but it is also surprising. After all, considering the popularity of the Transformer paper, this inconsistency should have been mentioned a thousand times. Sebastian Raschka said in response to netizen comments that the "most original" code was indeed consistent with the architecture diagram, but the code version submitted in 2017 was modified, but the architecture diagram was not updated at the same time. This is also the root cause of "inconsistent" discussions.

Multi-path, multi-domain, all-inclusive! Google AI releases multi-domain learning general model MDL
May 28, 2023 pm 02:12 PM
Deep learning models for vision tasks (such as image classification) are usually trained end-to-end with data from a single visual domain (such as natural images or computer-generated images). Generally, an application that completes vision tasks for multiple domains needs to build multiple models for each separate domain and train them independently. Data is not shared between different domains. During inference, each model will handle a specific domain. input data. Even if they are oriented to different fields, some features of the early layers between these models are similar, so joint training of these models is more efficient. This reduces latency and power consumption, and reduces the memory cost of storing each model parameter. This approach is called multi-domain learning (MDL). In addition, MDL models can also outperform single
