Learning On The Border:Active Learning in Imbalanced classification Data萍華 楊
This paper proposes using active learning to address the problem of class imbalance in machine learning classification tasks. The key ideas are:
1) Active learning selects the most informative examples to label, which tend to be instances closest to the decision boundary. This helps provide a more balanced sample to the learner.
2) An online support vector machine (SVM) algorithm is used to allow efficient integration of newly labeled examples without retraining on the entire dataset.
3) Early stopping criteria based on support vectors are introduced to determine when enough examples have been labeled.
Empirical results on imbalanced datasets demonstrate that the active learning approach leads to improved classification performance compared to traditional supervised learning methods.

Efficient Similarity Computation for Collaborative Filtering in Dynamic Envir...Olivier Jeunen
This document proposes a new method called Dynamic Index for efficiently computing similarity between items in collaborative filtering recommendations. It computes item similarities incrementally as user-item interactions stream in, by maintaining counts of co-occurrences between items and individual item exposures. This approach is faster than baselines for sparse datasets and scales to large data volumes. Parallelizing the method yields further speedups. Additionally, restricting recommendations to a subset of recent items significantly improves efficiency without harming recommendation quality.
Automated machine learning (AutoML) systems can find the optimal machine learning algorithm and hyperparameters for a given dataset without human intervention. AutoML addresses the skills gap in data science by allowing data scientists to build more models in less time. On average, tuning hyperparameters results in a 5-10% improvement in accuracy over default parameters. However, the best parameters vary across problems. AutoML tools like Auto-sklearn use techniques like Bayesian optimization and meta-learning to efficiently search the hyperparameter space. Auto-sklearn has won several AutoML challenges due to its ability to effectively optimize over 100 hyperparameters.

A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

5. We are in era where…
• People worry that computers will get too smart and take over the world, but the real problem is
that they're too stupid and they've already taken over the world." (Pedro Domingos)
• Data is the key to unlocking machine learning, as much as machine learning is the key to unlocking
the insight hidden in data.
6. ->A Brief History of AI

10. What is it???
• Using data” is what is typically referred to as “training”, while
• “answering questions” is referred to as “making predictions”,
or “inference”.
• What connects these two parts together is the model. We
train the model to make increasingly better and more
useful predictions, using the our datasets.
• This predictive model can then be deployed to serve up
predictions on previously unseen data.
11. What is Machine Learning?
• Science of getting computers to learn without being explicitly
programmed.
• The world is filled with data.
• Machine learning brings the promise of deriving meaning from all of that
data.
• Field of computer science that uses statistical techniques to give
computer systems the ability to "learn" with data, without being
explicitly programmed.
13. One of the ways to define..
Field of computer science that uses statistical techniques to
give computer systems the ability to "learn" with data,
without being explicitly programmed.
14. Another definition: (Tom Mitchell)
Example: playing checkers.
E = the experience of playing many games of
checkers
T = the task of playing checkers.
P = the probability that the program will win the
next game.
A computer program is said to learn from
experience E w.r.t some task T and some
performance measure P if its performance on
T as measured by P improves with E
15. Training set and testing set
• Machine learning is about learning some properties of a data
set and applying them to new data.
• Data Split into two sets:
Training set on which we learn data properties
Testing set on which we test these properties.
16. Types of Learning
• Supervised (inductive) learning – Given: training data + desired outputs (labels). Learning with a labeled
trainingset Example: email classification with already labeled emails
• Unsupervised learning – Given: training data (without desired outputs). Discover patterns in unlabeled data
Example: cluster similar documents based on text
• Reinforcement learning – Rewards from sequence of actions, learn to act based on feedback/reward Example:
learn to play Go, reward: win or lose
17. Simple ML Program

Pip install numpy
Pip install pandas
pip install matplotlib
Pip install scikit_learn
Pip install scipy
Pip install opencv-python
Pip install librosa
Sample program: detection of good and bad wine.
18. Regression
• Regression searches for relationships among variables.
• Predict a value of a given continuous valued variable based on the values of other
variables, assuming a linear or nonlinear model of dependency.
• Greatly studied in statistics, neural network fields.
Examples: Predicting sales amounts of new product based on advetising expenditure.
Predicting wind velocities as a function of temperature, humidity, air pressure, etc.
Time series prediction of stock market indices.
19. Why Regression(contd..)
• The objective of a linear regression model is to find a relationship between one or more
features(independent variables) and a continuous target variable(dependent variable). When there is
only feature it is called Uni-variate Linear Regression and if there are multiple features, it is
called Multiple Linear Regression.
• The dependent features are called the dependent variables, outputs, or responses.
• The independent features are called the independent variables, inputs, or predictors.
• Typically, regression is needed to answer whether and how some phenomenon influences the other
or how several variables are related.
• Regression is also useful when you want to forecast a response using a new set of predictors.
• Example: predicting the housing price, economy, computer science, social sciences, and so on. Its
importance rises every day with the availability of large amounts of data and increased awareness of the
practical value of data.
20. Problem Formulation
• When implementing linear regression of some dependent variable 𝑦 on the set of independent variables
• 𝐱 = (𝑥₁, …, 𝑥ᵣ), where 𝑟 is the number of predictors,
• you assume a linear relationship between 𝑦 and 𝐱: 𝑦 = 𝛽₀ + 𝛽₁𝑥₁ + ⋯ + 𝛽ᵣ𝑥ᵣ + 𝜀. This equation is the regression equation. 𝛽₀, 𝛽₁, …, 𝛽ᵣ are
the regression coefficients, and 𝜀 is the random error.
• Linear regression calculates the estimators of the regression coefficients or simply the predicted weights, denoted with 𝑏₀, 𝑏₁, …, 𝑏ᵣ.
They define the estimated regression function 𝑓(𝐱) = 𝑏₀ + 𝑏₁𝑥₁ + ⋯ + 𝑏ᵣ𝑥ᵣ. This function should capture the dependencies between the
inputs and output sufficiently well.
• The estimated or predicted response, 𝑓(𝐱ᵢ), for each observation 𝑖 = 1, …, 𝑛, should be as close as possible to the corresponding actual
response 𝑦ᵢ. The differences 𝑦ᵢ - 𝑓(𝐱ᵢ) for all observations 𝑖 = 1, …, 𝑛, are called the residuals. Regression is about determining the best
predicted weights, that is the weights corresponding to the smallest residuals.
• To get the best weights, you usually minimize the sum of squared residuals (SSR) for all observations 𝑖 = 1, …, 𝑛: SSR = Σᵢ(𝑦ᵢ - 𝑓(𝐱ᵢ))². This
approach is called the method of ordinary least squares.
• output (y) can be calculated from a linear combination of the input variables (X). When there is a single input variable, the method is
referred to as a simple linear regression.
21. Linear Regression with One
Variable & Python functions
Programming
Simple Linear Regression
Simple or single-variate linear regression is the simplest case of linear regression with a
single independent variable, 𝐱 = 𝑥.
The following figure illustrates simple linear regression:
• When implementing simple linear regression,
you typically start with a given set of input-
output (𝑥-𝑦) pairs (green circles).
• The estimated regression function (black line) has
the equation 𝑓(𝑥) = 𝑏₀ + 𝑏₁𝑥.
• The predicted responses (red squares) are the
points on the regression line that correspond to
the input values.
• The residuals (vertical dashed gray lines) can be
calculated as 𝑦ᵢ - 𝑓(𝐱ᵢ) = 𝑦ᵢ - 𝑏₀ - 𝑏₁𝑥ᵢ for 𝑖 = 1, …, 𝑛.
22. Linear Regression with Multiple Variables
• Multiple or multivariate linear regression is a case of linear regression with two or
more independent variables.
• If there are just two independent variables, the estimated regression function is 𝑓(𝑥
₁, 𝑥₂) = 𝑏₀ + 𝑏₁𝑥₁ + 𝑏₂𝑥₂. It represents a regression plane in a three-dimensional
space. The goal of regression is to determine the values of the weights 𝑏₀, 𝑏₁, and
𝑏₂ such that this plane is as close as possible to the actual responses and yield the
minimal SSR.
• The case of more than two independent variables is similar, but more general. The
estimated regression function is 𝑓(𝑥₁, …, 𝑥ᵣ) = 𝑏₀ + 𝑏₁𝑥₁ + ⋯ +𝑏ᵣ𝑥ᵣ, and there
23. Logistic Regression
• Logistic Regression is used when the
dependent variable(target) is categorical.
• Consider a scenario where we need to
classify whether an email is spam or not.
25. Unsupervised Learning
• No labels are given to the learning algorithm, leaving it on its own to find
structure in its input. Unsupervised learning can be a goal in itself
(discovering hidden patterns in data) or a means towards an end (feature
learning)..
• In some pattern recognition problems, the training data consists of a set of
input vectors x without any corresponding target values. The goal in such
unsupervised learning problems may be to discover groups of similar
examples within the data, where it is called clustering, or to determine how
the data is distributed in the space, known as density estimation.
26. Why Unsupervised Learning
• Annotating large datasets is very costly and hence we can
label only a few examples manually. Example: Speech
Recognition
• There may be cases where we don’t know how many/what
classes is the data divided into. Example: Data Mining
• We may want to use clustering to gain some insight into the
structure of the data before designing a classifier.
27. What is Clustering
Clustering can be considered the most important unsupervised
learning problem; so, as every other problem of this kind, it deals with finding
a structure in a collection of unlabeled data. A loose definition of clustering could
be “the process of organizing objects into groups whose members are similar in
some way”. A cluster is therefore a collection of objects which are “similar”
between them and are “dissimilar” to the objects belonging to other clusters.
28. Goal of Clustering
The goal of clustering is to determine the internal grouping in a set of
unlabeled data. But how to decide what constitutes a good clustering? It can
be shown that there is no absolute “best” criterion which would be independent
of the final aim of the clustering.
29. Proximity Measures
• For clustering, we need to define a proximity measure for two data
points. Proximity here means how similar/dissimilar the samples are
with respect to each other.
• Similarity measure S(xi,xk): large if xi,xk are similar
• Dissimilarity(or distance) measure D(xi,xk): small if xi,xk are similar
30. K-Means Clustering
• The procedure follows a simple and easy way to classify a given data set through a certain number of clusters
(assume k clusters) fixed a priori. The main idea is to define k centres, one for each cluster.
• These centroids should be placed in a smart way because of different location causes different result.
• The next step is to take each point belonging to a given data set and associate it to the nearest centroid.
• At this point we need to re-calculate k new centroids as barycenters of the clusters resulting from the previous
step. After we have these k new centroids, a new binding has to be done between the same data set points and
the nearest new centroid.
• A loop has been generated. As a result of this loop we may notice that the k centroids change their location step
by step until no more changes are done.
• Finally, this algorithm aims at minimizing an objective function, in this case a squared error function. The objective
function.
31. Algorithm Steps
The algorithm is composed of the following steps:
• Let X = {x1,x2,x3,……..,xn} be the set of data points and V = {v1,v2,…….,vc} be the set of
centers.
• Randomly select ‘c’ cluster centers.
• Calculate the distance between each data point and cluster centers.
• Assign the data point to the cluster center whose distance from the cluster center is minimum of
all the cluster centers.
• Recalculate the new cluster center using:
where, ‘ci’ represents the number of data points in ith cluster.
• Recalculate the distance between each data point and new obtained cluster centers.
• If no data point was reassigned then stop, otherwise repeat from step 3).
