The research sheds new light on how sex determines the mechanisms by which various synapses monitor and regulate dopamine signaling.A study in mice reveals a surprising difference between male and female dopamine synapses supporting attention, movement, motivation, and pleasure.Almost all neuropsychiatric disorders have different prevalences, ages of onset, and clinical symptoms in men and women. Attention-Deficit/Hyperactivity Disorder (<span class="glossaryLink" aria-describedby="tt"…

Presenting data patterns to models the right wayPhoto by Acton Crawford on UnsplashIntroductionThis post explains the three crucial processes in feature engineering (FE) that you need to know to properly present data patterns to machine learning (ML) models.Feature engineering is the process of modifying existing features to enhance the ability of a model to learn from the data.FE offers tangible improvement in model accuracy without significantly increasing computational time and cost.FE is a subset of data…

Having the infrastructure right for implementing MLOps solutionsIn my previous post, I have discussed the three key components to build an end-to-end MLOps solution, which are data and feature engineering pipelines, ML model training, and retraining pipeline ML model serving pipelines. You can find the article here : Learn the core of MLOPS — Building ML Pipelines. At the end of my last post, I briefly talked about the fact that the complexities of MLOps solutions can vary significantly from one to another, depending on…

Understanding The Characteristics of a Pandas SeriesPhoto by freestocks on UnsplashA Pandas Series is a one-dimensional array that can have a labeled, i.e., not a numerical, index. A series can also be thought of as a column in a table that can store data of various types.The basic installation of Python already brings four different data structures in which any data type can be stored:The list is an ordered collection of elements. It is changeable and able to store duplicate elements as well.The tuple is very similar to…

Caltech researchers developed a framework to design new materials that mimic the fundamental rules hidden in nature’s growth patterns. Credit: CaltechInspired by the way termites build their nests, scientists at the California Institute of Technology (Caltech) developed a framework to design new materials that mimic the fundamental rules hidden in nature’s growth patterns. The researchers demonstrated that by using these rules, it is possible to create materials designed with specific programmable properties.The research…

Fagradalsfjall volcano in Iceland erupting at night.Recent discoveries from Iceland’s Fagradalsfjall eruptions alter what we know about how volcanoes work.Learning something that fundamentally changes how we understand our world doesn’t happen very often. But for University of California, Santa Barbara Earth scientist Matthew Jackson and the thousands of volcanologists across the globe, such a revelation has just occurred.While sampling magma from the Fagradalsfjall volcano in Iceland, Jackson and his colleagues uncovered…

That will hopefully Make You Less confused about the Confusion MatrixPhoto by Daniele Levis Pelusi on UnsplashA confusion matrix is a tool for assessing the quality of a classification model in machine learning. It checks how many of the predictions were correctly or incorrectly assigned to a class.In the simplest case, a classification consists of two states. Suppose we want to investigate how well Corona tests reflect the infection status of a patient. In this case, the Corona test serves as a classifier of a total of…

From counts, lengths, and term frequencies to why you don’t need word cloudsImage by the author.Exploratory Data Analysis (EDA) is an important step in the workflow of any Data Science project. However, when working with text data in a Natural Language Processing (NLP) project, you need to apply different techniques than when working with e.g. tabular data.When working with text data you need to apply different techniques than when working with e.g. tabular data.Therefore, we will look at some fundamental EDA techniques…

The emission from M87 has now been resolved into a bright, thin ring (orange colormap), arising from the infinite sequence of additional images of the emission region, and the more diffuse primary image, produced by the photons that come directly toward Earth (in blue contours). When viewed at the imaging resolution of the Event Horizon Telescope, the two components blur together. However, by separately searching for the thin ring, it is possible to sharpen the view of M87, isolating the fingerprint of strong gravity.…

Brands and SEO professionals must take responsibility for the performance of the websites that they run and manage. Applying these six SEO truths will help you achieve next-level website performance, according to Bruce Clay, the founder and president of digital marketing optimization firm Bruce Clay Inc., who spoke at SMX Advanced. 1. SEO needs to be a strategic initiative across the company The entire organization participates in SEO. It starts at the leadership level –…
