Representation learning aims to map high-dimensional data to often dense, compact, and generalizable representations. These learned representations can transfer well to other tasks and have been the principal method to solve problems in which data annotations are hard or even impossible to get.

It is common to see educational material explaining linear regression using gradient descent. In this post, we will take on linear regression through the lens of linear algebra and solve it using the singular value decomposition (SVD).

Speech denoising is a long-standing problem. In this article, we use Convolutional Neural Networks (CNNs) to tackle this problem. Given a noisy input signal, we aim to build a statistical model that can extract the clean signal (the source) and return it to the user.

If you train deep learning models for a living, you might be tired of knowing one specific and important thing: fine-tuning deep pre-trained models requires a lot of regularization.

Time Series Forecasting is the use of statistical methods to predict future behavior based on a series of past data. Simply put, we can think of it as a bunch of values collected through time. In this post, we explore two decomposition methods: additive and multiplicative decomposition.

We can categorize ML models based on the way they classify data. There are two types: generative and discriminative methods. Let's dive deeper into one of the most popular discriminative models - Logistic Regression.

To deal with problems with 2 or more classes, most ML algorithms work the same way. Usually, they apply some kind of transformation to the input data. The goal is to project the data to a new space. Then, they try to classify the data points by finding a linear separation.

Lately, Generative Models are drawing a lot of attention. Much of that comes from Generative Adversarial Networks (GANs). Let's investigate some recent techniques for improving GAN training.

Putting Machine Learning (ML) models to production has been a recurrent topic. To address this concern, TensorFlow (TF) Serving is Google’s best bet for deploying ML models to production.

Deep Convolution Neural Networks (DCNNs) have achieved remarkable success in various Computer Vision applications. Like others, the task of semantic segmentation is not an exception to this trend.

DenseNets offer very scalable models that achieve very good accuracy and are easy to train. The key idea consists sharing feature maps within a block through direct connections between layers.

Supervised learning has been the center of most researching in deep learning in recent years. However, the necessity of creating models capable of learning from fewer or no labeled data is greater year by year.

GANs are a kind of generative model in which two differentiable functions are locked in a game. The generator tries to reproduce data that come from some probability distribution. The discriminator gets to decide if its input comes from the generator or from the true training set.
