Here you’ll find all articles that use machine learning, whether it’s classic machine learning such as random forests or logistic regression, or deep learning.
Machine learning is a generic term for the “artificial” generation of knowledge from experience. This means that an artificial system learns from examples by recognizing patterns and regularities. For this purpose, algorithms build a statistical model based on training data. Such a system can also assess unknown data and make own assumptions. There are two groups of machine learning algorithms: supervised learning and unsupervised learning. In supervised learning, the training process is based on prelabeled data. This means that the algorithm can compare its predictions to the correct answers. In this way, the algorithm learns from errors by adjusting the statistical model. In contrast, in unsupervised learning, the training data is unlabeled. Therefore, the algorithm does not know if its predictions are right or wrong and thus needs to come to own conclusions.
This tutorial develops a Twitter bot in Python that will generate automated trading signals. The bot will pull real-time price data on various cryptocurrencies (Bitcoin, Ethereum, Doge, etc.) from the crypto exchange Gate.io and analyze it using predefined rules. Whenever the bot detects a relevant price change, it automatically posts a tweet via Twitter. Simple … Read more

Regression models based on recurrent neural networks (RNN) can recognize patterns in time series data, making them an exciting technology for stock market forecasting. What distinguishes these RNNs from traditional neural networks is their architecture. It consists of multiple layers of long-term, short-term memory (LSTM). These LSTM layers allow the model to learn patterns in … Read more
Online shopping has become a part of our daily lives, and online stores are continually seeking to improve their sales. One way to achieve this is by using machine learning to predict customers’ purchase intentions. This innovative process can help businesses understand their customers’ behavior and tailor their marketing strategies accordingly. In this article, we … Read more
Evaluating performance is a crucial step in developing regression models. Because regression models return continuous outputs, such models allow for different gradations of right or wrong. Therefore, we measure the deviation between predictions and actual values in numerical terms. However, a universal metric to measure the performance of regression models does not exist. Instead, there … Read more
