A Standard Multivariate, Multi-Step, and Multi-Site Time Series Forecasting Problem

A Standard Multivariate, Multi-Step, and Multi-Site Time Series Forecasting Problem

Real-world time series forecasting is challenging for a whole host of reasons not limited to problem features such as having multiple input variables, the requirement to predict multiple time steps, and the need to perform the same type of prediction for multiple physical sites. In this post, you will discover a standardized yet complex time […]

How to Implement Beam Search Decoder for Natural Language Processing

How to Implement a Beam Search Decoder for Natural Language Processing

Natural language processing tasks, such as caption generation and machine translation, involve generating sequences of words. Models developed for these problems often operate by generating probability distributions across the vocabulary of output words and it is up to decoding algorithms to sample the probability distributions to generate the most likely sequences of words. In this […]

Caption Generation with the Inject and Merge Architectures for the Encoder-Decoder Model

Caption Generation with the Inject and Merge Encoder-Decoder Models

Caption generation is a challenging artificial intelligence problem that draws on both computer vision and natural language processing. The encoder-decoder recurrent neural network architecture has been shown to be effective at this problem. The implementation of this architecture can be distilled into inject and merge based models, and both make different assumptions about the role […]

A Gentle Introduction to Exploding Gradients in Recurrent Neural Networks

A Gentle Introduction to Exploding Gradients in Neural Networks

Exploding gradients are a problem where large error gradients accumulate and result in very large updates to neural network model weights during training. This has the effect of your model being unstable and unable to learn from your training data. In this post, you will discover the problem of exploding gradients with deep artificial neural […]
