Ai concepts explained

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.

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  🖥

Learn Data Science in 2024 𝟭. 𝗔𝗽𝗽𝗹𝘆 𝗣𝗮𝗿𝗲𝘁𝗼'𝘀 𝗟𝗮𝘄 𝘁𝗼 𝗟𝗲𝗮𝗿𝗻 𝗝𝘂𝘀𝘁 𝗘𝗻𝗼𝘂𝗴𝗵 📚 Pareto's Law states that "that 80% of consequences come from 20% of the causes". This law should serve as a guiding framework for the volume of content you need to know to be proficient in data science. Often rookies make the mistake of overspending their time learning algorithms that are rarely applied in production. Learning about advanced algorithms such as XLNet, Bayesian SVD++, and BiLSTMs, are cool to learn. But, in reality, you will rarely apply such algorithms in production (unless your job demands research and application of state-of-the-art algos). For most ML applications in production - especially in the MVP phase, simple algos like logistic regression, K-Means, random forest, and XGBoost provide the biggest bang for the buck because of their simplicity in training, interpretation and productionization. So, invest more time learning topics that provide immediate value now, not a year later. 𝟮. 𝗙𝗶𝗻𝗱 𝗮 𝗠𝗲𝗻𝘁𝗼𝗿 ⚡ There’s a Japanese proverb that says “Better than a thousand days of diligent study is one day with a great teacher.” This proverb directly applies to learning data science quickly. Mentors can teach you about how to build a model in production and how to manage stakeholders - stuff that you don’t often read about in courses and books. So, find a mentor who can teach you practical knowledge in data science. 𝟯. 𝗗𝗲𝗹𝗶𝗯𝗲𝗿𝗮𝘁𝗲 𝗣𝗿𝗮𝗰𝘁𝗶𝗰𝗲 ✍️ If you are serious about growing your excelling in data science, you have to put in the time to nurture your knowledge. This means that you need to spend less time watching mindless videos on TikTok and spend more time reading books and watching video lectures. Join @datasciencefree for more ENJOY LEARNING 👍👍

If you want to get a job as a machine learning engineer, don’t start by diving into the hottest libraries like PyTorch,TensorFlow, Langchain, etc. Yes, you might hear a lot about them or some other trending technology of the year...but guess what! Technologies evolve rapidly, especially in the age of AI, but core concepts are always seen as more valuable than expertise in any particular tool. Stop trying to perform a brain surgery without knowing anything about human anatomy. Instead, here are basic skills that will get you further than mastering any framework: 𝐌𝐚𝐭𝐡𝐞𝐦𝐚𝐭𝐢𝐜𝐬 𝐚𝐧𝐝 𝐒𝐭𝐚𝐭𝐢𝐬𝐭𝐢𝐜𝐬 - My first exposure to probability and statistics was in college, and it felt abstract at the time, but these concepts are the backbone of ML. You can start here: Khan Academy Statistics and Probability - https://www.khanacademy.org/math/statistics-probability 𝐋𝐢𝐧𝐞𝐚𝐫 𝐀𝐥𝐠𝐞𝐛𝐫𝐚 𝐚𝐧𝐝 𝐂𝐚𝐥𝐜𝐮𝐥𝐮𝐬 - Concepts like matrices, vectors, eigenvalues, and derivatives are fundamental to understanding how ml algorithms work. These are used in everything from simple regression to deep learning. 𝐏𝐫𝐨𝐠𝐫𝐚𝐦𝐦𝐢𝐧𝐠 - Should you learn Python, Rust, R, Julia, JavaScript, etc.? The best advice is to pick the language that is most frequently used for the type of work you want to do. I started with Python due to its simplicity and extensive library support, and it remains my go-to language for machine learning tasks. You can start here: Automate the Boring Stuff with Python - https://automatetheboringstuff.com/ 𝐀𝐥𝐠𝐨𝐫𝐢𝐭𝐡𝐦 𝐔𝐧𝐝𝐞𝐫𝐬𝐭𝐚𝐧𝐝𝐢𝐧𝐠 - Understand the fundamental algorithms before jumping to deep learning. This includes linear regression, decision trees, SVMs, and clustering algorithms. 𝐃𝐞𝐩𝐥𝐨𝐲𝐦𝐞𝐧𝐭 𝐚𝐧𝐝 𝐏𝐫𝐨𝐝𝐮𝐜𝐭𝐢𝐨𝐧: Knowing how to take a model from development to production is invaluable. This includes understanding APIs, model optimization, and monitoring. Tools like Docker and Flask are often used in this process. 𝐂𝐥𝐨𝐮𝐝 𝐂𝐨𝐦𝐩𝐮𝐭𝐢𝐧𝐠 𝐚𝐧𝐝 𝐁𝐢𝐠 𝐃𝐚𝐭𝐚: Familiarity with cloud platforms (AWS, Google Cloud, Azure) and big data tools (Spark) is increasingly important as datasets grow larger. These skills help you manage and process large-scale data efficiently. You can start here: Google Cloud Machine Learning - https://cloud.google.com/learn/training/machinelearning-ai I love frameworks and libraries, and they can make anyone's job easier. But the more solid your foundation, the easier it will be to pick up any new technologies and actually validate whether they solve your problems.

Can AI replace data scientist? AI can automate many tasks that data scientists perform, but it is unlikely to completely replace them in the foreseeable future. Rather than replacing data scientists, AI will enhance their capabilities by automating repetitive tasks, allowing them to focus on higher-level strategy, decision-making, and ethical considerations. What AI Can Automate in Data Science: Data Cleaning & Preparation – AI can automate data wrangling tasks like handling missing values and detecting anomalies. Feature Engineering – AI-driven tools can generate and select features automatically. Model Selection & Hyperparameter Tuning – Automated Machine Learning (AutoML) can choose models, tune hyperparameters, and even optimize architectures. Basic Data Visualization & Reporting – AI tools can generate dashboards and insights automatically. What AI Cannot Replace: Problem-Solving & Business Understanding – AI cannot define business problems, formulate hypotheses, or align analysis with strategic goals. Interpretability & Decision-Making – AI-generated models can be complex, but a human expert is needed to interpret results and make decisions. Innovation – AI lacks the ability identify new opportunities, or design novel experiments. Ethical Considerations & Bias Handling – AI can introduce biases, and data scientists are needed to ensure fairness and ethical use.
