The processing of natural language is getting more and more popular. NLP is a field of artificial intelligence designed to understand and extract important information from text. The main areas that include the use of NLP are recognizing and generating voice, text analysis, sentiment analysis, automatic translation, etc.

There are various tools and libraries designed to resolve NLP problems. In this post we will look at some:

  1. Spacy is the prime competitor of NLTK. These…

Looking into the object.

Hello everyone! Today we will look at the parameters for AutoML for Scikit Learn and what each one means. This article could help you with deciding what to tune whenever you’re using Auto ML for Scikit Learn.

Vanilla auto-sklearn

In order to obtain vanilla auto-sklearn as used in Efficient and Robust Automated Machine Learning set ensemble_size=1 and initial_configurations_via_metalearning=0:

>>> import autosklearn.classification
>>> automl = autosklearn.classification.AutoSklearnClassifier(
>>> ensemble_size=1, initial_configurations_via_metalearning=0)

An ensemble of size one will result in always choosing the current best model according to its performance on the validation set. …


Using Auto ML from Scikit Learn

Hello again! Today I want to show you how to classify using Auto ML from Scikit Learn. For this example, I will be using the clean version of the titanic dataset. You are able to use the normal dataset as well, all I have done to it is remove the Nan values as well as converting to boolean values and removing any strings.

Before we start, you can check out my previous blog on how to install the package. …

Algorithms Grouped by Learning Style

There are different ways an algorithm can model a problem based on its interaction with the experience or environment or whatever we want to call the input data.

It is popular in machine learning and artificial intelligence textbooks to first consider the learning styles that an algorithm can adopt.

There are only a few main learning styles or learning models that an algorithm can have and we’ll go through them here with a few examples of algorithms and problem types that they suit.

This taxonomy or way of organizing machine learning algorithms is useful because it forces you to think…

MIT researchers have developed a new artificial intelligence programming language that can assess the fairness of algorithms more exactly, and more quickly, than available alternatives.

The justice system, banks, and private companies use algorithms to make decisions that have profound impacts on people’s lives. Unfortunately, those algorithms are sometimes biased — disproportionately impacting people of color as well as individuals in lower income classes when they apply for loans or jobs, or even when courts decide what bail should be set while a person awaits trial.

Their Sum-Product Probabilistic Language (SPPL) is a probabilistic programming system. Probabilistic programming is an…


How it works

During training, Auto Machine Learning creates a number of pipelines in parallel that try different algorithms and parameters for you. The service iterates through ML algorithms paired with feature selections, where each iteration produces a model with a training score. The higher the score, the better the model is considered to “fit” your data. It will stop once it hits the exit criteria defined in the experiment.

Using Auto Machine Learning, you can design and run your automated ML training experiments with these steps:

  1. Choose whether…


The tryout

Hello and welcome back! Today we’ll see an example of AutoML and what it can do. I will be using Auto-Sklearn as an example and might explore others in the future.

Today we will start with installing Auto-Sklearn and I will explain some errors I came across and how I troubleshoot them. I am using Jupyter Notebook for all of this as well as pip and homebrew.

Firstly I started by installing auto-sklearn by using pip.

$ pip install auto-sklearn

This should work according to the auto-sklearn documentation. Unfortunately, that was not the case for me. …


The implementations

There are many implementations of AutoML that you can try. Some are paid services, and some are free source code. The lists below are by no means complete or final.

AutoML services

All of the big three cloud services have some kind of AutoML. Amazon SageMaker does hyperparameter tuning but doesn’t automatically try multiple models or perform feature engineering. Azure Machine Learninghas both AutoML, which sweeps through features and algorithms, and hyperparameter tuning, which you typically run on the best algorithm chosen by AutoML. …

Welcome back! Now that we looked at what AutoML is in the previous blog, let’s dive a little into it. Today we’ll look at some great AutoML tools and libraries that are useful and that you might be interested in.

The future of Machine Learning?

IMG src: techgrabyte.com

So, as we know, machine learning is one of the most complex parts of Data Science. But what if there was a more time efficient way, or a more simpler way to do models, or maybe an automatic way? Well, today we’ll explore what Auto ML is.

What is it?

Automated machine learning (AutoML) is the process of automating the tasks of applying machine learning to real-world problems. AutoML covers the complete pipeline from the raw dataset to the deployable machine learning model. …
