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.

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).
What sparked this new Hype? How is Deep Learning different from previous approaches? Are the advancing AI technologies really a threat for humanity? Let’s look behind the curtain and unravel the reality. This talk will explore why Sundar Pichai (CEO Google) recently announced that “machine learning is a core transformative way by which Google is rethinking everything they are doing” and explain why "Deep Learning is probably one of the most exciting things that is happening in the computer industry” (Jen-Hsun Huang – CEO NVIDIA).
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.

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.
Cosmetic shop management system project report.pdfKamal Acharya
Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers. It should help the employees to quickly identify the list of cosmetic product that have reached the minimum quantity and also keep a track of expired date for each cosmetic product. It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.
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.

48. BEYOND MACHINE INTELLIGENCE :
TWO PATHWAYS
• Currently there are two main approaches to generating images using artificial intelligence
– Boltzmann Machine
– Generative Adversarial Neural Networks ( GAN)
• GAN pits two neural networks against one another in order to improve their generation of photorealistic images.
• In GAN, there is a generator which produces fake images, and a discriminator, which differentiates the fake images
from the real ones.They train together: the discriminator processes the variations between the real and the fake
images and informs the generator on how to produce more accurate fake images.
– Variational Auto Encoding (VAE)
• VAE has strong ability to generate diverse set of images
• Essentially autoencoder performs a dimensionality reduction in your data set.
– Some researchers have combinedVAE and GAN into a hybrid for an improved generative model

• This can be used for visualizations to understand the emergent structure of the neural
network better, and is the basis for the DeepDream concept.
• The optimization resembles Backpropagation, however instead of adjusting the network
weights, the weights are held fixed and the input is adjusted.
57. DEEP DREAM - INFERENCES
• Once trained, the network can also be run in reverse, being asked to adjust the original image
slightly so that a given output neuron (e.g. the one for faces or certain animals) yields a higher
confidence score.
• However, after enough reiterations, even imagery initially devoid of the sought features will be
adjusted enough that a form of pareidolia results, by which psychedelic and surreal images are
generated algorithmically.
• Applying gradient descent independently to each pixel of the input produces images in which
adjacent pixels have little relation and thus the image has too much high frequency information.
• The generated images can be greatly improved by including a prior or regularizer that prefers inputs
that have natural image statistics (without a preference for any particular image), or are simply
smooth.The total variation regularizer prefers images that are piecewise constant.

60. NATURE OF ADVERSARIAL IMAGES
• Research on adversarial images to date has focused on disrupting classification, i.e., producing
images classified with labels that are patently inconsistent with human perception.
• Specifically, given a source image, a target (guide) image, and a trained DNN, we find small
perturbations to the source image that cause the representation on a specified layer (or
above) to be remarkably similar to that of the guide image, and hence far from that of the
source.
• Deep representations of such adversarial images are not outliers per se, rather, they appear
generic, indistinguishable from representations of natural images
61. EVOLUTIONARY ALGORITHMS AND
ADVERSARIAL IMAGES
• Evolutionary algorithms has been used to generate images comprising of 2D patterns that are
classified by DNNs as common objects with high confidence
• Such adversarial images are quite different from the natural images which are used as training
data
• Because natural images only occupy a small volume of the space of all possible images, it is not
surprising that discriminative DNNs trained on natural images have trouble coping with such
out of sample data.
62. ANALYSIS OF APPARENT QUASI-
NATURAL ADVERSARIAL IMAGES
• We need to use gradient based optimization on the classification loss with respect to the image
perturbation
– The magnitude of the perturbation is penalized to ensure that the perturbation is not perceptually salient
– Given an Image I, a DNN Classifier f, and an erroneous label L, they find the perturbation e that minimizes
loss ( f ( I + e ) L ) + c || e || 2.
– c will be chosen to fins the smallest e that achieves f ( I + e ) = L
– Resulting adversarial images occupy low probability pockets in the manifold, acting like blind spots to the
DNN
– Ian Goodfellow et. al showed that adversarial images are more common and can be found by taking steps
in the direction of gradient of loss ( f ( I + e ) , L )
– Ian Goodfellow et.al showed that adversarial images exist for other models, including linear classifiers
– They argue that the problems arises when the models are too linear

Adversaries can craft particular inputs, named
adversarial samples, leading models to produce
an output behavior of their choice, such as
misclassification.
Inputs are crafted by adding a carefully chosen
adversarial perturbation to a legitimate sample.
The resulting sample is not necessarily
unnatural, i.e. outside of the training data
manifold.Algorithms
crafting adversarial samples are designed to
minimize the perturbation, thus making
adversarial samples hard to distinguish from
legitimate samples.
Attacks based on adversarial samples occur
after training is complete and therefore, do
not require any tampering with the training
procedure.

Recent studies have shown that
deep learning, like other machine
learning techniques, is vulnerable to
adversarial samples: inputs crafted to
force a deep neural network (DNN)
to provide adversary-selected
outputs.
Such attacks can seriously undermine
the security of the system supported by
the DNN, sometimes with devastating
consequences.
For example, autonomous vehicles can
be crashed, illicit or illegal content can
bypass content filters, or biometric
authentication systems can be
manipulated to allow improper access.

72. ADVERSARIAL IMAGE CONSTRUCTION
• Let I(s) and I(g) denote the source and guide images. Let Ø(k) be the mapping from an image to its
internal DNN representation at layer K. Our goal is to find a new image, I(a) such that the Euclidean
distance between Ø(k)I(s) and Ø(k) I(g) is as small as possible and I(a) remains close to the source I(s).
• More precisely, I(a) is defined to be the solution to a constrained optimization problem
• I(a) = arg min || Ø(k)I - Ø(k)I(g) || 2 – 2, subject to || I – Is || ∞ < ∂.
• The constraint on the distance between I (a) and I (s) is formulated in terms of L∞ norm to limit the
maximum deviation of any single pixel color to ∂.
• Inspecting the adversarial images, one can see that larger values of ∂ allow more noticeable
perturbations .
• Interestingly, no natural image was found in which guide image is perceptible in the adversarial image. Nor
is there a significant amount of salient structure found in the difference images.Adversarial Images
generated from one network are usually misclassified by other networks.

One successful approach has been to
invert the mapping, allowing us to
display images reconstructed from
internal representation at specific layers
While the lower layer representations
bear similarity to the source, the upper
layers are remarkably similar to the
guide.
Generally, we find that the internal
representations begin to mimic the
guide at whatever layer was targeted by
the optimization
Hence it is interesting to see that the
human perception and the internal
representation of these adversarial
images are clearly incongruent.

Intersection of NNs is another
useful similarity measure.
Two nearby points should also have
similar distance to their NNs.
To use this measure of similarity, we
take the average distance to K NN
as a scalar score for a point, and
then rank that point along with the
true positive training point in its
label class

adversaries via optimization

76. SPARSITY AND ADVERSARIAL
CONSTRUCTION METHODS
• If the degree of sparsity increases after the adversarial perturbation, the adversarial example is
using extra active paths to manipulate the resulting representation.
• We can analyze how much activate units are shared between source and the adversary, as well
as guide and adversary, by computing the intersection over union I/U of active units.
• If the I/U is high on all layers, the two representations share most active paths
• On the other hand, if I/U is low, while the degree of sparsity remains the same, then the
adversary must have closed some activation paths

78. WHY RANDOMNESS IS
IMPORTANT FOR DEEP LEARNING
• Random Noise allows neural nets to produce multiple outputs given same instance of input
• Random noise limits the amount of information flowing through the network, forcing the
network to learn meaningful representations of data.
• Random noise provides "exploration energy" for finding better optimization solutions during
gradient descent.
• Adding Gradient Noise helps to
– Helps to void overfitting
– Help to lower training loss
– Reduction in error rate
79. TOPIC OF DISCUSSION :
DEFENSIVE DISTILLATION
• Aiming to reduce the effectiveness of adversarial samples on DNNs.
• The study shows that defensive distillation can reduce effectiveness of sample creation from
95% to less than 0.5% on a studied DNN.
• Such dramatic gains can be explained by the fact that distillation leads gradients used in
adversarial sample creation to be reduced by a factor of 10 30.
• Distillation increases the average minimum number of features that need to be modified to
create adversarial samples by about 800% on one of the DNNs.
80. NATURE OF ADVERSARIAL ATTACKS
• Inputs are crafted by adding a carefully chosen adversarial perturbation to a legitimate sample.
• The resulting sample is not necessarily unnatural, i.e. outside of the training data manifold.
• Algorithms crafting adversarial samples are designed to minimize the perturbation, thus making
adversarial samples hard to distinguish from legitimate samples.
• Attacks based on adversarial samples occur after training is complete and therefore do not
require any tampering with the training procedure.
• Attacks based on adversarial samples were primarily exploiting gradients computed to
estimate the sensitivity of networks to its input dimensions.
81. ADVERSARIAL DEEP LEARNING
• Simple confidence reduction
– The aim is to reduce a DNN’s confidence on a prediction, thus introducing class ambiguity
• Source-target misclassification
– The goal is to be able to take a sample from any source class and alter it so as to have
the DNN classify it in any chosen target class distinct from the source class.
• Examples :
– Potential examples of adversarial samples in realistic contexts could include slightly altering
malware executables in order to evade detection systems built using DNNs
– adding perturbations to handwritten digits on a check resulting in a DNN wrongly
recognizing the digits (for instance, forcing the DNN to read a larger amount than
written on the check)
– altering a pattern of illegal financial operations to prevent it from being picked up by
fraud detections systems using DNNs.
83. ESSENCE OF DISTILLATION METHOD
• Distillation is a training procedure initially designed to train a DNN using knowledge
transferred from a different DNN.
• The motivation behind the knowledge transfer operated by distillation is to reduce the
computational complexity of DNN architectures by transferring knowledge from larger
architectures to smaller ones.
• This facilitates the deployment of deep learning in resource constrained devices (e.g.
smartphones) which cannot rely on powerful GPUs to perform computations.
84. DEFENSIVE DISTILLATION APPROACH
• A new variant of distillation to provide for defense training: instead of transferring knowledge
between different architectures, it is proposed to use the knowledge extracted from a DNN
to improve its own resilience to adversarial samples.
• We can use the knowledge extracted during distillation to reduce the amplitude of network
gradients exploited by adversaries to craft adversarial samples.
• If adversarial gradients are high, crafting adversarial samples becomes easier because small
perturbations will induce high DNN output variations.
• To defend against such perturbations, one must therefore reduce variations around the input,
and consequently the amplitude of adversarial gradients.
• In other words, we use defensive distillation to smooth the model learned by a DNN architecture
during training by helping the model generalize better to samples outside of its training dataset.
85. NEURAL NETWORK DISTILLATION
• Distillation is motivated by the end goal of reducing the size of DNN architectures or
ensembles of DNN architectures, so as to reduce their computing resource needs, and in turn
allow deployment on resource constrained devices like smartphones.
• The general intuition behind the technique is to extract class probability vectors produced by a
first DNN or an ensemble of DNNs to train a second DNN of reduced dimensionality
without loss of accuracy.
• This intuition is based on the fact that knowledge acquired by DNNs during training is not
only encoded in weight parameters learned by the DNN but is also encoded in the
probability vectors produced by the network
86. DISTILLATION AND
NEURAL NETWORK ARCHITECTURE
• Distillation extracts class knowledge from these probability vectors to transfer it into a
different DNN architecture during training.
• To perform this transfer, distillation labels inputs in the training dataset of the second DNN
using their classification predictions according to the first DNN.
• The probability vectors produced by the first DNN are then used to label the dataset.
These new labels are called soft labels as opposed to hard class labels
87. BUILDING A ROBUST DNN
• A robust DNN should
– Display good accuracy inside and outside of its training dataset
– Model a smooth classifier function (F) which would intuitively classify inputs relatively
consistently in the neighborhood of a given sample.
– The larger this neighborhood is for all inputs within the natural distribution of samples, the
more robust is the DNN.
• The higher the average minimum perturbation required to misclassify a sample from
the data manifold is, the more robust the DNN is to adversarial samples.
