86+
<p>Every day, millions of transactions between people or organizations
87+
take place, amongst which there might, just might, be some that are
88+
suspicious. Our job is to identify these transactions and why they do
89+
not fit a normal pattern. Hence, why we built our transaction
90+
monitoring platform. We will be talking about the reasons why this
91+
platform needed to be both generic and flexible and how we achieved
92+
this. We will go on to discuss:</p>
93+
<ul class="last simple">
94+
<li>Why different clients have different needs depending on the
95+
information they choose to store on their transactions. Why
96+
traditional SQL tables are not entirely suited to this application and
97+
why NoSQL is a natural alternative, as we still need all the
98+
traditional layers of validation and normalization of external input.</li>
99+
<li>The challenge of building an engine that is optimised to process
100+
large numbers of transactions, whilst at the same time being flexible
101+
enough to support all the different styles of analysis that are
102+
required to detect money laundering and terrorist financing.</li>
103+
<li>And in terms of performance how far you can take ORM and when it is
104+
acceptable to take matters into your own hands. Finally, we will
105+
discuss splitting business logic between python code and database
106+
queries.</li>

115+
<p class="last">Over the last three years deep learning has exploded in popularity and
116+
the quality of the results has greatly improved. Big tech companies
117+
have increased their research budgets in order to benefit from this
118+
revolution. As a direct consequence several of these (Microsoft,
119+
Google, Facebook, Amazon) have released open frameworks for training
120+
and developing deep architectures such as: TensorFlow, CNTK,
121+
FBLearner, MxNET and Caffe. Beside these, other popular existing
122+
frameworks and wrappers coming mainly from academia, have gathered a
123+
great deal of support (Theano, Torch7, Scikit-learn, Keras). With such
124+
a broad choice, it's no surprise that choosing the &quot;right&quot; Machine
125+
Learning (ML) framework can lead to a paradox of choice (especially
126+
for beginner ML students). This talk will give an overview of what ML
127+
frameworks are and what they do. We will discuss in more detail
128+
TensorFlow, Scikit-learn, Theano and Keras, highlighting the pros and
129+
cons for each of these frameworks. Finally, we will demonstrate them
130+
by applying them to a simple linear regression task.</p>

<p><strong>Persic Alexandru Cristian (Backend Lead)</strong> studied computer science at
140+
&quot;Stefan cel Mare&quot; University, followed by a masters degree in software
141+
engineering (apparently 5 years of study was not good enough). At
142+
university he started working at an outsource company using Microsoft
143+
technologies and enjoyed each step from helping with JavaScript to
144+
implementing custom workflows in SharePoint. After 5 years he saw the
145+
light and moved to Python/Django, building a mobile advertising
146+
platform from the ground up. In 4 years he managed to gain plenty of
147+
experience in managing the implementation, deployment and maintenance
148+
of a large scale web application. In 2016 Cristi made a daring move
149+
and joined ComplyAdvantage in the quest of finding once more the
150+
excitement of building a new and successful product, all the while
151+
fighting crime like any other regular superhero.</p>
152+
<p><strong>Ariel Pontes (Python Engineer)</strong> studied Computer Engineering at
153+
the Catholic University of Rio de Janeiro. After learning
154+
Python/Django in his first internship in a fintech startup he fell in
155+
love with MVC frameworks, and re-wrote his final year project in Ruby
156+
on Rails. In 2014 he moved to Cluj and started working as a full-stack
157+
Django developer in a big outsourcing company. Ariel joined
158+
ComplyAdvantage in 2016 where he works on the transaction monitoring
159+
and screening platforms. Outside of work you can find him
160+
participating in activism for local NGOs and preaching about secular
161+
ethics.</p>
162+
<p><strong>Oana Ratiu (Python Engineer)</strong> graduated from Babes-Bolyai
163+
University, Cluj-Napoca, studying computer science, and is currently
164+
completing her Master's Degree in Databases. She has worked as a
165+
programmer for three years, mostly with Python. Excited to fight
166+
terrorism through her work, Oana joined ComplyAdvantage in early 2016,
167+
working on a transaction monitoring platform and, more recently, on a
168+
screening platform.</p>
169+
<p><strong>Cristian Lungu (Senior Python/ML Engineer)</strong> wrote (anti)viruses for fun
170+
and profit for 5 years until he realised how much money flows through
171+
the stock market. He then spent his next 5 years coding derivatives,
172+
futures and options. Somehow, he was kidnapped and dropped on this
173+
startup ship called ComplyAdvantage where fighting terrorists and
174+
money laundering with machine learning is the only way to get a meal.
175+
As a result of this event, he challenged himself to actually finish
176+
his lifelong hobby, a PhD in machine learning, this century. When he
177+
doesn't code he's probably teaching bubble sort at the UTCN or
178+
conducting practical studies of gradient descent on some mountains.</p>
