A Gentle Introduction to Concept Drift in Machine Learning

Last Updated on August 12, 2019 Data can change over time. This can result in poor and degrading predictive performance in predictive models that assume a static relationship between input and output variables. This problem of the changing underlying relationships in the data is called concept drift in the field of machine learning. In this post, you will discover the problem of concept drift and ways to you may be able to address it in your own predictive modeling problems. […]

A Gentle Introduction to Transfer Learning for Deep Learning

Last Updated on September 16, 2019 Transfer learning is a machine learning method where a model developed for a task is reused as the starting point for a model on a second task. It is a popular approach in deep learning where pre-trained models are used as the starting point on computer vision and natural language processing tasks given the vast compute and time resources required to develop neural network models on these problems and from the huge jumps in […]

Why Applied Machine Learning Is Hard

How to Handle the Intractability of Applied Machine Learning. Applied machine learning is challenging. You must make many decisions where there is no known “right answer” for your specific problem, such as: What framing of the problem to use? What input and output data to use? What learning algorithm to use? What algorithm configuration to use? This is challenging for beginners that expect that you can calculate or be told what data to use or how to best configure an […]

A Gentle Introduction to Applied Machine Learning as a Search Problem

Last Updated on September 28, 2020 Applied machine learning is challenging because the designing of a perfect learning system for a given problem is intractable. There is no best training data or best algorithm for your problem, only the best that you can discover. The application of machine learning is best thought of as search problem for the best mapping of inputs to outputs given the knowledge and resources available to you for a given project. In this post, you […]

Caption Generation with the Inject and Merge Encoder-Decoder Models

Last Updated on August 7, 2019 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 of the recurrent neural network in addressing the problem. In this post, you will discover the inject and merge […]

A Gentle Introduction to Neural Machine Translation

Last Updated on August 7, 2019 One of the earliest goals for computers was the automatic translation of text from one language to another. Automatic or machine translation is perhaps one of the most challenging artificial intelligence tasks given the fluidity of human language. Classically, rule-based systems were used for this task, which were replaced in the 1990s with statistical methods. More recently, deep neural network models achieve state-of-the-art results in a field that is aptly named neural machine translation. […]
