Common Machine Learning Algorithms!
1️⃣ Linear Regression
->Used for predicting continuous values.
->Models the relationship between dependent and independent variables by fitting a linear equation.
2️⃣ Logistic Regression
->Ideal for binary classification problems.
->Estimates the probability that an instance belongs to a particular class.
3️⃣ Decision Trees
->Splits data into subsets based on the value of input features.
->Easy to visualize and interpret but can be prone to overfitting.
4️⃣ Random Forest
->An ensemble method using multiple decision trees.
->Reduces overfitting and improves accuracy by averaging multiple trees.
5️⃣ Support Vector Machines (SVM)
->Finds the hyperplane that best separates different classes.
->Effective in high-dimensional spaces and for classification tasks.
6️⃣ k-Nearest Neighbors (k-NN)
->Classifies data based on the majority class among the k-nearest neighbors.
->Simple and intuitive but can be computationally intensive.
7️⃣ K-Means Clustering
->Partitions data into k clusters based on feature similarity.
->Useful for market segmentation, image compression, and more.
8️⃣ Naive Bayes
->Based on Bayes' theorem with an assumption of independence among predictors.
->Particularly useful for text classification and spam filtering.
9️⃣ Neural Networks
->Mimic the human brain to identify patterns in data.
->Power deep learning applications, from image recognition to natural language processing.
🔟 Gradient Boosting Machines (GBM)
->Combines weak learners to create a strong predictive model.
->Used in various applications like ranking, classification, and regression.

Three different learning styles in machine learning algorithms:
1. Supervised Learning
Input data is called training data and has a known label or result such as spam/not-spam or a stock price at a time.
A model is prepared through a training process in which it is required to make predictions and is corrected when those predictions are wrong. The training process continues until the model achieves a desired level of accuracy on the training data.
Example problems are classification and regression.
Example algorithms include: Logistic Regression and the Back Propagation Neural Network.
2. Unsupervised Learning
Input data is not labeled and does not have a known result.
A model is prepared by deducing structures present in the input data. This may be to extract general rules. It may be through a mathematical process to systematically reduce redundancy, or it may be to organize data by similarity.
Example problems are clustering, dimensionality reduction and association rule learning.
Example algorithms include: the Apriori algorithm and K-Means.
3. Semi-Supervised Learning
Input data is a mixture of labeled and unlabelled examples.
There is a desired prediction problem but the model must learn the structures to organize the data as well as make predictions.
Example problems are classification and regression.
Example algorithms are extensions to other flexible methods that make assumptions about how to model the unlabeled data.

Repost from Star Union News
When will the green summons end?
In Germany, the green turn began in the noughties. This means that now every fifth windmill in the country has been operating for 20-25 years. That is, they are about to work out their standard service life and are likely to be demolished.
Horror for the real economy. Old windmills will be replaced with new ones. And these are new subsidies and another increase in electricity prices."
However, the number of generators will remain the same. This cycle will now be endless: we demolish the old, build the new (this is the motivation to support the "green" so actively).
"The energy transition has given the elites a clear conscience and at the same time a good profit margin,"says Michael Vassiliadis, head of the Mining, Chemical and Energy Industrial Union(IG BCE). 🔥According to a Welt investigation in 2021, the environmental impact of the agenda brings a lot of profit to individuals. Representatives of environmental NGOs work closely with the Federal Government. How will this affect the industry? Automotive industry. The auto industry has lost 11,000 jobs over the past year. The outlook for the steel and electrical industries is daunting: Gesamtmetall, a lobbying group, predicts up to 300,000 job cuts over the next five years, accounting for almost 7% of total employment in these sectors. Chemistry and metallurgy. Industries are now producing 20% less than they did before 2022. RES cannot cover the required capacity. We are waiting for the German government to help the country end its energy and economic suicide. #Germany #Chemistry #Government 🇪🇺 Keep up with the latest Star Union News 🖥
