Interpreting Coefficients in Linear Regression Models

Linear regression models are foundational in machine learning. Merely fitting a straight line and reading the coefficient tells a lot. But how do we extract and interpret the coefficients from these models to understand their impact on predicted outcomes? This post will demonstrate how one can interpret coefficients by exploring various scenarios. We’ll delve into …

Types of Chatbots: An Overview for Business People

In the effort to automate as many processes as possible, companies resort to various solutions powered by modern technology. We’ve written about Enterprise Resource Planning systems and automated contact centers lately. Internet bots, or simply bots, may be the best-known form of automation in customer communications. Gartner once predicted that by 2020, more than 50% …

On the Benefits of Pixel-Based Hierarchical Policies for Task Generalization

Reinforcement learning practitioners often avoid hierarchical policies, especially in image-based observation spaces. Typically, the single-task performance improvement over flat-policy counterparts does not justify the additional complexity associated with implementing a hierarchy. However, by introducing multiple decision-making levels, hierarchical policies can compose lower-level policies to more effectively generalize between tasks, highlighting the need for multi-task evaluations. …

Hydrogels can play Pong by ‘remembering’ previous patterns of electrical simulation

Non-living hydrogels can play the video game Pong and improve their gameplay with more experience, researchers report. The researchers hooked hydrogels up to a virtual game environment and then applied a feedback loop between the hydrogel’s paddle — encoded by the distribution of charged particles within the hydrogel — and the ball’s position — encoded …
