3 Core Artificial Intelligence Formulas - Precision and Recall

The following are three artificial intelligence formulas regarding precision and recall:  

Precision

Precision is the percentage of true positives regarding the returns of the artificial intelligence (AI).

Precision = True Positive / All Predictive Positives * 100

Recall

Recall is the fraction of positive cases which are correctly identified via artificial intelligence (AI).

Recall = True Positive / True Positive + False Negative

F1 Score

F1 score is the measure of balance between precision and recall of the artificial intelligence (AI).

F1 score = 2 * Precision * Recall / Precision + Recall

Artificial General Intelligence (AGI):

• Definition: A type of AI which can understand, learn, and apply knowledge across a range of tasks at a level comparable to human intelligence.
• Significance: Aims to exhibit broad cognitive abilities similar to humans

Machine Learning (ML):

• Definition: A subset of AI which involves training algorithms to learn from and make predictions or decisions based on data.
• Significance: Enables systems to improve their performance over time without being explicitly programmed.

Neural Networks:

• Definition: A series of algorithms which mimic the operations of a human brain to recognize patterns and solve complex problems.
• Significance: Utilized in various applications such as image and speech recognition.

Top 3 AI Deep Learning Aspects

The following are the top three deep learning aspects:

Neural Networks:

• Convolutional Neural Networks (CNNs): Utilized for image and video recognition, CNNs adaptively learn spatial hierarchies of features from input images.
• Recurrent Neural Networks (RNNs): Sequential data tasks such as language modeling and time series prediction. RNNs have loops which allow information to persist, making them effective for tasks where context is crucial.

Training Techniques:

• Supervised Learning: Involves training the model on a labeled dataset, meaning the input comes with the correct output.
• Unsupervised Learning: Model is trained on data without labeled responses.
