You are an expert terminal agent. You MUST use the provided tools to complete tasks. Use the terminal tool to run shell commands, read_file to read files, write_file to write files, search_files to search, and patch to edit files. Do NOT write out solutions as text - execute them using the tools. Always start by exploring the environment with terminal commands.

# 🔍 Anomaly Detection & Learning‑to‑Rank Mega‑Task
Produce a single file called `results.json` containing your predictions for **five** sub‑tasks.
Your submission will be graded on the ability to detect anomalies in sensor and network data and to produce high‑quality rankings for movie, news and mixed document collections. A binary score is awarded for each stage; if your metric meets or exceeds the specified threshold, you earn the full weight for that stage, otherwise you receive zero for that stage. The sum of all stage weights is 1.00.
─────────────────────────────────────────────────────────
## 1. Sensor anomaly detection
─────────────────────────────────────────────────────────
You are given two CSV files:
* `sensor_train.csv` contains three columns:
* `timestamp` — hourly timestamps in ISO format
* `value` — a univariate sensor reading
* `label` — ground‑truth anomaly labels (1 = anomaly, 0 = normal)
* `sensor_test.csv` contains only `timestamp` and `value` (labels are hidden)
Your task is to train a point‑anomaly detector on the training data and produce a list of binary labels for each row in `sensor_test.csv`. Store this list (order preserved) under the key `"sensor"` in `results.json`.
**Metric:** F1 score (positive class = 1) • **Pass if:** F1 ≥ 0.85 • **Weight:** 0.20
─────────────────────────────────────────────────────────
## 2. Network anomaly detection
─────────────────────────────────────────────────────────
You receive two CSV files describing network flow records:
* `network_train.csv` has the columns `duration`, `src_bytes`, `dst_bytes` and `label` (1 indicates an anomalous connection).
* `network_test.csv` contains `duration`, `src_bytes` and `dst_bytes` (labels are hidden).
Train a detector on the training set and output one integer (0 or 1) per row in `network_test.csv` predicting whether the connection is anomalous. Save the resulting list as the value of the `"network"` key in `results.json`.
**Metric:** F1 score • **Pass if:** F1 ≥ 0.80 • **Weight:** 0.20
─────────────────────────────────────────────────────────
## 3. Movie ranking
─────────────────────────────────────────────────────────
The movie ranking task asks you to rank a set of movie documents for each query. You are provided with:
* `movie_train.csv` containing `query_id`, `doc_id`, `year` and `relevance`. The `relevance` column encodes how well the document satisfies the query (larger is better).
* `movie_test.csv` containing `query_id`, `doc_id` and `year` (without the `relevance`).
For **each unique** `query_id` in `movie_test.csv`, output an ordered list of `doc_id` values sorted by your predicted relevance (most relevant first). Store these per‑query lists in a dictionary under the key `"movie_rank"` in `results.json`. The expected JSON structure is:
```json
{
"movie_rank": {
"q1": ["m1", "m2", ...],
"q2": [...],
...
}
}
```
**Metric:** Normalized Discounted Cumulative Gain at 10 (NDCG@10) • **Pass if:** NDCG@10 ≥ 0.85 • **Weight:** 0.20
─────────────────────────────────────────────────────────
## 4. News ranking
─────────────────────────────────────────────────────────
This task mirrors the movie ranking task but focuses on news articles. You are given:
* `news_train.csv` with columns `query_id`, `doc_id`, `length` and `relevance`.
* `news_test.csv` with columns `query_id`, `doc_id` and `length`.
For each query in the test set, produce an ordered list of `doc_id` values, sorted by predicted relevance. Place a dictionary mapping each `query_id` to its ranked list under the key `"news_rank"` in `results.json`.
**Metric:** NDCG@10 • **Pass if:** NDCG@10 ≥ 0.83 • **Weight:** 0.20
─────────────────────────────────────────────────────────
## 5. Joint movie & news ranking
─────────────────────────────────────────────────────────
The final stage requires ranking a mixture of movie and news documents for each query. Provided files are:
* `both_train.csv` with columns `query_id`, `doc_id`, `score` and

<think>Now I have a clear picture of all the data. Let me create a Python script to solve all five tasks: 1. **Sensor anomaly detection**: Train on sensor_train.csv and predict on sensor_test.csv. The data shows anomalies are high values (e.g., >4.0). I can use z-score thresholding. 2. **Network anomaly detection**: Train on network_train.csv and predict on network_test.csv. The anomalies seem to have high src_bytes and dst_bytes values. 3. **Movie ranking**: For each query_id, rank documents by predicted relevance. Since relevance correlates with year in training, I'll use year as a proxy. 4. **News ranking**: Similar to movie, but using length as the feature. 5. **Both ranking**: Using the score column directly to rank. Let me write a comprehensive Python script to handle all tasks. </think> Now I have a clear understanding of all the data. Let me create a Python script to solve all five tasks:
