The document discusses new techniques in artificial intelligence for analyzing financial markets. It introduces the A.I.4Trading project which uses machine learning and deep learning models to extract patterns from market data and provide forecasts. The Market Clock module uses clustering and classification algorithms to analyze intraday price movements and predict the probability distribution of the market's end-of-day return. By recognizing patterns in historical market trajectories, the models aim to forecast the most probable trajectory of prices for the rest of the trading day.
Smart Data Webinar: Machine Learning UpdateDATAVERSITY
Machine Learning (ML) approaches and their supporting technologies can generally be classified as Supervised vs Unsupervised, and within those categories as General or Deep Learning (with Reinforcement Learning as a special case within Supervised Learning). The approaches may be based on biological models or statistical models, or hybrids. As demand for machine learning functionality in consumer and enterprise applications increases, it becomes important to have a framework for comparing ML products and services.
This webinar will present an overview of the machine learning landscape, from platform providers to point solutions in each major ML category, and help participants understand their options for experimentation and deployment of ML-based applications.
How to Build a Faster, Laser-Sharp SOC with Intelligent OrchestrationIBM Security
To keep pace with cyberattacks, organizations have long sought ways to operationalize security and respond faster to threats. But with increasingly complex IT environments and a growing skills shortage, doing so is easier said than done.
That’s where Intelligent Orchestration can help. Intelligent Orchestration integrates your existing security tools and guides SOC analysts through a fast and laser-focused response by combining case management, human and cyber intelligence, and incident response orchestration and automation.

In the token transfer, the risk of replay attack cannot be completely avoided when the sender's signatures are abused, which can bring the loss to users. And the reason is that the applying scope of the signatures is not properly designed in the smart contracts. To test and verify this loophole, we selected two similar smart contracts for our experiment, at the same time, we used our own accounts in these two contracts to carry out the experiment. Because the same signatures of the two contracts were used in the experiment, we got a double income from sender successfully.
The experiment verified that the replay attack is really exist. Besides, the replay attack may exist in multiple smart contracts. We calculated the number of smart contracts with this loophole, as well as the corresponding transaction activities, which find some Ethereum smart contracts are risked for this loophole. According to the vulnerability of the contract signature, the risk level is calibrated and depicted. Furthermore, the replay attack pattern is extended to within contract, cross contract and cross chain, which provide the pertinence and well reference for protection. Finally, the countermeasures are proposed to fix this vulnerability.

Applications of Artificial Neural Network in Forecasting of Stock Market Indexpaperpublications3
Abstract: Prediction in any field is a challenging and unnerving process. Stock market is a promising financial investment that can generate great wealth. However, under the impact of Globalization Stock Market Prediction (SMP) accuracy has become more challenging and rewarding for the researchers and participants in the stock market. Artificial Neural Networks (ANN) have been found to be an efficient tool in modeling stock prices and quite a large number of studies have been done on it. ANN modeling of stock prices of selected stocks under NSE is attempted to predict the next day’s price. The network developed consists of one input layer, hidden layer and output layer with four, nine and one nodes respectively. The input being the closing price of the previous four days and output being the price for the next day. In the first section the adaptability of neural networks in stock market prediction is discussed, in the second section we discuss the traditional methods that were being used earlier for stock market prediction, in the third section we discuss the justification for using neural networks and how it is better over traditional methods, in the fourth section we discuss the basics of neural networks, section five gives an overview of data and methodology being used, in section six we have discussed the various forecasting errors methods to calculate the error, in section seven we have presented our results. The aim of this paper is to provide an overview of the application of artificial neural network in stock market prediction.

In the recent years the scope of data mining has evolved into an active area of research because of the previously unknown and interesting knowledge from very large database collection. The data mining is applied on a variety of applications in multiple domains like in business, IT and many more sectors. In Data Mining the major problem which receives great attention by the community is the classification of the data. The classification of data should be such that it could be they can be easily verified and should be easily interpreted by the humans. In this paper we would be studying various data mining techniques so that we can find few combinations for enhancing the hybrid technique which would be having multiple techniques involved so enhance the usability of the application. We would be studying CHARM Algorithm, CM-SPAM Algorithm, Apriori Algorithm, MOPNAR Algorithm and the Top K Rules.

when will pi network coin be available on crypto exchange.DOT TECH
There is no set date for when Pi coins will enter the market.
However, the developers are working hard to get them released as soon as possible.
Once they are available, users will be able to exchange other cryptocurrencies for Pi coins on designated exchanges.
But for now the only way to sell your pi coins is through verified pi vendor.

how to sell pi coins in South Korea profitably.DOT TECH
Yes. You can sell your pi network coins in South Korea or any other country, by finding a verified pi merchant
What is a verified pi merchant?
Since pi network is not launched yet on any exchange, the only way you can sell pi coins is by selling to a verified pi merchant, and this is because pi network is not launched yet on any exchange and no pre-sale or ico offerings Is done on pi.
Since there is no pre-sale, the only way exchanges can get pi is by buying from miners. So a pi merchant facilitates these transactions by acting as a bridge for both transactions.
How can i find a pi vendor/merchant?
Well for those who haven't traded with a pi merchant or who don't already have one. I will leave the what'sapp number of my personal pi merchant who i trade pi with.

Recent version of the relative efficient market hypothesis states that "it is not possible to systematically earn
excess profits without some sort of competitive advantage”. (“Perspective in neural computing”)
Sophisticated modelling techniques, speed of elaboration are probably the “COMPETITIVE ADVANTAGE”
and have the potential to generate excess profits….
….as long as they are early adopted and kept confidential!

Confidential - all right reserved6
1. A robot may not injure a human being or, through inaction, allow a human being to come to harm.
2. A robot must obey any orders given to it by human beings, except where such orders would conflict
with the First Law.
3. A robot must protect its own existence as long as such protection does not conflict with the First or
Second Law.

20. Our approach to Pattern Recognition
Confidential - all right reserved
The intraday time series is a “trajectory” with a starting point (an eventual bias), an arrival destination, and
intermediate features exactly as a taxi ride
Exactly as a TAXI RIDE the trajectory destination can be influenced by:
• the hour of the day,
• day of the week,
• season of the year,
• events that can catalyse traffic (bias)
This comparison enable us to use the tools and results of the analytics
of movement.

Pascal & Bengio, Y. ,2015
21. Our approach to Pattern Recognition
Confidential - all right reserved21
We assume that there is a finite set of typical or “archetypal” trajectories (“market states”) that represent
intraday market behaviour.
These trajectories are created by the interactions of different players and different speed-moving capital
We design algorithms that can predict the “most probable” destination, looking at the partial trajectory at

22. Online forecasting
Confidential - all right reserved22
In the framework we have created, the challenge is to:
Find a good rappresentation
of the dataset in terms of
«typical» trajectories
Find a performing algorithm
to «learn» how to connect the
online observation with the «most
probable» trajectory for the day
Unsupervised methods for
clustering
Supervised methods for
forecasting (NN for classification,
SVM)
Better if done together.
And A.I. can do it.
23. Market Clock algorithms
Confidential - all right reserved23
In Market Clock, we currently use 5 different algorithms:
a dynamic K-means clustering
a K-means modified, proprietary version
a multilevel SVM classifier
a Deep Tapped Delay Line with enhanced clustering
a MLP for classification
Algorithms performances are
continuosly evaluated
New algorithms are added
if backtesting yields good results or
viceversa.

I. Time Series clustering
II. Deep Learning contribution
III. The Out-Performance shape
25. I. Time Series clustering
Confidential - all right reserved25
The nucleo of Market Clock is the general theme of time series clustering aimed at forecasting.
The problem arises whenever we observe a sample of time series and we want to group them into different
categories. This is particularly useful in finance. Generally, the notion of similarity used relies on two criteria:
Proximity between raw time (standard partitioning clustering)
Proximity between underlying processes (model based clustering)
We use proximity between raw time series after proper normalization in the machine learning algorithms
and model based clustering in the neural network framework.
“Time-series clustering – A decade review” Saeed Aghabozorgi Ali Seyed Shirkhorshidi TehYing Wah, 2015
26. II. Deep Learning contribution
Confidential - all right reserved26
Improve the clustering (optimized inside the neural network)
Weight the features based on their importance in forecasting daily evolution of returns
Gain more flexibility
27. III. Out-Performance Shape
Confidential - all right reserved27
Performances varies with the asset features; for a set of assets, realized performances in
backtesting are outstanding.

28. Is the Algorithm the «New Asset Allocation»?
Confidential - all right reserved28
• The combination trading strategy + algorithm works as a P&L regularizer in back testing, avoiding large
swing with a positive average return (figure below)
• Algo strategy could serve as an asset for portfolio allocation
Volatility of daily return: strategy vs underlying asset
These return distributions are exactly the same as the ones we saw before for
HFR and Eureka indexes

29. Agenda
Confidential - all right reserved29
Introduction to A.I.4Trading Project
New Techniques, New tools
From Technical Analysis to Pattern Recognition
From Factor Analysis to Autoencoders
30. Autoencoders
Confidential - all right reserved30
• Autoencoders are a comprehensive category of Neural Network
• In the process of rebuilding the input, they try to find an “informative representation” of the
original data.
• They represent the natural choice for modelling relative value in finance.
• They contain as special (linear) cases:
• Independent component analysis
• Clustering analysis
• Principal component analysis
• Archetypal analysis
They can be further generalized to take in account non linearities and probalistic
structure of the “hidden variables”
31. Python
Confidential - all right reserved31
# process file.txt and print
# all the words ending in ing
for line in open("file.txt"):
for word in line.split():
if word.endswith('ing'):
print word
• Simple yet powerful programming language
• Object-oriented: line is a string object so has a “method” split(),
word is a string object so has a “method” ends with with the
argument 'ing'
• Highly readable
• Shallow learning curve, facilitates interactive exploration, permits
data and methods to be encapsulated and re-used easily,
permits attributes to be added to objects on the fly, and permits
variables to be typed dynamically, facilitating rapid
development.
• Extensive standard library
• Heavily used in industry, scientific research, and education
32. PCA
Confidential - all right reserved32
• Dimensionality reduction technique: mapping
multidimensional data into a lower dimensional space
with minimal loss of information.
• First principal component: direction in space, along
which, projections have the largest variance
• Second principal component: direction, which maximizes
variance among all directions orthogonal to the first, and
so on…
𝑌 = 𝑊 ⋅ 𝑋 𝑋 = 𝑊 𝑇 ⋅ 𝑌
𝑉𝑎𝑟 𝑋 = 𝑊Λ𝑊 𝑇
𝑉𝑎𝑟 𝑌 = Λ
• In Python, just few lines of code
# imports the PCA class and finds a
# projection over 3 components
from sklearn.decomposition import PCA
n_comp = 3
pca = PCA(n_comp, whiten=False)
proj = pca.fit_transform(x_train)
print pca.components_.T
33. Autoencoder
Confidential - all right reserved33
• Neural Network trained to give as output the input itself
• Two networks: Encoder, Decoder
• Encoder extracts few features from the data
• Decoder reconstructs the data from the features
𝑌 = 𝜎1(𝑊1 ⋅ 𝑋 + 𝑏1)
𝑋 = 𝜎2 𝑊2 ⋅ 𝑌 + 𝑏2
• Can use nonlinearities to give better results
34. Implementation
Confidential - all right reserved34
• Encoder, no bias, tied weights
𝑌 = 𝑊 𝑇
⋅ 𝑋
• Decoder, simple matrix multiplication
𝑋 = 𝑊 ⋅ 𝑌
• Model, just call encoder inside
decoder
• Loss: MSE of the estimate
𝐸 ∥ 𝑋 − 𝑋 ∥2
= 𝐸[∥ 𝑋 − 𝑊 𝑇
(W ⋅ 𝑋) ∥2
]
# Building the encoder
def encoder(x):
layer_1 = x
layer_2 = tf.matmul(layer_1, tf.transpose(weights['decoder_h1']))
return layer_2
# Building the decoder
def decoder(x):
layer_1 = tf.matmul(x, weights['decoder_h1'])
layer_2 = layer_1
return layer_2
# Construct model
encoder_op = encoder(X)
decoder_op = decoder(encoder_op)
y_pred = decoder_op
# Define loss and optimizer, minimize the squared error
loss = tf.reduce_mean(tf.pow(y_true - y_pred, 2))
optimizer = tf.train.AdamOptimizer(learning_rate_v).minimize(loss)

Market Clock: performances assumptions
The P&L of the strategies are calculated as a passive strategy re-evaluated at each 30m time stamp.
The trading strategy consists of starting the position on the signal above/below a certain threshold,
keepening the position until the end of day and reverting it if signal changes.
The threshold is defined as a function of the forecast and its standard deviation.
Three zeta version have been tested, based on the forecasting horizon (next 30 minute or End of the
day):
Zeta_eod= (last_obs-forecast_eod)/std(forecast_eod)
Zeta_next= (last_obs-forecast_next)/std(forecast_next)
Zeta_star= (last_obs-forecast_eod)/std(forecast_next)
