Decision Tree Classifier from Scratch: Classifying Student's Knowledge Level

#artificialintelligence

In simple words, Decision Tree Classifier is a Supervised Machine learning algorithm which is used for supervised classification problems. Under the hood in decision tree, each node asks a True or False question about one of the features and moves left or right with respect to the decision. You can learn more about Decision Tree from here. We are going to use a Machine Learning algorithms to find the patterns on the historical data of the students and classify their knowledge level, and for that we are going to write our own simple Decision Tree Classifier from scratch by using Python Programming Language. Though i am going to explain everything along the way, it will not be a basic level explanation.


State of the Art Model Deployment

#artificialintelligence

The normal life cycle of a machine learning model includes several stages, see Figure 1. There are countless online courses and articles about preparing the data and building models but there is much less material about model deployment. Yet, it is precisely at this stage where all the hard work of data preparation and model building starts to pay off. This is where models are used to score (or get predictions for) new cases and extract the benefits. My intent here is to fill this gap, so that you will be fully prepared to deploy your model using time tested resources.



Beating the S&P500 Using Machine Learning

#artificialintelligence

A machine learning algorithm written in Python was designed to predict which companies from the S&P 1500 index are likely to beat the S&P 500 index on a monthly basis. To do so, a random forest regression based algorithm, taking as input the financial ratios of all the constituents of the S&P 1500, was implemented. We will therefore skip step 1 in this article. Those with access to the datasets through the required subscriptions can instead refer to the complete notebook hosted on the following Github project: SP1500StockPicker. The random forest method is based on multiple decision trees.


SAS Tutorial Python Integration with SAS Viya

#artificialintelligence

In this SAS How To Tutorial, Ari Zitin explores several examples of Python integration with SAS. There are many SAS Viya Cloud Analytic Services (CAS) that can be submitted from Python. In this Python integration demo, Ari focuses on predictive modeling. He shows how to connect to CAS, access in-memory data, bring data locally to use Pandas, and prepare data for predictive modeling. Ari then steps through how to build, score and assess a Decision Tree model.

Amazon Simple Storage Service (S3) is an object storage service that offers high availability and reliability, easy scaling, security, and performance. Many companies all around the world use Amazon S3 to store and protect their data. PostgreSQL is an open-source object-relational database system. In addition to many useful features, PostgreSQL is highly extensible, and this allows to organize work with the most complicated data workloads easily. In this article, we will show how to load data into Amazon S3 and PostgreSQL, then how to connect these sources to Dremio, and how to perform data curation.


What is Data Science?

#artificialintelligence

Data Science is considered as one of the most modern and fascinating jobs of our time. It can be funny and can give you satisfaction, but is it really as it's described? At the beginning of their career, Data Scientists think that Data Science is a wonderful, magical world full of algorithms, Python functions that performs every possible spell with a line of code and statistical models able to detect the most useful correlations among data that could make you an invincible superhero in your company. You start dreaming about your CEO congratulating with you and shaking your hand, you begin to see decision trees and clusters everywhere and, of course, the most terrifying neural network architectures your mind can dream. But since the very first day of your first Data Science project, you start to realize what reality is.


How to train Boosted Trees models in TensorFlow

#artificialintelligence

Tree ensemble methods such as gradient boosted decision trees and random forests are among the most popular and effective machine learning tools available when working with structured data. Tree ensemble methods are fast to train, work well without a lot of tuning, and do not require large datasets to train on. In TensorFlow, gradient boosted trees are available using the tf.estimator API, which also supports deep neural networks, wide-and-deep models, and more. For boosted trees, regression with pre-defined mean squared error loss (BoostedTreesRegressor) and classification with cross entropy loss (BoostedTreesClassifier) are supported.
