Deep learning: the future of recommendationsBalázs Hidasi
An informative talk about deep learning and its potential uses in recommender systems. Presented at the Budapest Startup Safary, 21 April, 2016.
The breakthroughs of the last decade in neural network research and the quick increasing of computational power resulted in the revival of deep neural networks and the field focusing on their training: deep learning. Deep learning methods have succeeded in complex tasks where other machine learning methods have failed, such as computer vision and natural language processing. Recently deep learning has began to gain ground in recommender systems as well. This talk introduces deep learning and its applications, with emphasis on how deep learning methods can solve long standing recommendation problems.
生成式對抗網路 (Generative Adversarial Network, GAN) 顯然是深度學習領域的下一個熱點,Yann LeCun 說這是機器學習領域這十年來最有趣的想法 (the most interesting idea in the last 10 years in ML),又說這是有史以來最酷的東西 (the coolest thing since sliced bread)。生成式對抗網路解決了什麼樣的問題呢?在機器學習領域,回歸 (regression) 和分類 (classification) 這兩項任務的解法人們已經不再陌生,但是如何讓機器更進一步創造出有結構的複雜物件 (例如:圖片、文句) 仍是一大挑戰。用生成式對抗網路,機器已經可以畫出以假亂真的人臉,也可以根據一段敘述文字,自己畫出對應的圖案,甚至還可以畫出二次元人物頭像 (左邊的動畫人物頭像就是機器自己生成的)。本課程希望能帶大家認識生成式對抗網路這個深度學習最前沿的技術。
A fast-paced introduction to Deep Learning concepts, such as activation functions, cost functions, back propagation, and then a quick dive into CNNs. Basic knowledge of vectors, matrices, and derivatives is helpful in order to derive the maximum benefit from this session.

It’s long ago, approx. 30 years, since AI was not only a topic for Science-Fiction writers, but also a major research field surrounded with huge hopes and investments. But the over-inflated expectations ended in a subsequent crash and followed by a period of absent funding and interest – the so-called AI winter. However, the last 3 years changed everything – again. Deep learning, a machine learning technique inspired by the human brain, successfully crushed one benchmark after another and tech companies, like Google, Facebook and Microsoft, started to invest billions in AI research. “The pace of progress in artificial general intelligence is incredible fast” (Elon Musk – CEO Tesla & SpaceX) leading to an AI that “would be either the best or the worst thing ever to happen to humanity” (Stephen Hawking – Physicist).

Either a new AI “winter is coming” (Ned Stark – House Stark) or this new wave of innovation might turn out as the “last invention humans ever need to make” (Nick Bostrom – AI Philosoph). Or maybe it’s just another great technology helping humans to achieve more.

Generating Natural-Language Text with Neural NetworksJonathan Mugan
Automatic text generation enables computers to summarize text, to have conversations in customer-service and other settings, and to customize content based on the characteristics and goals of the human interlocutor. Using neural networks to automatically generate text is appealing because they can be trained through examples with no need to manually specify what should be said when. In this talk, we will provide an overview of the existing algorithms used in neural text generation, such as sequence2sequence models, reinforcement learning, variational methods, and generative adversarial networks. We will also discuss existing work that specifies how the content of generated text can be determined by manipulating a latent code. The talk will conclude with a discussion of current challenges and shortcomings of neural text generation.

In this deck from the HPC Knowledge Portal 2017 Conference, Rob Farber from TechEnablement presents: State-Of-The Art Machine Learning Algorithms and How They Are Affected By Near-Term Technology Trends.
"Industry and Wall Street projections indicate that Machine Learning will touch every piece of data in the data center by 2020. This has created a technology arms race and algorithmic competition as IBM, NVIDIA, Intel, and ARM strive to dominate the retooling of the computer industry to support ubiquitous machine learning workloads over the next 3-4 years. Similarly, algorithm designers compete to create faster and more accurate training and inference techniques that can address complex problems spanning speech, image recognition, image tagging, self-driving cars, data analytics and more. The challenges for researchers and technology providers encompass big data, massive parallelism, distributed processing, and real-time processing. Deep-learning and low-precision inference (based on INT8 and FP16 arithmetic) are current hot topics."

Getting Started with Keras and TensorFlow - StampedeCon AI Summit 2017StampedeCon
This technical session provides a hands-on introduction to TensorFlow using Keras in the Python programming language. TensorFlow is Google’s scalable, distributed, GPU-powered compute graph engine that machine learning practitioners used for deep learning. Keras provides a Python-based API that makes it easy to create well-known types of neural networks in TensorFlow. Deep learning is a group of exciting new technologies for neural networks. Through a combination of advanced training techniques and neural network architectural components, it is now possible to train neural networks of much greater complexity. Deep learning allows a model to learn hierarchies of information in a way that is similar to the function of the human brain.
Emotion recognition using image processing in deep learningvishnuv43
User’s emotion using its facial expressions will be detected. These expressions can be derived from the live feed via system's camera or any pre-existing image available in the memory. Emotions possessed by humans can be recognized and has a vast scope of study in the computer vision industry upon which several researches have already been done.
We propose a compact CNN model for facial expression recognition.
The work has been implemented using Python Open Source Computer Vision Library (OpenCV) and NumPy,pandas,keras packages. The scanned image (testing dataset) is being compared to training dataset and thus emotion is predicted.

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.
NUMERICAL SIMULATIONS OF HEAT AND MASS TRANSFER IN CONDENSING HEAT EXCHANGERS...ssuser7dcef0
Power plants release a large amount of water vapor into the
atmosphere through the stack. The flue gas can be a potential
source for obtaining much needed cooling water for a power
plant. If a power plant could recover and reuse a portion of this
moisture, it could reduce its total cooling water intake
requirement. One of the most practical way to recover water
from flue gas is to use a condensing heat exchanger. The power
plant could also recover latent heat due to condensation as well
as sensible heat due to lowering the flue gas exit temperature.
Additionally, harmful acids released from the stack can be
reduced in a condensing heat exchanger by acid condensation. reduced in a condensing heat exchanger by acid condensation.
Condensation of vapors in flue gas is a complicated
phenomenon since heat and mass transfer of water vapor and
various acids simultaneously occur in the presence of noncondensable
gases such as nitrogen and oxygen. Design of a
condenser depends on the knowledge and understanding of the
heat and mass transfer processes. A computer program for
numerical simulations of water (H2O) and sulfuric acid (H2SO4)
condensation in a flue gas condensing heat exchanger was
developed using MATLAB. Governing equations based on
mass and energy balances for the system were derived to
predict variables such as flue gas exit temperature, cooling
water outlet temperature, mole fraction and condensation rates
of water and sulfuric acid vapors. The equations were solved
using an iterative solution technique with calculations of heat
and mass transfer coefficients and physical properties.
Using recycled concrete aggregates (RCA) for pavements is crucial to achieving sustainability. Implementing RCA for new pavement can minimize carbon footprint, conserve natural resources, reduce harmful emissions, and lower life cycle costs. Compared to natural aggregate (NA), RCA pavement has fewer comprehensive studies and sustainability assessments.

Hierarchical Digital Twin of a Naval Power SystemKerry Sado
A hierarchical digital twin of a Naval DC power system has been developed and experimentally verified. Similar to other state-of-the-art digital twins, this technology creates a digital replica of the physical system executed in real-time or faster, which can modify hardware controls. However, its advantage stems from distributing computational efforts by utilizing a hierarchical structure composed of lower-level digital twin blocks and a higher-level system digital twin. Each digital twin block is associated with a physical subsystem of the hardware and communicates with a singular system digital twin, which creates a system-level response. By extracting information from each level of the hierarchy, power system controls of the hardware were reconfigured autonomously. This hierarchical digital twin development offers several advantages over other digital twins, particularly in the field of naval power systems. The hierarchical structure allows for greater computational efficiency and scalability while the ability to autonomously reconfigure hardware controls offers increased flexibility and responsiveness. The hierarchical decomposition and models utilized were well aligned with the physical twin, as indicated by the maximum deviations between the developed digital twin hierarchy and the hardware.
11. Deep Learning Today
• Advancement in speech recognition in the last 2 years
• A few long-standing performance records were broken with deep learning methods
• Microsoft and Google have both deployed DL-based speech recognition systems in
their products
• Advancement in Computer Vision
• Feature engineering is the bread-and-butter of a large portion of the CV community,
which creates some resistance to feature learning
• But the record holders on ImageNet and Semantic Segmentation are convolutional
nets
• Advancement in Natural Language Processing
• Fine-grained sentiment analysis, syntactic parsing
• Language model, machine translation, question answering

Engine management
• The behaviour of a car engine is influenced
by a large number of parameters
– temperature at various points
– fuel/air mixture
– lubricant viscosity.
• Major companies have used neural networks
to dynamically tune an engine depending on
current settings.
14. 14
Signature recognition
• Each person's signature is different.
• There are structural similarities which are
difficult to quantify.
• One company has manufactured a machine
which recognizes signatures to within a high
level of accuracy.
– Considers speed in addition to gross shape.
– Makes forgery even more difficult.
15. 15
Sonar target recognition
• Distinguish mines from rocks on sea-bed
• The neural network is provided with a large
number of parameters which are extracted
from the sonar signal.
• The training set consists of sets of signals
from rocks and mines.
16. 16
Stock market prediction
• “Technical trading” refers to trading based
solely on known statistical parameters; e.g.
previous price
• Neural networks have been used to attempt
to predict changes in prices.
• Difficult to assess success since companies
using these techniques are reluctant to
disclose information.
17. 17
Mortgage assessment
• Assess risk of lending to an individual.
• Difficult to decide on marginal cases.
• Neural networks have been trained to make
decisions, based upon the opinions of expert
underwriters.
• Neural network produced a 12% reduction in
delinquencies compared with human experts.
22. Limitations of Neural Networks
Random initialization + densely connected networks lead to:
• High cost
• Each neuron in the neural network can be considered as a logistic regression.
• Training the entire neural network is to train all the interconnected logistic regressions.
• Difficult to train as the number of hidden layers increases
• Recall that logistic regression is trained by gradient descent.
• In backpropagation, gradient is progressively getting more dilute. That is, below top layers,
the correction signal 𝛿" is minimal.
• Stuck in local optima
• The objective function of the neural network is usually not convex.
• The random initialization does not guarantee starting from the proximity of global optima.
• Solution:
• Deep Learning/Learning multiple levels of representation

Repeat this thousands, maybe millions of times – each time
taking a random training instance, and making slight
weight adjustments
Algorithms for weight adjustment are designed to make
changes that will reduce the error

62. Backpropagation Algorithm – Main
Idea – error in hidden layers
The ideas of the algorithm can be summarized as follows :
1. Computes the error term for the output units using the
observed error.
2. From output layer, repeat
- propagating the error term back to the previous layer
and
- updating the weights between the two layers
until the earliest hidden layer is reached.
63. Backpropagation Algorithm
• Initialize weights (typically random!)
• Keep doing epochs
• For each example e in training set do
• forward pass to compute
• O = neural-net-output(network,e)
• miss = (T-O) at each output unit
• backward passto calculate deltas to weights
• update all weights
• end
• until tuning set error stops improving

69. Bias
Each neuron is like a simple logistic regression and you
have y=σ(Wx+b). The input values are multiplied with the
weights and the bias affects the initial level of squashing
in the sigmoid function (tanh etc.), which results the
desired the non-linearity.
For example, assume that you want a neuron to
fire y≈1 when all the input pixels are black x≈0. If there is
no bias no matter what weights W you have, given the
equation y=σ(Wx) the neuron will always fire y≈0.5.
