This slide provides an overview of some of the core concepts related to building machine learning models. Machine learning is a branch of computer science that aims to make computers learn from data without being explicitly programmed. Learning problems can be classified into three main types: supervised learning, unsupervised learning, and reinforcement learning. Supervised learning involves learning a function that maps inputs to outputs, given a set of labeled examples. Unsupervised learning involves finding patterns or structure in unlabeled data. Reinforcement learning involves learning how to act or behave in an environment, given feedback or rewards from the environment.
Other important concepts related to machine learning include generalization, overfitting, representation, features, models, evaluation, optimization, bias-variance tradeoff, and Occam's razor. Generalization refers to the ability of a machine learning model to perform well on new or unseen data, not just on the training data. Overfitting occurs when a model fits the training data too closely, resulting in poor generalization. Representation refers to the way of encoding or describing the input and output data for a machine learning problem. Features are the attributes or characteristics of the input data that are used for learning. Models are the mathematical or computational structures that represent or approximate the function that maps inputs to outputs. Evaluation involves measuring the performance or accuracy of a machine learning model on a given data set. Optimization involves finding the best or optimal parameters or settings for a machine learning model that minimize the error or maximize the accuracy on the training data. Bias-variance tradeoff refers to the balance between model complexity and generalization ability. Occam's razor is a principle that favors simpler explanations or models when competing hypotheses explain the data equally well.
Understanding these core concepts is crucial for anyone who wants to learn and apply machine learning in practice. This slide provides a concise summary of these concepts and can serve as a useful reference for beginners and experts alike.

CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!
Work done in cooperation with James Malloy and David Moelling from Tetra Engineering.

Immunizing Image Classifiers Against Localized Adversary Attacksgerogepatton
This paper addresses the vulnerability of deep learning models, particularly convolutional neural networks
(CNN)s, to adversarial attacks and presents a proactive training technique designed to counter them. We
introduce a novel volumization algorithm, which transforms 2D images into 3D volumetric representations.
When combined with 3D convolution and deep curriculum learning optimization (CLO), itsignificantly improves
the immunity of models against localized universal attacks by up to 40%. We evaluate our proposed approach
using contemporary CNN architectures and the modified Canadian Institute for Advanced Research (CIFAR-10
and CIFAR-100) and ImageNet Large Scale Visual Recognition Challenge (ILSVRC12) datasets, showcasing
accuracy improvements over previous techniques. The results indicate that the combination of the volumetric
input and curriculum learning holds significant promise for mitigating adversarial attacks without necessitating
adversary training.
3. What is Machine Learning ?
• Machine learning is an subfield of artificial intelligence
(AI) that provides systems the ability to automatically
learn and improve from experience without being
explicitly programmed.
• Machine learning focuses on the development of computer
programs that can access data and use it learn for
themselves.
4. How Machine Learning Works?
• The Machine Learning process starts with inputting training
data into the selected algorithm. Training data being known
or unknown data to develop the final Machine Learning
algorithm.
• To test whether this algorithm works correctly, new input
data is fed into the Machine Learning algorithm. The
prediction and results are then checked.
5. How Machine Learning Works?
• If the prediction is not as expected, the algorithm is re-
trained multiple numbers of times until the desired
output is found.
• This enables the Machine Learning algorithm to
continually learn on its own and produce the most
optimal answer that will gradually increase in accuracy
over time.
6. Difference Between AI, ML, DL
• Artificial Intelligence (AI) is an umbrella discipline that
covers everything related to making machines smarter.
• Machine Learning (ML) is commonly used along with
AI but it is a subset of AI. ML refers to an AI system
that can self-learn based on the algorithm.
• Deep Learning (DL) is a machine learning applied to
large data sets.
8. Supervised Learning
• Supervised Learning describes a class of
problem that involves using a model to
learn a mapping between input examples
and the target variable.
• Models are fit on training data comprised of inputs and outputs and used
to make predictions on test sets where only the inputs are provided and
the outputs from the model are compared to the withheld target variables
and used to estimate the skill of the model.
9. Supervised Learning problems can be divided into
two categories:
Supervised
Learning
Regression
Classification
Regression is the task of
predicting a numerical
label.
Classification is the
task of predicting a
class label.

11. Unsupervised Learning
• Unsupervised learning describes a
class of problems that involves
using a model to describe or
extract relationships in data.
• Compared to supervised learning, unsupervised learning operates
upon only the input data without outputs or target variables. As such,
unsupervised learning does not have a teacher correcting the model, as
in the case of supervised learning.
12. Unsupervised Learning problems can be divided
into two categories:
Clustering
Dimensionality
Reduction
Clustering involves the
finding of groups in data.
Seeks a lower-dimensional
representation of numerical
input data that preserves the
salient relationships in the data.

14. Reinforcement Learning
• Reinforcement learning describes a
class of problems where an agent
operates in an environment and
must learn to operate using
feedback.
• Reinforcement learning is learning what to do — how to map
situations to actions—so as to maximize a numerical reward signal.
The learner is not told which actions to take, but instead must
discover which actions yield the most reward by trying them.
