AI Vocabulary: Essential Terms for Machine Learning and Data Science

Artificial Intelligence (AI) is transforming industries, and understanding its key concepts is crucial. Below are fundamental AI terms explained, along with practical implementations and commands to reinforce your knowledge.

⏩ Anomaly Detection

Identifies unusual data patterns, useful in fraud detection and cybersecurity.

You Should Know:

• Use Python’s `scikit-learn` for anomaly detection:

  from sklearn.ensemble import IsolationForest
  import numpy as np</li>
  </ul>
  
  data = np.random.randn(100, 2)  Sample data
  model = IsolationForest(contamination=0.1)
  anomalies = model.fit_predict(data)
  print(anomalies)  -1 indicates anomalies
  

  – Linux command to monitor system anomalies:

  sudo tail -f /var/log/syslog | grep -i "error|warning"
  

  ⏩ Machine Learning

  Algorithms that improve through data exposure, enabling automated decision-making.

  You Should Know:

  • Train a simple ML model using scikit-learn:

    from sklearn.datasets import load_iris
    from sklearn.tree import DecisionTreeClassifier</li>
    </ul>
    
    iris = load_iris()
    X, y = iris.data, iris.target
    model = DecisionTreeClassifier()
    model.fit(X, y)
    print(model.predict([[5.1, 3.5, 1.4, 0.2]]))  Predict class
    

    – Linux command to check CPU usage (ML workloads):

    top -o %CPU
    

    ⏩ Generative AI

    Creates new content like text, images, or audio.

    You Should Know:

    • Generate text using OpenAI’s GPT API (Python):

      import openai</li>
      </ul>
      
      response = openai.ChatCompletion.create(
      model="gpt-3.5-turbo",
      messages=[{"role": "user", "content": "Explain AI in 50 words."}]
      )
      print(response.choices[bash].message.content)
      

      – Linux command to install `transformers` for local AI models:

      pip install transformers torch
      

      ⏩ Explainable AI (XAI)

      Makes AI decisions interpretable.

      You Should Know:

      • Use `SHAP` to explain model predictions:

        import shap
        from sklearn.ensemble import RandomForestClassifier</li>
        </ul>
        
        model = RandomForestClassifier()
        model.fit(X, y)
        explainer = shap.TreeExplainer(model)
        shap_values = explainer.shap_values(X)
        shap.summary_plot(shap_values, X)
        

        ⏩ Data Mining

        Analyzes large datasets to extract insights.

        You Should Know:

        • SQL query for pattern extraction:

          SELECT user_id, COUNT() as transactions 
          FROM sales 
          GROUP BY user_id 
          HAVING COUNT() > 10;  Frequent buyers
          

        • Linux command for log analysis:

          grep "purchase" /var/log/app.log | awk '{print $1}' | sort | uniq -c
          

        ⏩ GANs (Generative Adversarial Networks)

        Creates synthetic data using two competing models.

        You Should Know:

        • Train a simple GAN with TensorFlow:

          from tensorflow.keras.layers import Dense, Flatten, Reshape
          from tensorflow.keras.models import Sequential</li>
          </ul>
          
          generator = Sequential([
          Dense(128, input_dim=100, activation='relu'),
          Dense(784, activation='sigmoid'),
          Reshape((28, 28))
          ])
          generator.summary()
          

          ⏩ Chatbots

          AI tools simulating human conversations.

          You Should Know:

          • Build a chatbot with NLTK:

            import nltk
            from nltk.chat.util import Chat, reflections</li>
            </ul>
            
            pairs = [[r"hi|hello", ["Hello! How can I help?"]]]
            chatbot = Chat(pairs, reflections)
            chatbot.converse()
            

            ⏩ NLP (Natural Language Processing)

            Enables machines to understand human language.

            You Should Know:

            • Tokenize text using spaCy:

              import spacy</li>
              </ul>
              
              nlp = spacy.load("en_core_web_sm")
              doc = nlp("AI is transforming industries.")
              print([token.text for token in doc])
              

              – Linux command to process text files:

              cat text.txt | tr ' ' '\n' | sort | uniq -c  Word frequency
