You Should Know:

Text Analysis

  • Naive Bayes:
    from sklearn.naive_bayes import MultinomialNB
model = MultinomialNB()
model.fit(X_train, y_train)
  • BERT:
    from transformers import BertTokenizer, BertModel
tokenizer = BertTokenizer.from_pretrained('bert-base-uncased')
model = BertModel.from_pretrained('bert-base-uncased')

Multiclass Classification

  • Random Forest:
    from sklearn.ensemble import RandomForestClassifier
clf = RandomForestClassifier(n_estimators=100)
clf.fit(X_train, y_train)
  • XGBoost:
    import xgboost as xgb
model = xgb.XGBClassifier()
model.fit(X_train, y_train)

Anomaly Detection

  • Isolation Forest:
    from sklearn.ensemble import IsolationForest
clf = IsolationForest(contamination=0.1)
clf.fit(X_train)
  • DBSCAN:
    from sklearn.cluster import DBSCAN
clustering = DBSCAN(eps=0.5, min_samples=5).fit(X)

Image Classification

  • CNN (TensorFlow):
    from tensorflow.keras.models import Sequential
from tensorflow.keras.layers import Conv2D, MaxPooling2D, Flatten, Dense
model = Sequential([
Conv2D(32, (3,3), activation='relu', input_shape=(64, 64, 3)),
MaxPooling2D(2,2),
Flatten(),
Dense(128, activation='relu'),
Dense(10, activation='softmax')
])

Regression

  • Linear Regression:
    from sklearn.linear_model import LinearRegression
reg = LinearRegression().fit(X_train, y_train)
  • Lasso Regression:
    from sklearn.linear_model import Lasso
lasso = Lasso(alpha=0.1).fit(X_train, y_train)

Recommender Systems

  • Collaborative Filtering (Surprise Lib):
    from surprise import Dataset, KNNBasic
data = Dataset.load_builtin('ml-100k')
algo = KNNBasic()
algo.fit(data.build_full_trainset())

Clustering

  • K-Means:
    from sklearn.cluster import KMeans
kmeans = KMeans(n_clusters=3).fit(X)
  • Hierarchical Clustering:
    from scipy.cluster.hierarchy import dendrogram, linkage
Z = linkage(X, 'ward')
dendrogram(Z)

What Undercode Say

AI algorithms are the backbone of modern machine learning. Mastering these techniques requires hands-on practice with real-world datasets. Linux users can leverage tools like scikit-learn, TensorFlow, and `PyTorch` for efficient AI development.

Useful Linux Commands for AI Workflow:

 Install Python libraries 
pip install scikit-learn tensorflow torch

Monitor GPU usage (for deep learning) 
nvidia-smi

Run Jupyter Notebook 
jupyter notebook --ip=0.0.0.0 --port=8888

Process large datasets efficiently 
awk -F',' '{print $1}' dataset.csv > extracted_data.txt

Windows AI Development:

 Create a Python virtual environment 
python -m venv ai_env 
.\ai_env\Scripts\activate

Install CUDA for GPU acceleration (if applicable) 
choco install cuda

Expected Output:

  • A structured understanding of AI algorithms.
  • Ready-to-use code snippets for implementation.
  • Linux/Windows commands for AI workflow optimization.

Prediction

AI algorithm efficiency will continue improving with quantum computing integration, reducing training times significantly.
