Serving Static Files in Python With Django, AWS S3 and WhiteNoise

Introduction Websites generally need additional files such as images, CSS, and JavaScript files that are necessary to render complete web pages in a browser. In small projects, we can work our way around by providing absolute paths to our resources or by writing inline CSS and JavaScript functions in the HTML files. This is not only against the best coding practices but it also gets tricky when we are handling bigger projects, especially with multiple applications. In Django, the files […]

Change Figure Size in Matplotlib

Introduction Matplotlib is one of the most widely used data visualization libraries in Python. Much of Matplotlib’s popularity comes from its customization options – you can tweak just about any element from its hierarchy of objects. In this tutorial, we’ll take a look at how to change a figure size in Matplotlib. Creating a Plot Let’s first create a simple plot in a figure: import matplotlib.pyplot as plt import numpy as np x = np.arange(0, 10, 0.1) y = np.sin(x) […]

Combined Algorithm Selection and Hyperparameter Optimization (CASH Optimization)

Machine learning model selection and configuration may be the biggest challenge in applied machine learning. Controlled experiments must be performed in order to discover what works best for a given classification or regression predictive modeling task. This can feel overwhelming given the large number of data preparation schemes, learning algorithms, and model hyperparameters that could be considered. The common approach is to use a shortcut, such as using a popular algorithm or testing a small number of algorithms with default […]

Issue #102 – Nearest Neighbour Machine Translation

08 Oct20 Issue #102 – Nearest Neighbour Machine Translation Author: Dr. Patrik Lambert, Senior Machine Translation Scientist @ Iconic Introduction Taking into account context information in neural MT is an active area of research, with applications in document-level translation, domain adaptation and multilingual neural MT. Today we take a look at a method which combines predictions from a neural MT model and from a nearest neighbour classifier, retrieved from similar contexts in a datastore of cached examples. This approach, called […]

Hyperparameter Optimization With Random Search and Grid Search

Last Updated on September 19, 2020 Machine learning models have hyperparameters that you must set in order to customize the model to your dataset. Often the general effects of hyperparameters on a model are known, but how to best set a hyperparameter and combinations of interacting hyperparameters for a given dataset is challenging. There are often general heuristics or rules of thumb for configuring hyperparameters. A better approach is to objectively search different values for model hyperparameters and choose a […]

Issue #101 – Leveraging Monolingual Data with Self-Supervision for Multilingual Neural Machine Translation

02 Oct20 Issue #101 – Leveraging Monolingual Data with Self-Supervision for Multilingual Neural Machine Translation Author: Dr. Chao-Hong Liu, Machine Translation Scientist @ Iconic Introduction Multilingual Neural Machine Translation (NMT), which enables zero-shot MT, is a significant development since the start of NMT. On the one hand, we have evidence that models trained with multiple languages can outperform those trained on a bilingual basis. On the other hand, multilingual NMT also enables us to train models of a language pair […]
