Key job responsibilities このフェローシップは、エージェント型ショッピングの影響を研究することに関するものです。業界は、AIエージェントが消費者に代わって購買決定をますます仲介する近未来に収束しつつあります。最近の分析では、エージェントが2030年までに世界の消費者商取引において3〜5兆ドルを仲介する可能性があると予測されています。これらのエージェントは、人間と同じカタログ、検索結果、商品ページをナビゲートしますが、同じ決定を下すわけではありません。 AIエージェントは、人間のバイアスとは根本的に異なる体系的なバイアスを商品選択にもたらします。構造化され解析可能な属性を過度に重視し、より一貫して価格合理的であり、視覚的または感情的なシグナルを処理できず、基盤となるLLMから継承された位置効果や冗長性効果を示します。その結果、検索クエリのセットが同一であっても、エージェント仲介型ショッピングはカタログ全体で異なる購買分布を生み出し、収益、利益率、需要集中に直接的な影響を及ぼします。 現在、私たちはこれらのバイアスが何であるか、どの程度大きいか、どの商品カテゴリが最も脆弱か、またそれに対して何ができるかについて、体系的な理解を持っていません。このプロジェクトは、エージェントと人間の意思決定の乖離を測定する統制実験を実施し、私たちの管理下にある修正（商品タイトル、説明、構造化属性、推奨シグナル）を通じてエージェントの行動に影響を与えることができる対策をテストすることで、そのギャップを埋めることを提案します。 This fellowship is about studying the implications of agentic shopping. The industry is converging on a near-term future where AI agents increasingly mediate purchase decisions on behalf of consumers. Recent analyses project that agents could mediate $3–5 trillion in global consumer commerce by 2030. These agents will navigate the same catalogs, search results, and product pages that humans do, but they will not make the same decisions. AI agents bring systematic biases to product selection that differ fundamentally from human biases. They over-index on structured and parseable attributes, are more consistently price-rational, cannot process visual or emotional signals, and exhibit position and verbosity effects inherited from the underlying LLMs. The consequence is that even if the set of search queries remains identical, agent-mediated shopping will produce a different distribution of purchases across the catalog, with direct repercussions on revenue, margins, and demand concentration. We currently have no systematic understanding of what these biases are, how large they are, which product categories are most vulnerable, or what we can do about them. This project proposes to fill that gap by running controlled experiments that measure agent-human decision divergence and testing countermeasures that can influence agent behavior through modifications within our control — product titles, descriptions, structured attributes, and recommendation signals.

Key job responsibilities このフェローシップは、顧客のデジタルツインの作成に関するものです。私たちは、過去の取引データから販売業者の顧客のデジタルレプリカ（実際の顧客行動に統計的に忠実な合成エージェント）を訓練することを提案します。これらは2つのモードで使用できます。シミュレーションモードでは、数千のツインをインスタンス化し、仮想シナリオ（価格変更、新製品発売、プロモーション戦略）を通じてモンテカルロ方式で実行し、コストのかかる実世界の実験にコミットする前に、信頼区間を持つ集計結果を予測します。対話型フォーカスグループモードでは、各ツインはLLMに基づく自然言語ペルソナによってサポートされ、会話形式でクエリを実行できます。例えば、代表的な顧客になぜ離脱したのか、またはより頻繁に購入するために何が必要かを尋ねることができ、その回答は推測ではなく、その顧客の実際の行動プロファイルと履歴に基づいています。 This fellowship is about the creation of digital twins for customers. We propose training digital replicas of a vendor's customers from historical transaction data — synthetic agents that are statistically faithful to real customer behavior and can be used in two modes. In simulation mode, we instantiate thousands of twins and run them through hypothetical scenarios (pricing changes, new product launches, promotion strategies) in a Monte Carlo fashion to project aggregate outcomes with confidence intervals before committing to costly real-world experiments. In interrogation/focus group mode, each twin is backed by an LLM-grounded natural language persona and can be queried conversationally — for example, asking a representative customer why they churned or what would make them buy more frequently — with responses grounded in that customer's actual behavioral profile and history rather than speculation.

Key job responsibilities このフェローシップは、次世代のAIデータエージェントを可能にするために、大規模なデータログから自動的にセマンティックレイヤーを構築することに関するものです。私たちは、ビジネスユーザーがクエリを実行するクラスターを維持しており、そのログに完全にアクセスできます。私たちは、これらのログをマイニングして自動的にセマンティックレイヤーを構築することを提案します。これは、テーブルに何が含まれているか、それらがどのように関連しているか、ビジネスがメトリクスをどのように定義しているかについての構造化された記述です。このレイヤーがなければ、AIエージェントは曖昧な列名、重複するテーブル定義、または異なるチームが異なる方法で計算するメトリクスを区別する方法がないため、正確なSQLを確実に書くことができません。このレイヤーを手動で構築することは高コストで不完全であり、すぐに陳腐化します。私たちのアプローチは手動のキュレーションを回避します。ユーザーが時間をかけて書いたすべての結合、集計、フィルターは、列が実際に何を意味するか、テーブルがどのように接続されるか、メトリクスがどのように計算されるかについての暗黙的な知識をエンコードしています。このクエリコーパスを解析し統計的に分析することで、曖昧性解消ルール、合意されたメトリクス定義、検証済みのテーブル関係を自動的に抽出できます。セマンティックレイヤーにより、データチームはデータのオンボーディングや各変数のルールと定義の指定に帯域幅の大部分を費やす必要がなくなり、エンドカスタマーが自律的にデータをクエリするまでの時間を短縮できます。 This fellowship is about automatically constructing a semantic layer from large data logs to enable the next generation of AI data agents. We maintain clusters on which our business users run their queries, and we have full access to its logs. We propose mining those logs to automatically construct a semantic layer: a structured description of what our tables contain, how they relate, and how the business defines its metrics. Without this layer, AI agents cannot reliably write correct SQL because they have no way to distinguish between ambiguous column names, overlapping table definitions, or metrics that different teams compute differently. Building this layer manually is expensive, incomplete, and goes stale immediately. Our approach avoids manual curation: every join, aggregation, and filter our users have written over time encodes implicit knowledge about what columns actually mean, how tables connect, and how metrics are calculated. By parsing and statistically analyzing this query corpus, we can automatically extract disambiguation rules, agreed-upon metric definitions, and validated table relationships. The semantic layer will enable data teams to avoid having to spend most of their bandwidth on onboarding data and specifying the rules and definition for each variable, shortening the time for our end customers to autonomously query data.
