Neural Net + TensorFlow. Introducing Cloud Hosted Deep Learning Models. Introducing Cloud Hosted Deep Learning Models At Algorithmia, we believe in democratizing access to state-of-the-art algorithmic intelligence.

That’s why we’re introducing a solution for hosting and distributing trained deep learning models on Algorithmia using GPUs in the cloud. Rotate Images in Python Using a Horizon Detection Algorithm - Algorithmia. When we look at an image, it’s fairly easy to detect the horizon line.

For computers, this task is somewhat more difficult: they need to understand the basic structure of the image, locate edges which might indicate a horizon, and pare out the edges which do not matter. Fortunately, Algorithmia boils this all down to a single API call: just send your image to deep horizon, an algorithm for horizon detection, and it tells you where the horizon line is. Let’s see how we can use this tool, in combination with Pillow (a fork of the Python Image Library), to automatically recompose any image so it’s level. Step 1: Install the Algorithmia Client While this demo is written using our Python client, our services are equally easy to use in a variety of other programming languages, or even via cURL. Introduction to Color Scheme Extraction - Algorithmia. As an artist, inspiration can come from anywhere: a particular texture, a design, or even a color scheme.

Instead of spending hours painstakingly extracting the hex codes from all of the important sections of an image, what if there was a way to automatically extract the most important parts of an image? Color Scheme extraction is able to find the most relevant colors in seconds. Choosing the right estimator — scikit-learn 0.17 documentation. Bayesian Methods for Hackers. An intro to Bayesian methods and probabilistic programming from a computation/understanding-first, mathematics-second point of view.

Prologue The Bayesian method is the natural approach to inference, yet it is hidden from readers behind chapters of slow, mathematical analysis. The typical text on Bayesian inference involves two to three chapters on probability theory, then enters what Bayesian inference is. Unfortunately, due to mathematical intractability of most Bayesian models, the reader is only shown simple, artificial examples. This can leave the user with a so-what feeling about Bayesian inference. After some recent success of Bayesian methods in machine-learning competitions, I decided to investigate the subject again. Implementation of k-means Clustering - Edureka. In this blog, you will understand what is K-means clustering and how it can be implemented on the criminal data collected in various US states.

The data contains crimes committed like: assault, murder, and rape in arrests per 100,000 residents in each of the 50 US states in 1973. Along with analyzing the data you will also learn about: Reading and interpreting data. Mining Massive Datasets from Coursera. UT.7.01x: Foundations of Data Analysis from edX. *Note - This is an Archived course* In a world that’s full of data, we have many questions: How long do animals in a shelter have to wait until they are adopted?

Can we model the growth of internet usage in a country? Do films with a more adult rating make more money that other rated films? Luckily, the world is also full of data to help us answer those questions. This course will walk through the basics of statistical thinking – starting with an interesting question.

This course is designed for people who already know how to program. The course description makes it seem like the class is intended for everyone, even those who do not know how to program at all, which caused a lot of pain in the class forums. Computational Methods for Data Analysis from Coursera. DAT206x: Excel for Data Analysis and Visualization from edX.

Microsoft Excel is one of the most widely used solutions for analyzing and visualizing data.

Beginning with Excel 2010, new tools were introduced to enable the analysis of more data, resulting in less time spent creating and maintaining the solutions and enabling a better understanding of what the data means. This better understanding is facilitated by improved visualizations and more sophisticated business logics.

Do you want to take your advanced Excel skills to the next level? Excel for Data Analysis and Visualization. This is an Archived Course EdX keeps courses open for enrollment after they end to allow learners to explore content and continue learning. All features and materials may not be all available.

Exploratory Data Analysis from Coursera. The first 2 weeks of the course provide a thorough overview of plotting in R using the base graphical package, the lattice package and the ggplot2 package.

Week 3 takes a sudden detour into data clustering and the fairly advanced topics of principal components analysis and single value decomposition only jump back to plotting with a section on color. The clustering section seems a little about of place since there is not any introduction explaining the purpose of clustering. Getting Started With Processing. Processing is a language for visualization.

It started as a tool to bring designers into the world of coding, but ended up being super useful and attracting more attention. It’s free, easy to use, and can produce some beautiful visualizations. Also, it’s based in Java, so if you know Java, this will be intuitive. If not, it’s a great way to get your feet wet. If you find yourself becoming Processing obsessed, go to the source.

I have been a knowledge management consultant for more than 20 years, so I was drawn to it initially because I wanted to see how it would cover the subject. During the early weeks I re-visited much that I already knew, but as it progressed, it became progressively more interesting and exciting. For me the most valuable topic was Week 6, Big Data. From a wider perspective, if you want to understand the whole Knowledge Management enchilada, (knowledge and the techniques, tools and processes for its management), the Cloud and our Big Data future, there is no better place to start.
