SESSION 11 - Machine learning for enterprises Flashcards

1
Q

What is machine learning?

A

Machine learning transforms human processes into intelligent, automated processes, which allows enterprises to focus their resources toward higher-value activities (like customer retention & acquisition)
 one of the must disruptive innovations and strong enabler of competitive advantage for businesses
 can reduce cost by between 20-25%
 can generate new revenues across products and services
 can improve customer retention and acquisition

Q

Whats the relationship between AI, machine learning and deep learning?

A

Artificial Intelligence (AI)= a broader domain than machine learning that includes speech and image recognition, natural-language processing (NLP), and object manipulation
–>AI is necessary for machine learning

Machine learning= a subset of artificial intelligence that can learn patterns from data without the need to define them a priority

Deep learning= is a subset of machine learning, employs a com-plex structure with many nodes, hidden units, and learning algorithms, all of which influence training time and quality of learning
–>Deep learning is expected to be at the center of the machine-learning field

Q

What are the three main machine-learning applications used by enterprises?

A

Clustering= used to group sets of objects on the basis of their similarities in a multidimensional space

Classification= the process of identifying the category or class of an observation

Prediction= Machine learning is used to identify patterns in data and to predict future events

Q

Between which two attributes exists a tradeoff?

A

-One of the challenges in choosing the best algorithm is managing the trade-off between accuracy and interpretability
–> Accuracy= measure of how well the algorithm will perform in practice
–>Interpretability= the ability to explain to users how a particular decision or response is made
–> trade-off between accuracy and interpretability arises for two reasons:
–>by adding more parameters, a model’s accuracy increases, but the outcomes become harder to understand and interpret

Q

What are potential types of errors?

A

-Reducible errors= originate from the fact that the chosen model will generally not be a perfect estimate of the true function, and this inaccuracy will introduce some errors
-Bias error= refers to errors introduced through faulty assumptions about the nature of the function
-Variance error= the amount by which the estimate of the function learned from one training data set would change if a different training dataset were used, occurs because of sensitivity to small fluctuations in the training data set
-Irreducible errors= even if a machine-learning algorithm were able to capture perfectly the true function, some errors would be irreducible because of inaccurate data and missing predictor variables

Q

What are challenges in deploying machine learning at enterprises?

A
  1. The ethical challenge:
    -When collecting training data, a company must take care to comply with data privacy and protection rules
  2. The storage of machine learning engineers
    -it will take years to adequately meet the industry demand for machine-learning-educated jobseekers
  3. The data quality challenge
    -When data are more unstructured and collected from more sources, data quality tends to decline
  4. The cost-benefit challenge
    -Since machine learning is not a solution for all business problems, managers need to have a clear understanding of its value-generation mechanism

Q

Whats the conclusion of the article?

A

As machine learning pervades, managers who learn early on about machine-learning tools and techniques can quickly identify opportunities and potential benefits, effectively communicate their potential to stakeholders, and bring competitive advantages to their enterprises
