Why Use Machine Learning

 Why use Machine Learning

  • Automation of Complex Tasks: ML can automate decision-making processes, handling tasks that are too complex for traditional rule-based systems.
  • Handling Large-Scale Data: ML algorithms can process and analyze vast amounts of data, uncovering patterns and insights that would be impossible to identify manually.
  • Improved Accuracy: In many cases, ML models can make predictions and decisions with greater accuracy than humans, especially when dealing with complex data.
  • Adaptability: ML models can adapt to new data, continuously improving their performance over time as they are exposed to more information.

Use Cases:

  • Healthcare: Disease prediction, personalized medicine, medical image analysis.
  • Finance: Fraud detection, algorithmic trading, credit scoring.
  • Retail: Customer segmentation, recommendation systems, demand forecasting.
  • Manufacturing: Predictive maintenance, quality control, supply chain optimization.
  • Transportation: Autonomous vehicles, route optimization, traffic prediction.

Where to Use Machine Learning?

Ideal Scenarios for ML:

  1. When You Have Large and Complex Datasets: ML thrives on data. If you have a large dataset with complex patterns, ML can help uncover insights.
  2. When Task Automation is Needed: Tasks that are repetitive and time-consuming can often be automated using ML.
  3. When Human Expertise is Insufficient: In cases where human intuition or expertise falls short, such as in analyzing high-dimensional data, ML models can provide more accurate results.
  4. When Predictions Need to be Continuously Updated: If your system requires predictions to be updated frequently based on new data, ML models are well-suited for this purpose.

Limitations and Delimitations of Machine Learning

Limitations:

  1. Data Dependency: ML models require large amounts of high-quality data. Poor or insufficient data can lead to inaccurate predictions.
  2. Interpretability: Many ML models, especially complex ones like deep neural networks, are often seen as "black boxes," making it difficult to understand how they make decisions.
  3. Overfitting: ML models can become too tailored to the training data, performing well on it but poorly on new, unseen data.
  4. Computationally Expensive: Training ML models, especially on large datasets or with complex algorithms, can be computationally intensive and require significant resources.
  5. Bias and Fairness: If the training data is biased, the ML model can learn and propagate that bias, leading to unfair or unethical outcomes.

Delimitations:

  • Task-Specific: ML models are designed to solve specific tasks and do not possess general intelligence. A model trained to recognize images cannot automatically be used to predict stock prices.
  • Maintenance: ML models require ongoing maintenance, including updates and retraining with new data to remain accurate and effective.
  • Ethical Concerns: The use of ML in areas like surveillance, hiring, and law enforcement raises ethical questions about privacy, fairness, and accountability.

A set of documents that need to be classified, use the Naive Bayesian Classifier

-
The Naive Bayes Classifier is a probabilistic machine learning model widely used for classification tasks, including document classification. Based on Bayes' Theorem, it assumes that the features (in this case, words or terms in the documents) are conditionally independent given the class label. Despite this "naive" assumption, it often performs well in practice, especially for text classification. Steps to Perform Document Classification Using Naive Bayes 1.  Prepare the Dataset Documents : Assume you have a set of documents, each labeled with a category (e.g., "Sports", "Politics", "Technology"). Preprocessing : Tokenize the text into words. Remove stop words (e.g., "the", "is", "and"). Perform stemming or lemmatization to reduce words to their base forms. Convert text into a numerical representation, such as a  bag-of-words  or  TF-IDF  vector. 2.  Split the Dataset Divide the dataset into a  training set  and...

  Understanding Keras Models: Your Neural Network Blueprint Think of a Keras model as the blueprint or architecture for building neural networks. Keras is designed to be simple and lets you create models quickly, while running on powerful engines like TensorFlow in the background. The Three Ways to Build a Keras Model 1. Sequential API: The Straightforward Stack What it is: The easiest way to build a model, like stacking Lego blocks in a single, straight line. Best for: Standard networks where data flows directly from one layer to the next with no fancy detours. Limitation: It's too rigid for complex designs that need multiple inputs, outputs, or layers that share connections. 2. Functional API: The Flexible Designer What it is: A more powerful approach that lets you create complex, branch-like architectures. Best for: Advanced designs with multiple inputs/outputs, skip connections (like shortcuts in the network), or layers that are shared. Example: Building sophisticated models li...
