How to piss off a Data Scientist in just 7 seconds: ☑ Peek at an AB experiment early, and insist that we can ship the feature now. ☑ Discard their analyses because it doesn’t agree with your gut feeling. ☑ Ask for data to support a conclusion that you’ve already made. ☑ Request an AI solution because “leadership wants one”. ☑ Argue that Data Science isn’t the sexiest career. ☑ Insist that they’re not real scientists.

Here are some essential machine learning algorithms that every data scientist should know: * Linear Regression: This is a supervised learning algorithm that is used for continuous target variables. It finds a linear relationship between a dependent variable (y) and one or more independent variables (X). It's widely used for tasks like predicting house prices or stock prices. * Logistic Regression: This is another supervised learning algorithm that is used for binary classification problems. It predicts the probability of an event happening based on independent variables. It's commonly used for tasks like spam email detection or credit card fraud detection. * Decision Tree: This is a supervised learning algorithm that uses a tree-like model to classify data. It breaks down a decision into a series of smaller and simpler decisions. Decision trees are easily interpretable, making them a good choice for understanding how a model makes predictions. * Support Vector Machine (SVM): This is a supervised learning algorithm that can be used for both classification and regression tasks. It finds a hyperplane that best separates the data points into different categories. SVMs are known for their good performance on high-dimensional data. * K-Nearest Neighbors (KNN): This is a supervised learning algorithm that classifies data points based on the labels of their nearest neighbors. The number of neighbors (k) is a parameter that can be tuned to improve the performance of the algorithm. KNN is a simple and easy-to-understand algorithm, but it can be computationally expensive for large datasets. * Random Forest: This is a supervised learning algorithm that is an ensemble of decision trees. Random forests are often more accurate and robust than single decision trees. They are also less prone to overfitting. * Naive Bayes: This is a supervised learning algorithm that is based on Bayes' theorem. It assumes that the features are independent of each other, which is often not the case in real-world data. However, Naive Bayes can be a good choice for tasks where the features are indeed independent or when the computational cost is a major concern. * K-Means Clustering: This is an unsupervised learning algorithm that is used to group data points into k clusters. The k clusters are chosen to minimize the within-cluster sum of squares (WCSS). K-means clustering is a simple and efficient algorithm, but it is sensitive to the initialization of the cluster centers.

Here are some essential AI terms that every data scientist should know: * Machine Learning (ML): A subfield of AI that allows computers to learn without being explicitly programmed. ML algorithms learn from data to make predictions or decisions. * Deep Learning (DL): A type of machine learning that uses artificial neural networks to model complex data. Deep learning models are inspired by the structure and function of the human brain. * Natural Language Processing (NLP): A subfield of AI that deals with the interaction between computers and human language. NLP tasks include machine translation, sentiment analysis, and speech recognition. * Computer Vision (CV): A subfield of AI that deals with the extraction of information from images and videos. CV tasks include object detection, image classification, and facial recognition. * Big Data: Large and complex datasets that are difficult to store, process, and analyze using traditional methods. Big data often includes data from multiple sources and in various formats. * Artificial Neural Network (ANN): A computational model inspired by the structure and function of the human brain. ANNs consist of interconnected nodes called neurons that can process information and learn from data. * Algorithm: A set of instructions that a computer can follow to perform a specific task. In AI, algorithms are used to train machine learning models and to make predictions or decisions. * Bias: A systematic preference for or against a particular outcome. Bias can be present in data, algorithms, and models. It's important to be aware of bias and to take steps to mitigate it. * Explainability: The ability to understand how a machine learning model makes decisions. Explainable models are more trustworthy and easier to debug. * Ethics: The branch of philosophy that deals with what is right and wrong. AI ethics is concerned with the development and use of AI in a responsible and ethical manner. Best Data Science & Machine Learning Resources: https://topmate.io/coding/914624 ENJOY LEARNING 👍👍
