Communication through e-mails remains to be highly formalized, conventional and indispensable method for the exchange of information over the Internet. An ever-increasing ratio and adversary nature of spam e-mails have posed a great many challenges such as uneven class distribution, unequal error cost, frequent change …

HapNet predicts marketing campaign effects using a hierarchical structure.

We consider the problem of classification when inputs correspond to sets of vectors. This setting occurs in many problems such as the classification of pieces of mail containing several pages, of web sites with several sections or of images that have been pre-segmented into smaller regions. We propose generalizations o…

Real-Time Bidding is nowadays one of the most promising systems in the online advertising ecosystem. In the presented study, the performance of RTB campaigns is improved by optimising the parameters of the users' profiles and the publishers' websites. Most studies about optimising RTB campaigns are focused on the biddi…

This paper enhances uplift modeling for multi-treatment marketing campaigns.

The paper tackles the issue of preferential attachment in targeted display advertising by developing domain-adaptation approaches.

Real time bidding (RTB) enables demand side platforms (bidders) to scale ad campaigns across multiple publishers affiliated to an RTB ad exchange. While driving multiple campaigns for mobile app install ads via RTB, the bidder typically has to: (i) maintain each campaign's efficiency (i.e., meet advertiser's target cos…

New method detects adversarial attacks in industrial systems.

Study uses causal machine learning to assess coupon campaign impact on retailer sales.

This paper optimizes ad bids and daily budgets for multiple campaigns in pay-per-click advertising.

The paper introduces revenue uplift modeling to maximize marketing profits.

Study analyzes factors influencing healthcare providers' engagement with SMS campaigns.

The paper tackles budget allocation for multiple campaigns using a novel combinatorial bandit approach.

A Qini-based uplift model improves retention marketing campaign performance.

PolicySynth improves synthetic data alignment with real data for better campaign decisions.

Activists align with large fund preferences for success.

Paper addresses CPA line forecasting in online advertising mid-flight.

Optimizes user marketing campaigns to balance cost and effectiveness.

Interpretation of a machine learning induced models is critical for feature engineering, debugging, and, arguably, compliance. Yet, best of breed machine learning models tend to be very complex. This paper presents a method for model interpretation which has the main benefit that the simple interpretations it provides …

The paper tackles decision making problems with funnel structure in email marketing campaigns.

This paper addresses the problem of inferring a regular expression from a given set of strings that resembles, as closely as possible, the regular expression that a human expert would have written to identify the language. This is motivated by our goal of automating the task of postmasters of an email service who use r…

The problem to accurately and parsimoniously characterize random series of events (RSEs) present in the Web, such as e-mail conversations or Twitter hashtags, is not trivial. Reports found in the literature reveal two apparent conflicting visions of how RSEs should be modeled. From one side, the Poissonian processes, o…

Framework detects influential actors in disinformation networks.

Mobile payment incentives optimized using merchant transaction networks.

Chagas disease is a neglected disease, and information about its geographical spread is very scarse. We analyze here mobility and calling patterns in order to identify potential risk zones for the disease, by using public health information and mobile phone records. Geolocalized call records are rich in social and mobi…

Given two compact hyperkähler surfaces $X$ and $Y$ and a holomorphic vector bundle $Q$ on $X\times Y$, which is a generalized instanton, one can define a Fourier-Mukai transform, which, under suitable assumptions, maps vector bundles on $X$ to vector bundles on $Y$. If $X$ and $Y$ are dual complex tori, this transform …

Study uses time series analysis to predict player churn and conversion in games.

Study optimal bidding strategies for digital ads targeting purchases and health campaigns.

A PID-based feedback-control system improves multiple KPIs in RTB display advertising.

It takes skill to build a meaningful predictive model even with the abundance of implementations of modern machine learning algorithms and readily available computing resources. Building a model becomes challenging if hundreds of terabytes of data need to be processed to produce the training data set. In a digital adve…

UCB algorithms estimate uplifts in multi-variable reward systems.

Steady progress has been made in abstractive summarization with attention-based sequence-to-sequence learning models. In this paper, we propose a new decoder where the output summary is generated by conditioning on both the input text and the latent topics of the document. The latent topics, identified by a topic model…

This study integrates cost-sensitive and causal classification methods.

In this paper, we attempt to improve Statistical Machine Translation (SMT) systems on a very diverse set of language pairs (in both directions): Czech - English, Vietnamese - English, French - English and German - English. To accomplish this, we performed translation model training, created adaptations of training sett…

The paper proves an obstruction to immersed curves with specific curvature.

A typical viral marketing model identifies influential users in a social network to maximize a single product adoption assuming unlimited user attention, campaign budgets, and time. In reality, multiple products need campaigns, users have limited attention, convincing users incurs costs, and advertisers have limited bu…

Proposes a greedy algorithm for telecom offers to retain subscribers.

SMC analysis reveals key transient effects in macroeconomic ABM.

A simple Ising spin model which can describe the mechanism of advertising in a duopoly market is proposed. In contrast to other agent-based models, the influence does not flow inward from the surrounding neighbors to the center site, but spreads outward from the center to the neighbors. The model thus describes the spr…

BiCB combines traffic prediction and bidding optimization for live advertising.

In the age of data driven solution, the customer demographic attributes, such as gender and age, play a core role that may enable companies to enhance the offers of their services and target the right customer in the right time and place. In the marketing campaign, the companies want to target the real user of the GSM …

Paper proposes TC3 algorithm to predict crowdfunding funding progress.

Reward learning enables the application of reinforcement learning (RL) to tasks where reward is defined by human judgment, building a model of reward by asking humans questions. Most work on reward learning has used simulated environments, but complex information about values is often expressed in natural language, and…
